• Athletic performance. Oral beet may improve athletic performance associated with aerobic activities. However, it is not clear who is most likely to benefit, for which type of competition it is most useful, or what dose or duration of use is most appropriate. Details: Several small clinical trials, most of which enrolled elite athletes, recreational athletes, and sedentary males, as well as meta-analyses of some of these and other studies, show that beet improves various measures of athletic performance, including ability, muscular endurance, power output, sprinting, and strength (93844,94464,94468,94469,100143,100150,100152,105761,113422). Clinical research also shows that drinking beetroot juice improves the use of oxygen during exercise testing in recreationally-trained athletes, especially with severe exercise testing (94460,94463,94467,100147,105762). Also, in obese adolescents, taking beetroot juice daily for 6 days increases the time to exhaustion from severe exercise, but does not improve moderate exercise (100145). Not all research shows that beet supplementation benefits athletic performance. Another meta-analysis of several small clinical studies, including some of the studies above, shows that taking beetroot does not improve performance in high-intensity or sprint interval training (111159). Additionally, the majority of research in elite athletes does not support the use of beetroot juice to decrease the time needed to complete a task, aid in some sort of graded exercise test, or improve the use of oxygen during exercise testing (94455,94458,94460,94461,94464,94465,94466,94469,94473,100142,100153,105763). The supposed lack of effect of beetroot juice in elite athletes might be related to the natural production of nitrates and nitrites in the body or the increased ability to use oxygen that comes from extensive training (94458,94463). Alternatively, any changes might be very small (<1%) and not identified with statistical comparisons, although even very small changes might be beneficial in competition (94464). The most commonly used doses in all studies, regardless of effect, have included an acute dose of beetroot juice 70-500 mL up to 3 hours prior to exercise (93844,94463,94464,94466,94467,94473,97726,100142,100143,105761)(105762,111159,113422) or chronic dosing of up to 500 mL daily for 3-6 days (94459,94464,94469,100145,100147,100153,111159,113422). Less commonly, beetroot juice 70-140 mL daily, betalain-rich concentrate 100 mg daily, or a beetroot-based nutritional gel 100 grams daily, have been taken for longer dosing schedules of 7-15 days (97720,100144,100148,100152,105763,113422). Benefits in elite athletes, most often related to time trials, are usually limited to studies using chronic dosing of 7-15 days, which is longer than the duration of 6 days used in the majority of studies (94473,97720,100144,100148). Brands of juice used in clinical trials have included Beet It Sport (James White Drinks Ltd.) (94455,94458,94465,100142,100143,100144,100148,105761,105763), Beet It Stamina Shot (James White Drinks Ltd.) (93844), Beet It (James White Drinks Ltd) (94457,94459,94460,94467,94469,97726,100145,100153,105762,111159), and Love Beets Beetroot Juice (Gs Fresh Ltd.) (94461,94462). Although plasma levels have not been analyzed in all studies, the majority of studies suggest that these doses are adequate to increase levels of nitrates or nitrites, which is thought to be essential for increasing athletic potential (93844,94455,94458,94459,94460,94465,94467,94469,94466,94473,97726). The evidence also suggests benefit in both normoxic and hypoxic environments (94465,100148,105763).
• Exercise-induced muscle soreness. Drinking beetroot juice 7-8 times over 48 hours after strenuous exercise may reduce exercise-induced muscle soreness, but evidence is conflicting. Details: Some clinical research shows drinking beetroot juice (Love Beets Beetroot Juice, Gs Fresh Ltd.) 125 mL or 250 mL seven times over 48 hours after strenuous box jumps improves muscle soreness when compared with placebo and sodium nitrite (96964,97722). Other small clinical studies show that drinking beetroot juice 50-250 mL as eight separate doses over 48 hours after strenuous exerciseimproves muscle soreness and reduces tissue edema when compared with placebo (94461,113424). However, drinking beetroot juice 250 mL as seven separate doses over 48 hours after running a marathon does not appear to reduce muscle soreness when compared with placebo (94462). A meta-analysis of 4 small studies, mostly in healthy or physically active males, shows that drinking beetroot juice improves the pressure pain threshold, which is a measure of muscle soreness, at 48- and 72-hours post-exercise when compared with a fruit-flavored drink. However, beetroot juice does not improve subjective muscle soreness scores (111160). The validity of the findings from this meta-analysis is limited by the heterogeneity of the beetroot juice regimens among the included studies. Further, these results should not be generalized to elite athletes.

POSSIBLY INEFFECTIVE

• Chronic obstructive pulmonary disease (COPD). Drinking beetroot juice for up to 14 days may not improve exercise capacity in patients with COPD. Details: A meta-analysis of eight small clinical trials in patients with COPD shows that taking nitrate-rich beetroot juice does not improve most measures of exercise capacity, including the 6-minute walk test, cycling ergometry endurance time, and maximum rate of oxygen consumption (VO2 max), when compared with placebo. Additionally, beetroot juice did not reduce blood pressure or heart rate. However, the analysis did show a significant improvement in scores on the Borg Rating of Perceived Exhaustion scale with beetroot juice over placebo. Nitrate-rich beetroot juice doses ranged from 70-140 mL daily for up to 14 days (104200).

• Cognitive function. It is unclear if drinking beetroot juice is beneficial for cognitive function. Details: A small clinical study in adults with overweight or obesity on a calorie-restricted diet shows that drinking 70 mL of concentrated beetroot juice daily for 14 days improves the time to complete part B of the trail making test, which is a test of cognitive function, but not part A, when compared with controls (111158). However, the duration and size of this study limits its validity. Further, it is unclear whether any improvement is clinically significant. The effect of acute beet administration on cognitive function has also been studied. A very small clinical study in healthy adults shows that taking beet extract (RedNite, Enovate Biolife) chewable tablets 3 grams 90 minutes prior to neuropsychological testing improves immediate and delayed memory capacity, frontal lobe function, and lexical flexibility but does not improve working memory, information processing speed, or subjective reports of memory performance when compared with placebo (113427).
• Coronary heart disease (CHD). It is unclear if oral beetroot extract is beneficial in patients with CHD. Details: A small clinical trial in patients with CHD shows that taking red beetroot extract 500 mg, containing around 25 mg betalains, twice daily for 2 weeks reduces total cholesterol and low-density lipoprotein (LDL) cholesterol by 15 mg/dL and reduces triglycerides by 8 mg/dL when compared to baseline. Slight improvements in blood pressure and blood glucose were also reported, but these changes were not clinically significant (103883). The validity of these findings is limited by the lack of a comparator group. Also, it is unclear whether beetroot can reduce the risk of cardiovascular events in patients with CHD.
• Dyslipidemia. It is unclear if oral beetroot is beneficial in patients with dyslipidemia. Details: A meta-analysis of small clinical studies in healthy individuals or patients with dyslipidemia, cardiovascular disease, or overweight or obesity, shows that consuming beetroot juice or leaves does not improve levels of triglycerides or total, low-density lipoprotein, or high-density lipoprotein cholesterol when compared with controls (111163). However, the validity of the findings from this meta-analysis is limited by the heterogeneity of the enrolled patients and beetroot regimens.
• Exercise-induced muscle damage. It is unclear if oral beetroot juice improves recovery from muscle damage after exercise. Details: A meta-analysis of 4 small clinical studies in healthy or physically active individuals, most of which enrolled males only, shows that drinking beetroot juice improves measures of muscle recovery at 72 hours post-exercise when compared with a fruit-flavored drink. However, beetroot juice does not consistently improve recovery at earlier time points post-exercise, nor does it reduce levels of creatine kinase or markers of inflammation (i.e., interleukin-6, interleukin-8, c-reactive protein, or tumor necrosis factor-alpha) (111160). However, the validity of the findings from this meta-analysis is limited by the heterogeneity of the beetroot juice regimens among the included studies, which usually varied from 210-250 mg of nitrate in 7-11 servings over 3-7 days. Further, these results should not be generalized to elite athletes. Another very small clinical study in semi-professional female athletes shows that ingesting beetroot juice 50 mL 8 times over 48 hours after exercise-induced muscle damage enhances the recovery of some functional parameters such as muscle endurance but not others such as flexibility and vertical jump performance when compared with placebo (113424).
• Hypertension. Oral beet may slightly reduce blood pressure in healthy individuals, but it is unclear if it is beneficial in patients with hypertension. Details: Meta-analyses of small studies show the potential for a minor reduction in systolic blood pressure (SBP) and diastolic blood pressure (DBP) in healthy adults taking beetroot juice (94470,97718,97728). The average reduction in SBP and DBP with beetroot juice consumption is about 4 mmHg and 1 mmHg, respectively, which is greater than the effect seen with consuming blackcurrant juice or nitrate-depleted beetroot juice. The most benefit is seen when beetroot juice is taken for at least 2 weeks or at doses of 500 mL daily (97728). The effect of acute beet supplementation on blood pressure is conflicting. A small clinical study in healthy adults shows that drinking beet juice (Beet It, James White Company) 140 mL two hours prior to cardiovascular measurements reduces resting SBP by about 4 mmHg but does not improve resting or post-exercise DBP, central blood pressure, or arterial stiffness nor does it improve post-exercise SBP when compared with placebo. Subgroup analysis suggests that the reductions in resting SBP were only observed in males, not females (113423). Another small clinical study shows that consuming beet 100 grams baked into bread modestly decreases DBP over a 6-hour period when compared with white bread (97725). It is possible that genetics might play a role in the magnitude of effect seen with beetroot consumption. Adults with a specific gene polymorphism, eNOS Glu298Asp, experienced a greater reduction in DBP after consuming beet-containing bread (97724). Despite positive findings in studies of healthy individuals, research on the use of beetroot juice in patients with hypertension is unclear. A small clinical study in adults with hypertension who were taking antihypertensive medications shows that drinking nitrate-rich beetroot juice (Beet it; James White Drinks Ltd.) 70 mL twice daily for one week does not lower blood pressure when compared with nitrate-depleted beetroot juice (94457). Also, in patients with mild to moderate hypertension, clinical research shows that taking a combination of beetroot powder (Sensient) 300 mg, olive leaf extract 1000 mg, and green coffee bean extract 200 mg daily for 6 weeks does not lower blood pressure when compared with placebo (97723). However, some evidence suggests that at least part of the blood pressure lowering effects of beet might be independent of nitrate (97728). Furthermore, some research suggests that identifying effects on blood pressure might be dependent on the method of measurement, including clinic resting measurements, 24-hour monitoring, or morning/evening home resting measurements (97729).
• Hypertriglyceridemia. It is unclear if oral beet is beneficial in patients with hypertriglyceridemia. Details: A small clinical study in overweight or obese individuals with dyslipidemia shows that taking freeze-dried beet leaf 2.8 grams daily for 4 weeks in addition to nutritional guidance does not lower triglyceride levels when compared with nutritional guidance alone (100146). Beet has also been evaluated in combination with other ingredients. A small clinical trial in patients at risk for heart disease shows that a specific combination of beet and hawthorn berry (Neo40-Daily, Neogenis Labs), taken twice daily for 30 days, can modestly reduce blood triglyceride levels when compared to baseline (18222). It is unclear if these findings are due to beet, hawthorn berry, or the combination.
• Liver disease. Although there has been interest in using oral beet for liver disease, there is insufficient reliable information about the clinical effects of beet for this purpose.
• Muscle strength. It is unclear if oral beetroot juice is beneficial for muscle strength. Details: A meta-analysis of 18 clinical studies in healthy males shows that taking beetroot juice or beetroot gel 2-3 hours before exercise improves muscular strength when compared with placebo. Subgroup analysis suggests that beetroot-based supplements improve muscular strength in a fatigued but not resting state (113422). A small clinical study in adults with overweight or obesity on a calorie-restricted diet shows that drinking 70 mL of concentrated beetroot juice daily for 14 days improves handgrip strength by approximately 18% compared with 4% in controls (111158). However, it is unclear whether any improvement is clinically significant.
• Obesity. It is unclear if oral beet leaf or beetroot juice is beneficial for weight loss. Details: A small clinical study in patients with overweight or obesity and dyslipidemia shows that taking freeze-dried beet leaf 2.8 grams daily for 4 weeks in addition to nutritional guidance does not reduce body weight or body mass index (BMI) when compared with nutritional guidance alone (100146). Similarly, a small clinical study in adults with overweight or obesity on a calorie-restricted diet shows that drinking 70 mL of concentrated beetroot juice daily for 14 days does not improve weight loss when compared with controls (111158). However, the size and duration of this study may have been inadequate to detect differences between groups.
• Pregnancy-induced hypertension. It is unclear if oral beetroot juice is beneficial in patients with pregnancy-induced hypertension. Details: A small clinical trial in pregnant patients with hypertension who are at approximately 22-35 weeks gestation shows that taking beetroot juice (James White Drinks Ltd) 70 mL daily for 8 days does not reduce blood pressure when compared with a nitrate-depleted beetroot juice (100151). However, the study was small and designed to investigate the feasibility of using beetroot juice in this population.
• Pulmonary hypertension. It is unclear if oral beetroot juice is beneficial in patients with pulmonary hypertension. Details: A small clinical study shows that taking beetroot juice (Beet-It Sport; James White Drinks Ltd) 70 mL twice daily for 7 days does not improve right ventricular systolic function when compared with nitrate-depleted beetroot juice in patients with pulmonary hypertension (100149). However, this study was small and not adequately powered to detect differences between groups.
• Raynaud syndrome. It is unclear if oral beetroot juice is beneficial in patients with Raynaud syndrome. Details: A small clinical study in patients with Raynaud syndrome undergoing cold sensitivity tests shows that drinking beetroot juice (Beet-It, James White Drinks Ltd) 70 mL daily for 13 days, followed by 140 mL prior to testing, does not reduce pain in the hands or feet, but might improve thermal comfort in the feet, when compared to baseline (103884). The validity of this finding is limited by the lack of a comparator group. More evidence is needed to rate beet for these uses.

• Vitamin A deficiency. Some preliminary clinical research shows that consuming one spoonful of carrot jam daily for 10 weeks improves growth velocity when compared with control in children with vitamin A deficiency (25819). Other preliminary research shows that consuming 100 grams of grated carrot daily for 60 days improves vitamin A status when compared with placebo in lactating women at risk for vitamin A deficiency (67861).

• Breast cancer. A meta-analysis of observational research has found that consuming a diet highest in carrots is associated with a 21% decreased odds of developing breast cancer when compared with consuming a diet lowest in carrots (101715).
• Colorectal cancer. A large observational study in older Danish adults shows that self-reported high consumption of raw carrot (2-4 carrots weekly or greater than 32 grams daily) is associated with a 17% lower likelihood of colorectal cancer diagnosis, whereas lower carrot consumption is not associated with a decreased risk. The validity of these findings may be limited by selection bias, recall bias, and other confounding factors (106559).
• Fibromyalgia. Preliminary clinical research shows that consuming a mostly raw, pure vegetarian diet that includes two to four 240 mL servings of carrot juice daily for 7 months might improve fibromyalgia symptoms in some people (98057). The effect of carrot alone on fibromyalgia is unknown.
• Prostate cancer. Population research has found that higher intake of carrot is associated with an 18% decrease in the odds of developing prostate cancer. Increasing carrot consumption by 10 grams daily or 1 serving per week is associated with a 4% to 5% decrease in the odds of developing prostate cancer (96307). More evidence is needed to rate carrot for these uses.

• Anxiety. It is unclear if oral celery seed extract is beneficial in patients with anxiety. Details: A small clinical study in Iranian adults with hypertension on standard antihypertensive therapy shows that taking celery seed extract 1.34 grams daily for 4 weeks reduces symptoms of anxiety and depression when compared with placebo (112409). However, it is unclear if these benefits can be extrapolated to patients in geographic locations other than Iran.
• Depression. It is unclear if oral celery seed extract is beneficial in patients with depression. Details: A small clinical study in Iranian adults with hypertension on standard antihypertensive therapy shows that taking celery seed extract 1.34 grams daily for 4 weeks reduces symptoms of anxiety and depression when compared with placebo (112409). However, it is unclear if these benefits can be extrapolated to patients in geographic locations other than Iran.
• Diabetes. It is unclear if oral celery seed extract is beneficial in patients with diabetes. Details: A small clinical study in adults with type 2 diabetes shows that taking celery seed powder 250 mg three times daily for 12 weeks does not improve fasting blood glucose, fasting insulin, insulin resistance, total cholesterol, low-density lipoprotein or high-density lipoprotein cholesterol, triglycerides, or blood pressure when compared with placebo (112411). However, the study may have been inadequately powered to detect a difference between groups.
• Dysmenorrhea. Oral celery seed has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical trial in female college students shows that taking a specific combination product containing celery seed, saffron, and anise extracts (SCA, Gol Daro Herbal Medicine Laboratory) 500 mg three times daily for 3 days, starting at the beginning of bleeding or pain, reduces severity and duration of pain symptoms associated with menstruation when compared with placebo (17214). It is not clear if these effects are due to celery, other ingredients, or the combination.
• Dyspepsia. Oral celery seed has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A moderate-sized clinical trial in adults with functional dyspepsia conducted in Iran shows that taking celery seed powder 500 mg daily with bishop's weed 500 mg daily spread over three doses after meals for 4 weeks reduces patient-reported dyspepsia symptom severity when compared with domperidone. Taking celery and bishop's weed also reduces patient-reported symptom frequency when compared to baseline (112410). However, it is unclear if these effects are due to celery, bishop's weed, or the combination, or if results can be extrapolated to patients in geographic locations other than Iran. The interpretation of these results is also limited by the lack of a placebo group.
• Gout. Oral celery has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small, open-label clinical study in patients with gout shows that taking a specific combination product (GoutFigher, Max Biocare) containing celery seed extract 600 mg, devil's claw root extract 300 mg, sour cherry extract 200 mg, and other ingredients twice daily for 45 days reduces pain, joint inflammation, and uric acid levels when compared to baseline (106488). The validity of these findings is limited by the lack of a control group. Additionally, it is unclear if these findings are due to celery, other ingredients, or the combination.
• Headache. Although there has been interest in using oral celery for headache, there is insufficient reliable information about the clinical effects of celery for this purpose.
• Hypertension. It is unclear if oral celery seed extract is beneficial in patients with hypertension. Details: A small clinical study in Iranian adults with hypertension on standard antihypertensive therapy shows that taking celery seed extract 1.34 grams daily for 4 weeks reduces daytime systolic blood pressure by about 12 mmHg compared to less than 1 mmHg with placebo. Celery seed extract also reduces night-time blood pressure, diastolic blood pressure, and mean arterial pressure, but does not impact the heart rate (110755). However, it is unclear if these benefits can be extrapolated to patients in geographic locations other than Iran.
• Impaired glucose tolerance (prediabetes). It is unclear if oral celery leaf extract is beneficial in patients with prediabetes. Details: A small clinical study in elderly patients with prediabetes shows that taking celery leaf extract 250 mg three times daily for 12 days reduces postprandial plasma glucose levels, but not insulin levels, when compared to baseline (99572). Although a control group was included in the study, statistical comparisons between treatment and control groups were not reported.
• Mosquito repellent. It is unclear if topical celery seed extract is beneficial for use as a mosquito repellant. Details: One small clinical study shows that applying gel formulations containing celery seed extract 5% to 25% can repel mosquitos in a dose-dependent manner for up to 4.5 hours. These formulations show similar repellant action when compared with DEET-containing formulations and appear to be superior to commercial repellants without DEET (40988). Celery extract has also been evaluated in combination with other ingredients. Two clinical studies show that application of a specific formulation (G10, E.A.R. Samunpri) containing celery seed extract 5%, along with vanillin, eucalyptus oil, orange oil, and citronella oil, seems to repel mosquitos for up to 4.5 hours comparably to other commercial products, including DEET 25% and Insect Block 28 (41049,41052). It is unclear if these findings are due to celery, other ingredients, or the combination.
• Osteoarthritis. Oral celery seed has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small, open-label clinical study in patients with mild knee osteoarthritis shows that taking a specific combination product (Tregocel, Max Biocare) providing celery seed 1000 mg, Boswellia serrata resin extract 1000 mg, devil's claw 1000 mg, ginger rhizome 330 mg, and curcumin 180 mg daily for 36 weeks reduces pain, improves functional capacity, and increases walking distance when compared to baseline (106078). The validity of these findings is limited by the lack of a control group. Additionally, it is unclear if these findings are due to celery, other ingredients, or the combination.
• Rheumatoid arthritis (RA). Although there has been interest in using oral celery juice for RA, there is insufficient reliable information about the clinical effects of celery for this purpose.
• Sexual dysfunction. It is unclear if oral celery seed powder is beneficial in females with sexual dysfunction. Details: One small clinical study in females with sexual dysfunction shows that taking celery seed powder 500 mg three times daily for 6 weeks improves sexual dysfunction symptom scores, primarily due to patient-rated improvements in sexual desire, arousal, lubrication, and pain, when compared with placebo (106486).
• Urinary tract infections (UTIs). Although there has been interest in using oral celery juice for UTIs, there is insufficient reliable information about the clinical effects of celery for this purpose. More evidence is needed to rate celery for these uses.

• Memory. Oral rosemary seems to improve memory in young adults. It is unclear if rosemary aromatherapy improves memory. Details: Clinical research in healthy adults shows that taking rosemary 500 mg orally twice daily for one month improves memory by approximately 14% when compared with placebo (98536). Other preliminary clinical research shows that applying four drops of pure rosemary essential oil (Tisserand Aromatherapy) to an aromatherapy diffuser pad 5 minutes before a single test period can improve the quality, but not the speed, of memory recall, and increase alertness and contentment more than lavender aromatherapy or no aroma (18323). Rosemary aromatherapy has also been evaluated for improving memory in adults with kidney failure. A small clinical study in patients (mean age 53 years) undergoing hemodialysis shows that aromatherapy with rosemary essential oil three times weekly for 1 month does not improve medication adherence or measures of prospective and retrospective memory when compared with a control group. In this study, five drops of rosemary essential oil were applied to gauze, which was then placed 10 cm from the patient's nose for 30 minutes starting 1 hour after hemodialysis (109559).

• Abortion. Although there has been interest in the use of oral rosemary as an abortifacient, there is insufficient reliable information about the clinical effects of rosemary for this purpose.
• Age-related cognitive decline. It is unclear if oral rosemary is beneficial for age-related cognitive decline. Details: A small clinical study in healthy individuals aged 65-90 years shows that a single 750 mg dose of powdered rosemary leaf in tomato juice may improve memory speed. However, higher single doses of 1500-6000 mg seem to have a deleterious effect on memory speed. For other measures of attention and memory, there were no clear benefits across the range of doses from 750-6000 mg (18246). Oral rosemary has also been evaluated in combination with other ingredients. A small clinical study in healthy adults aged 62 years or younger shows that taking a combination product containing equal parts rosemary, lemon balm, and sage twice daily for 2 weeks modestly improves word recall when compared with placebo. However, it does not appear to have benefit in adults aged 63 years and older (97277). It is unclear if any benefit is due to rosemary, other ingredients, or the combination.
• Alopecia areata. Topical rosemary oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that rosemary oil 114 mg, in combination with lavender oil 108 mg, thyme oil 88 mg, and cedarwood oil 94 mg, mixed with jojoba oil 3 mL and grapeseed oil 20 mL and applied topically to the scalp, improves hair growth in 44% of patients, compared with 15% of those receiving placebo. This combination was massaged into the scalp for a minimum of 2 minutes, followed by wrapping the head in a warm towel, every night for 7 months (5177).
• Androgenic alopecia. It is unclear if topical rosemary is beneficial for androgenic alopecia. Details: Preliminary clinical research shows that applying rosemary oil (Barij Essence Pharmaceutical Company) 1 mL to the scalp twice daily for 6 months is as effective as minoxidil 2% for increasing hair count in patients with androgenic alopecia (91729).
• Depression. It is unclear if oral rosemary is beneficial for major depressive disorder. Details: A small clinical trial among adults newly diagnosed with major depressive disorder and recent initiation of antidepressant medication shows that taking rosemary dried leaf extract 650 mg twice daily for 8 weeks might reduce some symptoms of depression and anxiety when compared with placebo (112141). However, the validity of these findings is limited by differences in baseline depression symptom scores between groups.
• Diabetes. It is unclear if oral rosemary is beneficial for improving glycemic control in patients with type 2 diabetes. Details: In patients with type 2 diabetes, preliminary clinical research shows that taking rosemary tea daily for 90 days decreases glycated hemoglobin levels by 15% and waist and hip circumference by 6% and improves insulin resistance. However, there was no effect on fasting blood glucose, lipid profile, body weight, or body mass index (BMI). The tea was made by adding rosemary 2 grams to a liter of boiling water for 3 minutes and then passing through a sieve (105323). Other preliminary clinical research in adults with type 2 diabetes shows that taking rosemary powder 3 grams daily for 4 weeks does not reduce fasting blood glucose levels or improve lipid profile when compared with baseline. These endpoints were improved in a group of healthy adults (105327). The validity of the findings from these studies is limited by the lack a comparator group.
• Diabetic nephropathy. Oral rosemary has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific combination product (Canephron N, Bionorica) containing 18 mg each of rosemary leaf, centaury herb, and lovage root per tablet, as two tablets three times daily for 6 months along with standard antidiabetes treatment and enalapril (Vasotec), decreases microalbuminuria by 73%, decreases albumin:creatinine ratio by 46%, increases high-density lipoprotein (HDL) cholesterol by 25%, and lowers triglyceride levels by 43%, but does not improve glomerular filtration rate, when compared to baseline. Improvements were greater in those taking the combination product than in those treated only with standard antidiabetes therapy and enalapril. However, the combination product does not appear to improve reductions in total cholesterol or low-density lipoprotein (LDL) cholesterol (91726).
• Dysmenorrhea. It is unclear if oral rosemary is beneficial for dysmenorrhea. Details: In patients with moderate primary dysmenorrhea, clinical research shows that taking rosemary extract 220 mg every 8 hours for the first three days of the menstrual cycle, repeated for two menstrual cycles, is as effective as mefenamic acid for reducing average pain and bleeding when compared with two baseline cycles (105328).
• Fatigue. Oral rosemary has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in healthy young adults with below-average energy levels shows that taking a single dose of a mixture of rosemary from Albania (Rosmarinus officinalis) and Morocco (Rosmarinus eriocalyx) 1.7 grams does not consistently improve sustained attention, motivation to perform cognitive tasks, mental energy, or mental fatigue when compared with placebo (91731).
• Fibromyalgia. Oral rosemary has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with fibromyalgia shows that taking an oral product containing rosemary leaf extract, oleanolic acid from olive leaf, and rho iso-alpha acids from hops (Meta050, Metagenics), at a dose of 440 mg three times daily for 4 weeks, then 880 mg twice daily for 4 weeks, does not improve symptoms when compared to baseline (18327).
• Gingivitis. A mouth rinse containing rosemary has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with mild to moderate gingivitis and mild plaque shows that rinsing the mouth with 10 mL of mouthwash containing 5% v/v of a combined alcoholic extract of rosemary, calendula, and ginger for 30 seconds twice daily after meals for 2 weeks decreases plaque formation, gingival inflammation, and gingival bleeding similarly to chlorhexidine gluconate 0.2% mouthwash and better than a placebo mouthwash (93555).
• Hypertension. Although there is interest in using oral rosemary for hypertension, there is insufficient reliable information about the clinical effects of rosemary for this condition.
• Hypotension. It is unclear if oral rosemary is beneficial for hypotension. Details: Preliminary clinical research in patients with primary hypotension shows that taking rosemary essential oil (Metapharmaceutical) 1 mL every 8 hours for 44 weeks increases systolic blood pressure by 13 mmHg and diastolic blood pressure by 7 mmHg when compared to baseline. However, blood pressure returned to near baseline values after treatment discontinuation (91730).
• Mental alertness. It is unclear if rosemary aromatherapy is beneficial for improving mental alertness. Details: Preliminary clinical research in nurses working on a night shift shows that placing one drop of rosemary oil on a surgical mask that is worn for 2 hours with a 10-minute on/15-minute off cycle modestly increases alertness and reduces sleepiness when compared with a water drop control (105324).
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral rosemary leaf is beneficial in patients with NAFLD. Details: A small clinical study in patients with NAFLD shows that taking rosemary leaf powder 2 grams twice daily for 8 weeks, in conjunction with diet and exercise recommendations, does not improve measures of liver function, glycemic control, cholesterol, or body weight when compared with placebo (109561).
• Opioid withdrawal. It is unclear if oral rosemary is beneficial for opioid withdrawal when used in combination with methadone. Details: Preliminary clinical research shows that taking rosemary leaf along with methadone for 2 weeks improves symptoms of opioid withdrawal and the ability to sleep when compared with methadone alone after 3 and 7 days of treatment, but not after 2 weeks. Rosemary leaf was provided in capsules containing 300 mg each (Barij Essence Pharmaceutical Company) at a dose of 16 capsules daily for the first 3 days, 12 capsules daily for the next 4 days, and eight capsules daily for the next 7 days, in divided doses (91727).
• Osteoarthritis. Oral rosemary has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows subjective reductions in pain associated with osteoarthritis when oral formulations containing rosemary leaf extract, oleanolic acid from olive leaf, and rho iso-alpha acids from hops (NG440-2, Metagenics; Meta050, Metagenics) are used (18326,18327). The formulation used in one of these studies (Meta050, Metagenics) was taken in a dose of 440 mg three times daily for 4 weeks, then 880 mg twice daily for 4 weeks (18327). The formulation used in the other study, which was taken daily for 4 weeks, contained rosemary leaf extract 112.5 mg, oleanolic acid from olive leaf 1 mg, and rho iso-alpha acids from hops 225 mg per tablet (18326).
• Raynaud syndrome. It is unclear if topical rosemary essential oil is beneficial in patients with Raynaud syndrome. Details: A very small, open-label study in patients with Raynaud syndrome caused by systemic scleroderma shows that applying 10 drops of rosemary 10% essential oil to the hands does not increase skin temperature or improve warmth perception when compared with olive oil (109560). However, this study may have been inadequately powered to detect a difference between groups.
• Rheumatoid arthritis (RA). Oral rosemary has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows subjective decreases in pain associated with RA when oral formulations containing rosemary leaf extract, oleanolic acid from olive leaf, and rho iso-alpha acids from hops (NG440-2, Metagenics; Meta050, Metagenics) are used (18326,18327). The formulation used in one of these studies (Meta050, Metagenics) was taken in a dose of 440 mg three times daily for 4 weeks, then 880 mg twice daily for 4 weeks (18327). The formulation used in the other study, which was taken daily for 4 weeks, contained rosemary leaf extract 112.5 mg, oleanolic acid from olive leaf 1 mg, and rho iso-alpha acids from hops 225 mg per tablet (18326).
• Stress. It is unclear if rosemary aromatherapy is beneficial for stress. Details: Preliminary clinical research on the use of rosemary aromatherapy for anxiety and stress is conflicting. In a group of graduate nursing students, perceived stress associated with taking a test was lower when inhalers containing rosemary or lavender oil were used. Three drops of rosemary essential oil were added to an inhaler and inhaled before and during the test. Pulse rates, but not blood pressure, were also reduced (18324). In contrast, a small clinical study in adults aged 18-30 years shows that the aroma from diluted rosemary essential oil applied to the wrist during timed crossword puzzle completion actually increases subjective feelings of anxiety and tension when compared with placebo (18325).
• Sunburn. Oral rosemary has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a combination of rosemary and grapefruit extracts in a 1:1 ratio (NutroxSun, Monteloeder, Inc.), 250 mg orally once daily for 12 weeks, increases the amount of UV radiation needed to cause sunburn by 34% after 8 weeks and 56% after 12 weeks when compared to baseline (91728). The validity of these findings is limited by the lack of a comparator group.
• Upper respiratory tract infection (URTI). Oral rosemary has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial among healthy adults shows that taking a combination product containing rosemary leaf extract, aloe gel powder, and poria mushroom extract daily for 8 weeks does not reduce the frequency, duration, or severity of URTI-related symptoms when compared with placebo. However, in patients receiving an influenza vaccine midway through the study, this product does seem to improve some immune response biomarkers when compared with placebo (111921). The amount of rosemary leaf extract in the supplement was not disclosed.
• Wound healing. It is unclear if topical rosemary cream is beneficial for wound healing. Details: A moderate-sized clinical trial among primiparous adults with medio-lateral episiotomy shows that applying a cream containing rosemary extract to the wound twice daily for 10 days improves episiotomy wound healing and reduces redness and discharge when compared with placebo cream (112143). More evidence is needed to rate rosemary for these uses.

• Bladder cancer. Consuming tomatoes and tomato-based products does not appear to reduce the risk of bladder cancer. Details: Observational studies have found no association between tomato and tomato-based product intake and the risk of bladder cancer (2407).
• Breast cancer. Consuming tomatoes and tomato-based products does not appear to reduce the risk of breast cancer. Details: Observational studies have found no association between tomato or tomato-based product intake and risk of breast cancer (15747).
• Diabetes. Consuming tomatoes and tomato-based products does not appear to prevent the development of type 2 diabetes or improve glycemic control in patients with type 2 diabetes. Details: Observational studies have found that increasing intake of tomato or tomato-based products does not significantly decrease the risk of developing type 2 diabetes (14004,14361). Additionally, a small clinical study in non-smoking male patients with type 2 diabetes shows that consuming raw tomato 200 grams daily for 8 weeks does not improve plasma glucose levels when compared to baseline (102477). The validity of this finding is limited by the lack of comparator group.

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aging skin. It is unclear if tomato improves skin appearance. Details: A small study of females aged 35-55 shows that taking a certain tomato pulp product (Lumenato, Lycored) 1 capsule daily for 12 weeks improves patient reported skin appearance scores when compared to baseline (110523). The interpretation of this result is limited by the lack of a placebo group.
• Benign prostatic hyperplasia (BPH). Oral tomato powder has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in patients with BPH shows that taking 5 grams of a whole tomato food supplement consisting of tomato powder and polyphenols extracted from olives daily for 2 months improves quality of life and reduces lower urinary tract symptoms including urinary frequency, urinary urgency, and nocturia when compared to baseline. No improvements in these symptoms were reported with placebo (106656). It is unclear if these findings are due to tomato, olive polyphenols, or the combination.
• Cardiovascular disease (CVD). It is unclear if consuming tomato-based foods reduces the risk of cardiovascular events. Details: Observational research has found that increased consumption of tomato-based foods is associated with an insignificant trend towards a reduced risk of myocardial infarction, stroke, and other cardiovascular events (10418,102178).
• Cataracts. It is unclear if consuming tomatoes reduces the risk of cataracts. Details: Observational research has found that eating more than 3 servings of tomatoes each week may decrease the risk of developing cataracts (9439).
• Cervical cancer. It is unclear if consuming tomatoes reduces the risk of cervical cancer. Details: Observational research has found that increased tomato intake is associated with a decreased risk of cervical cancer (2407).
• Colorectal cancer. Research on the benefits of consuming tomatoes or tomato-based products for the prevention of colorectal cancer is conflicting and limited to observational studies only. Details: Some observational research has found that increasing tomato or tomato-based product intake is associated with a reduced risk of colorectal cancer (2404,2407). However, higher quality observational research has found that tomato-based product intake is not associated with risk of colorectal cancer (15747).
• Exercise-induced asthma. It is unclear if oral tomato extract is beneficial in patients with exercise-induced asthma. Details: A small clinical study in patients with exercise-induced asthma shows that taking a specific tomato extract (Lyc-O-Mato, LycoRed Ltd) 30 mg daily for 1 week seems to reduce exercise-induced asthma when compared with placebo. The tomato extract seems to prevent decreases in forced expiratory volume (FEV1) in response to exercise (7898).
• Gastric cancer. Research on the benefits of consuming tomatoes or tomato-based products for the prevention of gastric cancer is conflicting and limited to observational studies only. Details: Some observational studies have found that increasing tomato or tomato-based product intake is associated with a reduced risk of gastric cancer in some subgroups of patients (2407,15747,102480). However, other observational research has found that tomato-based product intake is not associated with risk of gastric cancer (15747). In 2005, the US Food and Drug Administration (FDA) approved a qualified health claim regarding tomatoes and gastric cancer risk. However, the FDA concludes that it is highly unlikely that tomatoes reduce the risk of gastric cancer (102375).
• Hyperlipidemia. Small clinical studies suggest that consuming tomato sauce or semi-dried tomatoes may modestly reduce low-density lipoprotein (LDL) cholesterol levels in patients with hyperlipidemia. Details: One small, open-label clinical trial in patients with hyperlipidemia shows that consuming a specific vine-ripened tomato sauce (OsteoCol, C.G. Food, SRL) 150 mL daily for 6 weeks reduces total cholesterol and LDL cholesterol levels when compared to baseline. Patients adherent to the tomato sauce regimen showed an 11 mg/dL and 12 mg/dL reduction in total and LDL cholesterol, respectively, while those consuming a sterol-enriched yogurt saw total and LDL cholesterol levels decrease by 18 mg/dL and 16 mg/dL, respectively. Patients with a baseline LDL cholesterol level of greater than 152 mg/dL saw the greatest benefit from this tomato sauce (106653). Another small clinical study in Japanese patients with borderline high cholesterol shows that taking 50 grams of a semi-dried tomato containing lycopene 22-27.8 mg daily for 12 weeks modestly reduces LDL cholesterol levels but does not affect high-density lipoprotein (HDL) cholesterol levels when compared with taking 50 grams of a tomato without lycopene (102180). This suggests that any benefit of tomato on blood lipid levels is likely due to its lycopene content.
• Hypertension. Small clinical studies and observational research suggest that oral tomato extract or dietary tomato consumption may modestly reduce blood pressure in patients with hypertension. Details: Several small clinical trials in patients with hypertension show that taking a specific tomato extract product (Lyc-O-Mato, LycoRed, Ltd.), providing lycopene 15-30 mg daily, for 6-8 weeks, reduces systolic blood pressure by around 7-13 mmHg and diastolic blood pressure by around 4-6 mmHg when compared to baseline (14287,60415,102182). The validity of these findings is limited by the lack of a comparator group. Additionally, a large observational study, conducted over 3 years, suggests that moderate consumption of tomato-based products (i.e., 44-82 grams daily) is associated with marginally lower blood pressure when compared with higher and lower consumption in older adults with grade 1 hypertension. However, this association is not seen in patients with grade 2 or 3 hypertension (113145). Interpretation of these results is limited by self-reported data and lack of generalizability outside of confounders relating to a Mediterranean lifestyle. Evidence on the use of tomato in patients with pre-hypertension is mixed. One small clinical study in patients with pre-hypertension shows that taking a specific tomato extract (Fruitflow, Provexis Plc, UK.) 150 mg as a single dose seems to modestly reduce blood pressure over a 24-hour period when compared with placebo (102478). This study is limited by its small size and short duration. Another small clinical study in pre-hypertensive patients shows that taking a specific tomato extract (Lyc-o-Mato, LycoRed Ltd) containing lycopene 15 mg daily for 8 weeks does not reduce blood pressure when compared with placebo (42079). The impact of dietary tomato consumption on preventing hypertension has also been evaluated. A large prospective observational study in Chinese adults without a history of smoking or myocardial infarction suggests moderate dietary intake of tomatoes (i.e. up to 33.3 grams daily) is associated with a 49-58% reduction in the risk of developing new onset hypertension when compared with no consumption after about 6 years' follow up. However, the associated risk reduction was less with higher consumption (110525). These results may not apply to patients in countries where dietary trends are different, and the validity of these findings is limited by the potential for confounding. Another large observational study, conducted over 3 years in older adults at high cardiovascular risk, suggests that higher consumption (i.e., at least 1 large-sized tomato daily) is associated with reduced risk of hypertension by 36% when compared with moderate and lower consumption (113145). However, interpretation of these results is limited by self-reported data, and lack of generalizability outside of confounders relating to a Mediterranean lifestyle.
• Lung cancer. It is unclear if consuming tomatoes reduces the risk of lung cancer; the available research is conflicting. Details: Some observational studies have found an association between increased tomato and tomato-based product consumption and a reduced risk of lung cancer; however, many of these studies were not stratified based on the patient's smoking status. Higher quality, large-scale observational studies have not found any association between tomato product intake and lung cancer risk (15747).
• Muscle strength. It is unclear if consuming tomatoes improves muscle strength or attenuates declines in muscle strength. Details: A small observational study in Japanese adults 22-68 years of age found that more frequent tomato consumption (2 or more times weekly) is associated with an attenuated rate of handgrip strength decline over 3 years when compared with less frequent tomato consumption (102473).
• Ovarian cancer. Research on the benefits of consuming tomatoes or tomato-based products for the prevention of ovarian cancer is conflicting and limited to observational studies only. Details: Some observational research has found that increased tomato or tomato juice intake is not associated with risk of ovarian cancer; however, consuming tomato sauce two or more times weekly is associated with a decreased risk (2407). Other observational research has found that increased dietary intake of lycopene, particularly from tomato sauce, is associated with a reduced risk of ovarian cancer in premenopausal patients (10133). In 2005, the US Food and Drug Administration (FDA) approved a qualified health claim regarding tomato sauce and ovarian cancer risk. However, the FDA concludes that it is highly uncertain that tomato sauce reduces the risk of ovarian cancer (102375).
• Pancreatic cancer. Research on the benefits of consuming tomatoes or tomato-based products for the prevention of pancreatic cancer is conflicting and limited to observational studies only. Details: A large-scale observational study have found that that tomato or tomato-based product intake is not associated with a decreased risk of pancreatic cancer (15747). However, other observational studies have found that raw tomato intake, and high tomato intake in general, is associated with a reduced risk of pancreatic cancer (2407,15747,15750). In 2005, the US Food and Drug Administration (FDA) approved a qualified health claim regarding tomatoes and pancreatic cancer risk. However, the FDA concludes that it is highly unlikely that tomatoes reduce the risk of pancreatic cancer (102375).
• Prostate cancer. Consuming tomatoes or tomato-based products may slightly lower the risk of prostate cancer; however, observational research is mixed and high-quality clinical trials addressing tomato intake and prostate cancer risk are lacking. Details: Some observational studies have found that consuming tomato products, including tomatoes, tomato sauce, pizza, or tomato juice, one time or more per week, is associated with a modest reduction in the risk of prostate cancer (2406,7772,7895,12878,15747,102476). However, other observational research has found that tomato consumption is not associated with a reduced risk of prostate cancer (14125,15172,15747,92171). One small clinical study in patients with high-grade prostatic intraepithelial neoplasia shows that taking tomato extract capsules containing lycopene 30 mg daily for 6 months does not impact benign tissue endpoints when compared with placebo (102471). In 2005, the US Food and Drug Administration (FDA) approved a qualified health claim stating that one-half to one cup of tomatoes or tomato sauce weekly may reduce the risk of prostate cancer. However, the FDA concludes that there is little scientific evidence to support this claim (102375).
• Radiation dermatitis. It is unclear if drinking tomato juice is beneficial in patients with radiation dermatitis. Details: One small, uncontrolled clinical trial in patients undergoing radiotherapy for breast cancer shows that drinking tomato juice 160 mg daily for 6 months after radiotherapy improves the severity of dermatitis within 1 month of treatment when compared to baseline (106654). The lack of a comparator group limits the validity of these findings; it is unclear how tomato juice consumption compared with the natural resolution of radiation dermatitis. More evidence is needed to rate tomato for these uses.

LEVOTHYROXINE (Synthroid, others) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, celery seed might decrease the effects of levothyroxine.  Details Several cases of hypothyroidism with low T4 levels have been reported in people who were previously stabilized on levothyroxine and then started taking celery seed tablets. They presented with symptoms such as lethargy, bloating, and dry skin, and recovered when celery seed was stopped (10646). However, celery stem and leaf has been associated with case reports of hyperthyroidism in patients with no pre-existing thyroid disorders (102912,102914).

LITHIUM Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Theoretically, celery might reduce excretion and increase levels of lithium due to potential diuretic effects.  Details Celery is thought to have diuretic properties (4,6).

General ...Orally, beet seems to be well tolerated when used for medicinal purposes, short term.
Most Common Adverse Effects:
Orally: Red stools and red urine.
Serious Adverse Effects (Rare):
Orally: Hypocalcemia and kidney damage when ingested in large amounts.

Endocrine ...Theoretically, ingestion of large quantities of beets could lead to hypocalcemia because of the oxaluric acid content (18).

Gastrointestinal ...Orally, beet juice may cause red stools (94470,97726,100142,100145,105762). This red coloring of the stools is not harmful. Additionally, beet supplementation has been reported to cause black stools. In one case, a 79-year-old male on apixaban and clopidogrel presented with black stools, nausea, and vomiting after taking beet pills 2-3 days prior. The likelihood of upper gastrointestinal bleed was determined to be low based on factors such as normal vital signs and lack of severe anemia. The patient was diagnosed with beet-induced pseudo-hematochezia which was successfully treated with fluids and discontinuation of the beet supplement (113426).
Other less common gastrointestinal side effects include loose stools, constipation, and nausea (100149).

Genitourinary ...Orally, beet is known to produce red or pink urine (beeturia) in some people (32569,34134,94464,94470,97725,97726,100142,100145,100152,105762,113422). However, this red coloring of the urine is not harmful and dissipates after about 12 hours (113422).

Neurologic/CNS ...Orally, vivid dreams and worsening headaches have each occurred in one person in a clinical trial, although it is not clear if this is due to beet (97723).

Renal ...Theoretically, ingestion of large quantities of beets could lead to kidney damage due to its oxaluric acid content (18).

General ...Orally, carrot is well tolerated when consumed as a food. It also seems to be generally well-tolerated when consumed as a medicine. Some people are allergic to carrot; allergic symptoms include anaphylactic, cutaneous, respiratory, and gastrointestinal reactions such as hives, swelling of the larynx, asthma, or diarrhea (25820,93606,106560). In infants, excessive consumption of carrot products in nursing bottles has been reported to cause extensive caries in the primary teeth (25817).
Topically, carrot has been associated with a case of phytophotodermatitis (101716).

Dental ...Orally, feeding carrot juice to infants, with or without sugar- or acid-containing beverages, has been reported to damage teeth and cause dental caries (25817).

Dermatologic ...Orally, excessive consumption of carrots or carrot-containing products can cause yellowing of the skin, which results from increased beta-carotene levels in the blood (25817). Carrots may cause allergic reactions in some patients. Allergic responses to carrot-containing foods include skin reactions such as hives, erythema, swelling, and/or papules (25820,96306).

Gastrointestinal ...Orally, carrots may cause allergic reactions in some patients. Allergic responses to carrot-containing foods can include gastrointestinal symptoms, such as diarrhea (25820).

Immunologic ...Orally, carrots may cause allergic reactions in some patients (25820,96306,106560). Allergic responses to carrot-containing foods can include skin reactions such as hives, erythema, swelling, and/or papules (25820,96306). For one patient, treatment of skin lesions resolved after a month of oral antihistamines and topical steroids, and avoiding further contact with carrot (96306). Allergic responses to carrot-containing foods can also include gastrointestinal symptoms, such as diarrhea, and respiratory symptoms, such as swelling of the larynx or asthma (25820). In one case, a patient with a history of allergic rhinitis and asthma who had been successfully treated with subcutaneous immunotherapy and was tolerant of consumption of raw and cooked carrots developed rhinoconjunctivitis when handling carrots. Inhalation of dust particles and aerosols produced by food processing activities and containing allergens from the peel and pulp of carrots is thought to have sensitized the airway, producing a distinct form of respiratory food allergy in which there are typically no symptoms with ingestion (106560).
Topically, a female runner developed phytophotodermatitis, which was considered possibly associated with the inclusion of carrot in a sunscreen (Yes To Carrots Daily Facial Moisturizer with SPF 15; Yes to, Inc.) (101716).

Psychiatric ...Compulsive carrot eating is a rare condition in which the patient craves carrots. According to one case report, withdrawal symptoms include nervousness, cravings, insomnia, water brash, and irritability (25821).

General ...Orally, celery seems to be well tolerated.
Most Common Adverse Effects:
Orally: Photosensitivity. Oral allergy syndrome in sensitive individuals.
Topically: Photosensitivity. Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.

Dermatologic ...Due to its psoralen content, contact with or ingestion of celery and exposure to ultraviolet radiation may cause photodermatitis (4,34347,40968,40969,40986,41085,41087,41143,41146,41151). Acute symptoms include skin eruption with edema and erythema; the main chronic symptom is hyperpigmentation at the eruption site (41093).
Celery can also cause contact or atopic dermatitis (19,41118,41124) and urticaria pigmentosa (40908).

Endocrine ...Celery has been associated with hyperthyroidism in otherwise healthy adults. In one case report a 36-year-old female presented with weight loss, blurred vision, nausea, palpitations, sweating, exophthalmos, elevated serum T4 levels, and low thyroid stimulating hormone (TSH) levels after taking 8 grams of a powdered celery extract for 78 days (102912). In another case report, a 48-year-old male presented with weight loss, exophthalmos, sweating, elevated serum T4 levels, and low TSH levels after taking 4 grams of dried celery leaves for 45 days (102914). In both of these cases, symptoms resolved and thyroid function tests normalized after discontinuing celery and completing a course of methimazole.
In contrast, several cases of hypothyroidism with low T4 levels have been reported in people who were previously stabilized on levothyroxine and then started taking celery seed tablets. They presented with symptoms such as lethargy, bloating, and dry skin, and recovered when celery seed was stopped (10646).

Gastrointestinal ...Symptoms of celery allergy have included oral allergy syndrome, characterized by itching and burning in the mouth and throat (41159,40977), and laryngeal edema (40953).

Immunologic ...Raw celery, cooked celery, and celery juice can all cause allergic reactions (40908,40926,41118,41131,92852,92855). Symptoms of celery allergy include laryngeal edema, skin reactions, an urticaria-edema-anaphylactic shock syndrome, celery-dependent exercise-induced anaphylaxis, and anaphylactic shock (40953,41100,41102,41107,41115,41124,41129,41135,41137,92852)(92855). Additionally, in clinical research, itchy throat has been reported in individuals taking celery seed powder (112410).
There is a case report of anaphylactic shock involving hypotension, tachycardia, and tachypnea in a patient who had ingested raw celery 15 minutes prior to symptom onset. The patient was treated with epinephrine, dexamethasone, and antazoline (92855). Another case report describes a patient with positive skin prick tests to celery, pollens including birch, chrysanthemum, mugwort, and ragweed, and to dust mites. When celery was consumed 30 minutes prior to exercise, the patient had an anaphylactic reaction that required treatment with intravenous pheniramine and corticosteroid, as well as nebulized albuterol (92852). Another patient with a history of anaphylactic reactions to undeclared celery in restaurant meals was able to undergo desensitization with gradually increasing oral doses of celery juice over several months, and then chronic daily ingestion of the juice to maintain hyposensitization (40908).

General ...A high-quality assessment of the adverse effects of lovage has not been conducted. However, long-term oral use of lovage may result in an increased risk of phototoxic reactions, including photosensitivity (2,5,6,8,11,12). Topical exposure may also result in photosensitivity or contact dermatitis (60058,94098).

Dermatologic ...Orally, long-term use of lovage may result in an increased risk of phototoxic reactions, including photosensitivity (2,5,6,8,11,12). Avoid excessive exposure to the sun or UV light if using lovage (2,12). A case of contact dermatitis has been reported in a 31-year-old female who applied undiluted lovage essential oil to the skin for 2 weeks. The skin healed after receiving topical and systemic steroids (94098). A case of photosensitivity has also been reported secondary to harvesting lovage (60058).

General ...Orally, rosemary seems to be well tolerated when used in appropriate medicinal amounts. Undiluted rosemary oil or very large quantities of rosemary leaf should not be consumed. Topically and as aromatherapy, rosemary seems to be well tolerated.

Dermatologic ...Topically, rosemary use can lead to photosensitivity, erythema, dermatitis, and cheilitis in hypersensitive individuals (4,6).

Immunologic ...Topically, allergic reactions can occur. When used in the mouth, lip and gum edema have occurred (101173). When used on the skin, allergic contact dermatitis has occurred, likely due to the constituent carnosol (71715,71924,71926).
Rosemary might also cause occupational asthma. A case of occupational asthma caused by several aromatic herbs including thyme, rosemary, bay leaf, and garlic has been reported. The diagnosis was confirmed by inhalation challenges. Although all of the herbs caused immediate skin reactivity, a radioallergosorbent test (RAST) showed that garlic was the most potent allergen by weight, with rosemary and the other herbs showing less reactivity (783).

Neurologic/CNS ...Orally, the undiluted oil, as well as the camphor constituent of rosemary, might cause seizures (4,5,6,12868).
