• Intestinal parasite infection. Although there is interest in using oral asparagus for intestinal parasite infection, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Hypertension. Oral asparagus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with hypertension shows that taking a specific combination product (Asparagus-P, Grunwalder) containing asparagus root 6 grams and parsley leaf 6 grams daily for 6 weeks does not affect ambulatory blood pressure when compared with baseline (94940).
• Kidney stones (nephrolithiasis). Although there is interest in using oral asparagus for kidney stones, there is insufficient reliable information about the clinical effects of asparagus for this condition.
• Obesity. Oral asparagus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Observational research in overweight adults shows that taking psyllium 2-3 tablespoons each morning with 1.5 liters of elderflower juice, plus tablets providing asparagus powder 2.7 grams, elderberry powder 225 mg, and elderflower extract 600 mg daily for 2 weeks, and replacing each meal on days 5-12 with 200 mL of elderberry and elderflower juice, is associated with an average 3.2 kg weight loss and a modest reduction in blood pressure when compared with baseline (94939). It is not known if these effects are due to asparagus, other ingredients, the combination, or fasting from regular food for 8 days. Furthermore, the validity of these findings is limited by the lack of a comparator group.

• Anxiety. Although there is interest in using oral Asparagus racemosus for anxiety, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition.
• Athletic performance. It is unclear if oral Asparagus racemosus is beneficial for improving athletic performance. Details: In recreationally trained males, taking Asparagus racemosus 500 mg daily for 8 weeks during bench press training increases the number of repetitions before exhaustion, and allows a greater increase in training loads, when compared with placebo (106413).
• Bronchitis. Although there is interest in using oral Asparagus racemosus for bronchitis, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition.

• HIV/AIDS. Although there is interest in using oral Asparagus racemosus for HIV/AIDS, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition.
• Lactation. Oral Asparagus racemosus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In mothers who have to supplement their breast milk or who have infants with below normal weight gain, taking an herbal mixture containing Asparagus racemosus as 2 teaspoons twice daily for 4 weeks does not increase breast milk production, infant weight gain velocity, or prolactin levels (32588). Per 100 grams, the herbal mixture contained Asparagus racemosus 15 grams, dill 1 gram, morning glory 1 gram, licorice 2.5 grams, cumin 0.5 grams, and panchatrinamol 1 gram. Another small clinical study in postpartum mothers in India shows that consuming Asparagus racemosus in the form of 1 daily granola bar that contains Asparagus racemosus and other ingredients (Shavari Bar, Act Life Sciences Ltd.) for 4 days starting the day after delivery increases breast milk volume by about 15 mL and shortens the time to breast fullness when compared with placebo (111721). However, it is unclear whether any improvement is clinically significant, especially in the longer term. Additionally, the dose of Asparagus racemosus was not specified which limits the interpretation of these results.
• Muscle strength. It is unclear if oral Asparagus racemosus is beneficial for improving muscle strength. Details: A very small clinical study in physically active postmenopausal patients shows that taking Asparagus racemosus 1000 mg daily for 6 weeks improves hand grip strength, but not knee extensor strength, when compared with placebo (110736).
• Sexual desire. Although there is interest in using oral Asparagus racemosus for sexual desire, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this purpose.
• Tuberculosis. Although there is interest in using oral Asparagus racemosus for tuberculosis, there is insufficient reliable information about the clinical effects of Asparagus racemosus for this condition. More evidence is needed to rate Asparagus racemosus for these uses.

• Hypercholesterolemia. Consuming a diet rich in avocados seems to improve serum lipid levels. Details: Consuming a diet rich in avocados (e.g., 0.5-2 avocados daily or a diet in which avocados account for 75% of total daily fat intake) for 1-4 weeks seems to lower total serum cholesterol, low-density lipoprotein (LDL) cholesterol, and apolipoprotein B. It may also increase high-density lipoprotein (HDL) serum cholesterol levels (668,669,670,671,33256). In contrast, a meta-analysis of 8 clinical studies in adults with various metabolic conditions shows that consuming avocado 99-330 grams daily for 3-24 weeks reduces total cholesterol by 5 mg/dL but does not reduce LDL cholesterol or triglycerides or increase HDL cholesterol when compared with diets containing no or low amounts of avocado. However, subgroup analysis in patients with hypercholesterolemia suggests that consuming avocado reduces LDL cholesterol by 9 mg/dL and total cholesterol by 7.5 mg/dL (112435).

• Aging skin. It is unclear if consuming avocado is beneficial for aging skin. Details: A small study in females with overweight or obesity shows that consuming one avocado daily for 8 weeks improves forehead skin firmness, but not elasticity or tiring, when compared with no avocado consumption. No improvements in under eye skin firmness, elasticity, or tiring were observed (108010).
• Cardiovascular disease (CVD). It is unclear if consuming avocado is beneficial for reducing the risk of CVD. Details: Observational research has found that consumption of at least one avocado weekly is associated with a 16% lower risk of CVD and a 21% lower risk of coronary heart disease (CHD) when compared with no avocado consumption. However, there was no association between avocado consumption and the risk of stroke. Additionally, replacement of half a serving daily of certain fat-containing foods (i.e., margarine, butter, egg, yogurt, cheese, processed meats) with an equivalent amount of avocado is associated with a 16% to 22% lower risk of CVD (108007).
• Cognitive function. It is unclear if consuming avocados is beneficial for improving cognitive function. Details: Preliminary clinical research in adults with overweight or obesity shows that consuming one avocado daily as part of a test meal for 12 weeks improves attentional inhibition, but not response inhibition, during cognitive testing when compared with baseline. Improvements on these tests were not reported in patients receiving an isocaloric control meal (103895). A cross-sectional study in older adults has also found that avocado consumption is associated with improvements in memory performance on immediate learning and delayed recall tests as well as global cognitive scores when compared with no avocado consumption (108013).
• Metabolic syndrome. It is unclear if consuming avocados is beneficial for metabolic syndrome. Details: A very large clinical study in adults with an elevated waist circumference shows that consuming a large avocado daily for 6 months reduces total cholesterol by 3 mg/dL and low-density lipoprotein cholesterol by 2.5 mg/dL but does not change any other measures of metabolic syndrome including visceral adiposity, waist circumference, body weight, body mass index (BMI), systolic and diastolic blood pressure, glucose, insulin, triglycerides, very low-density lipoprotein cholesterol, or high-density lipoprotein cholesterol when compared with a standard diet without avocados (112436). Additionally, a small clinical study in adults with overweight, obesity, and insulin resistance shows that consuming an avocado daily for 12 weeks does not change BMI, body composition, blood pressure, fasting glycemic indices, glucose levels, plasma lipid profiles, insulin sensitivity, or markers of inflammation or endothelial function when compared with control (112438).
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if consuming avocados is beneficial for NAFLD. Details: A secondary analysis of a previous clinical study in adults with overweight and obesity shows that consuming 14 avocados per week per family for 6 months does not improve NAFLD fibrosis score or biomarkers of hepatic function including alanine transaminase (ALT), aspartate transaminase (AST), gamma glutamyl-transferase (GGT), or high-sensitivity c-reactive protein (hsCRP) when compared with low avocado consumption, defined as 3 avocados per week per family (112437).
• Obesity. It is unclear if consuming avocados is beneficial for weight loss or prevention of weight gain. Details: A meta-analysis of clinical trials and a very large clinical study in adults with overweight, obesity, and elevated waist circumference shows that consuming one avocado daily or 136-200 grams daily for 6 weeks to 6 months does not reduce body weight, body mass index (BMI), percent fat mass, or visceral adipose tissue when compared with control (112433,112436). However, a small study in adults with overweight or obesity shows that consuming one avocado daily for 12 weeks changes abdominal adiposity distribution among females, but not males, when compared with no avocado consumption. No significant effects were observed for glucose or insulin outcomes (108008). Preliminary clinical research in adults with overweight or obesity shows that eating half of an avocado with lunch increases satisfaction by 23% to 26% and decreases desire to eat by 28% to 40% when compared with a control lunch with no avocado (93109). A large observational study in the same population has found that habitual consumption of avocado at an average intake of 32 grams or more daily is not associated with reductions in body weight or body mass index (BMI) over 5 years when compared with no avocado consumption. Additionally, this study suggests that while habitual avocado consumption in patients with normal weight may slightly attenuate increases in body weight and BMI, it does not seem to reduce the odds of these patients becoming overweight or developing obesity over time when compared with no avocado intake (100936).
• Psoriasis. Topical avocado has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with psoriasis shows that applying a specific cream containing avocado oil and vitamin B12 (Regividerm, Regeneratio Pharma AG) 0.7 mg/gram to the affected area for 12 weeks reduces symptoms to a similar extent when compared with calcipotriol ointment (Psorcutan). The avocado combination cream also causes significantly less irritation than calcipotriol (14909). It is unclear if these effects are due to avocado, vitamin B12, or the combination. More evidence is needed to rate avocado for these uses.

• Bladder cancer. It is unclear if consumption of broccoli reduces the risk of developing bladder cancer. Details: Epidemiological research suggests that eating about 1.75 cups daily of cruciferous vegetables, such as broccoli or cabbage, is associated with a 30% reduced risk of developing bladder cancer (14864).
• Breast cancer. It is unclear if consumption of broccoli reduces the risk of developing breast cancer. Details: Epidemiological research suggests that consumption of broccoli is associated with a modestly reduced risk of developing breast cancer in premenopausal adults. However, broccoli consumption does not seem to be associated with breast cancer risk in postmenopausal adults (14146).
• Fibromyalgia. Broccoli has only been evaluated in combination with ascorbigen; its effect when used alone is unclear. Details: A small clinical study in females with fibromyalgia shows that taking one capsule containing ascorbigen 100 mg and broccoli powder 400 mg once daily for one month improves pain by 18% and reduces physical impairment by 20% when compared to baseline (19605). It is unclear if this effect is due to broccoli, ascorbigen, or the combination. The validity of these findings is limited by the lack of a comparator group.
• Gastric cancer. It is unclear if consumption of broccoli reduces the risk of developing gastric cancer. Details: A small epidemiological study suggests that higher consumption of broccoli is associated with a reduced risk of developing gastric cancer when compared with lower consumption (14148).
• Helicobacter pylori. It is unclear if consumption of broccoli is beneficial for treating Helicobacter pylori infection. Details: A moderate-sized clinical study in adults with Helicobacter pylori infection shows that taking broccoli seed extract 200 mg, containing 16% glucosinolates, daily before bedtime for 2 months does not improve Helicobacter pylori eradication rate when compared with placebo (112445,112446).
• Hypercholesterolemia. Broccoli has only been evaluated in combination with cabbage; its effect when used alone is unclear. Details: A small clinical study in patients with mild to moderate hypercholesterolemia shows that consuming 160 grams of a beverage containing broccoli, cabbage, and fruit twice daily for 12 weeks reduces levels of low-density lipoprotein (LDL) cholesterol by 8.5% when compared to baseline. It is unclear if the improvement from baseline differed when compared with those consuming a similar beverage without broccoli and cabbage (19607). It is unclear if this effect is due to broccoli, other ingredients, or the combination.
• Hypertension. It is unclear if consumption of broccoli can prevent hypertension in healthy adults. Details: A meta-analysis of 3 prospective cohort studies in healthy adults suggests that eating 100 grams of broccoli daily is associated with a 12% reduced risk of hypertension. However, 2 other studies in the meta-analysis suggest that broccoli, consumed as part of a larger group of cruciferous vegetables, is associated with an 11% increased risk of hypertension per 100 grams eaten daily (112087).
• Prostate cancer. It is unclear if consumption of broccoli reduces the risk of developing prostate cancer; the available research is conflicting. In patients with prostate cancer, broccoli has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some epidemiological research suggests that consumption of Brassica vegetables, such as broccoli, Brussels sprouts, cauliflower, and cabbage, is associated with a reduced risk of developing prostate cancer (14145). However, other epidemiological research has found no association (14147,15172). Clinical research in adults with prostate cancer shows that taking a whole food formulation containing broccoli powder 100 mg, turmeric powder 100 mg, pomegranate whole fruit powder 100 mg, and green tea extract 20 mg three times daily for 6 months prevents an increase in prostate specific antigen (PSA) levels. Mean PSA levels increased by 15% in the whole food formulation group, compared with 79% in the placebo group. Also, 46% of those taking the whole food formulation showed final PSA levels that were the same or lower than initial PSA levels, compared with 14% of those in the placebo group (89730). However, it is not yet known whether the whole food formulation reduces the risk of prostate cancer progression or recurrence. It is unclear if these effects are due to broccoli, other ingredients, or the combination. More evidence is needed to rate broccoli for these uses.

• Benign prostatic hyperplasia (BPH). Population research has found that higher intake of Brussels sprout is not associated with significantly reduced risk of BPH (26190).
• Bladder cancer. Epidemiologic research has found that eating about 1 cup daily of cruciferous vegetables, such as cabbage, Brussels sprout, cauliflower, broccoli, kale, or collards, is associated with a 30% lower risk of developing bladder cancer in adults (14864). Other population research has found that higher intake of cruciferous vegetables, such as cauliflower, Brussels sprout, cabbage, broccoli, and kale, is associated with a 51% reduction in the risk of developing bladder cancer in males. However, higher intake of Brussels sprout alone does not seem to be associated with a reduced risk of bladder cancer (26184).
• Breast cancer. Some population research has found that higher intake of cruciferous vegetables, including broccoli, Brussels sprout, cabbage, cauliflower, collards, and kale, is associated with a slight increase in the risk of breast cancer in premenopausal adults, while higher intake appears to be associated with a slight but statistically insignificant decrease in the risk in postmenopausal adults (26188). However, other population research has found that higher intake of Brussels sprout alone is not associated with a reduced risk of breast cancer (26189). Cruciferous vegetables might increase urinary levels of 2-hydroxyestrone, and its ratio to 16-alpha-hydroxyestrone, which could reduce the risk of breast cancer. However, research in pre-menopausal adults shows that taking a dried Brussels sprout and kale supplement, 3.3 grams daily for 8 weeks, or increasing dietary intake of Brussels sprout or broccoli by one 40-gram serving daily, does not increase urinary levels of 2-hydroxyestrone, or its ratio to 16-alpha-hydroxyestrone, when compared with placebo (112086).
• Diabetes. Population research has found that higher intake of cruciferous vegetables, including broccoli, cabbage, cauliflower, and Brussels sprout, is not associated with a reduced risk of developing type 2 diabetes (26187). A meta-analysis of 23 studies shows that the highest levels of combined vegetable and fruit intake are associated with a 7% reduction in the risk of developing type 2 diabetes, when compared with the lowest intakes, but higher intake of Brussels sprout alone is associated with a 7% increase in the risk (112088).
• Hypertension. A meta-analysis of 18 studies in healthy adults shows that the highest levels of combined vegetable and fruit intake are associated with a 9% to 11% reduction in the risk of developing hypertension, when compared with the lowest intakes, but higher intake of Brussels sprout alone is associated with a 25% increase in the risk (112087).
• Lung cancer. Population research has found that people who consume Brussels sprout and broccoli at least once weekly have a 22% lower risk of developing lung cancer when compared with those who consume these vegetables less than once monthly (26192).
• Non-Hodgkin lymphoma. Population research has found that females who consume at least half a serving of Brussels sprout or other cruciferous vegetables daily have a lower risk of developing non-Hodgkin lymphoma, particularly the follicular lymphoma subtype, when compared to those who eat these vegetables less often. However, eating Brussels sprout and other cruciferous vegetables does not appear to be associated with a reduced risk of non-Hodgkin lymphoma in males (26186).
• Pancreatic cancer. Population research has found that consuming higher amounts of Brussels sprout is not associated with a reduced risk of pancreatic cancer (26181).
• Prostate cancer. Population research has found that people who consume higher amounts of Brussels sprout and other cruciferous vegetables have a lower risk of developing prostate cancer (25420,25421).
• Stroke. Population research has found that higher intake of Brussels sprout and other cruciferous vegetables is associated with a 32% reduction in the risk of ischemic stroke (7394). More evidence is needed to rate Brussels sprout for these uses.

• Breast engorgement. Most research shows that applying cabbage leaves to engorged breasts reduces pain and hardness to the same degree as cold compresses in lactating females with breast engorgement. Details: Several small clinical studies suggest that applying whole cabbage leaves to the engorged breasts of lactating females produces subjective relief similar to the use of chilled gel-packs (6781,6784,93677). Both chilled and room temperature cabbage leaves seem to provide the same relief (6782). Another small clinical study shows that whole cabbage leaves also seem to improve breast pain and hardness when compared with general nursing care (93673). When compared with hot and cold compresses, one small clinical study found that using chilled cabbage leaves reduces postnatal breast engorgement to a similar degree, but is not as effective for reducing pain (101966). The preparation of cabbage leaves for this purpose sometimes includes stripping out the large vein of the cabbage leaf and cutting a hole for the nipple. Cabbage leaves are rinsed and chilled. The chilled cabbage leaf is worn inside the bra or as a compress under a cool towel. This procedure is typically repeated 1-4 times daily for 1-3 days (6781,6784,93673,93677,101966). A cabbage leaf extract applied as a cream has also been tried. The cabbage leaf extract cream seems to provide subjective relief when compared to baseline, but it does not provide superior relief when compared with a placebo cream (6783).

• Colorectal cancer. It is unclear if consuming cabbage is effective for the prevention of colorectal cancer. Details: Observational research has found that consuming large amounts of cabbage and other Brassica vegetables such as kale, broccoli, and cauliflower is associated with a lower risk of developing colorectal cancer (6792).
• Gastric cancer. It is unclear if consuming cabbage is effective for the prevention of gastric cancer. Details: Observational research has found that consuming large amounts of cabbage and other Brassica vegetables such as kale, broccoli, and cauliflower is associated with a lower risk of developing stomach cancer (6792).
• Gastritis. Although there has been interest in using oral cabbage for gastritis, there is insufficient reliable information about the clinical effects of cabbage for this purpose.
• Hyperlipidemia. It is unclear if oral cabbage is beneficial in patients with hyperlipidemia. Details: A small clinical study in Japanese adults with hyperlipidemia shows that adding broccoli and cabbage to a beverage consisting of fruits and vegetables for 3-9 weeks reduces low-density lipoprotein (LDL) cholesterol levels by 8.5% when compared to baseline. The reduction in LDL cholesterol was significant when compared with the same beverage without broccoli and cabbage added (25423).
• Knee pain. It is unclear if topical cabbage is beneficial in patients with knee pain. Details: A small clinical study in males with an acute mild to moderate traumatic knee ligament injury shows that use of crushed fresh cabbage leaf and cooling dressing wraps improves recovery over the first 24 hours of use by a moderate amount when compared with the cooling dressing alone. Normal fluid release occurred in 67% to 80% of patients using crushed cabbage leaf compared with 47% to 50% of those given the cooling dressing alone (101969).
• Lung cancer. It is unclear if consuming cabbage is effective for the prevention of lung cancer. Details: Observational research has found that consuming large amounts of cabbage and other Brassica vegetables such as kale, broccoli, and cauliflower is associated with a lower risk of developing lung cancer (6792).
• Osteoarthritis. Small clinical studies suggest that topical cabbage leaf modestly improves pain and other symptoms in patients with osteoarthritis of the knee. Details: A small clinical study in patients with osteoarthritis of the knee shows that applying cabbage leaf wraps to the knees for at least 2 hours daily for 4 weeks decreases pain by around 12 points on a 100 mm visual analog scale when compared with usual care. The analgesic effect of cabbage leaf wraps in these patients appears to be similar to treatment with topical gel containing the nonsteroidal anti-inflammatory drug diclofenac 10 mg/gram (93671). Another small, open-label clinical study in patients with moderate to severe osteoarthritis of the knee shows that applying cabbage leaf wraps to the knees for 1 hour daily for 4 weeks reduces knee pain and improves symptom severity when compared with diclofenac gel applied four times daily. Improvements in pain and overall symptoms were similar between cabbage leaf and the use of cooling gel pads (110558). The validity of these findings is limited by a lack of blinding.
• Pancreatic cancer. It is unclear if consuming cabbage is effective for the prevention of pancreatic cancer. Details: Observational research in elderly and middle-aged individuals has found that consuming one or more servings of cabbage per week is associated with a 38% lower risk of developing pancreatic cancer when compared with those who do not eat cabbage (25422).
• Peptic ulcers. Although there has been interest in using oral cabbage for peptic ulcers, there is insufficient reliable information about the clinical effects of cabbage for this purpose.

• 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).

• Cisplatin-induced neurotoxicity. Intravenous glutathione seems to reduce neurotoxicity from cisplatin. Details: Clinical studies in cancer patients receiving cisplatin shows that administering glutathione 1.5 grams/m2 by intravenous injection over 15 minutes seems to help prevent neurotoxicity and other toxicities from cisplatin when compared with control. Glutathione may also increase the highest dose of cisplatin that patients are able to tolerate (5373,5374,5377,5378,5380). In one study, this same dose of intravenous glutathione was administered, along with intramuscular glutathione 600 mg on days 2-5 (5374).

• Aging. Although there is interest in using oral glutathione for aging, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Alcohol use disorder. Although there is interest in using oral glutathione for alcohol use disorder, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Athletic performance. Oral glutathione has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in young, resistance-trained males shows that taking glutathione (Setria, Kyowa Hakko Bio) 200 mg in combination with L-citrulline 2 grams daily for 8 weeks in conjunction with resistance training has no effect on muscle strength, as measured by leg and bench presses, when compared with L-citrulline alone or with placebo (97394). The trial shows the increase in lean body mass with training to be significantly higher with glutathione and L-citrulline compared with placebo at 4 weeks. However, by 8 weeks of training lean body mass is not different between supplementation and placebo. An additional small, cross-over trial in young, endurance-trained males shows that taking glutathione 200 mg in combination with L-citrulline 2 grams (Setria Performance Blend, Kyowa Hakko Bio) daily for 8 days does not improve high speed running performance, as measured by time to exhaustion, when compared with placebo (112285).
• Angioplasty. It is unclear if intravenous glutathione is beneficial in patients recovering from angioplasty following myocardial infarction. Details: A small clinical trial in Italian adults undergoing primary percutaneous coronary intervention (PCI) for recent ST-elevation myocardial infarction (STEMI) shows that intravenous infusion of glutathione sodium salt 2500 mg/25 mL over 10 minutes before angioplasty and at 24, 48 and 72 hours after angioplasty reduces length of hospital stay by around 2 days; reduces markers of oxidative stress, inflammation, and cardiomyocyte damage; and improves measures of left ventricular function at 6-month's follow-up when compared with placebo (111417,111418).
• Alzheimer disease. Although there is interest in using oral glutathione for Alzheimer disease, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Cardiovascular disease (CVD). Although there is interest in using oral glutathione for preventing CVD, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Cataracts. Although there is interest in using oral glutathione for cataracts, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Chronic fatigue syndrome (CFS). Although there is interest in using oral glutathione for CFS, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Cirrhosis. It is unclear if oral glutathione is beneficial for improving cirrhosis severity. Details: A small clinical study in patients with cirrhosis shows that taking glutathione 500 mg daily with or without vitamin B6 50 mg daily for 12 weeks does not affect disease severity or reduce oxidative stress when compared with placebo (104392). These findings are limited because the study might not have been powered to detect a difference between groups, as 21 of the 61 participants were lost to follow-up.
• Cognitive function. Oral glutathione has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small cross-over trial in healthy adults shows that taking a product providing 20 mg/day of glutathione as part of a combination product containing probiotics (L. helveticus, Lactiplantibacillus plantarum, Bifidobacterium longum), inulin, zinc, potassium, magnesium and lactoferrin (Puraflor, GSK Consumer Healthcare) for 4 weeks does not affect cognitive performance during acute stress when compared with placebo (110923).
• Contrast induced nephropathy. It is unclear if intravenous glutathione is beneficial for preventing contrast induced nephropathy. Details: A small, non-blinded clinical study in patients aged 65 or older with diabetes undergoing percutaneous coronary intervention (PCI) shows that intravenous reduced glutathione 180 mg daily for 4 days, starting 6 hours prior to PCI, in conjunction with saline hydration, does not reduce the rate of contrast induced nephropathy when compared with saline hydration alone. Saline hydration was administered at a rate of 1 mL/kg/hr, starting 6 hours prior to PCI and continuing for 12 hours after PCI (107477). However, this study may have been inadequately powered to detect a difference between groups.
• Cystic fibrosis. It is unclear if oral glutathione is beneficial in children with this condition. Details: A small clinical study in children ages 2-10 years old with cystic fibrosis shows that taking glutathione powder 65 mg/kg daily in 3 divided doses for 6 months does not impact weight or inflammatory biomarkers when compared with placebo (104391).
• Glaucoma. Although there is interest in using oral glutathione for glaucoma, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Idiopathic interstitial pneumonia. Although there is interest in using inhaled glutathione for idiopathic pulmonary fibrosis, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral glutathione is beneficial in patients with NAFLD. Details: Preliminary clinical research shows that taking glutathione 300 mg daily for 4 months reduces alanine aminotransferase (ALT) levels by around 13% and triglyceride levels by around 16%, but has no impact on aspartate aminotransferase (AST) levels or liver stiffness, when compared with baseline in patients with NAFLD (97397). The validity of these findings is limited by the lack of a comparator group.
• Osteoarthritis. Although there is interest in using oral glutathione for osteoarthritis, there is insufficient reliable information about the clinical effects of glutathione for this condition.
• Parkinson disease. It is unclear if intranasal glutathione is beneficial for improving Parkinson disease symptoms. Details: A small clinical study in patients with Parkinson disease shows that taking glutathione intranasally 100-200 mg three times daily for 3 months has no effect on symptoms when compared with placebo (97398). More evidence is needed to rate glutathione for these uses.

• Cognitive function. It is unclear if consuming spinach is beneficial for cognitive function. Details: Preliminary clinical research in healthy adults shows that consuming spinach 200 grams with lunch does not improve attention or memory after 150 minutes when compared with a rice milk control (96852).
• Muscle strength. It is unclear if oral spinach is beneficial for muscle strength. Details: A small, preliminary clinical study in healthy adults over 50 years of age shows that taking an aqueous spinach extract, 1 gram orally twice daily, in conjunction with a moderate-intensity exercise program, 3 sessions per week of 1 hour each for 12 weeks, improves several measures of muscle strength and quality in both sexes, and increases lower leg muscle mass in males, when compared with placebo (109546).
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral spinach can reduce the risk of developing NAFLD. Details: A large observational study has found that raw, but not boiled, spinach consumption is inversely associated with the risk of developing NAFLD (106566).
• Obesity. It is unclear if consuming spinach is beneficial for weight loss. Details: Preliminary clinical research in overweight or obese middle-aged and older females shows that taking a specific spinach product (Appethyl, Greenleaf Medical AB) 5 grams daily before breakfast for 12 weeks increases weight loss by an additional 1.5 kg when compared with placebo. However, fat loss, waist circumference, and blood lipids are not improved when compared with placebo (96856,96857).
• Polycystic ovary syndrome (PCOS). It is unclear if oral spinach-derived thylakoids are beneficial for PCOS. Details: A small clinical study in premenopausal adults with PCOS and obesity shows that adding 5 grams orally daily of spinach-derived thylakoids to a low-calorie diet for 12 weeks reduces weight and body mass index (BMI) by 8%, compared with 4% with placebo and the low-calorie diet. Insulin resistance is also improved among those receiving spinach extract. These changes are unlikely to be clinically significant (106568). More evidence is needed to rate spinach for these uses.

General ...Asparagus is usually well tolerated when used in food amounts. Information on its use in medicinal amounts is limited.
Most Common Adverse Effects:
Orally: Urine odor.
Serious Adverse Effects (Rare):
All routes of administration: Allergic reactions.

Gastrointestinal ...Orally, a specific combination product (Asparagus-P, Grunwalder) containing asparagus root 6 grams and parsley leaf 6 grams caused constipation, abdominal distension and pain, nausea, dry mouth, and gallbladder complaints in up to 50% of the study population in one clinical trial (94940). It is not clear if these effects were due to asparagus root, parsley, or the combination.

Genitourinary ...Orally, asparagus can cause a strong urine odor in some people. It is not produced in all individuals, nor are all individuals able to smell the odor (32581,32583,32584,94942).
Orally, a specific combination product (Asparagus-P, Grunwalder) containing asparagus root 6 grams and parsley leaf 6 grams caused dysuria in approximately 2.5% of patients in one clinical trial (94940). It is not clear if this effect was due to asparagus root, parsley, or the combination.

Immunologic ...Orally and topically, asparagus can cause allergic reactions. They can occur in individuals sensitive to other members of the Liliaceae family, including onions, garlic, leeks, and chives (15557,15561,15562). Ingestion of fresh or canned asparagus can cause itchy eyes, runny nose, coughing, urticaria, dysphagia, dyspnea, and anaphylaxis in sensitized people (15561,15562,15564,32536,32594). There are also reports of fixed food eruptions, with lesions occurring at the same skin locations after ingesting asparagus on three separate occasions (15557,94941). Topically, exposure to asparagus during harvesting, processing, or cooking has caused contact dermatitis, urticaria, asthma, rhinitis, and conjunctivitis (15557,15561,15562,15564,32587,94943).

Musculoskeletal ...Orally, a specific combination product (Asparagus- P, Grunwalder) containing asparagus root 6 grams and parsley leaf 6 grams caused gout in approximately 2% of patients in one clinical trial (94940). It is not clear if this effect was due to asparagus root, parsley, or the combination.

Renal ...Orally, a specific combination product (Asparagus-P, Grunwalder) containing asparagus root 6 grams and parsley leaf 6 grams caused kidney pain and peripheral edema in approximately 15% of patients in one clinical trial (94940). It is not clear if these effects were due to asparagus root, parsley, or the combination.

General ...Orally, avocado has been generally well tolerated in clinical research.
Most Common Adverse Effects:
Topically: A cream containing avocado oil in combination with vitamin B12 can cause itching.
Serious Adverse Effects (Rare):
Orally: Avocado may lead to allergic cross-sensitivity in latex sensitive patients. While rare, avocado can cause acute food protein-induced enterocolitis syndrome (FPIES), a food hypersensitivity reaction characterized by excessive vomiting and diarrhea.

Dermatologic ...Topically, a cream containing avocado oil in combination with vitamin B12 can cause itching when applied initially, but itching appears to diminish with continued use (14909). Orally, avocado may cause skin rash (112436).

Gastrointestinal ...Orally, avocado can cause acute food protein-induced enterocolitis syndrome (FPIES). This is a rare, delayed, non-IgE-mediated gastrointestinal food hypersensitivity reaction most often reported in infants and young children. Symptoms of FPIES include excessive vomiting within 1-4 hours of avocado consumption and diarrhea. Treatment is generally supportive in nature, including oral or intravenous rehydration, along with avoidance of avocado (100938). There have also been reports of gastrointestinal upset including gas, bloating, and diarrhea due to daily avocado consumption, though it is possible that these symptoms were due to E. coli infection (112436).

Immunologic ...Orally, avocado may lead to type I hypersensitivity reactions in people who are allergic to latex (6197,7853,25216,33248,33253,33254). While rare, avocado can also cause acute food protein-induced enterocolitis syndrome (FPIES). This is a delayed, non-IgE-mediated gastrointestinal food hypersensitivity reaction most often reported in infants and young children. Symptoms of FPIES include excessive vomiting within 1-4 hours of avocado consumption and diarrhea. Many infants and children who experience FPIES after eating avocado will have the same reaction to other foods, such as milk, oat, and rice (100938).

General ...Broccoli is well tolerated when consumed as food. A thorough evaluation of safety outcomes when broccoli is taken as medicine has not been conducted.

Dermatologic ...Topically, allergic reactions to broccoli have caused contact dermatitis (14158).

Gastrointestinal ...Orally, loose stools, diarrhea, abdominal pain, and abdominal cramping have been reported following intake of broccoli seed and sprout extracts, particularly at high doses (114753).

Hepatic ...In one case report, a 56-year-old adult developed elevated transaminases, with alanine aminotransferase (ALT) 5. 8 times above normal, aspartate aminotransferase (AST) 2.4 times above normal, and gamma-glutamyl transpeptidase (GGT) 5.1 times above normal. This was thought to be related to the consumption of 800 mL of broccoli juice daily over a 4-week period. Values returned to normal 15 days after cessation of juice consumption (96191).

General ...Topically, cabbage leaf seems to be well-tolerated.

Dermatologic ...Some preliminary clinical research shows that application of cabbage leaf wraps to knee joints for at least 2 hours daily for 4 weeks is generally well-tolerated. Of the 27 patients using cabbage leaf wraps in this study, one patient reported an itching and burning sensation during the application. This patient was later found to have shingles, which may explain the adverse event (93671). However, in another case, a patient applying fresh Savoy cabbage leaves on his knee to reduce joint pain reported pain and burning after 4 hours of use. Skin patch and prick tests did not indicate an allergic reaction, and the patient's lesion improved with wet dressings, topical antibiotics, and oral antibiotics (93675).

Immunologic ...Topically, cabbage may cause contact dermatitis (93675). Allergic reactions to cabbage-related vegetables are rare. However, anaphylactic reactions to broccoli and cauliflower have been reported. Because the surface proteins believed to cause allergic reactions to brocolli are also found in cabbage, some patients allergic to brocolli or other vegetables in the Brassicaceae family may also be allergic to cabbage (92516).

Other ...Topical application of cabbage leaves to the breasts has been reported to stain clothes and put off an unpleasant smell (6781,6782).

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).
