• Coronary heart disease (CHD). A diet high in soluble fiber, such as that found in oats, reduces the risk of CHD. Details: Clinical research shows that a diet containing foods high in fiber, such as oats, oat bran, or whole oat flour, reduces the risk of CHD (2737,4960,4962,4963,4964,4965,4966,4967,4968). In 1993, the US Food and Drug Administration (FDA) approved a health claim stating that consuming at least 3 grams of soluble fiber per day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of CHD (102336). However, clinical studies show that at least 3.6 grams of soluble fiber daily is needed to reduce the risk of CHD (5786,5787,5788,5794,5795,5796).
• Dyslipidemia. A diet rich in soluble fiber, such as that found in oats, can reduce cholesterol by a moderate amount. Details: Oats, oat bran, and other soluble fibers can modestly reduce total and low-density lipoprotein (LDL) cholesterol, especially when consumed as part of a diet low in saturated fat. Consuming 56-150 grams of whole oat products such as oatmeal and oat bran, containing 3.6-10 grams of soluble fiber daily, can significantly lower total and LDL cholesterol levels. For each gram of soluble fiber consumed, total cholesterol decreases by about 1.4 mg/dL and LDL by about 1.2 mg/dL. Eating 3-10 grams of soluble fiber daily can reduce total cholesterol by about 4-14 mg/dL (4976,4977,5786,5788,5792,5794,5795,8521,107749,113488,113495). For example, eating 3 bowls of oatmeal (28 gram servings) daily, providing a total of 3 grams of soluble fiber daily, can decrease total cholesterol by about 5 mg/dL (5788). However, consuming more than 10 grams of soluble fiber daily doesn't seem to increase effectiveness (5788). A meta-analysis comparing the effects of oats and isolated beta-glucans shows that both products similarly impact lipid profiles, suggesting that the bioactive component of oats are beta-glucans (113488). Oat bran products, such as oat bran muffins and oat bran flakes, may vary in their ability to lower cholesterol, depending on the total soluble fiber content and other dietary variables (6188). Whole oat products might be more effective for lowering LDL and total cholesterol than foods containing oat bran plus soluble fiber (10145). Although oats are shown to lower total and LDL cholesterol, a meta-analysis and a small clinical study in adults with and without dyslipidemia shows that consuming oatmeal or oat products does not reduce triglycerides or increase high-density lipoprotein (HDL) cholesterol when compared with controls (113488,113495).

POSSIBLY EFFECTIVE

• Diabetes. A diet rich in whole grains, such as oats, may help prevent diabetes or improve blood glucose control in patients with type 1, type 2, or gestational diabetes. Details: Population research shows that for every 16 gram daily serving of whole grains, including oats, there is a 7% to 11% lower risk of developing type 2 diabetes (100622). There is also evidence that consuming oats can decrease blood glucose and insulin levels, as well as lipid levels, in patients with diabetes. The glycemic effects of oats depend on the level of processing of the oat products. Consuming intact oat kernels or thick-cut oats (>0.6 mm) reduces postprandial blood glucose and insulin, but consuming thin-cut, or "quick", oats has no effect (105536). Clinical research shows that consuming oats and oat bran for 4-8 weeks decreases pre-prandial blood glucose, 24-hour plasma glucose, glycated hemoglobin (HbA1c), insulin levels, and low-density lipoprotein (LDL) cholesterol in people with type 2 diabetes (4980,4982,6266,103345). Various doses have been used, including 3 grams of soluble fiber daily, or bread providing 34 grams of total fiber daily (9 grams of soluble fiber) (4961,4980). Additional clinical research in obese adults with type 2 diabetes shows that eating whole grain oats 50-100 grams daily in place of other carbohydrates reduces postprandial blood glucose by 19-27 mg/dL when compared with other carbohydrates in a healthy diet. After 1 year, the groups consuming 50 grams and 100 grams of oats had an additional 0.48% and 0.64% reduction in HbA1c, respectively, when compared with the regular healthy diet group (97520). There is also some evidence that consuming oats 50 grams daily, containing 25 grams of soluble fiber, might be more effective for improving glycemic control and decreasing hyperinsulinemia than the standard moderate fiber diet recommended by the American Diabetes Association (ADA) (6266). Oats have also been evaluated in adolescents with type 1 diabetes. One very small clinical study shows that taking 50 grams of a specific oat product (Betaglucare), providing beta-glucans 6 grams, in three divided doses daily for one week is beneficial for glycemic control and variability when compared with a standard diet without beta-glucans or with taking only 25 grams of the product daily. Maximal, mean, and pre- and post-meal blood glucose levels were modestly lower, and minimal blood glucose levels were modestly higher. Most measures of glycemic variability were statistically different, although there were no differences in the duration of hypoglycemia or hyperglycemia between groups (105261). Oats have also been evaluated in patients with gestational diabetes. A randomized, controlled trial shows that taking 30 grams of a specific oat bran product (OAB; Golden Light Cup Company) orally twice daily at lunch and dinner for 4 weeks improves mean fasting blood glucose and two-hour postprandial glucose when compared with a control group. After 4 weeks, the mean fasting blood glucose and 2-hour postprandial glucose in the treatment group were 85 mg/dL and 104 mg/dL, respectively, compared with 93 mg/dL and 117 mg/dL, respectively, in the control group (107751). The validity of this study is limited by the short treatment duration and lack of follow-up.
• Gastric cancer. A diet rich in soluble fiber, such as that found in oats, might reduce the risk of gastric cancer. Details: Observational research has found that consuming a diet that includes cereal fiber, such as oats and oat bran, might reduce the incidence of gastric cancer (10435).

POSSIBLY INEFFECTIVE

• Colorectal cancer. Regular consumption of oats does not seem to reduce the risk of colorectal cancer. Details: Observational research has found that consuming oat bran or oats orally doesn't seem to reduce the risk of colon cancer. Additionally, consuming fiber, including oat-bran fiber, is not associated with a reduction in the risk for recurrence of colorectal adenomas (4820,5104).

• Acne. Although there is interest in using topical oats for acne, there is insufficient reliable information about the clinical effects of oats for this purpose.
• Anxiety. Although there is interest in using oral oats for anxiety, there is insufficient reliable information about the clinical effects of oats for this purpose.
• Atopic dermatitis (eczema). Topical colloidal oatmeal cream may be beneficial in patients with atopic dermatitis. Details: Preliminary clinical research shows that applying a cream containing colloidal oatmeal 1% daily for 2 weeks moderately reduces the severity of atopic dermatitis when compared with baseline (103344). The validity of this finding is limited by the lack of a comparator group. Other research suggests that colloidal oatmeal may be beneficial when used in combination with topical steroids. Clinical research shows that the benefits obtained from applying an ointment containing fluocinolone 0.025% to the hands for 2 weeks were better maintained in the patients who also used a cream containing colloidal oatmeal 1% during this time period and for an additional 4 weeks when compared with patients using fluocinolone and the cream base without colloidal oatmeal. Quality of life was also improved in the patients using colloidal oatmeal (103340).
• Breast cancer. Observational research suggests that regular oatmeal intake may be associated with reduced mortality from breast cancer. Details: Population research in postmenopausal patients has found that those who have eaten 50 grams of oatmeal daily prior to a breast cancer diagnosis have a 20% reduced risk of all-cause mortality in the 7 years following the diagnosis when compared with patients who have not eaten oatmeal. However, no benefit was seen when post-diagnostic oatmeal intakes were examined (103343).
• Burns. Although there is interest in using topical oats for burns, there is insufficient reliable information about the clinical effects of oats for this purpose.
• Chronic fatigue syndrome (CFS). Although there is interest in using oral oats for CFS, there is insufficient reliable information about the clinical effects of oats for this purpose.
• Cognitive function. It is unclear if oral oats are beneficial in healthy adults with mild memory impairment. Details: Preliminary clinical research in healthy middle-aged adults with self-reported memory decline shows that consuming a specific wild green-oats extract (Neuravena, Frutarom) 800 mg as a single dose improves overall speed, but not overall accuracy, of cognitive performance when compared with placebo. However, a higher dose of 1600 mg was ineffective (97519).
• Dry skin. It is unclear if applying lotion containing colloidal oat extract improves dry skin to a greater extent than other lotion products. Details: Preliminary clinical research shows that applying a lotion containing colloidal oat extract (Aveeno Active Naturals Skin Relief 24Hr Moisturizing Lotion, Johnson & Johnson) twice daily for 2 weeks improves itchiness, cracking, scaling, dryness, and roughness when compared to baseline in females with dry skin (91458). Additional preliminary clinical research shows that applying a colloidal oatmeal lotion to the legs twice daily for three weeks reduces skin dryness and improves skin integrity when compared to baseline in adults with dry skin (97518). The validity of these findings is limited by the lack of a comparator group.
• Exercise-induced muscle soreness. It is unclear if oral oats are beneficial for exercise-induced muscle soreness. Details: A small clinical trial shows that eating two cookies containing oat flour 60 grams daily for 8 weeks reduces muscle soreness 48 or 72 hours after downhill running when compared with baseline (103341).
• Fat redistribution syndrome. It is unclear if oral oats are beneficial for fat redistribution syndrome. Details: Consumption of a high fiber diet, including oats, with adequate energy and protein might prevent fat deposition in patients with HIV. A one-gram increase in total dietary fiber may decrease the risk of fat deposition by 7% (12517).
• Gallbladder disease. Although there is interest in using oral oats for gallbladder disease, there is insufficient reliable information about the clinical effects of oats for this purpose.
• Hypertension. It is unclear if oral oats are beneficial for hypertension. Details: A meta-analysis of 21 clinical studies in healthy adults and those with a variety of metabolic conditions including hypertension shows that consumption of oat products reduces systolic blood pressure (SBP) by 3 mmHg but has no effect on diastolic blood pressure (DBP) when compared with control. Subgroup analysis suggests that consuming oat products reduces SBP by 10 mmHg in patients with hypertension at baseline. An additional subgroup analysis suggests that consuming at least 5 grams of beta-glucan-enriched oats daily or consuming oats for a duration at least 8 weeks reduces SBP and DBP (113494). Observational research has found that consumption of oats as oatmeal or oat cereal does not seem to reduce DBPor SBP in males with minor elevations in blood pressure or patients with dyslipidemia (2956,113495). A randomized, controlled trial in patients with stage 1 hypertension receiving dietary guidance shows that taking 30 grams of oat bran, providing 8.9 grams of dietary fiber, once daily with breakfast or in between meals for 3 months improves various blood pressure measures when compared with dietary guidance alone. After 3 months of treatment, 24-hour maximum SBP and DBP decreased by 14 mmHg and 11 mmHg, respectively, and office SBP and DBP decreased by 15 mmHg and 10 mmHg, respectively. Oat consumption may also have impacted antihypertensive medication use. Two patients in the control group increased doses of antihypertensive medications, whereas 6 patients in the treatment group decreased doses and 1 patient discontinued use (107750). The effect of oral oat bran on patients with stage 2 hypertension or pre-hypertension is unknown.
• Irritable bowel syndrome (IBS). Although there is interest in using oral oats for IBS, there is insufficient reliable information about the clinical effects of oats for this purpose.
• Metabolic syndrome. Limited research suggests that oats may not be beneficial for metabolic syndrome. Details: Preliminary clinical research in adults with metabolic syndrome shows that adding oat bran 40 grams daily for 6 weeks to a low-calorie diet does not reduce the incidence of metabolic syndrome. Oat bran also does not improve body weight, blood pressure, low-density lipoprotein (LDL) cholesterol, triglycerides, or blood glucose levels when compared with a low-calorie diet alone in patients with metabolic syndrome (103342).
• Osteoarthritis. Although there is interest in using oral oats for osteoarthritis, there is insufficient reliable information about the clinical effects of oats for this condition.
• Pruritus. Applying oat lotion topically may improve some types of pruritus. Details: Preliminary clinical research shows that applying an oat lotion (Espanol) twice daily for up to 2 weeks can decrease itching intensity by about 20% when compared to baseline in patients with pruritus associated with chronic kidney disease (uremic pruritus). This decrease is similar to the effects of applying vinegar 5% solution or taking hydroxyzine 10 mg orally. However, applying the oat lotion does not appear to decrease the frequency of itching (91457).
• Psoriasis. Although there is interest in using topical oats for psoriasis, there is insufficient reliable information about the clinical effects of oats for this purpose.
• Rheumatoid arthritis (RA). Although there is interest in using oral oats for RA, there is insufficient reliable information about the clinical effects of oats for this purpose.
• Stroke. It is unclear if oral oats are beneficial for reducing the risk of stroke. Details: Population research suggests that consuming oatmeal for breakfast once weekly might reduce the incidence of stroke by a small amount when compared with consuming white bread or eggs for breakfast (103337).
• Ulcerative colitis. Oral oats have only been evaluated in combination with other ingredients; their effect when used alone is unclear. Details: Preliminary clinical research shows that taking a specific oat-based product (Profermin, Nordisk Rebalance) containing fermented oat flour, Lactobacillus plantarum, barley malt flour, and lecithin, 250 mL orally twice daily for 8 weeks, reduces disease activity and increases remission in about two-fold more patients with relapsing ulcerative colitis, when compared with treatment with a specific nutritional beverage (Fresubin Original, Fresenius Kabi) (90271).
• Wound healing. Although there is interest in using topical oats for wound healing, there is insufficient reliable information about the clinical effects of oats for this purpose. More evidence is needed to rate oats for these uses.

POSSIBLY EFFECTIVE

• Insomnia. Most research shows that taking valerian whole root extract 300-600 mg daily modestly improves subjective sleep quality, although it might take up to 4 weeks to provide benefit. Valerian does not seem to improve sleep latency, sleep duration, or insomnia severity. Details: Although there is a great deal of conflicting research, overall, taking valerian 300-600 mg before bedtime seems to improve sleep quality when compared with placebo. In contrast, no consistent benefit has been seen for sleep latency, sleep duration, or insomnia severity (15046,17577,19406,19409,104010). Older meta-analyses show that valerian root improves sleep quality regardless of its formulation. However, the most recent meta-analysis shows that valerian whole root extract improves sleep quality, while it's unclear whether an unspecified valerian extract is effective (17577,19406,104010). These analyses are limited by significant heterogeneity in valerian dosage and formulation, treatment duration, and included patient populations. Some experts claim that valerian does not work acutely for sleep, and it can take up to 4 weeks for a benefit to be seen (10209,104010). Indeed, most short-term studies assessing valerian as a single dose, or used daily for up to one week, show no benefit for sleep quality when compared with placebo (19407,19408,19411,19414). However, a meta-analysis of studies lasting 4 weeks or longer also did not find a consistent benefit (104010). The benefits of valerian for sleep might vary in different patient populations. A large post-marketing surveillance study in children with restlessness or dyssomnia under the age of 12 has found that taking a specific combination product (Euvegal Forte, Dr. Willmar Schwabe Pharmaceuticals) containing valerian root extract 160 mg and lemon balm extract 80 mg 1-2 tablets once or twice daily is associated with moderate sleep improvement (14416). Also, one clinical study in postmenopausal adults shows that taking valerian root extract 530 mg (Sadamine) twice daily for 28 days moderately improves sleep quality when compared with placebo (19425). Another clinical study in patients undergoing treatment for cancer shows that taking valerian 450 mg 1 hour before bedtime for 8 weeks does not improve objective sleep measures, but might improve subjective sleep ratings and mood, when compared with placebo (19424). Small clinical studies in adults on hemodialysis show that taking valerian 530 mg before bedtime for 1 month improves sleep quality when compared with baseline or placebo. (105718,110712). In one of these studies, improvements in sleep quality were similar when compared with gabapentin (110712). Research also shows that taking specific combination products containing valerian and other ingredients can improve sleep quality. These combination products have combined valerian with hops; lemon balm (Euvegal Forte); lemon balm and hops (Valerina Natt); or passionflower and hops (NSF-3, M/s Tablets India) (10423,15018,19413,19417,19418,19419,88193,89408). Finally, limited research has compared valerian to benzodiazepines. A small clinical study in patients with non-organic insomnia shows that taking valerian extract (LI 156, Sedonium) 600 mg daily for 6 weeks seems to be no different for improving sleep quality when compared with taking low-dose oxazepam 10 mg (19416). Valerian might also improve sleep quality in patients who are resistant to chronic benzodiazepine therapy. In one small study, after tapering the benzodiazepine over two weeks, valerian extract 100 mg three times daily for 15 days improves sleep quality when compared with placebo (8006).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Anxiety. It is unclear if valerian is beneficial for anxiety. Details: Meta-analyses of heterogeneous clinical research show that there is insufficient and contradictory evidence on the use of valerian root for anxiety (104010,110711). However, one analysis suggests that using whole root preparations seems to have greater efficacy than valerian extracts (104010). These meta-analyses are limited by significant heterogeneity in valerian dosage and formulation, treatment duration, and patient populations and concerns related to publication bias (104010,110711). One small clinical study in patients with generalized anxiety disorder (GAD) shows that taking valerian extract containing 81.3 mg valepotriates daily for 4 weeks is no different for reducing anxiety scores when compared with diazepam 6.5 mg or placebo (9896). This study was not adequately powered to detect a difference between groups. Also, a small, quasi-randomized trial in adults with poor sleep quality who are undergoing hemodialysis shows that taking a specific valerian root product (Sedamin, Goldaru Company) 530 mg daily for 1 month improves anxiety scores by 2-3.9 times when compared with placebo. However, not all patients reported anxiety at baseline (105718). In contrast, a small clinical study in healthy adults shows that taking a combination of herbal extracts containing valerian root, passionflower, ballota, and hawthorn (Euphytose) daily for 14 days reduces subjective anxiety and objective sympathetic and autonomic nervous system activation in response to a psychosocial stressor when compared with placebo (111222). It is unclear if these effects are due to valerian, other ingredients, or the combination.
• Delirium. Oral valerian has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in adult intensive care unit (ICU) patients with agitation and delirium receiving quetiapine 50-200 mg every 12 hours shows that taking 5 mL of syrup containing valerian root 625 mg and an extract of lemon balm leaf 50 mg every 12 hours improves agitation from baseline similarly to placebo. It is unclear if the improvement from baseline differed between groups (106627).
• Depression. It is unclear if valerian is beneficial in patients with depression. Details: A retrospective case series in patients with mild to moderate depression and reports of anxiety has found that taking high-dose valerian 1000 mg with St. John's wort is associated with more rapidly improved depressive symptoms than low-dose valerian 500 mg with St. John's wort (19402). The validity of this study is limited by its retrospective nature and small size. Also, it is unclear if this effect is due to valerian, St. John's wort, or the combination. One small, quasi-randomized trial in adults with poor sleep quality who are undergoing hemodialysis shows that taking a specific valerian root product (Sedamin, Goldaru Company) 530 mg daily for 1 month improves depression scores by 2-3.9 times when compared with placebo. However, not all patients reported depression at baseline (105718).
• Dysmenorrhea. One small study suggests that oral valerian may reduce symptoms of dysmenorrhea. Details: A small clinical study shows that taking powdered valerian root 255 mg three times daily for two menstrual cycles reduces pain severity associated with menstruation when compared with placebo (19342).
• Menopausal symptoms. Small studies suggest that oral valerian may reduce menopausal symptoms. Details: Two small clinical studies in postmenopausal adults show that taking valerian root (Zardband or Goldaroo Co.) 225 mg three times daily or 530 mg twice daily for 2 months moderately reduces hot flash frequency and severity when compared with placebo (89407,96243). Another small study in adults with menopausal symptoms shows that taking a combination of valerian and fennel extracts 500 mg twice daily for 8 weeks reduces the severity of hot flashes and improves sleep quality but does not reduce the duration or frequency of hot flashes when compared with control (112369). It is unclear if these effects are due to valerian, fennel, or the combination. All 3 studies were conducted in Iran, so it is unclear if these results are generalizable to other geographic locations.
• Premenstrual syndrome (PMS). One small study suggests that oral valerian may reduce PMS symptoms. Details: A small clinical study in young adults with PMS shows that taking valerian root extract (Goldaroo Co.) 530 mg twice daily on the last 7 days of the menstrual cycle for 3 cycles moderately reduces the severity of self-reported PMS symptoms when compared with placebo (96239).
• Pre-procedural anxiety. One small study suggests that oral valerian may reduce anxiety during wisdom tooth extraction. Details: A small crossover clinical study in patients undergoing impacted mandibular molar extraction shows that taking valerian extract (Dermatologica Ltda.) 100 mg one hour prior to the extraction reduces physiological responses to anxiety to a satisfactory but lesser degree than midazolam 15 mg. Patients expressed no clear preference for either valerian or midazolam for reducing perioperative anxiety (102242). The validity of these findings is limited by the use of subjective outcome measures.
• Restless legs syndrome (RLS). It is unclear if oral valerian is beneficial in patients with RLS. Details: A small clinical study in patients with RLS shows that taking valerian (Pharmavite, LLC) 800 mg daily for 8 weeks does not improve RLS symptoms or sleep latency when compared with placebo (19422). However, this study was not adequately powered to detect a difference in RLS symptoms between groups. Conversely, another small clinical study in adults with RLS on hemodialysis shows that taking valerian 530 mg nightly before bed for 1 month reduces symptoms of RLS when compared to baseline; however, valerian's effects were weaker when compared with gabapentin 100 mg nightly (110712). The validity of this study is limited by a lack of a placebo group and a small sample size.
• Stress. Two small studies suggest that oral valerian may reduce the stress response in healthy adults who are performing a stressful mental task or a verbal presentation. Details: Two small clinical studies in healthy volunteers shows that taking valerian 100 mg once or 600 mg daily for 7 days prior to participating in a mental stress task or public verbal test reduces physiologic responses to stress and feelings of anxiety when compared to baseline (9893,9895). The validity of these findings is limited by the lack of statistical comparison to the control group. Another small study in healthy volunteers shows that taking a specific combination product containing valerian 360 mg and lemon balm 240 mg (Songha Night, Pharmaton Natural Health Products) reduces anxiety associated with laboratory-induced stress. However increasing the dose to valerian 1080 mg and lemon balm 720 mg seems to increase anxiety (19405).
• Tension headache. One small study suggests that oral valerian may reduce tension headache. Details: A small clinical study in patients with frequent tension headaches shows that taking valerian root extract (Sedamin, Goldaru Pharmaceutical Company) 1060 mg daily after dinner for one month modestly reduces headache severity and disability when compared with placebo (103221). More evidence is needed to rate valerian for these uses.

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, oats may have additive effects with antidiabetic agents and might increase the risk of hypoglycemia.  Details Consuming oats can decrease blood glucose in patients with diabetes (4980,4982,6266,103345). In those who require insulin, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control (103336).

INSULIN Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Concomitant use of oats and insulin might increase the risk of hypoglycemia.  Details In patients with insulin-dependent type 2 diabetes, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control (103336).

ALCOHOL (Ethanol) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = B Valerian can have additive sedative effects when used concomitantly with alcohol.  Details Valerian has sedative effects (9894). Theoretically, valerian might have an additive sedative effect when combined with alcohol. Excessive sedation has been reported in an alcohol-abusing individual who took valerian and Gingko biloba (19426). However, the potential interaction between valerian and alcohol has been disputed in other research. Limited evidence suggests that a combination of valerian 160 mg and lemon balm 80 mg (Euvegal) does not cause further deterioration in reaction ability and reaction rate when taken with alcohol as compared to the effects of alcohol alone (19427).

ALPRAZOLAM (Xanax) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = B Valerian can have additive sedative effects when used with alprazolam. Also, valerian in high doses might modestly increase alprazolam levels, though this is not likely to be clinically significant.  Details Valerian has sedative effects (9894). Theoretically, valerian might cause additive sedation when combined with alprazolam. Also, a small pharmacokinetic study shows that taking valerian extract 1000 mg daily (providing 11 mg valerenic acid) might increase alprazolam levels by about 19%. This might be due to valerian's mild inhibition of cytochrome P450 3A4 (CYP3A4) (13014). Despite being statistically significant, this increase is not likely to be clinically significant.

CNS DEPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.  Details Theoretically, concomitant use of valerian and drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects (3486,12720,19429).

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Unlikely •  Level of Evidence = B Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.  Details Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme (13014,13536,19430,19431). In one PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days did not affect the metabolism of dextromethorphan, a CYP2D6 substrate. In another PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of debrisoquine, an accepted CYP2D6 probe-substrate (13014,13536).

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = B Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.  Details Although some in vitro evidence suggests that valerian extract might inhibit or induce CYP3A4, clinical pharmacokinetic (PK) studies show that valerian does not have a clinically significant effect on the CYP3A4 enzyme (6450,12214,13014,13536,19431). In one PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of midazolam, an accepted CYP3A4 probe-substrate. In another PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days modestly increases levels of alprazolam, a CYP3A4 substrate, suggesting mild inhibition of CYP3A4 (13014,13536). However, this mild inhibition is unlikely to be clinically relevant.

GLUCURONIDATED DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.  Details In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7 (81685).

General ...Orally, Ignatius bean is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity. Ignatius bean 30-50 mg, which contains approximately 5 mg of strychnine, can cause restlessness, anxiety, heightened sense perception, enhanced reflexes, equilibrium disorders, painful back and neck stiffness, twitching, spasms of jaw and neck muscles, myoglobinuric renal failure, rhabdomyolysis, extreme muscle tension, and agitation and difficulty breathing after respiratory spasms (55854). Seizures have been reported to occur within 15 minutes of Ignatius bean ingestion (17). Taking Ignatius bean at a dose of 1-2 grams can be fatal (18). Most deaths occur within 3-6 hours of ingestion and are due to respiratory and subsequent cardiac arrest, anoxic brain damage, or multiple organ failure secondary to hyperthermia (18,505).
Long-term consumption of Ignatius bean can cause strychnine accumulation, particularly in individuals with liver damage. Chronic use can cause death after a period of weeks (18).
By inhalation, Ignatius bean has been reported to cause seizures (17).

Cardiovascular ...Orally, Ignatius bean 1-2 grams has been reported to cause fatal cardiac arrest within 3-6 hours of ingestion (55853,55855).

Endocrine ...Orally, Ignatius bean 1-2 grams has been reported to cause hyperthermia resulting in multiple organ failure within 3-6 hours of ingestion (18,505).

Musculoskeletal ...Orally, Ignatius bean 30-50 mg, which contains approximately 5 mg of strychnine, has been reported to cause rhabdomyolysis, painful back and neck stiffness, spasms of jaw and neck muscles, and extreme muscle tension (55854).

Neurologic/CNS ...Orally, Ignatius bean 30-50 mg, which contains approximately 5 mg of strychnine, has been reported to cause restlessness, anxiety, heightened sense perception, enhanced reflexes, and twitching. It has also been reported to cause seizures within 15 minutes of ingestion (55854). Taking 1-2 grams of Ignatius bean has been reported to cause death due to anoxic brain damage (18,505).
By inhalation, Ignatius bean has been reported to cause seizures within 5 minutes (17).

Pulmonary/Respiratory ...Orally, Ignatius bean 30-50 mg, which contains approximately 5 mg of strychnine, has been reported to cause respiratory acidosis and difficulty breathing due to respiratory spasms (55854).

General ...Orally, oats are well tolerated.
Most Common Adverse Effects:
Orally: Abdominal distension, bloating, flatulence, and unpleasant taste.
Topically: Burning, contact dermatitis, itching, and redness.

Dermatologic ...Topically, oat-containing preparations can cause contact dermatitis (12515). Redness, burning, and itchiness have also been reported (103340).

Gastrointestinal ...When consumed orally, oats provide fiber. Increasing fiber in the diet can cause flatulence, bloating, abdominal distention, and unpleasant taste. To minimize side effects, doses should be slowly titrated to the desired level. These adverse effects usually subside with continued use (12514).
In patients who have difficulty chewing food, or those with conditions that decrease small bowel motility, oat bran may cause bezoars (concretions) and intestinal obstruction. Oats and oat bran are unlikely to cause obstruction without other causative factors (4979,4985).

Immunologic ...In a case report, a 45-year-old male developed acute generalized urticaria, facial angioedema, and dyspnea immediately after consuming oat flour. The reaction resolved after emergency care for anaphylaxis. Further investigation revealed an IgE-mediated hypersensitivity reaction to oat proteins (113490).

General ...Orally, valerian is generally well-tolerated.
Most Common Adverse Effects:
Orally: Dizziness, drowsiness, and mental slowness. Other reported side effects include headache, gastrointestinal upset, excitability, and vivid dreams. When used chronically and abruptly stopped, symptoms of withdrawal such as tachycardia, anxiety, irritability, and insomnia might occur. Advise patients to taper doses slowly after extended use.
Serious Adverse Effects (Rare):
Orally: Several case reports raise concerns about hepatotoxicity after the use of valerian and valerian-containing multi-ingredient dietary supplements. Withdrawal from chronic valerian use has been associated with cases of cardiac failure and hallucinations.

Cardiovascular ...When used orally in high doses for an extended period of time, valerian withdrawal has been associated with tachycardia and high output cardiac failure in one patient with a history of coronary artery disease (3487). Chest tightness has been reported for an 18-year-old female who took 40-50 capsules containing valerian 470 mg/capsule (659). A case of severe hypotension, suspected to be due to vasodilation, hypocalcemia, and hypokalemia, has been reported for a patient who injected an unknown quantity of a crude tap water extract of raw valerian root (81734).

Dermatologic ...Orally, valerian might rarely cause a rash. A case of valerian-related rash that resolved after valerian root discontinuation was reported in clinical research (19422).

Gastrointestinal ...Orally, valerian has been associated with increased incidence of gastrointestinal problems including diarrhea, nausea, vomiting, and stomach pain (15046,19406,19407,19422,110712). In one individual, taking 20 times the normal dose caused abdominal cramping (659).

Hepatic ...There have been several case reports of hepatotoxicity associated with the use of multi-ingredient oral preparations containing valerian (8243,96241). In one case report, a 57-year-old man presented with acute hepatitis after consuming a cold and flu remedy containing valerian 2 grams for 3 days; the remedy also contained white willow, elderberry, and horseradish. Although the use of the cold and flu remedy was discontinued one month prior to symptom presentation, the acute hepatitis was attributed to valerian root and treated with steroids (96241). It is possible, however, that some of these preparations may have been adulterated with hepatotoxic agents (8243).
Hepatotoxicity involving long-term use of single-ingredient valerian preparations has also been reported (3484,17578). Also, a case of a 38-year-old female with liver insufficiency and cirrhosis of a vascular parenchymal nature who developed hepatotoxic symptoms following valerian and ethyl-alcohol abuse has been reported (81697). Symptoms resolved and laboratory values normalized following intense plasmapheresis treatment. Another case of acute hepatitis characterized by elevated aminotransferases, mild fibrosis, and liver inflammation has been reported for a 50-year-old female who consumed valerian root extract 5 mL three times weekly along with 10 tablets of viamine, a product containing dry valerian extract 125 mg/tablet, for 2 months (81696). Because a variety of doses were used in these cases, and many people have used higher doses safely, these hepatotoxic reactions might have been idiosyncratic. Tell patients the long-term effect of valerian on liver function is unknown.

Musculoskeletal ...In a case report, combined intake of valerian and passionflower caused throbbing and muscular fatigue when taken concomitantly with lorazepam (19429).

Neurologic/CNS ...Orally, valerian might cause dizziness, headaches, fatigue, sleepiness, and mental dullness (3484,17578,19411,19422,81723,89407). The severity of adverse effects appears to increase with higher doses (19411). However, taking valerian extracts in doses up to 1800 mg does not appear to significantly affect mood or psychomotor performance (10424,15044). Valerian does not usually have a negative impact on reaction time, alertness, and concentration the morning after intake (2074,8296). Clinical research shows that a single dose of valerian root 1600 mg is not associated with any changes in sleepiness, reaction time, or driving performance within 1-4 hours after intake (96240). More serious side effects may occur when valerian is taken at higher doses. In one individual, 20 times the normal dose caused tremor of the hand and foot and lightheadedness (659). In a case report, combined intake of valerian and passionflower caused shaking of the hands and dizziness when taken concomitantly with lorazepam (19429).

Psychiatric ...Orally, valerian has been associate with reports of restlessness, excitability, uneasiness, agitation, and vivid dreams (3484,17578,19411,19422). Chronic use and rapid cessation can lead to withdrawal syndrome with symptoms of agitation, insomnia, and hallucinations (104003). There appears to be a trend towards increased severity of adverse effects with higher doses (19411). A case of acute hypomania has been reported for a 21-year-old female patient who took a valerian decoction in water each night for one month to treat subclinical anxiety. Symptoms included euphoric mood, rapid speech, and increased sociability and sexual interest. Following cessation of valerian use and treatment with quetiapine 100 mg daily for two weeks, the patient recovered (89405). In another case report, an 85-year-old male with mild cognitive impairment, major depression, anxiety, and chronic kidney disease presented to the emergency department with hallucinations, confusion, and agitation thought to be due to abrupt cessation after taking valerian 600 mg daily for about 6 months. The symptoms resolved in about 5 days (104003).
