LIKELY SAFE ...when used orally and appropriately in amounts commonly found in foods. Bilberry has Generally Recognized As Safe status (GRAS) for use in foods in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately for medicinal purposes. Bilberry fruit extracts have been used with apparent safety in clinical trials at a dose of up to 160 mg daily for up to 6 months (39,40,8139,9739,14280,35472,35510,35512,103190,104192,104195). A higher bilberry extract dose of 1.4 grams daily has been used with apparent safety for up to 4 weeks (104194). Whole bilberries or bilberry juice have also been consumed with apparent safety in quantities of 100-160 grams daily for up to 35 days (35463,91506).
POSSIBLY UNSAFE ...when the leaves are used orally in high doses or for a prolonged period. Death can occur with chronic use of 1.5 gram/kg daily (2).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in the amounts commonly found in foods.
However, there is insufficient reliable information available about the safety of bilberry when used in medicinal amounts during pregnancy and lactation; avoid using.
LIKELY SAFE ...when the fruit (nut) is consumed in amounts normally found in food.
POSSIBLY UNSAFE ...when the bark is used orally or topically, due to its juglone content (2). When applied topically, juglone-containing bark can cause skin irritation. When used orally on a daily basis, the juglone-containing bark of a related species (English walnut) is associated with increased risk of tongue cancer and lip leukoplakia (2,12). There is insufficient reliable information available about the safety of the leaf or hull when used orally as a medicine or when applied topically.
PREGNANCY AND LACTATION: LIKELY SAFE
when the fruit (nut) is consumed in amounts normally found in foods.
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when the bark is used orally or topically (12); avoid using.
There is insufficient reliable information available about the safety of black walnut leaf or hull when used orally in medicinal amounts during pregnancy or lactation; avoid using.
LIKELY SAFE ...when used orally and appropriately. Oral manganese is safe when used in doses below the tolerable upper intake level (UL) of 11 mg daily for adults 19 years and older (1994,7135). ...when used parenterally and appropriately. Parenteral manganese chloride and manganese sulfate are FDA-approved prescription products.
POSSIBLY UNSAFE ...when used orally in high doses. Doses exceeding 11 mg daily can cause significant adverse effects (7135). ...when used parenterally in moderate or high doses, long-term. Reports of neurotoxicity and Parkinson-like symptoms have been reported with parenteral nutrition manganese doses above 60 mcg daily. It is recommended that adults on long-term parenteral nutrition receive manganese in doses of no more than 55 mcg daily (99302).
LIKELY UNSAFE ...when inhaled in moderate doses, long-term. According to the US Occupational Safety and Health Administration (OSHA), the permissible exposure limit (PEL) for manganese is 5 mg/m3. Exposure to higher amounts of manganese dust or fumes has been associated with central nervous system toxicity, Parkinson-like symptoms, and poor bone health (61296,102516).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
Manganese is safe in children when used in daily doses less than the tolerable upper intake level (UL) of 2 mg in children 1-3 years, 3 mg in children 4-8 years, 6 mg in children 9-13 years, and 9 mg in children 14-18 years (7135).
CHILDREN: POSSIBLY UNSAFE
when used orally in excessive doses.
Daily doses greater than the UL are associated with a greater risk of toxicity (7135).
CHILDREN: LIKELY UNSAFE
when inhaled at moderate doses, long-term.
Exposure to high amounts of manganese dust has been associated with central nervous system toxicity and Parkinson-like symptoms (61296).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Manganese is safe when used in doses below the tolerable upper intake level (UL) of 11 mg daily during pregnancy or lactation in those aged 19 or older. However, those under 19 years of age should limit doses to less than 9 mg daily (7135).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
Doses over the UL are associated with a greater risk of toxicity (7135). Additionally, observational research shows that adults with higher blood manganese levels have greater odds of delivering low birth weight or small for gestational age (SGA) male, but not female, infants (102515).
PREGNANCY AND LACTATION: LIKELY UNSAFE
when inhaled at moderate doses, long-term.
Manganese salts can cross the placenta, and animal research suggests that large amounts of manganese may be teratogenic (61296).
LIKELY SAFE ...when used orally and appropriately, short-term. Valerian 300-600 mg daily has been safely used in clinical studies in over 12,000 patients for up to 6 weeks (2074,3484,3485,4032,15018,17577,17578,19409,96242,103221)(104010,105718). There is insufficient reliable information available about the safety of valerian when used orally for longer than 6 weeks.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
Valerian 160-320 mg has been used with apparent safety in children under 12 years of age for 4-8 weeks (14416).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when consumed in amounts commonly found in foods (5286).

Wheatgrass juice 60-100 mL daily has been used safely for up to 18 months (11165,85601,104878,104879). ...when wheatgrass cream is used topically. Wheatgrass 10% cream has been used safely for up to 6 weeks (85602). There is insufficient reliable information available about the long-term safety of wheatgrass when used medicinally.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Manganese Extra. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, barley might decrease the clinical effects of triclabendazole.
 Details
Animal research suggests that a diet supplemented with barley can reduce the bioavailability of triclabendazole when taken concomitantly (23884). This effect has not been shown in humans.
|
Theoretically, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity (1264). Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo (91507).
|
Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Details
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity (103191). This effect has not been reported in humans.
|
Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
Details
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib (97031). This interaction has not been reported in humans.
|
Theoretically, the risk for manganese toxicity might increase when taken with antipsychotic drugs.
Details
Hallucinations and behavioral changes have been reported in a patient with liver disease who was taking haloperidol and manganese. Researchers speculate that taking manganese along with haloperidol, phenothiazine-derivatives, or other antipsychotic medications might increase the risk of manganese toxicity in some patients (61493).
|
Theoretically, manganese might reduce the absorption of quinolone antibiotics.
Details
Manganese is a multivalent cation. Interactions resulting in reduced quinolone absorption have been reported between quinolones and other multivalent cations, such as calcium and iron (488).
|
Theoretically, manganese might reduce the absorption of tetracycline antibiotics.
Details
Manganese is a multivalent cation. Interactions resulting in reduced tetracycline absorption have been reported between tetracyclines and other multivalent cations, such as calcium and iron (488).
|
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).
|
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.
|
Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Details
|
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).
|
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.
|
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).
|
Some animal research shows that wheatgrass lowers blood glucose and stimulates the release of insulin from beta-cells (93018, 93019). Theoretically, wheatgrass might decrease blood glucose and have additive effects in patients treated with antidiabetes drugs, increasing the risk for hypoglycemia. Dose adjustments to diabetes medications may be necessarily. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.

Below is general information about the adverse effects of the known ingredients contained in the product Manganese Extra. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, barley is well tolerated.
Most Common Adverse Effects:
Orally: Abdominal distension, bloating, flatulence, unpleasant taste. Allergic reactions in sensitive individuals.
Topically: Allergic reactions in sensitive individuals.
Dermatologic ...Topically, barley malt contained in beer has been reported to cause contact dermatitis (33762). After occupational exposure, barley has been reported to cause contact dermatitis of the eyelids and extremities, as well as contact urticaria (33735,33770,33774).
Gastrointestinal
...When consumed orally, barley provides 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. Adverse effects usually subside with continued use (12514).
Barley contains gluten. In patients with biopsy-proven celiac disease, consuming barley can cause gastrointestinal upset and impairment of xylose excretion (33763,33772).
Immunologic
...Orally, consumption of beer has been reported to cause allergic reactions in sensitive individuals (33722,33724).
Symptoms included tingling in the face, lip, and tongue, angioedema, generalized urticaria, chest tightness, dyspnea, cough, fainting, and rhinoconjunctivitis. It can also cause anaphylaxis in sensitive individuals (317). Topically and with occupational exposure, barley has been reported to cause contact dermatitis and rash (33762,33735,33770,33774).
"Bakers' asthma" is an allergic response resulting from the inhalation of cereal flours by workers in the baking and milling industries, and has been reported to occur after barley flour exposure (1300,33756,33760). Cross-allergenicity has been shown to exist between different cereals (33758).
Pulmonary/Respiratory
..."Bakers' asthma" is an allergic response resulting from the inhalation of cereal flours by workers in the baking and milling industries, and has been reported to occur after barley flour exposure (1300,33756,33760).
Cross-allergenicity has been shown to exist between different cereals (33758).
By inhalation, barley flours may be a source of allergens in asthma (33764,33773). Inhalation of wild barley grass pollen may result in bronchial irritation or pneumonitis (33726,33755).
General
...Orally, bilberry fruit, juice, and extracts seem to be well tolerated.
Most Common Adverse Effects:
Orally: Dark-colored stools, flatulence, and gastrointestinal discomfort.
Gastrointestinal
...In one small clinical trial, mild-to-moderate flatulence was reported in 33% of patients taking sieved bilberries and concentrated bilberry juice (91506).
However, the patients in this study had ulcerative colitis, and the study lacked a control group, limiting the validity of this finding. In another small clinical study of males with age-related cognitive impairment, temporary adverse gastrointestinal (GI) effects were reported in 13% of patients drinking a combination of bilberry and grape juice. However, the adverse GI effect rate was identical in patients drinking a placebo juice (110641). A post-marketing surveillance report of 2295 patients using bilberry extract (Tegens) found that 1% of patients complained of GI discomfort and less than 1% experienced nausea or heartburn (35500).
Theoretically, fresh bilberry fruit may have laxative effects. One clinical trial noted an increased frequency of bowel movements following the administration of a combination formulation containing aerial agrimony parts, cinnamon quills, powdered bilberry fruit, and slippery elm bark (35462). It is unclear if these effects were due to bilberry, other ingredients, or the combination.
Other ...Orally, bilberry may cause discoloration of feces and the tongue. In one study, a dark-bluish to black discoloration of both the feces and the tongue was observed following consumption of sieved bilberries and concentrated bilberry juice. In one patient, a slight discoloration of the teeth has also been observed (91506). In another study, 50% of patients reported dark green stools after taking bilberry extract 700 mg twice daily for 4 weeks (104194).
General
...Orally, black walnut fruit (nut) is well tolerated.
However, the leaf, bark, and hull of black walnut contain high quantities of tannins, which may cause adverse effects when used orally or topically.
Most Common Adverse Effects:
Orally: The leaf, bark, and hull can cause gastrointestinal upset.
Topically: Hull preparations may cause a temporary yellow or brown discoloration at the site of application. The leaf, bark, and hull can cause skin irritation.
Serious Adverse Effects (Rare):
Orally: The bark may increase the risk for tongue cancer or lip leukoplakia when used long-term.
All routes of administration: Allergic reactions, including anaphylaxis.
Dermatologic ...Topically, black walnut leaf, bark, or hull may have an irritating effect on the skin due to tannin content. Black walnut hull preparations might cause a temporary yellow or brown discoloration of the skin at the site of application (12).
Gastrointestinal ...Orally, black walnut leaf, bark, or hull may cause gastrointestinal upset due to tannin content (12). Also, daily use of the juglone-containing bark of a related species (English walnut) is associated with increased risk of tongue cancer and lip leukoplakia (2,12).
Hepatic ...Orally, black walnut leaf, bark, or hull may cause liver damage if taken for extended periods of time due to tannin content (12).
Immunologic ...Tree nuts, which include black walnuts, can cause allergic reactions in sensitive individuals. Due to the prevalence of this allergy in the general population, tree nuts are classified as a major food allergen in the United States (105410).
Renal ...Orally, black walnut leaf, bark, or hull may cause kidney damage if taken for extended periods of time due to tannin content (12).
General
...Orally and parenterally, manganese is generally well tolerated when used in appropriate doses.
High doses might be unsafe.
Serious Adverse Effects (Rare):
All routes of administration: Neurotoxicity, including Parkinson-like extrapyramidal symptoms, when used in high doses.
Cardiovascular ...Chronic occupational exposure to manganese dust or fumes can cause orthostatic hypotension, and heart rate and rhythm disturbances (61363).
Endocrine ...Chronic occupational exposure to manganese dust or fumes can cause elevations in thyrotropin-releasing hormone (TRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) levels (61378).
Hepatic ...Manganese intoxication may cause cirrhosis and hepatic steatosis. In one case, a 13-year-old female with manganese intoxication developed severe, life-threatening neurological symptoms, with liver biopsy indicating incomplete cirrhosis and microvesicular steatosis. Chelation therapy and multiple rounds of therapeutic plasma exchange were required before symptoms resolved. The source of manganese exposure was not identified, and it is not clear if the impaired liver function contributed to the manganese accumulation or if elevated manganese exposure led to the liver damage.
Musculoskeletal ...Chronic occupational exposure to manganese dust or fumes has been associated with lower bone quality in females, but not males, suggesting that prolonged manganese exposure might increase the risk of osteoporosis in females (102516). A meta-analysis of 11 observational studies in adults also suggests that increased environmental exposure to airborne manganese sources is associated with lower motor function scores (108537).
Neurologic/CNS
...Orally, there is concern that higher doses of manganese might increase the risk of neurotoxicity, including Parkinson-like extrapyramidal symptoms (7135,10665,10666).
One severe case of irreversible Parkinson disease possibly related to taking manganese 100 mg daily for 2-4 years has been reported (96418). In another case, a 13-year-old female with manganese intoxication (diagnosed from blood manganese levels and cranial MRI evidence) developed severe neurological symptoms including loss of consciousness, decorticate posture, clonus, increased reflexes in the extremities, isochoric pupils, and no painful stimulus response. Liver biopsy also showed incomplete cirrhosis and microvesicular steatosis. The patient was intubated, and chelation therapy and multiple rounds of therapeutic plasma exchange were required before symptoms resolved. The source of the child's manganese exposure was not identified (112137). Individuals with impaired manganese excretion can also experience these effects even with very low manganese intake. Manganese accumulation due to chronic liver disease seems to cause Parkinson-like extrapyramidal symptoms, encephalopathy, and psychosis (1992,7135). One review recommends stopping supplementation if aminotransferase or alkaline phosphatase levels rise beyond twice normal (99302).
Chronic occupational exposure to manganese dust or fumes can also cause extrapyramidal reactions (1990,7135). In 1837, Couper observed that exposure to manganese dust particles produces a neurological syndrome characterized by muscle weakness, tremor, bent posture, whispered speech, and excess salivation (61264). Additionally, observational research in children has found that elevated manganese levels detected in the hair and fingernails due to environmental exposure may be associated with impaired neurocognitive function or development (108535). A meta-analysis of 11 observational studies in adults also suggests that increased environmental exposure to airborne manganese sources is associated with lower cognitive function scores (108537).
Intravenously, manganese might increase the risk of neurotoxicity when administered at high doses or for an extended duration. Cases of Parkinson-like symptoms have been reported in patients receiving parenteral nutrition containing more than 60 mcg of manganese daily. Moderate MRI intensity uptake for manganese in the globus pallidus and basal ganglion areas of the brain has been shown in patients receiving parenteral manganese (96416,99302).
Psychiatric ...Chronic occupational exposure to manganese dust or fumes can cause mood disturbance and dementia (1990,7135). A case report describes a man who presented with confusion, psychosis, dystonic limb movements, and cognitive impairment after chronic industrial manganese exposure (99415). Symptoms of manganese toxicity from inhalational exposure develop slowly with initial fatigue and personality changes, progressing to hallucinations, delusions, hyperexcitability, Parkinson-like symptoms, dystonia, and dementia (99415). Additionally, observational research has found that chronic environmental exposure to manganese sources such as mining operations and various industrial processes may be associated with a greater risk for developing symptoms of depression (108536).
Pulmonary/Respiratory ...Chronic occupational exposure to manganese dust or fumes can cause acute chemical pneumonitis, pulmonary edema, or acute tracheobronchitis (61495).
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).
General ...Orally, wheatgrass is generally well tolerated. It can cause nausea, anorexia, and constipation (11165).
Gastrointestinal ...Orally, wheatgrass may cause nausea, anorexia, and constipation (11165).
Immunologic ...Wheat can cause allergic reactions in sensitive individuals. Due to the prevalence of this allergy in the general population, wheat and wheat products, such as wheatgrass, are classified as major food allergens in the United States (105410).
