INSUFFICIENT RELIABLE EVIDENCE to RATE

• Age-related cognitive decline. It is unclear if oral hops-derived bitter acids are beneficial for memory and attention in patients with age-related cognitive decline. Details: A small exploratory clinical study in older adults aged 45-64 years, with self-awareness of cognitive decline, shows that taking matured hops bitter acids (Kirin Holdings Co. Ltd) 35 mg daily for 12 weeks does not improve memory, attention, or performance on most cognitive tests when compared with placebo (102899). A follow-up clinical study in patients aged 45-69 years with subjective cognitive decline shows that taking the same dose of the same product for 12 weeks also does not improve memory, learning, or selective attention, but might improve divided attention as measured on the Symbol Digit Modalities Test (SDMT), when compared with placebo (105953). Both studies were funded by the supplement manufacturer and conducted in Japan; it is unclear if these findings are generalizable to other geographic locations.
• Anxiety. Although there is interest in using oral hops for anxiety, there is insufficient reliable information about the clinical effects of hops for this condition.
• Attention deficit-hyperactivity disorder (ADHD). Although there is interest in using oral hops for ADHD, there is insufficient reliable information about the clinical effects of hops for this condition.
• Body odor. Although there is interest in using topical hops to reduce body odor, there is insufficient reliable information about the clinical effects of hops for this purpose.
• Insomnia. Taking oral hops extract in combination with valerian root extract seems to be modestly beneficial in patients with insomnia. However, the effect of hops extract when used alone is unclear. Details: In patients with diagnosed sleep disorders, taking hops extract in combination with valerian root for at least 28 days seems to be beneficial. One clinical study in adults with mild insomnia shows that taking two tablets of a combination product containing a total of 83.8 mg hops extract and 374 mg valerian root extract nightly seems to modestly improve subjective sleep measures, including sleep latency, when compared with placebo, after 28 days. However, there was no difference in efficacy between treatment groups after only 14 days (15018). Additionally, a small clinical study in patients with non-organic sleep disorders shows that taking a specific fixed combination product (Ze91019) containing hops extract 120 mg and valerian root extract 500 mg daily for 28 days improves sleep latency when compared with placebo (19413). It is unclear if taking hops and valerian root as a single dose is beneficial in healthy patients. One small clinical study in healthy volunteers with poor sleep shows that taking a specific preparation (Dormeasan, Bioforce AG) containing hops extract 460 mg and valerian root extract 460 mg dissolved in 50 mL of honey water once at night increases total sleep time and time spent in deep sleep when compared with placebo (19418). However, another preliminary clinical study in healthy adults shows that taking a single dose of a specific product (Hova, Zyma S.A.) containing hops extract 200 mg and valerian root extract 400 mg does not improve sleep latency when compared with placebo (6248). Research also shows that taking certain combination products containing hops and at least two other ingredients can improve sleep quality. These combination products have combined hops with lemon balm and valerian (Valerina Natt) (19417); or passionflower and valerian (NSF-3, M/s Tablets India) (88193,89406). However, other combination products have not been beneficial. These have combined hops with soya oil, soya lecithin, and cannabis (Cyclamax, Persee Medica) (55382); or with vitamin B6, zizyphus extract, hydrolyzed milk protein (Lactium), and magnesium oxide (LZ Complex3, Sanofi) (95971).
• Dyspepsia. Although there is interest in using oral hops-derived bitter acids for dyspepsia, there is insufficient reliable information about the clinical effects of hops for this condition.
• Lactation. Although there is interest in using oral hops for increasing lactation, there is insufficient reliable information about the clinical effects of hops for this purpose.
• Menopausal symptoms. It is unclear if oral hops extract is beneficial in patients with menopausal symptoms. Details: Small clinical studies in menopausal patients show that taking a specific hops extract (MenoHop, Biodynamics) 75.1-300 mg standardized to contain 100-200 mcg of 8-prenylnaringenin daily does not improve menopausal symptoms, including hot flashes, after 8-12 weeks of treatment when compared with placebo (55338,55370).
• Overactive bladder. Oral hops extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: An observational study in females with overactive bladder has found that taking a specific combination product (Granu Fink femina, Omega Pharma) containing hops extract 18 mg, sweet sumac bark extract 56 mg, and pumpkin seed oil 227 mg three times daily for 12 weeks decreases the frequency of urination from an average of 0.9 to 0.4 episodes daily and the frequency of leakage when compared with baseline. The study also shows this specific combination product (Granu Fink femina, Omega Pharma) improves quality of life when compared with baseline (103253). The validity of these findings is limited by the lack of a control group. Also, it is unclear if these findings are due to hops extract, other ingredients, or the combination.
• Psychological well-being. It is unclear if drinking non-alcoholic beer containing matured hops bitter acids is beneficial in healthy adults. Details: A clinical study in healthy adults shows that consuming 350 mL of non-alcoholic beer containing matured hops bitter acids 35 mg (Kirin Holdings Co. Ltd) daily for 3 weeks improves mood scores on the Profile of Mood States 2 (POMS2) and Two-dimensional Mood Scale (TDMS) when compared with baseline (107813). The validity of these findings is limited by the lack of a control group.
• Shift work disorder. It is unclear if drinking non-alcoholic beer containing hops is beneficial in patients with shift work disorder. Details: A small open-label clinical study in healthy female nurses working rotating or night shifts shows that drinking 333 mL of non-alcoholic beer containing hops (San Miguel 0% alcohol) at dinner for 2 weeks diminishes sleep latency by about 8 minutes, decreases total activity during the night, and decreases anxiety when compared with baseline. However, it does not appear to increase duration of sleep (55403). The validity of these findings is limited by the lack of a control group and unconfirmed hops content in the beer.
• Vaginal atrophy. Topical hops extract has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: An open-label, multicenter clinical study in postmenopausal patients with vaginal atrophy shows that inserting 2.5 grams of a vaginal gel containing hops extract 1%, hyaluronic acid, liposomes, and vitamin E (Gynomunal Vaginal gel or Esvegyne, Polichem SA) into the vagina daily for one week followed by twice weekly for 11 weeks reduces vaginal dryness, burning, itching, and rash when compared with baseline (55339). The validity of these findings is limited by the lack of a control group. Also, it is unclear if these effects are due to hops, other ingredients, or the combination.
• Venous leg ulcers. Although there is interest in using topical hops for venous leg ulcers, there is insufficient reliable information about the clinical effects of hops for this condition. More evidence is needed to rate hops 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. Two small studies suggest that oral valerian may reduce hot flashes. 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). Both 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.

CNS DEPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of hops with sedative drugs might cause additive sedation.  Details Some animal research shows that hops has sedative effects (55415,55340,105930).

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Hops extract does not seem to affect the metabolism of CYP1A2 substrates.  Details In vitro research suggests that flavonoid constituents of hops inhibit CYP1A2 enzyme activity (10686). However, a pharmacokinetic study in healthy postmenopausal patients shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, does not affect levels of caffeine, a CYP1A2 probe substrate (105954).

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = D Theoretically, hops extract might alter metabolism of CYP3A4 substrates; however, this effect may not be clinically significant.  Details Animal research suggests that specific constituents of hops, called lupulones, can induce hepatic CYP3A4 enzyme activity (55325). However, a pharmacokinetic study in healthy postmenopausal patients with normal metabolism shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, decreases the concentration of alprazolam, a CYP3A4 probe substrate, by 7.6%. This reduction is unlikely to be clinically relevant (105954).

ESTROGENS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of large amounts of hops might interfere with hormone replacement therapy due to competition for estrogen receptors.  Details In vitro research suggests that certain hops constituents can competitively bind to estrogen receptors (3701,10684,10685). However, most hops extracts contain very small amounts of these constituents (105930).

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, hops extract and oil are generally well tolerated when used in food amounts. Hops extract also seems to be well tolerated when used in supplemental amounts.
Most Common Adverse Effects:
Orally: Drowsiness, sedation.

Dermatologic ...Topically, allergic reactions have been reported after contact with the fresh hops plant and plant dust. Contact dermatitis is attributed to the pollen (4,12,105930).

Genitourinary ...Orally, supplements containing hops and soy have been associated with 4 cases of postmenopausal bleeding (55404). It is unclear if this effect is due to hops, soy, or the combination. Also, menstrual disturbances have been reported in female workers harvesting hops (10684,55405).

Neurologic/CNS ...Orally, hops might cause drowsiness and sedation. Historically, hops are thought to have sedative effects, since workers harvesting hops were observed to tire easily after oral contact with hop resin. The European Medicines Agency states that hops may have sedative effects; however, there is a lack of clinical research confirming that hops extract causes drowsiness and sedation (105930).

Pulmonary/Respiratory ...Occupational exposure to dust from hops, usually in combination with dust from other products, is associated with chronic respiratory symptoms such as dry cough, dyspnea, chronic bronchitis, and other occupational respiratory diseases (55333,55414).

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).
