HelloPharmacist Scorecard of Valerian Root by Alvita
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
Alvita Valerian Root is a single-ingredient product — just valerian, the root of a perennial plant used traditionally for sleep and relaxation. One tea bag gives you the herb steeped in hot water.
There are no inactive fillers or binders listed.
Does it work?
Moderate evidence
Valerian is possibly effective for insomnia — that's the one condition with enough evidence to suggest it may help. For restless legs syndrome, pre-procedural anxiety, stress, and dysmenorrhea (period pain), the evidence isn't established enough in our data to say whether it works or not.
If you're considering valerian for one of those other uses, that's a conversation worth having with your pharmacist or doctor.
How safe is it?
Well-documented data
Valerian is generally well tolerated short-term, but long-term safety hasn't been well studied, so caution is warranted if you're thinking of using it for months on end. Common side effects include dizziness, drowsiness, mental slowness, headache, upset stomach, and vivid dreams.
If you use it regularly and then stop suddenly, you might experience withdrawal symptoms — restlessness, anxiety, irritability, insomnia, or rapid heartbeat. Taper your dose slowly after extended use.
Valerian is not recommended during pregnancy or while breastfeeding due to lack of safety data. There have also been rare case reports of liver damage linked to valerian-containing products, though most involved multi-ingredient formulas.
Chronic use and abrupt cessation have occasionally been associated with more serious effects like agitation, insomnia, and hallucinations.
Meds to double-check
Moderate interaction found
Double-check valerian if you take CNS depressants (sedatives, sleep aids, some pain meds), alprazolam or other anxiety medications, or drink alcohol regularly. Also ask your pharmacist about glucuronidated drugs — a specific group your liver processes — as valerian may weakly affect how they're cleared.
These are Moderate-severity interactions.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Valerian may help with insomnia if you're looking for a plant-based option. But it's a sedative, so you need to be careful if you take other sleep aids, anxiety medications, or anything that makes you drowsy — talk to your pharmacist before combining.
Avoid it in pregnancy and while breastfeeding, and don't stop suddenly after regular use.

Formula
Star-K (Kosher)
Valerian Root Valerian (Valeriana officinalis), has been used traditionally to support restful sleep for hundreds of years. It has been referenced in many pharmacopeias for its relaxing and calming qualities. Today, valerian remains one of the most popular herbs used to support a good night's rest.
Alvita Valerian Root Tea is made with premium-quality, organic valerian root, and possesses a distinctly penetrating aroma and a flavor that is initially sweet, with a faint bitter finish.
General Statements
The Alvita Story… In 1922, a new era for tea consumption began in America. The herb alfalfa, long known for its beneficial nutrients, was packaged in tea bags and sold to an emerging health food market. This product became known as Alvita and set the standard for future herbal teas. Today, Alvita represents more than forty single-ingredient teas, each one uniquely distinct, just like the individuals who drink them.
Herbs are gifts from the earth. Alvita takes its stewardship seriously by offering carefully harvested teas in earth-friendly packaging. Our beautifully illustrated boxes are made using recycled paperboard and our English, pillow style tea bags are oxygen bleached, not chlorine treated. You won’t find a better product, with a cleaner package… anywhere. Alvita… brewed with confidence, steeped in tradition.

Valerian monograph & interactionsValerian Root by Alvita Drug Interactions
HelloPharmacist Interaction Report
Alvita Valerian Root does interact with several medication types.
The most serious concern is with CNS depressants — drugs that slow down your central nervous system, like sedatives, sleep aids, and some pain medications. Valerian can add to their drowsy effect, and in theory might cause excessive sedation.
Read the full breakdown — every affected drug type, severity by severity
Valerian also interacts moderately with glucuronidated drugs (medications your liver processes through a particular pathway), alprazolam (Xanax), and alcohol. With alprazolam, you're looking at additive sedation; with alcohol, the same.
Valerian may weakly slow how your liver clears certain glucuronidated drugs, though the clinical impact is uncertain.
On the lighter side, valerian appears to have only minor or no clinically relevant effects on drugs metabolized by the CYP2D6 and CYP3A4 enzymes — two major liver pathways. Altogether, these interactions span 891 individual medications.

For each ingredient in Valerian Root with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Valerian
Alcohol (Ethanol)
Valerian can have additive sedative effects when used concomitantly with alcohol.
Valerian has sedative effects. 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. 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.
Alprazolam (Xanax)
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.
Valerian has sedative effects. 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). Despite being statistically significant, this increase is not likely to be clinically significant.
Cns Depressants
Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Theoretically, concomitant use of valerian and drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects.
Glucuronidated Drugs
Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.
In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.
Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme. 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.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.
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. 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. However, this mild inhibition is unlikely to be clinically relevant.
