HelloPharmacist Scorecard of Valerian Root by TerraVita
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
TerraVita Valerian Root Liquid Extract contains one active ingredient: valerian root provided as a glycerite liquid extract. The only other ingredient is glycerin, which is the liquid base.
Does it work?
Moderate evidence
Valerian has been rated possibly effective for insomnia—the most studied use. For other conditions like restless legs syndrome, pre-procedural anxiety, stress, and dysmenorrhea, the evidence we hold isn't established enough to rate.
If you're considering this for sleep, it may help, but talk with your pharmacist about how long you might need to take it and what to expect.
How safe is it?
Well-documented data
Valerian is generally well tolerated short-term, though long-term safety hasn't been well studied. Common side effects include dizziness, drowsiness, mental slowness, headache, stomach upset, and vivid dreams.
If you take it for a while and then stop abruptly, you may experience withdrawal symptoms like anxiety, irritability, insomnia, fast heartbeat, or agitation—so it's best to taper your dose slowly after extended use. Rare serious side effects including liver injury have been reported, though most often in multi-ingredient products.
The safety data advises against use during pregnancy and while breastfeeding.
Meds to double-check
Moderate interaction found
Before you start, double-check any CNS depressants (sedatives, sleeping pills, anti-anxiety medications), alprazolam (Xanax) specifically, alcohol, and medications processed through glucuronidation—a large group that includes certain pain relievers and antibiotics. Even minor-severity interactions with CYP2D6 and CYP3A4 substrates are documented, so run your exact medications through the checker on this page.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Valerian may help with insomnia, but it's a sedative and will make you drowsy—don't plan to drive or do anything that needs sharp focus. If you take any sleeping pills, anxiety medications, or drink alcohol regularly, check with your pharmacist first.
Pregnant or nursing? This one's not recommended.
And if you use it long-term, plan to taper it slowly rather than stop cold turkey.

Valerian Root by TerraVita Drug Interactions
HelloPharmacist Interaction Report
TerraVita Valerian Root Liquid Extract does interact with several medication types.
The most serious concern is with CNS depressants—drugs like sedatives, sleeping pills, and anxiety medications—where valerian can add to their drowsy, sedating effects. This is a moderate-severity interaction that can lead to excessive sleepiness, mental slowness, and dizziness.
Read the full breakdown — every affected drug type, severity by severity
Valerian also has moderate interactions with alcohol (ethanol), which carries the same additive sedative risk, and with alprazolam (Xanax), a common anti-anxiety medication, where the combination can increase both sedation and alprazolam levels in your body. Additionally, valerian may moderately affect how your body processes glucuronidated drugs—a large group of medications that includes certain pain relievers, antibiotics, and hormonal drugs—by weakly slowing their clearance and raising their levels.
On the milder side, valerian appears to have only minor or no significant effects on medications broken down by the CYP2D6 and CYP3A4 liver enzymes, so those interactions are less of a concern. 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 Root Glycerite Liquid Extract
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.
