HelloPharmacist Scorecard of Valerian Root 500 mg by Herbal Secrets
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
This product contains one active ingredient: valerian root powder at 500 mg per capsule. Valerian is a dried plant material traditionally used to promote relaxation and sleep.
The capsule is made from gelatin, and the powder includes silicon dioxide and magnesium stearate as inactive ingredients to help with flow and shelf life.
Does it work?
Moderate evidence
Valerian is possibly effective for insomnia — the main use people reach for it for. For other conditions listed on the label, the evidence isn't strong enough to establish whether it works: we don't have solid data yet on whether it helps restless legs syndrome, anxiety before procedures, everyday stress, or menstrual cramps.
If sleep support is your goal, valerian may be worth trying; for other uses, talk with your doctor about whether there's better evidence for other options.
How safe is it?
Well-documented data
Valerian is generally well tolerated short-term. The most common side effects are dizziness, drowsiness, mental slowness, headache, stomach upset, and vivid or unusual dreams.
A small number of people report restlessness or excitability instead of calm. If you take it regularly and then stop suddenly, you might experience withdrawal symptoms like anxiety, irritability, faster heart rate, or insomnia — so taper your dose slowly after extended use rather than stopping all at once.
Rare cases of liver problems have been reported with multi-ingredient products containing valerian, though a direct link hasn't been proven. The product label advises against use during pregnancy and breastfeeding because safety hasn't been established in those settings.
If you're pregnant or nursing and considering this supplement, talk with your doctor or pharmacist before taking it.
Meds to double-check
Moderate interaction found
Before you take this product, check your medications for CNS depressants (sedatives, sleep aids, opioids, anti-anxiety drugs) and any medications processed through glucuronidation — both carry Moderate interaction risk. Also avoid alcohol while using valerian.
Minor interactions are possible with drugs that rely on CYP2D6 or CYP3A4 liver enzymes, but clinical evidence suggests these are unlikely to cause problems in real life. Your doctor or pharmacist can review your full medication list.
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 Root 500 mg is worth considering if you're looking for a natural sleep aid and insomnia is your main concern — evidence supports that it may help. However, it's a sedating herb: avoid it with alcohol and any sleep or anti-anxiety medications, and let your doctor or pharmacist know you're taking it so they can check for conflicts with your other drugs.
Taper slowly if you've been using it regularly and decide to stop.

Valerian Root 500 mg by Herbal Secrets Drug Interactions
HelloPharmacist Interaction Report
Herbal Secrets Valerian Root 500 mg interacts with several medication types through its valerian root powder content.
The most serious concerns are additive sedation with CNS depressants (drugs that slow brain activity like sedatives, sleeping pills, and anesthetics) and a possible weak effect on drugs processed through glucuronidation pathways — both rated Moderate severity.
Read the full breakdown — every affected drug type, severity by severity
Valerian can noticeably boost drowsiness, dizziness, and mental slowness when combined with any CNS depressant. This includes alprazolam (Xanax) and other anti-anxiety medications, sleep aids, opioids, and alcohol.
The product warns to avoid alcohol in particular and to be cautious with any prescription sedative.
Valerian may also weakly interfere with how your body clears drugs metabolized by glucuronidation (a liver-processing step), potentially raising levels of certain medications. Minor interactions are documented with drugs that rely on two liver enzymes (CYP2D6 and CYP3A4), but clinical evidence suggests these are unlikely to cause real-world problems.
Altogether, these interactions span 903 individual medications. Before you start this product, use the medication checker below to see if any of your prescriptions are on the list — and talk with your doctor or pharmacist about timing and dosing if you take sedating drugs or medications processed by your liver.

For each ingredient in Valerian Root 500 mg 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 powder
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.
