HelloPharmacist Scorecard of Resveratrol 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
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: Polygonum cuspidatum extract, a plant source of resveratrol—a compound used in traditional medicine. The capsule also holds inactive ingredients (rice flour, cellulose, silicon dioxide, and magnesium stearate) that serve as fillers and binders.

Does it work?

No specific claim
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
General wellness

This Hu Zhang product is marketed for general wellness, not a specific health condition, so there's no single claim to grade — see Hu Zhang's own graded uses on its monograph.

Why this rating?
  • The label markets general wellness (“antioxidant support for healthy aging”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.

The evidence for Polygonum cuspidatum extract is insufficient to establish whether it works for the uses it's marketed for. The data we hold does not support reliable claims about hepatitis, rheumatoid arthritis, wound healing, gout, osteoarthritis, or unstable angina.

If you're considering this supplement for one of these conditions, talk it over with your doctor about what's proven and what isn't.

The evidence, ingredient by ingredient Hu Zhang

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Safety data in humans is limited. The supplement's emodin content may cause digestive upset in some people.

Because of gaps in safety information and concern that some compounds might affect the uterus or bowel, the safety facts advise against use in pregnancy and while breastfeeding. If you're pregnant, planning to become pregnant, or nursing, speak with your doctor or pharmacist before taking this product.

Side effects, ingredient by ingredient Hu Zhang

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Hu Zhang.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 827 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Double-check this product with your own doctor or pharmacist if you take blood thinners or antiplatelet drugs (such as warfarin, aspirin, or clopidogrel)—moderate risk of increased bleeding. Also confirm it with medications processed by your liver (including CYP1A2, CYP2C19, CYP3A4, or CYP2E1 substrates), estrogen replacement therapy, or carbamazepine (Tegretol).

The interaction evidence is mostly from lab studies, not human trials, but the risk warrants a conversation before you combine them.

The bottom line

Scorecard at a glanceFully disclosed formula marketed for general wellness rather than one specific gradeable purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Herbal Secrets Resveratrol may appeal to someone looking for a traditional herbal remedy, but the evidence for its effectiveness is not established in the data we hold. The bigger issue is its interaction potential—especially with blood thinners and medications processed by the liver.

If you take any prescription medication, check with your own doctor or pharmacist before starting, and avoid this supplement in pregnancy and while breastfeeding.

Polygonum cuspidatum extract7 drug types · 826 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, hu zhang might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Hu zhang contains the constituent resveratrol. Resveratrol seems to have antiplatelet effects.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, hu zhang might increase levels of drugs metabolized by CYP1A2.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP1A2 enzyme. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, hu zhang might increase levels of drugs metabolized by CYP2C19.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP2C19 enzyme. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, hu zhang might increase levels of drugs metabolized by CYP2E1.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP2E1 enzyme. Also, a pharmacokinetic study shows that taking resveratrol 500 mg daily for 10 days prior to taking a single dose of chlorzoxazone 250 mg increases the maximum concentration of chlorzoxazone by about 54%, the area under the curve of chlorzoxazone by about 72%, and the half-life of chlorzoxazone by about 35%. Chlorzoxazone is used as a probe drug for CYP2E1.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, hu zhang might increase levels of drugs metabolized by CYP3A4.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP3A4 enzyme. However, a clinical study in adults with NAFLD found that adding resveratrol 3000 mg daily for 8 weeks did not necessitate dose adjustments to any established medications metabolized by CYP3A4.

Likelihood Possible Evidence D
Estrogens

Theoretically, hu zhang might competitively inhibit the effects of estrogen replacement therapy.
In vitro research shows that hu zhang might have estrogenic activity.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, hu zhang might increase the effects and adverse effects of carbamazepine.
In animals, blood and tissue levels of carbamazepine were increased when given in combination with hu zhang. It is thought that increased levels of carbamazepine are due to cytochrome P450 3A4 (CYP3A4) inhibition. This interaction has not been reported in humans.

Resveratrol 500 mg by Herbal Secrets: Common Questions

Does Resveratrol 500 mg by Herbal Secrets interact with any medications?
Yes. Based on its ingredients, Resveratrol 500 mg has a known interaction with 826 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Resveratrol 500 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is Polygonum cuspidatum the same as resveratrol?
Polygonum cuspidatum extract is a plant source that contains resveratrol, so it's not exactly the same—it's the plant material that holds that active compound. This product delivers resveratrol 500 mg per capsule.
Can I take this if I'm pregnant or breastfeeding?
No, the safety data advises against it in pregnancy and while breastfeeding. There isn't enough information to know it's safe, and some of its compounds may affect the uterus or bowel. Talk with your doctor or pharmacist about safer options.
What side effects might I notice?
The supplement's emodin content may cause digestive upset. Adverse effects from clinical trials aren't documented in the data we hold, so we can't tell you how common other side effects might be.
Does this really work for arthritis or gout?
The evidence isn't established. We don't have reliable data showing this ingredient works for osteoarthritis, rheumatoid arthritis, gout, or the other conditions it's sometimes marketed for. If you're interested in it for one of these, discuss what's actually proven with your doctor.
Why does it interact with so many medications?
Resveratrol can inhibit enzymes in your liver that break down medications. When those enzymes slow down, drugs can accumulate in your bloodstream and become stronger or cause side effects. That single mechanism affects a wide range of medications your liver processes.
