HelloPharmacist Scorecard of Resveratrol Japanese Knotweed, 75 mg by Solaray
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 has 4 active ingredients: red wine extract (providing resveratrol), Japanese knotweed root and rhizome extract, grape, and a polyphenol blend. Resveratrol is the key compound—a plant antioxidant that's the main reason you're taking this.
Japanese knotweed (also called hu zhang) is a traditional herb that also contains resveratrol and polyphenols. The other ingredients round out the polyphenol content.
The capsule itself and the filler ingredients (cellulose, silica, maltodextrin, magnesium stearate) are inactive.
Does it work?
Moderate evidence
For resveratrol, the data we hold shows it's possibly effective for obesity and allergic rhinitis (hay fever), but possibly ineffective for cardiovascular disease and high cholesterol. For Japanese knotweed, we don't have enough reliable evidence to rate its use for hepatitis, rheumatoid arthritis, wound healing, gout, osteoarthritis, or unstable angina.
If you're taking this for one of those reasons, talk to your doctor or pharmacist about whether the evidence supports it for you.
How safe is it?
Well-documented data
Resveratrol is generally well tolerated at typical supplement doses. Higher doses may cause digestive upset, including diarrhea, loose stools, and gastrointestinal discomfort.
Rare adverse effects reported in trials include headache, fatigue, and skin rash—the rash resolved after stopping the supplement. There isn't enough safety data on concentrated resveratrol supplements during pregnancy, so avoid it if you're pregnant.
Don't use this while breastfeeding either—the safety information isn't there. Japanese knotweed is traditionally used but human safety data for supplements is limited; its emodin content may cause digestive upset, and certain compounds may affect the uterus or bowel, so it's best avoided in pregnancy and lactation.
Meds to double-check
Moderate interaction found
Before taking this product, check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (like warfarin, aspirin, clopidogrel)—resveratrol increases bleeding risk. Also clear it if you take seizure medications (especially carbamazepine), hormone replacement therapy, or any drug metabolized by your liver's CYP2C19, CYP1A2, CYP3A4, or CYP2E1 enzymes—resveratrol may raise their blood levels.
Use the checker on this page to search your exact medications.
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.
This resveratrol product might help with obesity or hay fever, though the evidence is modest. If you take blood thinners, antiplatelet drugs, seizure medications, hormones, or any drug your liver metabolizes heavily, you'll need to check with your doctor or pharmacist before starting—resveratrol can affect how your body handles many medications.
If you're pregnant, breastfeeding, or have digestive sensitivity, talk it over with your healthcare provider first.

Resveratrol Japanese Knotweed, 75 mg by Solaray Drug Interactions
HelloPharmacist Interaction Report
Solaray's Resveratrol Japanese Knotweed contains resveratrol (from red wine extract and Japanese knotweed) that interacts with several medication types.
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin, aspirin, and clopidogrel)—resveratrol may increase bleeding risk by adding its own antiplatelet effects to theirs.
Read the full breakdown — every affected drug type, severity by severity
Resveratrol can also inhibit liver enzymes (CYP2C19, CYP1A2, CYP3A4, and CYP2E1) that break down many medications, theoretically raising their blood levels. In vitro (lab) studies show this inhibition, but human trials are limited—notably, a study at 3000 mg daily for 8 weeks found no dose adjustment needed for CYP3A4 substrates.
The product also contains Japanese knotweed, which carries the same enzyme interactions through its resveratrol content, plus a theoretical estrogenic effect that could interfere with hormone replacement therapy and a Minor interaction with the seizure medication carbamazepine (Tegretol).
We hold no interaction data for the polyphenol blends listed on the label. Altogether, these interactions span 827 individual medications.

For each ingredient in Resveratrol Japanese Knotweed, 75 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Grape
Anticoagulant/Antiplatelet Drugs
Theoretically, grape extracts may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that grape extracts might decrease platelet aggregation.
Cyclosporine (Neoral, Sandimmune)
Ingesting grape juice with cyclosporine can reduce cyclosporine absorption.
A small pharmacokinetic study in healthy young adults shows that intake of purple grape juice 200 mL along with cyclosporine can decrease the absorption of cyclosporine by up to 30% when compared with water. Separate doses of grape juice and cyclosporine by at least 2 hours to avoid this interaction.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, grape juice might reduce the levels of CYP1A2 substrates.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of CYP1A2.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, grape seed extract may increase the levels of CYP2D6 substrates.
In vitro evidence suggests that grape seed extract might inhibit CYP2D6 enzymes. However, this interaction has not been reported in humans.
Cytochrome P450 2E1 (Cyp2E1) Substrates
Theoretically, grape seed extract might increase the levels of CYP2E1 substrates.
In vitro and animal research suggests that grape seed proanthocyanidin extract inhibits CYP2E1 enzymes. However, this interaction has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
It is unclear if grape seed extract inhibits or induces CYP3A4; research is conflicting.
In vitro evidence suggests that grape seed extract might inhibit CYP3A4 enzymes. However, evidence from animal research shows that grape seed extract may induce CYP3A4 in the liver. So far, these interactions have not been reported in humans.
Midazolam (Versed)
Theoretically, long-term intake of grape seed extract might decrease the effects of midazolam.
Animal research shows that subchronic ingestions of grape seed extract can increase the elimination of intravenous midazolam by increasing hepatic CYP3A4 activity. Single doses of grape seed extract do not appear to affect midazolam elimination.
Phenacetin
Grape juice might decrease phenacetin absorption.
A small pharmacokinetic study in healthy adults shows that ingestion of 200 mL of grape juice decreases phenacetin plasma levels. This is thought to be due to induction of cytochrome P450 1A2 (CYP1A2).
Cytochrome P450 2C9 (Cyp2C9) Substrates
It is unclear if grape juice or grape seed extract inhibits CYP2C9; research is conflicting.
In vitro evidence shows that grape seed extract or grape juice might inhibit CYP2C9 enzymes. However, a small pharmacokinetic study in healthy adults shows that drinking 8 ounces of grape juice once does not affect the clearance of flurbiprofen, a probe-drug for CYP2C9 metabolism. The effects of continued grape juice consumption are unclear.
Japanese Knotweed (Polygonum cuspidatum) (root/rhizome extract)
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.
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.
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.
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.
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.
Estrogens
Theoretically, hu zhang might competitively inhibit the effects of estrogen replacement therapy.
In vitro research shows that hu zhang might have estrogenic activity.
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.
Red Wine extract
Anticoagulant/Antiplatelet Drugs
Resveratrol may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Resveratrol seems to have antiplatelet effects.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, resveratrol might increase levels of drugs metabolized by CYP1A2.
In vitro research shows that resveratrol can inhibit CYP1A2 enzymes. However, this interaction has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, resveratrol might increase levels of drugs metabolized by CYP2C19.
In vitro research shows that resveratrol can inhibit CYP2C19 enzymes. However, this interaction has not been reported in humans.
Cytochrome P450 2E1 (Cyp2E1) Substrates
Resveratrol might increase levels of drugs metabolized by CYP2E1.
In vitro research suggests that resveratrol inhibits CYP2E1 isoenzyme. 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.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, resveratrol might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that resveratrol can inhibit the CYP3A4 enzyme. However, clinical research shows that taking resveratrol 3000 mg daily for 8 weeks does not necessitate dose adjustments to medications metabolized by CYP3A4.
