If you take a statin, the safest answer is to check every herb, concentrated tea extract, vitamin, and supplement with your pharmacist or clinician before you add it. Green tea extract and soy isoflavone extract are two plant products specifically being studied alongside simvastatin and rosuvastatin, so they belong on that conversation list.

Why herbs and statins need a personal check
Statins are medicines used to lower cholesterol and reduce the risk of heart attack and stroke. Network of Care’s statin guide lists atorvastatin, pravastatin, and simvastatin as examples and recommends telling your pharmacist or doctor about all medicines, vitamins, herbs, and supplements you use.
An interaction is not simply a matter of whether an herb is “good” or “bad.” It can depend on the specific statin, the form of the plant product, the amount, and your other medicines. A tea bag, a capsule, and a concentrated extract are not automatically the same thing.
Which herbs should you put on the statin checklist?
Start with every product you use regularly, especially anything sold as an extract, powder, capsule, tincture, gummy, or concentrated drink. The two plant extracts named in current statin-interaction research are green tea extract and soy isoflavone extract.
| Plant product | Why it belongs on your list | What to ask |
|---|---|---|
| Green tea extract | It is being studied with simvastatin and rosuvastatin. | “Is this form and amount suitable with my statin?” |
| Soy isoflavone extract | It is also being studied with simvastatin and rosuvastatin. | “Does this fit with my medicines and health history?” |
| Any herb blend or supplement | Multi-ingredient labels can make an interaction check harder. | “Can we review this full label together?” |
The registered herb-and-statin trial compares simvastatin and rosuvastatin with green tea extract and soy isoflavones in healthy adults. It is a completed study registration, not a set of results. That distinction matters: it tells you these extracts are worth naming at your visit, without turning the study listing into a yes-or-no answer for your own prescription.
Can herbs help with cholesterol or high blood pressure?
Plants have a long place in food traditions and herbal practice. Herbal teas have been used in Chinese medicine for centuries, as described in this PubMed history of medicinal teas. Tradition can help explain why a plant is popular, but it does not replace an interaction review when you take a prescription medicine.
For high blood pressure, a 2024 systematic review and meta-analysis gathered 25 randomized trials involving 1,996 people who used herbs alongside blood-pressure medicines. The pooled results favored the herb-plus-medicine groups for systolic blood pressure and triglycerides, while the review found no significant overall effect for diastolic pressure, total cholesterol, HDL, or LDL. The studies varied greatly from one another, so this is a useful conversation starter, not a reason to layer herbs onto a medicine plan on your own.
What about herbs if you also take blood-pressure medicine?
The same careful approach applies when a statin is part of a larger medicine routine. Bring the name of each prescription, the dose on its label, and the full ingredient panel for every herbal product. Your pharmacist or clinician can check the combination rather than guessing from the front of a bottle.

What should you ask before trying a heart-health tea or supplement?
A drink can be enjoyable, but there is no single “heart-calming” tea that suits every medicine list. A good question is more useful than a trending claim: “Is this ordinary tea, or is it a concentrated extract?” Then ask whether the exact product fits with your statin and any blood-pressure medicine.
- Write down the exact name of your statin.
- Take photos of the front and Supplement Facts panel for each herb or tea product.
- Include extracts, blends, powders, gummies, vitamins, and energy drinks.
- Ask a pharmacist or clinician to review the complete list before you add a new product.
- Use the product label, not just the marketing name, when you ask.
