HelloPharmacist Scorecard of Dioscorea Capsules by Genestra Brands

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: wild yam root (also called Dioscorea). The capsule itself is made from hypromellose and cellulose, which are inactive ingredients that help form and hold the supplement.

Does it work?

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
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: menopausal symptoms and hormone balance.
  • We looked for evidence on: Menopausal symptoms, Postmenopausal conditions, Dysmenorrhea, Premenstrual syndrome (PMS), hormonal balance, menstrual health.
  • The closest evidence on file: Wild Yam is rated "Possibly Ineffective" for Menopausal symptoms (Natural Medicines).
  • Also on file: Wild Yam is rated "Insufficient Reliable Evidence To Rate" for Postmenopausal conditions, Premenstrual syndrome (PMS), Dysmenorrhea.

The evidence for wild yam is mixed and mostly limited. For menopausal symptoms — a common reason people take it — the data shows it's possibly ineffective.

For gallbladder disease, sexual dysfunction, painful periods, and infertility, there isn't enough reliable evidence yet to say whether it works or not.

The evidence, ingredient by ingredient Wild Yam

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 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.

Wild yam is generally well tolerated when taken by mouth, and short-term use in healthy adults appears to be fine. The most common side effects are fever, headache, upset stomach, and vomiting, with headache and fever especially likely at higher doses.

Rarely, anaphylaxis (a severe allergic reaction) has been reported. Long-term safety hasn't been well studied, so we don't have solid data on what happens with extended use.

The safety data advises against using wild yam during pregnancy and while breastfeeding — there isn't enough information to know it's safe in those situations. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning to become pregnant, or nursing.

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 — Wild Yam.
  • The most serious interaction on file is rated Moderate.
  • For scale: 41 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.

Check before starting if you take any estrogen-based medication, including birth control pills and hormone replacement therapy. Wild yam could theoretically change how these drugs work.

The bottom line

Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Wild yam may be worth considering if you're exploring options for menopausal symptoms, though the evidence suggests it probably won't help. The main caution is its interaction with estrogen-containing medications — if you take any form of hormone therapy, clear this with your doctor or pharmacist first.

It's generally well tolerated for short-term use, but we don't know much about long-term safety, and it's not recommended in pregnancy or while breastfeeding.

Dioscorea Capsules by Genestra Brands: Common Questions

Does Dioscorea Capsules by Genestra Brands interact with any medications?
Yes. Based on its ingredients, Dioscorea Capsules has a known interaction with 41 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Dioscorea Capsules 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.
Will wild yam help with hot flashes and other menopausal symptoms?
The research suggests it probably won't. For menopausal symptoms, wild yam is rated possibly ineffective, meaning the evidence doesn't support its use for that purpose.
What side effects should I watch for?
Most people who take wild yam by mouth tolerate it well. The common side effects are fever, headache, upset stomach, and vomiting — especially if you take higher doses. Rarely, severe allergic reactions (anaphylaxis) have been reported.
Can I take this while pregnant or breastfeeding?
No. The safety data isn't there to support use during pregnancy or while nursing. Talk with your doctor or pharmacist for personalized advice if you're in either situation.
Is wild yam safe to take long-term?
Short-term use in healthy adults appears fine, but we don't have good data on what happens over months or years. If you're thinking about taking it long-term, discuss that with your doctor or pharmacist.
What does wild yam do in the body?
Wild yam shows both estrogenic and anti-estrogenic effects in lab studies, meaning it could mimic or block estrogen in your body. That's why it's important to check with your doctor if you take hormone-based medications.
