HelloPharmacist Scorecard of Wild Yam by Herb Pharm

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.

From our pharmacy team — supplement deep dive

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 rhizome extract. The extract is suspended in cane alcohol and distilled water.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Wild Yam's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: system restoration and musculoskeletal support.
  • We looked for evidence on: Dysmenorrhea, Menopausal symptoms, Postmenopausal conditions, Premenstrual syndrome (PMS), Rheumatoid arthritis (RA), joint health — and 2 related terms.
  • 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), Rheumatoid arthritis (RA), Dysmenorrhea.

The evidence for wild yam is mixed and sparse. For menopausal symptoms, it's rated possibly ineffective — meaning the research doesn't support it working for that use.

For gallbladder disease, sexual dysfunction, period pain, and infertility, there isn't enough reliable evidence in our data to say whether it works or doesn't.

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 for short-term use in healthy adults, though long-term safety hasn't been well studied. The most common side effects are fever, headache, upset stomach, and vomiting — especially at higher doses.

A rare serious reaction, anaphylaxis, has been reported. The safety data advises against use during pregnancy and while breastfeeding.

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 any estrogen-based medications (Moderate severity) — including hormone replacement therapy and hormonal birth control — before you start wild yam. The product might increase or decrease how estrogen works in your body.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Wild yam may appeal to you if you're exploring options for menopausal or gynecological concerns, but the evidence for most uses is thin. If you take any estrogen-based medication or hormone therapy, check with us first — this product can potentially interfere.

Talk to your pharmacist about whether it fits your situation.

Wild Yam by Herb Pharm: Common Questions

Does Wild Yam by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Wild Yam 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?
Wild Yam 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?
The research doesn't support wild yam for menopausal symptoms — it's rated possibly ineffective for that use. If you're dealing with hot flashes, talk to your pharmacist about options with stronger evidence behind them.
What are the most common side effects?
Fever, headache, upset stomach, and vomiting are the side effects people report most often, especially at higher doses. Most folks tolerate it fine for short-term use, but long-term safety hasn't been well studied.
Is it safe to take while pregnant or breastfeeding?
The safety data advises against wild yam during pregnancy and while breastfeeding — there isn't enough data to know it's safe. Talk with your doctor or pharmacist about what's right for you.
Can I take this with my birth control?
Wild yam can potentially interfere with estrogen-based medications, including hormonal birth control. Check with us using the search tool on this page before you start, so we can see your exact medication.
What does wild yam do in the body?
The extract shows both estrogenic and anti-estrogenic effects in laboratory tests — meaning it may act like estrogen in some ways and against it in others. That's why it can theoretically interfere with hormone therapy.
