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 tuber extract (dry form). The liquid also includes glycerin and water as inactive ingredients to deliver the extract.

Does it work?

Leans against
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: support for menopausal symptoms and menstrual health.
  • We looked for evidence on: Menopausal symptoms, Dysmenorrhea, Premenstrual syndrome (PMS), Postmenopausal conditions, Hormone balance, Menstrual cramping.
  • 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. For menopausal symptoms, the data we have rates it as possibly ineffective.

For gallbladder disease, sexual dysfunction, difficult periods, and infertility, there isn't enough reliable evidence yet to say whether it works or doesn't. If you're considering it for one of these uses, that's worth talking over with your doctor.

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 short-term 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.

Anaphylaxis is rare but has been reported. There isn't enough safety data to recommend wild yam during pregnancy or while breastfeeding, so those are situations to avoid it or discuss it with your doctor or pharmacist first.

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.

Before you start this product, check with your doctor or pharmacist if you take any estrogen-based medications—including birth control pills, hormone replacement therapy, or estrogen patches. Wild yam may interfere with 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 Alcohol Free is a single-ingredient extract that's generally well tolerated for short-term use, but the evidence it works for common uses like menopausal symptoms is weak or absent. The main caution is its potential to interfere with estrogen medications.

If you're on any hormone therapy or birth control, or if you're pregnant, nursing, or planning to be, check with your own doctor or pharmacist before taking it.

Wild Yam Alcohol Free by Hawaii Pharm: Common Questions

Does Wild Yam Alcohol Free by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Wild Yam Alcohol Free 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 Alcohol Free 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.
Does wild yam help with hot flashes and night sweats?
The evidence suggests it likely doesn't work for menopausal symptoms. If you're dealing with hot flashes or night sweats, your doctor can discuss other options that have stronger evidence behind them.
What side effects might I notice?
Most people who take wild yam orally tolerate it well. The most common side effects are fever, headache, upset stomach, and vomiting—especially if you take higher doses. Anaphylaxis is very rare but has been reported.
Is it safe to take while pregnant or breastfeeding?
No—there isn't enough safety data. The data we have advises against it during pregnancy and while breastfeeding. Talk with your doctor or pharmacist if you're pregnant, nursing, or planning to be.
Can I take this long-term?
Short-term use in healthy adults is likely fine, but we don't have good long-term safety data for wild yam. If you're thinking of taking it regularly for weeks or months, check with your doctor or pharmacist first.
Why is there a warning about estrogen medications?
Wild yam has both estrogenic and anti-estrogenic properties—meaning it can act like estrogen in some ways and block it in others. It might interfere with birth control pills or hormone replacement therapy, making them less effective or changing how they work.
