HelloPharmacist Scorecard of Wild Yam & Chaste Tree by Nature's Sunshine

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 3 active ingredients.

This product contains 3 active ingredients. Chaste tree berry extract (also called vitex) and wild yam root and root extract are the two named actives; they're combined with a proprietary blend you'll see listed on the label but whose exact composition we can't break down for you.

The inactive ingredients are cellulose, a capsule, magnesium stearate, and stearic acid — common fillers and binders.

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: herbal support for women during menopause.
  • We looked for evidence on: Menopausal symptoms, hot flashes, night sweats, hormonal balance.
  • The closest evidence on file: Wild Yam is rated "Possibly Ineffective" for Menopausal symptoms (Natural Medicines).
  • Also on file: Vitex Agnus-castus is rated "Insufficient Reliable Evidence To Rate" for Menopausal symptoms.

Chaste tree berry extract is possibly effective for premenstrual syndrome (PMS) and breast tenderness (mastalgia), based on available evidence. For aging skin, anxiety, and premenstrual dysphoric disorder (PMDD), the evidence isn't established in our data — we simply don't have enough reliable information to rate it one way or the other.

Wild yam appears possibly ineffective for menopausal symptoms. For gallbladder disease, sexual dysfunction, menstrual cramps, and infertility, the evidence we hold on wild yam is insufficient to say whether it works.

The evidence, ingredient by ingredient Vitex Agnus-castus 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both chaste tree and wild yam are generally well tolerated in the short term. Chaste tree may cause diarrhea, fatigue, headache, insomnia, irregular menstruation, nausea, stomach pain, vomiting, and skin irritation; irregular or prolonged bleeding has also been reported.

Wild yam commonly causes fever, headache, upset stomach, and vomiting, and rarely can trigger anaphylaxis (a severe allergic reaction). Because chaste tree affects hormones, use it only under professional guidance.

The facts advise against chaste tree during pregnancy and breastfeeding due to possible hormonal effects and limited safety data. For wild yam, there isn't enough safety information — avoid it during pregnancy and breastfeeding and talk with your doctor or pharmacist about its use.

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?
  • 2 of the 2 matched ingredients can interact with medications — Vitex Agnus-castus, Wild Yam.
  • The most serious interaction on file is rated Moderate.
  • For scale: 121 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 taking this product, double-check with your doctor or pharmacist if you use any estrogen-based medications (birth control pills, hormone replacement therapy), antipsychotic drugs, dopamine agonists, or metoclopramide (Reglan). All are listed as Moderate-severity interactions with the chaste tree or wild yam in this product.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with PMS and breast tenderness if chaste tree is your main interest. If you take birth control, hormone therapy, antipsychotic or anti-nausea medications, or dopamine-boosting drugs, you'll want to check with your doctor or pharmacist first — the interactions are real and could affect how your medications work.

Avoid it during pregnancy and breastfeeding. Run your full medication list through the tool on this page before you start.

Wild Yam & Chaste Tree by Nature's Sunshine: Common Questions

Does Wild Yam & Chaste Tree by Nature's Sunshine interact with any medications?
Yes. Based on its ingredients, Wild Yam & Chaste Tree has a known interaction with 121 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wild Yam & Chaste Tree contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this with my birth control pills?
Not without checking first. Chaste tree and wild yam both have moderate interactions with contraceptive drugs — they may interfere with how well your birth control works. Talk to your doctor or pharmacist before starting this product.
Is it safe to use while I'm pregnant?
The facts advise against chaste tree during pregnancy due to possible hormonal effects and limited safety data. Wild yam also doesn't have enough safety information, so avoid it too. Talk with your doctor or pharmacist if you're pregnant or planning to be.
What side effects might I experience?
Chaste tree commonly causes irregular menstruation, nausea, headache, fatigue, diarrhea, stomach pain, and vomiting; skin irritation and changes in menstrual bleeding have also been reported. Wild yam may bring on fever, headache, upset stomach, and vomiting. Rarely, wild yam can cause anaphylaxis (a severe allergic reaction).
Does this actually work for PMS?
Chaste tree berry extract is possibly effective for PMS and breast tenderness based on available evidence. The evidence for wild yam on other conditions in this product — menopausal symptoms, sexual dysfunction, menstrual cramps, infertility — is either insufficient to rate or suggests it doesn't work (menopausal symptoms).
Can I breastfeed while taking this?
No. Chaste tree may influence milk-related hormones and its safety during breastfeeding is unclear, so it's not recommended. Wild yam also doesn't have enough safety data. Talk to your doctor or pharmacist for personalized advice.
What is the proprietary blend and why can't you tell me what's in it?
The label lists a proprietary blend, which means the manufacturer keeps the exact composition and amounts private — we have no data on what's actually in it, so we can't check it for interactions. Ask the maker directly if you want those details, or ask your pharmacist.
