Drug & supplement interaction

Wild Yam + Danazol

Danazol brand names: Cyclomen, Danocrine.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Wild Yam and Danazol in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Wild Yam and Danazol

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Danazol and Wild Yam in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Wild Yam safety at a glance

Wild Yam overall Use caution Likely fine for short-term use in healthy adults, but long-term safety is not well studied.
Pregnancy Avoid Not enough safety data; avoid during pregnancy.
Breastfeeding Avoid Not enough safety data; avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Danazol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Danazol is filed under 3 classifications — cytochrome p450 3a4 (cyp3a4) inhibitors, photosensitizing drugs, oral drugs. Wild Yam has documented interactions with 1 drug class — the most serious being estrogens (moderate) — and none of Danazol’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Wild Yam and Danazol May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

Reported for Wild Yam but not commonly for Danazol: stomach upset, a severe allergic reaction, loss of vision and blood clots.

Effects for Danazol come from the ADVERSE REACTIONS section of its FDA label; effects for Wild Yam come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 2,804 voluntary FDA FAERS reports for Danazol that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Overlapping uses

What Danazol Is Prescribed For, and What Wild Yam Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Danazol is a prescription medicine with approved uses on its FDA label. Wild Yam is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Danazol is prescribed for: Danazol capsules are used to treat endometriosis — a condition where tissue similar to the uterine lining grows outside the uterus, causing pain and sometimes infertility. It works by suppressing the hormonal cycle that drives this abnormal tissue growth. Danazol capsules are also used to prevent attacks of hereditary angioedema — a genetic condition that causes episodes of severe swelling in the skin, abdomen, face, and airway. All types of attacks (cutaneous, abdominal, and laryngeal) can be prevented with danazol.

Wild Yam has been studied for:

  • Infertility studied, not established Wild Yam has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Wild Yam for infertility

    Although there is interest in using oral or topical wild yam for infertility, there is insufficient reliable information about the clinical effects of wild yam for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Danazol on your own; if you are taking Wild Yam for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Everything else you take

See Every Supplement That Interacts With Danazol

This page covers Wild Yam only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Danazol page lists 50 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), Alfalfa (moderate), Angelica Archangelica (moderate) and Arrach (moderate).

By severity: 1 major · 38 moderate · 11 minor.

From our pharmacist’s overview on the Danazol page

“Activated charcoal carries the only major rating on danazol's list. Danazol treats endometriosis, fibrocystic breast disease, and hereditary angioedema, conditions where a weakened dose has real consequences, and charcoal can soak up the drug in the gut before it reaches the blood.”

About Wild Yam

What is Wild Yam?

  • Menopausal symptoms
  • Menstrual cramps
  • Hormone balance (popular belief)
  • Digestive cramps
  • Joint and muscle discomfort

Wild yam is a root traditionally used for menopausal symptoms, cramps, and as a so-called 'natural' hormone supplement, but solid human evidence for these uses is lacking. Despite popular claims, your body cannot convert its compounds into hormones like progesterone, so creams marketed that way usually don't work as advertised. Talk with a pharmacist or doctor before using it.

Dioscorea villosa · Dioscoreaceae · Root and rhizome (underground stem) · Capsules, tablets, dried root, tinctures, topical creams, tea

An interaction check asks whether these two react with each other — it does not ask whether Wild Yam is a good idea for someone in your situation. Here is what our Wild Yam record says about it on its own.

Wild Yam: dosing

There is no well-established standard dose for wild yam. The amount can vary widely between products and forms (capsules, tinctures, teas, or creams).The safest approach is to follow the directions on the product label and not exceed the recommended amount.

Taking Wild Yam and Danazol Together: Common Questions

Is it safe to take Wild Yam with Danazol?
We do not list a known interaction between Wild Yam and Danazol. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Wild Yam and Danazol have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Wild Yam and Danazol used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Wild Yam in each. That is a conversation for your prescriber, especially if Danazol is being adjusted to a target.
How was the Wild Yam and Danazol combination checked?
Interactions in our licensed database are recorded against drug classes. Danazol is filed under 3 classifications, and Wild Yam has documented interactions with 1 drug class — none of Danazol's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Wild Yam interact with any other medications?
Yes. Wild Yam has 41 documented drug interactions in our database — Danazol is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Danazol interact with any supplements?
Yes. Danazol has documented interactions with 50 supplements in our database — Wild Yam is not one of them. The Danazol interaction page linked on this page lists every one, ranked by severity.
