Black Horehound + Goserelin
Goserelin brand name: Zoladex.
We found no known interaction between Black Horehound and Goserelin 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.
Black Horehound and Goserelin
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 Goserelin and Black Horehound 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.
Black Horehound safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Goserelin
Interactions in our licensed database are recorded against drug classes, not just single drug names. Goserelin is filed under a single classification — oral drugs. Black Horehound has documented interactions with 1 drug class — the most serious being dopamine agonists (moderate) — and none of Goserelin’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.

Black Horehound has 23 moderate known drug interactions in our database — Goserelin isn’t one of them. If you take anything else, check it against the full list below.

From our pharmacist’s overview on the Goserelin page
“Goserelin (Zoladex) is given as a small implant under the skin, usually for prostate cancer, certain breast cancers, or endometriosis, and I would want anyone on it to read this list with real attention. All 17 flagged ingredients raise the same basic concern, changing how drugs are absorbed or retained, and the single major-rated one…”

About Black Horehound
What is Black Horehound?
- Nausea and vomiting
- Anxiety and nervous tension
- Sleep problems
- Mild digestive upset
- Coughs and respiratory complaints
Black horehound is a traditional European herb mainly used for nausea, mild anxiety, and digestive upset, but high-quality human studies are lacking, so its effectiveness is largely unproven. It has a strong, unpleasant smell and taste, and its safety has not been well studied, so it should be avoided in pregnancy and breastfeeding and used cautiously by everyone else.
Ballota nigra · Lamiaceae · Above-ground parts (flowering tops and leaves) · Tea (infusion), liquid extract, tincture, capsules
An interaction check asks whether these two react with each other — it does not ask whether Black Horehound is a good idea for someone in your situation. Here is what our Black Horehound record says about it on its own.
Black Horehound: dosing
There is no well-established, standardized dose for black horehound. Traditional use has involved teas made from the dried herb and liquid extracts or tinctures, but reliable dosing from quality human studies is not available.If you choose to use a product, follow the directions on the label and do not exceed the recommended amount.
