The bottom line No known interaction

We found no known interaction between Calumba 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.

Interaction report

Calumba 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 Calumba 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.

Calumba safety at a glance

Calumba overall Use caution Little modern safety data exists, so use it cautiously and ideally under professional guidance.

Pregnancy Avoid Safety is unknown, so it is best avoided during pregnancy.

Breastfeeding Avoid There is not enough information to consider it safe 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 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. Calumba has documented interactions with 3 drug classes — the most serious being antacids (minor), h2-blockers (minor) and proton pump inhibitors (ppis) (minor) — 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.

Keep it in perspective

What to actually watch for

What Calumba Itself Has Been Linked To

This is not an interaction — nothing below involves Goserelin. It is the side-effect record for Calumba on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Calumba, this list is the first place to look.

Vomiting Additional detail
“Orally, large doses of calumba may cause vomiting and epigastric pain (18).”

Everything above comes from the Natural Medicines adverse-effect record for Calumba — expand a row for the licensed statement it rests on. We haven’t matched Goserelin to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Goserelin.

Everything else you take

See Every Supplement That Interacts With Goserelin

This page covers Calumba only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Goserelin page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

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 Calumba

What is Calumba?

Poor appetite
Digestive upset and indigestion
Nausea
Diarrhea
As a bitter tonic

Calumba is the dried root of an African climbing plant that has long been used as a bitter tonic to stimulate appetite and ease digestive complaints. Modern scientific evidence for these uses is very limited, and its safety has not been well studied, so it should be used cautiously and avoided during pregnancy and breastfeeding.

Jateorhiza palmata · Menispermaceae · Dried root · Dried root, powder, tincture, liquid extract, capsules

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

Calumba: dosing

There is no well-established standardized dose for Calumba. Traditional sources used the dried root, powder, tinctures, or liquid extracts, but reliable modern dosing guidelines do not exist.If you choose to use a Calumba product, follow the directions on the label and do not exceed them.

From our Calumba monograph — the full record covers uses, side effects and every documented interaction.

Goserelin implant is in a class of medications called gonadotropin-releasing hormone (GnRH) agonists. It works by decreasing the amount of certain hormones in the body.
