Gamboge and rosiglitazone, glimepiride

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 rosiglitazone, glimepiride and Gamboge 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.

How we checked

Why No Interaction Is Listed for rosiglitazone, glimepiride

Interactions in our licensed database are recorded against drug classes, not just single drug names. rosiglitazone, glimepiride is filed under 7 classifications — including sulfonylureas, cytochrome p450 2c8 (cyp2c8) substrates, antidiabetes drugs. Gamboge has documented interactions with 5 drug classes — the most serious being corticosteroids (moderate), digoxin (lanoxin) (moderate) and diuretic drugs (moderate) — and none of rosiglitazone, glimepiride’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 Gamboge Itself Has Been Linked To

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

  • Stomach pain / Vomiting Additional detail

    “Orally, abdominal pain and vomiting have been reported with gamboge at doses as low as 200 mg. Deaths have been reported after ingestion of 4 grams of gamboge (18).”

Everything above comes from the Natural Medicines adverse-effect record for Gamboge — expand a row for the licensed statement it rests on. We haven’t matched rosiglitazone, glimepiride 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 rosiglitazone, glimepiride.

The most serious there right now: Activated Charcoal (major), Siberian Cocklebur (major), Acai (moderate), Adrafinil (moderate) and African Wild Potato (moderate).

From our pharmacist’s overview on the rosiglitazone, glimepiride page

“Siberian cocklebur worries me most on this page. Its seeds have caused severe, worsening drops in blood sugar in people, and rosiglitazone with glimepiride (Avandaryl) already pulls glucose down through two separate mechanisms, so these pairings deserve real vigilance.”

About Gamboge

What is Gamboge?

  • Laxative (purgative)
  • Expelling intestinal worms
  • Traditional wound care
  • Use as a yellow dye/pigment

Gamboge is a bright yellow tree resin used historically as a strong laxative and as an artists' pigment, but it is toxic in even modest amounts and is not a safe dietary supplement. Modern interest centers on its compound gambogic acid in laboratory cancer research, which does not make the raw resin safe to take. We recommend avoiding oral use of gamboge.

Garcinia hanburyi · Clusiaceae · Dried resin (gum-resin) from the bark/latex · Resin powder, traditional pills, paint pigment (not a typical modern supplement)

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

Gamboge: dosing

There is no established safe dose of gamboge for any health use, and we do not provide one. Because the resin is considered toxic and is not a recognized supplement, there are no reliable, standardized products with proven dosing.If you ever encounter a product that contains gamboge, do not take it without first talking to a pharmacist or doctor. In general, our recommendation is to avoid oral use entirely and choose safer, well-studied options for problems like constipation.
