Combretum Micranthum and Quinidine

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 Quinidine and Combretum Micranthum 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.

Combretum Micranthum safety at a glance

Combretum Micranth... overall Use caution Used widely as a traditional tea, but human safety data are very limited.
Pregnancy Avoid Not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid No reliable safety data while breastfeeding, so avoid use.

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

How we checked

Why No Interaction Is Listed for Quinidine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Quinidine is filed under 9 classifications — including cytochrome p450 2d6 (cyp2d6) inhibitors, qt interval-prolonging drugs, p-glycoprotein substrates. Combretum Micranthum has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and diuretic drugs (moderate) — and none of Quinidine’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.

Everything above comes from the Natural Medicines adverse-effect record for Combretum Micranthum — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Quinidine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Quinidine column appears here.

From our pharmacist’s overview on the Quinidine page

“Grapefruit belongs nowhere near quinidine. The juice blocks the main enzyme that clears this heart rhythm medicine, so quinidine levels can climb into dangerous territory, and it leads a list of 207 supplement and herbal ingredients I would treat with real seriousness, 15 of them rated major.”

About Combretum Micranthum

What is Combretum Micranthum?

Combretum Micranthum
  • Digestive upset
  • Liver and gallbladder support
  • Fever
  • Weight management
  • Mild urinary or fluid retention
  • Traditional opium withdrawal aid

Combretum micranthum (kinkeliba) is a West African shrub whose leaves are brewed into a traditional tea for digestion, liver complaints, and fever. Solid human studies are lacking, so its benefits remain unproven, and people who are pregnant, breastfeeding, or have liver or kidney problems should be cautious and talk to a healthcare professional first.

Combretum micranthum · Combretaceae · Leaves (mainly), and sometimes stems and roots · Tea (herbal infusion or decoction), dried leaf powder, capsules, liquid extracts

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

Combretum Micranthum: dosing

There is no established standardized dose for Combretum micranthum. Traditionally, a handful of dried leaves is steeped in hot water to make a tea, but the strength varies widely from one preparation to another.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount.

About Quinidine

What Is Quinidine Used For?

Brand names: Quinaglute Duratabs, Quinaglute, Duraquin, Cardioquin, Cin-Quin, Quinora, Lin-Qin, Quinova, Quinidex Extentabs

Quinidine is used to help restore a normal heart rhythm in people with atrial fibrillation or atrial flutter (irregular, rapid heart rhythms originating in the upper chambers). It is also used on an ongoing basis to reduce how often those episodes come back, in patients whose episodes are frequent and poorly tolerated — but only after other options have been tried first.

Quinidine sulfate oral tablets and quinidine gluconate extended-release oral tablets are both approved for these heart-rhythm uses. Quinidine sulfate tablets are additionally used as part of an approved treatment regimen for life-threatening Plasmodium falciparum malaria, in combination with quinidine gluconate injection (the central component of that regimen). Both formulations may also be used to suppress recurrent, documented life-threatening ventricular arrhythmias (dangerous rapid rhythms in the lower chambers of the heart), such as sustained ventricular tachycardia.
