ANTIHYPERTENSIVE DRUGS

1 of 2

Why this applies to Hydrochlorothiazide, Propranolol

Hydrochlorothiazide, Propranolol falls under ANTIHYPERTENSIVE DRUGS — the group Combretum Micranthum interacts with.

Theoretically, taking Combretum micranthum leaf with antihypertensive drugs might increase the risk of hypotension.
Clinical research suggests that Combretum micranthum leaf reduces blood pressure.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Your Inderide combines two blood pressure medicines: hydrochlorothiazide (a water pill) and propranolol (a beta blocker). Both already work to lower your blood pressure. Kinkeliba tea (Combretum micranthum) has been shown in some early research to lower blood pressure on its own, so pairing it with this medication could push your numbers down a bit more than expected.

If that happens, you might feel dizzy, lightheaded, tired, or shaky, especially when standing up quickly. The evidence here is fairly limited, so this is more of a be aware than a be alarmed. An occasional cup of tea may not do much, but regular or concentrated use is worth mentioning to your pharmacist or doctor, who can keep an eye on your blood pressure.

DIURETIC DRUGS

2 of 2

Hydrochlorothiazide, Propranolol also falls under DIURETIC DRUGS.

Theoretically, taking Combretum micranthum leaf with diuretic drugs might increase the risk of hyponatremia.
Combretum micranthum leaf has shown natriuretic effects in preliminary clinical research.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Inderide combines two medicines: hydrochlorothiazide, a water pill that already makes you lose salt and water, and propranolol, a beta blocker. The piece that matters here is the diuretic. Early human research hints that kinkeliba tea has its own mild water-flushing (natriuretic) effect, meaning it can nudge your body to dump more sodium too.

Stack that on top of hydrochlorothiazide and the worry is low sodium (hyponatremia). Watch for headache, nausea, dizziness, muscle cramps, confusion, or feeling unusually weak or tired. This is still theoretical and based on limited evidence, so it is not a reason to panic. An occasional cup likely matters less than concentrated supplement doses. Before adding kinkeliba, check with your pharmacist or doctor, who may keep an eye on your sodium.

From our pharmacist’s overview on the Hydrochlorothiazide, Propranolol page

“Inderide combines hydrochlorothiazide, a water pill, with propranolol, a beta blocker, so a supplement that also lowers blood pressure or pulls potassium out of the body hits the drug on its own turf. That describes most of this list, and I'd approach it with genuine care.”

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.
