Indian Cassia and Bendroflumethiazide

Here is the interaction we found between these two, with the evidence behind it.

Moderate

DIURETIC DRUGS

Why this applies to Bendroflumethiazide

Bendroflumethiazide falls under DIURETIC DRUGS — the group Indian Cassia interacts with.

Theoretically, Indian cassia might increase the risk of potassium depletion in patients taking diuretic drugs. However, this has not been shown in humans. Indian cassia leaf extract 200-400 mg/kg body weight has shown mild diuretic activity in animal research. The effect of Indian cassia on urine volume and electrolyte loss was similar to that of furosemide. Until more is known, use with caution.
Severity Moderate Likelihood Possible Evidence D

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

Here's the gist for bendroflumethiazide, a thiazide-type water pill that lowers blood pressure and helps your body shed extra fluid. One of its known downsides is that it can pull potassium out along with the water. The concern here is that Indian cassia showed mild diuretic activity in animal studies, so in theory stacking it on top of your thiazide could nudge your potassium a little lower.

I want to be honest about the evidence though: this is based only on lab and animal research, not people, so the real-world risk is likely small. Sprinkling cassia (Indian bay leaf) in your cooking almost certainly won't matter. Concentrated extracts or oils are a different story. If you ever feel unusually weak, crampy, or lightheaded, check in with your pharmacist or doctor before changing anything.

From our pharmacist’s overview on the Bendroflumethiazide page

“Bendroflumethiazide, a thiazide water pill prescribed for high blood pressure, sits at the serious end of the interaction spectrum, and the ten major-rated entries deserve attention first. Most of the 227 supplements on file either stack their own blood-pressure-lowering effect on top of the drug's or deepen the potassium loss it alrea…”

About Indian Cassia

What is Indian Cassia?

  • Flavoring food
  • Digestive upset
  • Blood sugar support
  • Cold and cough relief
  • Antimicrobial

Indian Cassia (Cinnamomum tamala), also known as Indian bay leaf or tejpat, is an aromatic leaf used widely as a cooking spice and in traditional medicine across South Asia. Human evidence for its health benefits is very limited, so it is best enjoyed as a culinary spice rather than relied on to treat any condition. Used as food it is generally well tolerated, but talk to your pharmacist or doctor before using concentrated supplements or oils.
