Butternut and Quinethazone

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

Moderate

DIURETIC DRUGS

Why this applies to Quinethazone

Quinethazone falls under DIURETIC DRUGS — the group Butternut interacts with.

Butternut has stimulant laxative effects. Theoretically, overuse of butternut might compound diuretic-induced potassium loss. There is some concern that people receiving butternut along with potassium-depleting diuretics might be at an increased risk for hypokalemia.
Some diuretics that can deplete potassium include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.
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 thing to keep in mind: Quinethazone is a thiazide-type water pill, and one of its known effects is lowering your body's potassium. Butternut bark works as a stimulant laxative, and when the bowels are pushed harder, potassium can be lost that way too. So in theory, using both together could add up and pull your potassium a little lower than the diuretic alone.

I want to be straight with you, though: this concern is theoretical, based on how each one works rather than real case reports. Low potassium can show up as muscle cramps, weakness, or an irregular heartbeat. If you ever feel those, or if you're considering butternut, please check in with your pharmacist or doctor first.

About Butternut

What is Butternut?

  • Constipation (laxative)
  • Digestive complaints
  • Skin conditions
  • Traditional 'liver' or 'cleansing' remedy
  • Mild laxative in herbal blends

Butternut (Juglans cinerea) is a North American tree whose inner bark was traditionally used as a mild laxative and folk remedy. Modern scientific evidence supporting any of its uses is very limited, and it can cause stomach cramping and other effects, so it should be used cautiously and only with guidance from a healthcare professional.
