Health topics

Where Mauby Bark appears in symptom search, and why. Being listed doesn't mean it's a proven treatment.

  • High Blood Pressure

    In a very small 2-week study, blood pressure fell in some people drinking mauby. Bigger studies are needed. It may interact with warfarin.

Traditions that use it

  • Caribbean Folk Medicine

    Mauby, a bitter drink made from the bark, is widely used in the Caribbean as a folk remedy.

Safety

Interactions with medicines

  • Mauby may interact with warfarin (a blood thinner). In a case report, a 70-year-old man on warfarin had dangerously thin blood (a very high INR) after he began drinking mauby. If you take warfarin, talk to your doctor before drinking mauby.[1]

    Technical detail: INR > 8.0 and later 4.8 on a previously stable dose; Naranjo score 6 (probable interaction).

What does the research say?

Traditional use

These are traditional uses, not proven treatments.

  • Mauby is a bitter dark drink made from the bark of the mauby tree. It's commonly used in the Caribbean as a folk remedy with many claimed health benefits.[1]

Laboratory & animal research

Lab and animal results show what might be worth studying in people. They don't show that the herb has these effects in humans.

  • Lab analysis of the bark of a related tree, Colubrina elliptica, found natural soap-like compounds called saponins.[2]

    Technical detail: mabiosides C–E, novel triterpenoid saponins, isolated with mabioside B from Colubrina elliptica bark.

Research in people

  • In a small study, 28 people with high blood pressure drank bottled water, coconut water, mauby, or a mix of coconut water and mauby for 2 weeks. Blood pressure fell in some people in the mauby and coconut water groups. Mauby mixed with coconut water gave the biggest drops. The study was very small and short.[3]

    Technical detail: 7 per group; significant systolic decreases in 71% (coconut water), 40% (mauby) and 43% (mixture); diastolic decreases in 29%, 40% and 57%; largest drops with the mixture were 24 mmHg systolic and 15 mmHg diastolic.

In short

May interact with the blood thinner warfarin; talk to your doctor before drinking it if you take warfarin.
