Overview

Madagascar periwinkle is a plant. The parts that grow above the ground and the root are used to make medicine.

Madagascar periwinkle is used for diabetes, cancer, sore throat, cough, insect bite, and many other conditions, but there is no good scientific evidence to support these uses. Using Madagascar periwinkle can also be unsafe.

Purified forms of some chemicals found in Madagascar periwinkle are approved by the U.S. Food and Drug Administration (FDA) to be given by injection for the treatment of cancer. These drugs have serious side effects and should be administered only under medical supervision. Madagascar periwinkle is considered unsafe for self-medication.
