About

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

Despite serious safety concerns, Madagascar periwinkle is used for diabetes, cancer, and sore throat. It is also used as a cough remedy, for easing lung congestion, and to reduce fluid retention by increasing urine production (as a diuretic).

Some people apply Madagascar periwinkle directly to the skin to stop bleeding; relieve insect bites, wasp stings, and eye irritation; and treat infections and swelling (inflammation).

How it works

Madagascar periwinkle might alter the immune system, increase the production of urine (diuretic), and lower blood sugar.

Vinblastine and vincristine, some chemicals that can be taken out of Madagascar periwinkle, are approved by the US Food and Drug Administration (FDA) for use in chemotherapy. These chemicals are used against cancers such as Hodgkin's disease, leukemia, Kaposi's sarcoma, malignant lymphomas, mycosis fungoides , neuroblastoma, and Wilm's tumor.
