Fever Bark
Overview
Fever bark is the bark of an evergreen tree called Alstonia constricta. The tree is native to Australia and grows to 15 meters tall.
Fever bark contains the chemicals yohimbine and reserpine, which can lower blood pressure. These chemicals might also be unsafe.
People use fever bark for high blood pressure, malaria, rheumatoid arthritis (RA), and many other conditions, but there is no good scientific evidence to support these uses.
Don't confuse fever bark with Cinchona, which is sometimes called fever bark or fever tree. These are not the same.
