Pygeum africanum

The Pygeum africanum tree, belonging to the Rosaceae family, is a tall evergreen of the family Rosaceae found in central and southern Africa, such as Cameroon, Kenya, Madagascar, Congolese Democratic Republic, Equatorial Guinea, Uganda, Tanzania, Angola, South Africa, Ethiopia, Burundi, Rwanda, Malawi, and Nigeria. It grows in tropical and humid equatorial mountain zones, at altitudes between 1000 and 2400 m. Interest in the species began in the 1700s when European travelers learned from South African tribes how to soothe bladder discomfort and treat "old man's disease" with the bark of P. africanum.
