Not many natural compounds have been proven to fight cancer. This is largly due to lack of funds and researchers who are interested in natural treatments.
French molecular biologist Mirko Beljanski, PhD was an exception. He reasoned that, “If nature came up with carcinogens, it also came up with anti-cancer substances.” He spent almost 50 years of his research career showing that compounds in the plants Rauwolfia vomitoria, an African herb used in folk medicine, and Pao pereira, a tree native to South America, have significant anti-cancer activity.
