Doing a little research a plant called iboga or eboka "miracle wood"
(Tabernanthe iboga ) which is endemic to West Africa, Gabon & surrounding areas of the Congo.
"According to legend, the iboga bush arose from a person, just like many other psychoactive plants. According to the mythology of the West African Fang (native people of Gabon):
The last of the creator gods, Zame ye Mebege gave us Eboka. One day . .. he saw . . . the Pygmy Bitamu, high in an Atanga tree, gathering its fruit. He made him fall. He died, and Zame brought his spirit to him. Zame cut off the little fingers and the little toes of the cadaver of the Pygmy and planted them in various parts of the forest. They grew into the Eboka bush."
