doctor, and an ethno-botanist. He has studied the use of botanicals by indigenuous people throughout
he world. In South Africa, he was amazed by the conversations he had with the nomadic San people
living in the deserts. Eighty and ninety year old men and women were able to have very lengthy and
Lucid conversations with him, and when he studied some of their habits, he realized that they were
picking and chewing the leaves of the selenium tortuosm plant. This LED to the beginning of
his studies on what would ultimately become a highly standardized
extract of the botanical, Zebrine.
