"Chausiki, a wild chimpanzee in the Mahale Mountains of Tanzania, was sick. She dozed lethargically while those around her fed. Her urine was dark, her stools were loose, her back was visibly stiff, and she ignored her whimpering young son. She then sought out a little shrub, Vernonia amygdalina, the 'bitter-leaf' or 'goat-killer'. Chausiki stripped away the highly toxic outer layers of its shoots. For twenty minutes she chewed and sucked the more mildly poisonous inner pith. The son tried to copy his mother, but he spat out the bitter plant in obvious disgust. A day later, Chausiki was cured. She travelled swiftly ahead of her group, and fed as usual.
Two scientists were watching her: Mohamedi Seifu Kalunde, a Tanzanian traditional herbalist, and Michael Huffman, an American biologist. The herbalist informed his companion that the bitter-leaf plant is a strong, broad-spectrum medicine used against malaria, schistosomiasis, amoebic dysentery and intestinal worms. Later chemical analysis showed that bitter-leaf pith contains at least ten different compounds active against parasites."
