Manuel Incra Mamani
Bolivian Incan bark and seed hunter / From Wikipedia, the free encyclopedia
Manuel Incra Mamani (? – 1871) was a Bolivian cascarillero (bark and seed hunter) from Coroico.[1] He may have been of either Quechua and/or Aymara descent. Mamani found a cinchona tree species (Cinchona ledgeriana syn. C. calisaya) that had a higher proportion of quinine than most others.[2][3] This species went into Dutch commercial cultivation, providing most of the world's quinine well into the 20th century.[4][5][6]
