Question:
Who discovered the cinchona bark as medicine?
Answer:
Tribes in the Amazon used the bark of a shrub called Cinchona to treat fevers and shivering; Spanish priests in this region observed traditional Quechua healers using this bark and started using it themselves to treat the fevers associated with malaria. Many centuries later, the active ingredient from this bark was isolated and called quinine, which is still used in the treatment of malaria today.
