Uses
Cinchona officinalis is a medicinal plant, one of several Cinchona species used for the production of quinine, which is an anti-fever agent. It was historically important in the prevention and treatment of malaria, before being superseded by synthetic and semi-synthetic antimalarial drugs, many of which are derivatives of Cinchona alkaloids. Other alkaloids that are extracted from this tree include cinchonine, cinchonidine and quinidine.[4]
