Quizplus · Accepted Answer

The most likely effective ingredient in the bark from a tree in South America would be quinine, which is found in the bark of the Cinchona tree. Quinine is commonly used to treat malaria and has a long history of traditional use in South America. Atropine is found in the belladonna and hazel trees and is not typically used to treat fevers or chills. Bromelain is found in pineapples and is not known to have properties that would help with a fever or chills.
