Can a medicine cause a war? When chemists isolated a new compound from the bark of a South American tree, they had no idea they were changing world history, and cocktails, forever. 

If we look at how the bark of the cinchona tree is used to treat malaria, we can see cutting edge chemistry showing quinine binding to an enzyme that is essential for the malaria parasite’s survival. But if we look from another angle, we can see how that coincidental affinity may have been a major contributing factor to World War One.
