Hydroxychloroquine is a synthetic derivative of a compound called quinine. Quinine is a naturally occurring compound in plants. The origins of quinine have been traced to the tree bark of a genus of plants called Cinchona. Cinchona trees and shrubs are native to South America. Hybrid species have been cultivated in other parts of the world.
