Throughout history, trees have played a crucial role in medicine, even though their bark and wood are rarely considered food. Some of the most important treatments ever discovered came from tree extracts, such as quinine from the Cinchona tree, which was used for centuries to treat malaria after being discovered by the Quechua people and later introduced to Europe as a “wonder cure.” Similarly, the origins of modern aspirin trace back to the White Willow, whose bark contains salicylic acid used to relieve pain long before synthetic versions existed. These examples highlight how traditional knowledge and natural resources laid the foundation for modern medicine, and how nature continues to influence treatments even today.
