EarthNews Radio: Natural Medicines
Aspirin may not look like a flower, but it's one of the many medicines that start out as something found in nature. Studying plants and animals is one of the ways scientist find new medicines for humans.
Jerry Kay spoke to Jack Dumbacher, the Chair of the Department of Birds and Mammals at the California Academy of Sciences:
Dumbacher says that many of the medicines we use come from a natural source: Aspirin, or salicylic acid, is found in willow plants, and ancient people chewed on willow leaves when they got a headache. When we find something that appears to be bioactive in nature, we study it for human use. But many of those substances benefit the animals that are carrying them around as well.
