Surveying the vast biodiversity of the medicinal plant world, this program examines the challenges facing countries rich in such natural resources. The video presents interviews with numerous alternative health experts—including Dr. Jean-Pierre Willem, renowned surgeon, ethnologist, and the last field assistant of Dr. Albert Schweitzer—and documents their knowledge in a wide range of herbal and plant-based treatments. It also studies controversies surrounding the patenting of organisms with medicinal potential, such as Peru’s maca root—a clear demonstration that the interests of powerful pharmaceutical companies don’t always suit those of indigenous peoples.
