A surprising large number of modern-day medicines rely on plant-based ingredients. Up to 70,000 plants in the world are believed to have medicinal value, yet the pharmaceutical industry has not yet recognized the extent of their potential. Some 1,000 plants are commercially cultivated, while most are harvested in the wild, in some cases, to the brink of extinction.

Environmental groups are working with the local population to help replenish the valuable trees.
