Medicinal Treasures of the Rainforest

The widespread destruction of tropical rainforest ecosystems and the consequent extinction of numerous plant and animal species is happening before we know even the most basic facts about what we are losing.

Covering only 6 percent of the Earth's surface, tropical moist forests contain at least half of all species. The abundant botanical resources of tropical forests have already provided tangible medical advances; yet only 1 percent of the known plant and animal species have been thoroughly examined for their medicinal potentials. Meanwhile, 2 percent of the world's rainforests are irreparably damaged each year.

Approximately 7,000 medical compounds prescribed by Western doctors are derived from plants. These drugs had an estimated retail value of US$43 billion in 1985. Seventy percent of the 3000 plants identified by the United States National Cancer Institute as having potential anti-cancer properties are endemic to the rainforest. Tropical forest species serve Western surgery and internal medicine in three ways. First, extracts from organisms can be used directly as drugs. For maladies ranging from nagging headaches to lethal contagions such as malaria, rainforest medicines have provided modern society with a variety of cures and pain relievers.

[…]

Secondly, chemical structures of forest organisms sometimes serve as templates from which scientists and researchers can chemically synthesize drug compounds.[…]

Finally, rainforest plants provide aids for research. Certain plant compounds enable scientists to understand how cancer cells grow, while others serve as testing agents for potentially harmful food and drug products. Tropical forests offer hope for safer contraceptives for both women and men. The exponential growth of world population clearly demonstrates the need for more reliable and effective birth control methods. Worldwide, approximately 4,000 plant species have been shown to offer contraceptive possibilities. The rainforest also holds secrets for safer pesticides for farmers. Two species of potatoes have leaves that produce a sticky substance that traps and kills predatory insects. This natural self-defense mechanism could potentially reduce the need for using pesticides on potatoes. Who knows what other tricks the rainforest might have up its leaves?
