- Origin of Medicines: From Plants or the Laboratory?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I am a high school student with a most interesting biology teacher,
- but I now have a problem. My teacher tells the class that all medicines now
- come from experiments in the laboratory. My father insists that all medicines
- come from plants. Who is right? I would like to know, so I can both respect
- my Father and make a good grade at school.
-

- ANSWER: You have the right attitude, and now can learn an important lesson.
- Absolute statements (that use the words "all" or "none") are seldom completely
- correct. Both Dad and your teacher are right, but only to some extent, and
- neither person is totally correct. History shows that plants were the primary
- source of medicinal chemicals for centuries. Aspirin, digitalis (used for
- certain heart problems) and quinine (used to treat malaria) are but a few that
- you may be familiar with. Most recently, a new experimental drug (taxol) that
- could be used to treat cancer of the ovary was discovered in the bark of the
- Pacific yew tree.
- Although about 25 percent of the medical drugs now sold are derived from
- plants, laboratory research has taken priority during the last 20 years. New
- drugs can be created from scratch using biochemical techniques. Once the new
- formula has been found to be effective in treating diseases it can then be
- manufactured in large quantities.
- However, certain scientists still believe that many beneficial compounds
- remain to be discovered in plants. Of the estimated 265,000 plant species in
- the world, only 5 percent have been studied. There could be as many as 40,000
- plants with naturally occurring chemicals that would be useful, according to
- some experts in botany.
- Today the science of Ethnobotany is the center of the focus of searching
- for new medicines in plants. Ethnobotany, combining anthropology (the study
- of mankind) and botany (the study of plants) considers how native healers use
- plants as medicine. This may develop into a race against time, as fewer young
- people follow in the footsteps of their tribal medicine men, and as the
- forests of this earth are destroyed. The National Cancer Institute now
- sponsors the Plant Collections Program, in cooperation with botanical
- institutes, that sends scientists into the tropics of Asia and Africa,
- searching for and collecting plants that may be the source of new medicines in
- the future.
