Increasingly, medicinal species that reside in natural areas have received scientific and commercial attention. In the United States, of the top 150 prescription drugs, at least 118 are based on natural sources. A child suffering from leukemia in 1960 faced a 10 percent chance of remission; by 1997, the likelihood of remission had been increased to 95 percent thanks to two drugs derived from a wild plant native to Madagascar.
