Between 1960 and 1997 the chances of remission for a child suffering from leukemia rose from 10 to 95 percent due to two derived from the Madagascar periwinkle. Medicines from this plant have also been used to treat diabetes and high blood pressure.
Another revolutionary cancer fighting drug, Taxol, was discovered in the bark of the Pacific Yew, a native of old growth forests in the Pacific Northwest.
Medicinal plants that reside in natural areas have received increasing scientific and commercial attention. In the United States, of the top 150 prescription drugs, at least 118 are based on natural sources.
In recent years, studies have found public health benefits from native plant communities as well as native plant species. Studies have found stronger immune systems and reduced incidence of asthma for children in areas dominated by native plants compared to areas dominated by non-native plants or pavement. The 2018 Forest Service study is the first to indicate that native plant diversity can protect public health.
Ecosystem services also support health and life (e.g., by providing air, water, food, raw materials, medicines), security (e.g., by mitigating extreme weather events, spread of vector-borne diseases), and quality of life (e.g., by supporting mental and physical health, cultural identity, recreation), among many other things (Ecosystem Services Toolkit, Canada 2015).
