Sumac Originally from central China, sumac is able to withstand an extensive range of weather conditions. It has attractive leaves that produce brilliant autumn colors. Among traditional medical practitioners and Western scientists, it is considered a medical jewel. Its fruit and extracts contain proteins, coagulants, and powerful astringents. It has been used to treat coughs, asthma, fever, lost appetite, ulcers, and stomach and respiratory disorders. The gall from this small tree has antibacterial effects, and some extracts may even be effective against HIV-1. (Rhus chinensis) Photograph by Yu-Min Shui
