Recent clinical studies have verified that red alder (Alnus rubra) contains betulin and lupeol, compounds shown to be effective against a variety of tumors. Native Americans used Red Alder bark to treat poison oak, insect bites, and skin irritations. Blackfeet indians used an infusion made from the bark of Red Alder to treat lymphatic disorders and tuberculosis.
There has been extensive research done on this chemical at the University of Minnesota, Duluth among other educational institutions.
