Gaultheria is a genus of ericaceous shrubs with evergreen foliage, and, often, edible berries native to Asia, Australasia, North America, and South America. The angiosperm species (about 135) belong to the family Ericaceae, order Ericales. Examples are the American winter-green (G. procumbens) and the larger-fruited salal of Northwestern America (G. shallon). Many of them are grown for use as ornaments in garden. Some of them produce edible fruit, e.g. salal. G. leucocarpa is used as herbal medicine for rheumatoid arthritis.
