Aromatic plant used most often to enhance the flavor of foods. Like all plant extracts, sage contains components that function as antioxidants. However, most of these components are fragrant and capable of causing irritation when used on skin. Taken internally, sage has anti-inflammatory properties though there's only limtied research demonstrating that this applies when sage is used on skin. The anti-inflammatory compound in sage is believed to be ursolic acid (Source: Planta Medica, September 2007, pages 1.190-1,191; and Journal of Ethnopharmacology, May 2001, pages 125-132). One of the natural components responsible for sage's fragrance is camphor, a known skin irritant (Source: www.naturaldatabase.com).
