Yerba Santa is a Borage relative that grows in a variety of habitats including chaparral and Coast Redwood forests.
The leaves have historically been used to treat asthma, upper respiratory infections and allergic rhinitis. The Concow tribe calls the plant wä-sä-got’-ō. The Chumash used it as a poultice for wounds, insect bites, broken bones, and sores. It was also used in a steam bath to treat hemorrhoids.
