The roots of Kellogg's Yampah were eaten and tea could also be made from the roots to ease bladder problems. The roots could also be made into hair brushes (Strike, p. 103-104). 

Information on growing Kellogg's Yampah can be found here on Calscape. 

Kellogg's Yampah is often used in butterfly gardens as it supports the Anise Swallowtail, among other butterflies and moths.
