Practical Information

Forage Value
Livestock rarely eat annual eriogonum. It offers no forage value for cattle and only fair value for sheep and deer.
Uses
Native Americans boiled the plant and used the resulting liquid as a lotion to treat ant bites and mouth sores. They sometimes rubbed the fresh leaves on bison and deer hides to help tan them.
