The Herbal Highway

The Herbal Highway is a weekly radio show that is dedicated to providing free herbal information to the public. The Herbal Highway enhances the community’s knowledge of herbal medicine and alternative choices to standard medical practices for healing. The Herbal Highway also actively supports and promotes Indigenous land rights, protection of sacred sites and the sustainability of the Earth as integral parts of individual, community and global healing. The Herbal Highway has been airing live on public radio since 1997.

The Herbal Highway began as the vision of Karyn Sanders. In 2006, Sarah Holmes joined her as a regular host after being an occasional guest host in the earlier years. In 2018 Renee Camila and Emiliano Lemus joined the team of hosts. Karyn and Sarah volunteer their time to produce and host the program; Emiliano and Renee are also volunteers.

The Herbal Highway airs on KPFA, the oldest public radio station in the country. KPFA is completely listener sponsored and is located in Berkeley, California. You can live stream through the web and listen to the archives anytime through this link.
