Authors Luke Manget and Annette Saunooke Clapsaddle will discuss Manget’s new book “Ginseng Diggers: A History of Root and Herb Gathering in Appalachia” at 3 p.m. Saturday, April 30, at City Lights Bookstore.

The harvesting of wild American ginseng, the gnarled, aromatic herb known for its therapeutic and healing properties, is deeply rooted in North America, but nowhere has it played a more important role than in the southern and central Appalachian Mountains.

Manget is an assistant professor of history at Dalton State College in Dalton, Georgia. Clapsaddle, an enrolled member of the Eastern Band of Cherokee Indians, holds degrees from Yale University and the College of William and Mary. Her novel “Going to Water” won the Morning Star Award for Creative Writing from the Native American Literature Symposium and was a finalist for the PEN/Bellwether Prize for Socially Engaged Fiction.
