Good Tern Natural Foods Cooperative, 750 Main St., hosts an “Essential Fall Elixers” class with clinical herbalist and health educator Melanie Rose Scofield Wednesday, Oct. 12, from 7 to 8:30 p.m.

The talk will include a tour of the store. The event is free, but preregistration is requested at 594-8822.

Fire cider is a time-tested kitchen remedy for colds, flus and associated congestion. Scofield will demonstrate how to make this fiery concoction.

Also on the agenda is a mulled cider, with added astragalus and other immune-boosting herbs.

Scofield will also explain about chaga — a nutrient-rich fungus found locally on birch trees. An earthy addition to any tea, chaga is most commonly combined as a chai with tea leaves, cardamom, cinnamon, and other spices.

Scofield is the founder and director of the Earthwalk School of Herbal Traditions in Rockport, which offers medicinal plant walks, children’s summer programs, workshops and herbal apprenticeships for all levels. She trained with the Global College of Natural Medicine, then completed an advanced clinical herbalist training at Boston School of Herbal Studies in 2007, where she is currently a faculty member.
