The owner of The Good Herb is very knowledgeable. I have attended several of her classes. She was thorough and very interesting. At the most recent one I attended we made a elderberry syrup that was awesome, as well as other cold and flu remedies. I learned a lot and was glad I went. She has literally hundreds of herbs for sale at her shop. It's a pretty place. Ask for a tour of her gardens if it's summer time. There's some rare plants I'd never seen before.
