May 11-12, 2024 – Misty Meadows Herbal Center, Lee, NH

David will be teaching classes on:

Adaptogens, Lifting the Shadows – Differential Treatment of Depression and Anxiety – and Herbal/Nutritional Protocols for Insomnia and Other Sleep Disorders


The David Winston herbal school has opened to me a world very little known of to many people, I endeavor  to pass the knowledge  and help to many others.
