David is interviewed as an Herbal Elder by Everything Herbal

The two year course in Clinical Herbalism is truly a treasure trove of information. For anyone interested in herbalism take this course you will not be sorry. David Winston is encyclopedic with his knowledge. David is very demanding, for good reasons. He only wants the best. Wait until he teaches the Native American portion of the course, you will see another side of him. The course is very well rounded: botany, chemistry, traditional uses, and the extensive materia medica. You will be sitting in class with doctors, chemists, farmers, therapists, grandmothers, plant lovers, you name it! This course was simply awesome!!!
