From David Winston I learned an impeccable integrity of practice, demanding standards of looking at the whole person, and intimate knowledge of a 300-plant materia medica. Our class, whether on-site or on-line, has been a community, puzzling together over our triune formulas and case histories. This is an international web of students–from a dozen countries–present in the classroom over our two or three years together.  In class we learned the heart and landscape of David’s lineage in traditional medicine, along with Western, Chinese, Ayurveda and Middle Eastern herbal traditions.  We worked with a unique, large-scale Additional American materia medica.

David stands out as a synthesizer and innovator of healing traditions and disciplines, a master teacher in herbal practice, an historian of the Eclectic and Physiomedicalist movements that shaped American herbal practice.  As a founding member of the American Herbalist Guild, he helped lay the foundation, standards of practice, and educational mission that supports the growth of herbal practice in the United States.

Remember–our class is product of a 40-year teaching career.  At our best, we students carry the integrity of David’s clinical practice, his love of the plants, solid pragmatism, humility, blazing curiosity and the willingness to communicate to the patient whatever inner and outer change is necessary to be whole.
