Learn MoreFrom 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 online, 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 unique experience with herbs from Eastern, Native American, Chinese, Ayurvedic, and Middle Eastern herbal traditions. 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.
