About Our Program

Thank you for visiting David Winston’s Center For Herbal Studies’ (DW-CHS) website. David Winston, RH (AHG), an internationally respected herbalist, is the dean and primary instructor for this program. He teaches throughout the US, Canada, and the UK and has been teaching the two year DW-CHS program for almost 40 years.

Our philosophy: Good herbalists treat people, not diseases, and in our program we strive to teach the skills necessary so that each student can accomplish that goal. We focus on differential diagnosis skills, materia medica and therapeutics which are essential to individualize treatment and help patients to not only resolve symptoms, but create constitutional change needed for physical, emotional and spiritual wellness.

The program runs from September through August for two consecutive years. The class is held in Washington, NJ* and online via live webcast.

*Due to the Covid 19 pandemic, if we can have the on-site class safely we will.  If not, all students will go on-line until things improve (once a vaccine is widely available).  When we can return to the classroom safely, we will.  No one really knows at this point and we will keep students updated.

For more information about the course please refer to the Herbalist’s Training Program tab. If you have any further questions please feel free to contact us.

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 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.
