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.
