How long of classes does it take to become a herbalist?

I am a Master Herbalist. I got my diploma from the American College of Healthcare Sciences, at www.achs.edu. My program took me about 2 years to complete, but since it is distance learning and self-paced, you may be able to do it faster or slower, depending on your schedule and needs. In order to get my diploma, I completed 2 herbal Materia Medica course, a course on Holistic Structure and Function of the Body, a course on Holistic Pathology and Protocols, and a course on Holistic Health Consulting and Business Skills.
