What you'll learn in this natural medicine class:

Herbal medicine has been in use for thousands of years, each culture having its own unique system based on the herbs of its bioregion. This course is taught with an ecological and bioregional perspective, focusing primarily on the herbs that grow in our region here in the Northeast. This is a comprehensive four-month certificate training that explores the traditional, practical and environmentally sound ways of using herbs to keep well and treat common illnesses. This course gives a firm and solid foundation in the understanding of herbal medicine.

Topic highlights include

  • The basic anatomy and physiology of each body system and how to promote healing and treat most acute illnesses
  • The history of herbal medicine and how we got to where we are now
  • How to prevent illness, promote vitality and maintain balance in the body through the use of herbs
  • Practical lessons on how to make your own herbal products at home
  • The legal considerations of being an herbalist
  • Guest teachers will share principles of Chinese herbal medicine and herbal synergy
