What is Vitalism?

Vitalism in healing is a clinical strategy based on the principle that Life, Nature, and the Great Spirit from which they arise are fully present in all the tissues of the body, and also in the psyche, the spiritual heart, and the soul, sustaining life and health, providing inspiration and momentum for personal evolution on all levels, and for the fulfillment of the highest purpose in social and spiritual life. Vitalist practitioners employ clinical strategies and methods which support this life power through encouragement of nourishment, digestion, rest, and appropriate activity, identification of purpose in personal life, connection with nature, an active spiritual life, identification and removal of obstacles to cure on all levels, and avoidance of methods which suppress or distort life processes. 

​The North American Institute of Medical Herbalism curriculum is firmly based on vitalist principles throughout every course, and it is the basis of the clinical work in all our teaching clinics and seminars...
