NAT 303

Holistic Pathology & Protocols Online


This course guides students in the fundamental principles of naturopathy or natural therapeutics. Emphasis is placed on the science and philosophy of healing using a variety of techniques that are in harmony with nature and the individual client. The varied techniques that a Holistic Health Consultant employs are covered, focusing on the desired outcome to increase the natural vitality of the client and bring the system back into balance. We examine the belief fundamental to natural healing that the human body contains a strong power to heal itself. While examining this belief we also look at how the Holistic Health Consultant is able to stimulate this power by instructing each client in how to maintain health once it is achieved, increasing vitality and building up one’s resistance through improved nutrition and a harmonious lifestyle.
