This is a holistic system of medicine that originated in China more than 3000 years ago. Elements of this form of healing include meditation, herbal therapy, nutrition therapy, massage, acupuncture, etc. TCM stresses the balance of the vital force, Qi, which flows through the human body. Qi, according to TCM, depends upon harmony between Yin and Yang. Disturbance in the balance between Yin and Yang can lead to problems in the spiritual, emotional, physical, and mental balance of an individual.
