Qi is a concept unique to the theories and principles of Traditional Chinese Medicine (TCM).
According to these theories, Qi is the vital energy that animates the body and protects it from illness and pain. It flows through the body in pathways called meridians.
When it becomes stagnant or depressed, physical and/or emotional symptoms result.
Practitioners of acupuncture and TCM are specifically trained to detect and correct imbalances in the human body.
Treatments are focused on balancing and activating the Qi by manipulating corresponding points on the body.
