A type of Qi (energy, life-force) in our body also known as “Wei Qi” meaning to “defend” or “protect.” Defensive Qi circulates in the skin and muscles to protect and warm the body against external pathogenic factors. This is another form of True Qi that is more yang relative to Nutritive Qi (the other form of True Qi) since it flows in the outer layers of the body. Defensive Qi is in the Exterior and protects.
