It is 'Wei Qi' that provides subtleness to the flesh and adaptive energy to the skin, promoting the defence mechanisms of perspiration, shivering and goosebumps. When Wei Qi is deficient, environmental forces such as heat, wind, cold and damp can penetrate the flesh and invade the vital organs.
Traditionally herbs that tonify Lung Qi and strengthen the Wei Qi are the perfect ally to help the body maintain its protective Aura.
