Wei Qi (Defensive Qi) is the TCM equivalent of the immune system. It circulates on the surface of the body, forming a protective shield against pathogenic factors (Cold, Wind, Heat, Damp). Wei Qi is produced by the Lungs from the air you breathe and the food the Spleen transforms. When Wei Qi is strong, you rarely get sick. When weak, you catch every cold going around.
Wei Qi circulates between the skin and muscles, warming the organs and regulating the opening and closing of pores. When it detects a pathogen, it closes pores (causing chills) and fights the invader (causing fever). This is why TCM treats colds at the 'exterior' level — pushing the pathogen out before it penetrates deeper.
Frequent colds (more than 3 per year), slow recovery from illness, spontaneous sweating, catching colds easily from drafts, low energy, pale complexion, shortness of breath, weak voice, allergic rhinitis, and asthma.
