Pathogenic Factors
Wind
Wind is a Yang factor and damages the Yin in the body. Often Wind behaves like a catalyst, which enables other Pathogenic Factors to invade the body (for example Wind-Cold, Wind-Damp). Wind and its clinical manifestations are similar to those of the meteorological phenomenon from which it derives its name: it comes and goes quickly, moves swiftly, and blows intermittently. Wind pains appear and disappear suddenly. Pains with changing localization are frequently due to Wind. Wind attacks the upper part of the body, the Lungs, the Liver and the skin. External Wind obstructs the flow of Defense-Wei-Qi.

Wind is divided into internal Wind and external Wind:
External Wind External Wind is caused by windy climate and weather change. It can manifest in the body-surface and attack joints, muscles or Channels. External Wind usually appears in combination with other Pathogenic Factors (for example, Wind-Cold, Wind-Heat, or Wind Dampness).
Internal Wind Internal Wind is always connected with a disturbance of the Liver.
