Pathogenic Factors
Dampness
Dampness is a Yin factor and damages the Yang functions of the body. Dampness has a very close connection to the Spleen, which is in charge of transformation and transportation. Dampness leads to the obstruction and stagnation of the Qi- Blood and Body Fluid circulation. Dampness is heavy and clammy, viscous, and lingering. Therefore, Dampness problems result in feelings of heaviness in the concerned body area.

Dampness is divided into internal and external Dampness:
External Dampness External Dampness is caused by damp or wet climate, wearing wet or moist clothing or by working in a damp or wet environment. It can manifest in the body-surface and attack joints, muscles or Channels.
Internal Dampness Internal Dampness always involves the Spleen, weakening the Spleens' function of transformation and transportation. The Spleen sends the Food Qi to the Lungs; therefore the Lungs are affected by Dampness as well. Traditionally it is said that Dampness is produced by the Spleen and stored in the Lungs. Since the Kidneys are connected to the congenital energy, the fundamental disposition for Dampness problems is found here. Dampness in combination with Cold leads to stagnation and pain. Dampness in combination with Heat is the cause of severe internal diseases. Internal Dampness can be caused as a reaction to Yin Deficiency. Sometimes patients develop a preference for dampness producing foods in order to compensate the Yin Deficiency. The Yin Deficiency is as a result masked by the development of Dampness.
