Dampness is one of the six evils in TCM etiology, which has the characteristics of turbidity, viscosity and descent, and governs qi in summer. Long summer is the turn of summer and autumn. At this time, the sun is still very hot, there is more rain, the hot water is steaming, and the humidity is enough. It is the wettest season of the year.

Characteristics of pathogenic dampness:

1. Dampness is yin evil, which is easy to block qi movement and damage Yang Qi. Wet is similar to water, so it is yin evil.

2, wet turbidity: heavy, that is, heavy and heavy. The clinical manifestations are mostly heavy or persistent. (For example: listless, weak, top-heavy. Damp pathogen is depressed in joints: joint pain is turbid, that is, turbid. (loose stool, turbid urine)

3, wet viscosity: sticky, that is, sticky; Stagnation is stagnation. ((1, viscosity of symptoms. When the large intestine is wet, the stool will be sticky, and when the fu-organs are unfavorable, the stool will be uncomfortable. 2. The duration of the disease. Wet and sticky, adhesion is difficult to solve. Therefore, damp pathogen often has a slow onset, repeated attacks, ups and downs, lingering and difficult to heal, and a long course of disease. ))

4, humidity tends to decline, easy to attack the yin position. Wet water is yin and tends to decline, and the lower part of the human body is yin, so similar water asks for help, so wet evil often hurts the lower part of the human body.
