Some patients ask how damp heat arises. In order to explain the reason more graphically, I played an analogy: damp heat is generated, partly due to external dampness, invasion of the body; another part and the spleen and stomach function and diet have a lot to do with. For example, a river, if the speed of the water is faster, and the water is relatively clean, there will rarely be silt at the bottom of the river; on the contrary, it is easy to produce silt, and over time fermentation will produce heat. And external dampness is like a sudden mud, impurities mixed into the river, if the amount is not large and the speed of water flow is relatively fast, can be completely through the river’s self-cleaning function will be discharged; on the contrary, will also produce silt, and even congestion river. The digestive tract is the same reason, if the digestive attraction itself is not good (weak spleen and stomach, transport and transformation failure), coupled with the frequent diet of cold, greasy, spicy, irritating food, etc., it is easy to water damp stop accumulating, and over time into damp heat.
