Water is the first element of human life, water accounts for about 70% of the composition of the human body, human water metabolism abnormalities will cause a variety of diseases, skin diseases are also the same. Man is the law of the earth! When we study human beings, we must first learn to look at nature, at the earth beneath our feet. How do we look at the world, at the earth? Chinese medicine is called the correspondence between heaven and man. It means that all things in nature and the human body correspond to each other. There are mountains, rivers and lakes in nature, and there are also mountains, rivers and lakes in the human body. Nature has the sea, the Yangtze River and the Yellow River, and the skin of the human body is like the sea, the Yellow River and the Yangtze River in the human body. The human body’s qi goes up and is liquid below. You see when we talk in winter, there will be mist in the mouth, the mouth spitting fog, this is Yang Qi. The human body relies on this Yang Qi to warm our head and to warm our skin as it flows around the body all over the surface. If it is in the upper jiao, yang energy exists as mist, i.e. water vapor, and if it flows downward, it slowly becomes water, which itself is through, and it has a channel from the top to the bottom, and from the surface to the inside. What is this channel? It is the three jiao of the human body, the three jiao is to go water. If water is blocked in the process of collecting from the surface of the body to the inside, skin diseases such as eczema will occur, is a problem with the skin waterway. In life, there are many eczema patients, eat a lot of dampness removal medicine, such as red beans, etc., often eat, but eczema is still very serious, this is why? In fact, it is not too much dampness in the human body, it is the abnormal distribution of water and dampness in the body or the abnormal water channels that cause it. Patients with eczema, you will see a lot of ulcers and running water on the skin, while other places, there may be a lack of water, such as some people have dry lips or hands and feet, etc.. Chinese medicine treatment of eczema is like the treatment of water, south to north, transferring water over, mobilize him, not to solve the problem!
