Many patients in our daily clinic ask, “Doctor, I usually pay attention to my diet, my spleen and stomach are not good, I hardly eat cold food, but my tongue is white and there are teeth marks on the edge of my tongue, does this indicate that there is dampness in my body? Where does the dampness come from?” I believe that questions such as these will be encountered by every TCM doctor who has been in clinical practice for many years. Dr. Zhang Dongming believes that dampness can be divided into internal and external dampness, internal dampness, mainly from the diet. For example, over-eating cold, fatty, sweet and greasy things, or irregular diet resulting in hunger and satiety disorders, resulting in the depletion of the spleen and stomach, so that their own transport function is out of order, water and grain does not transform over time to generate dampness. External dampness is often due to dampness, wet clothing wrapped in body, long-term engagement in water work. In addition, there is also external wind and cold fail to pay attention to the cold evil directly into the depths of the internal organs, in the case of insufficient human vitality, dampness invasion of the body caused by many symptoms. So what are the main manifestations of heavy dampness? Mainly: loose stools, sticky toilet and sticky, weakness around the body, less lazy, dark circles under the eyes, heavy breath, scrotal dampness, white and thick tongue moss and tongue edge with teeth marks, abdominal distension is not easy to digest, greasy hair, greasy face, abdominal obesity. 1, dietary therapy to drive away the cold and protect the spleen and stomach. In the cold winter ginger can definitely be said to be a good helper to drive away the cold. Ginger pungent, slightly warm, good at cleaning the meridians and viscera in the Yin turbidity, with the effect of relieving the table to disperse cold, warm abort vomiting, phlegm and cough. Sliced ginger, with the right amount of brown sugar boiled for more than ten minutes, every day adhere to the morning after the decoction to drink, for the health of the spleen and stomach play a very good protective effect. 2, light diet, avoid cold. Excessive consumption of fatty, sweet, thick and greasy things are also prone to dampness, excessive eating cold will increase the burden on the spleen and stomach, and over time make the spleen and stomach cold, resulting in cold and dampness inside. Therefore, people with heavy dampness need a light diet with appropriate cold and warmth. People with spleen and stomach discomfort can drink warm boiled water. 3, Chinese herbal medicine conditioning, both the symptoms and the root cause. People with spleen deficiency and dampness can be fully conditioned by Chinese medicine. The doctor according to the actual evidence of each patient, through the four diagnostic examination, according to the patient’s disease evidence identification and prescription of medicine, the root of the body to drive away cold and damp. Dr. Zhang Dongming is a Chinese medicine practitioner of the Vulcan school in the capital and has been practicing Chinese medicine for more than 40 years. He believes that treating the disease is to treat the middle qi. The so-called middle qi is the qi of the spleen and stomach in the middle jiao, which is the body’s acquired qi and needs to be constantly transformed by diet. The generated Qi acts on the internal organs of the spleen and stomach to transport and transform food, to raise and lower the level of the clear and turbid. Chinese medicine practitioners should start with the middle qi in the diagnosis and treatment of any disease or illness. Through Chinese medicine, it is important to ensure that the patient eats, sleeps and has two bowel movements, which is the natural law of physiological health of any person. He emphasizes that the human being is born with the middle qi first and the four dimensions later. Zhongqi is like an axis, and the four dimensions are like a wheel, the axis moves the wheel and the wheel moves the spirit. Regardless of the disease, if the middle qi still exists, the person will not be sick. When the middle qi is gradually restored, the disease can be cured. In addition, in the “Ancient Chinese Medicine of the Circle Movement” by Peng Ziyi, a middle school medical doctor in the late Qing Dynasty, there is also an explanation of the middle qi of the human body: “People have life because they have the middle qi of creation. Since the middle qi is dead, so is death. Our body is light and healthy, we sleep and eat well, and our spirit is lively, which is the symbol of sufficient middle energy. Before a patient is about to die, he will want to have a bowel movement and be nauseous and vomit, which is a symbol of the separation of the upper and lower parts of the body and the death of the middle energy. A person who is not sick but has a short spirit and sleep and food are not sweet” is a symbol of insufficient qi. The above explanation is sufficient to illustrate the importance of the middle qi in the human body.
