Traditional Chinese medicine believes that normal physiological activities can only be carried out if yin and yang maintain a relative balance. If they are destroyed by some pathogenic factors, then no matter which side of yin and yang in the body rises and falls, diseases may occur. Therefore, there is a saying that "one yin and one yang is the Tao, and excess is the disease". For example, according to the principle of "the growth and decline of yin and yang", diseases with excessive yin deficiency often lead to yang failure, with symptoms such as chills, cold hands and feet, pale face, pale tongue and weak pulse. Yin deficiency often leads to hyperactivity of yang, with symptoms of hyperactivity of yang such as irritability, insomnia, dry mouth, red tongue and rapid pulse. According to the principle of "Yin and Yang are mutually rooted", when either side of Yin and Yang has obvious deficiency, it will often lead to the deficiency of the other side, that is, "Yang impairs Yin" and "Yin impairs Yang". In the late stage of some chronic diseases, syndromes of deficiency of both yin and yang often appear.

The diagnosis of diseases can also be based on the view of yin and yang. In the process of syndrome differentiation, we must first distinguish between "Yin and Yang", which is the basis of syndrome differentiation in TCM. This is the truth in Huangdi Neijing that "those who are good at diagnosing diseases should look at the color and pulse, and don't talk about yin and yang first".

For example, the facial color is brighter than normal people, and the facial color is more embarrassing than normal people. The loud voice belongs to Yang, and the small voice belongs to Yin. Fast, shallow and strong belong to Yang, slow, deep and weak belong to Yin, and so on. By distinguishing the yin and yang attributes of these symptoms, we can clearly understand the location, nature, degree and changing trend of the disease, so as to further distinguish the yin and yang attributes of the whole disease.

After understanding the nature of yin and yang of the disease, the focus of treatment should be to adjust yin and yang, so as to finally restore the balance and coordination of yin and yang. If it is cold syndrome (yin), balance it with medicine (yang) that can give off heat; If it is fever (yang), use cold medicine (yin) to resolve it; If there is an excess of yin and yang in one aspect, use drugs with expelling effect to "diarrhea" the excess; If one aspect of yin and yang is insufficient, it is necessary to supplement the medicine ... These are the treatment principles of traditional Chinese medicine, namely "heat is cold", "cold is heat", "excess is diarrhea" and "deficiency is tonic". These principles are also determined according to the relationship between yin and yang.

Many people in modern society have symptoms of yang deficiency, and one of the most important reasons is overwork, including physical and mental consumption. These people's life pressure is relatively high. In order to achieve various life goals, they are unconsciously overdrawing their bodies. When there is a deficit, their bodies will start to be afraid of cold, cold and fatigue ... For people with yang deficiency, I suggest eating some hot food, such as mutton and black-bone chicken, and eating less cold food, especially watermelon, ice cream and other anti-season foods. The most commonly used ingredient for tonifying yang is cinnamon. Cinnamon is sweet and warm, and can be used at home for 5? Cinnamon10g and japonica rice100g are very effective in improving the symptoms of yang deficiency. Old people can soak cinnamon and medlar in white wine for half a month, about 20 ml each time, before drinking, which can also improve the symptoms of yang deficiency. In addition, you should exercise regularly to keep your mood comfortable. Here, I would like to remind those patients with yin deficiency and hyperactivity of yang, heavy yang fire, phlegm in phlegm, heavy lung heat and exogenous fever not to take cinnamon, and patients with yang-heat constitution, damp heat constitution constitution and phlegm-dampness constitution not to eat cinnamon, so as not to aggravate discomfort.

Compared with yang deficiency, most patients with yin deficiency are often thirsty, always drink water or feel dry mouth, and sweat easily when sleeping, which is called "night sweats due to yin deficiency". I recommend a medicine for nourishing yin, Dendrobium. Dendrobium is sweet, cool and moist, and has a good effect of nourishing yin. People with dry mouth can make tea with Dendrobium 10g and green tea 4g, and the effect is very good. In addition, lily is also a good medicine for nourishing yin. Children can eat porridge cooked with rock sugar and lily, and adults with tuberculosis can cook porridge with fresh lily and lotus seeds, which has a better effect of nourishing the heart and calming the nerves.

If you sweat a lot in summer, Chinese medicine believes that it is caused by deficiency of both qi and yin, and excessive sweating will aggravate the consumption of qi and yin. I recommend a famous prescription called "Shengmai Drink", which consists of only three herbs: Dangshen, Ophiopogon japonicus and Schisandra chinensis. These three herbs are very cheap and easy to buy, and can be bought in ordinary Chinese medicine shops. If you don't want to cook it yourself, pharmacies have ready-made Chinese patent medicines for sale, and the price is reasonable and the effect is very good.

Yin-yang imbalance is also the cause of many high-incidence and common diseases. Just to name a few diseases, such as hypertension, coronary heart disease and diabetes. Are closely related to the imbalance of yin and yang in human organs. There is a saying in Huangdi Neijing that "Yin Pingyang is the secret", in which "Ping" means balance and "Secret" means firmness. If the yin is balanced and the yang is dense, then the body will be healthy and the spirit will be sufficient; When yin and yang are out of balance, diseases follow. If there is a slight imbalance between yin and yang, people will have sub-health symptoms; If yin and yang are moderately unbalanced, people will suffer from general diseases; If there is a serious imbalance between yin and yang, people may get seriously ill.

Now everyone should understand the importance of maintaining the balance of yin and yang in the body. So, what aspects should we pay attention to in our daily life?

First of all, we should pay attention to the balance between cold and heat. Why? Because cold hurts yang and heat hurts yin, if the balance between cold and heat cannot be maintained well, it will inevitably affect the balance between yin and yang. As mentioned earlier, a principle of TCM treatment is that cold is hot and hot is cold, which means the balance between cold and heat. It is hot in summer, so it is suitable for drinking cool mung bean soup to relieve summer heat. It's cold in winter, and a bowl of hot noodle soup will make people feel comfortable. Keeping the balance between cold and heat in the diet is a wonderful way to adapt cold and heat in the body.

Secondly, we should keep the balance of qi and blood. Because qi belongs to yang and blood belongs to yin, it is very important to maintain the balance of yin and yang in the body. Because everyone has different degrees and characteristics of qi and blood disorders, the methods adopted are also different. Mild people can use diet, herbal tea and massage, while severe people can use moxibustion, acupuncture and traditional Chinese medicine. Of course, the most important thing is to be calm and stable.

Third, we should pay attention to the balance between dry and wet. We have 70% water in our bodies. If we lack water in our body, there will be insufficient body fluid, which is manifested as dry mouth, constipation, dry skin and other symptoms. In addition, the water in the human body should not be too much, and too much water will cause diseases such as "water poisoning".

Through the balance of cold and heat, qi and blood, dryness and dampness, the body maintains a relatively stable balance of Yin and Yang Can. When yin and yang are in balance, our bodies will be healthy.
