My teacher Zhang has a deep understanding of this. He said: "Spring is spring, summer is long, autumn is harvest, and winter is hidden" is the normal law of the four seasons in nature. The human body should obey the natural changes of yin and yang in the four seasons, achieve the balance of yin and yang, and harmonize qi and blood in order to live a long and healthy life.
In terms of taking life, his view is that the four seasons are dominated by ups and downs in spring and summer, with warm spring and hot summer, and its nature belongs to yang; Autumn and winter are dominant, autumn is cool and winter is cold, and the essence is yin. As far as the human body is concerned, the sun's spirit should have risen in spring and summer, but the sun's spirit is abundant outside and deficient inside; The order of autumn and winter is that yin rises, yin is abundant outside, but empty inside. Therefore, he advocates that ordinary people should eat spicy and cool food in spring and summer, but in order to raise yang, they should avoid eating too cold food. For example, overeating is cold and cold, damaging the yang, abnormal transport and transformation, and improper lifting methods are prone to abdominal pain and diarrhea. Be careful to eat too much warm food in autumn and winter, and eat sweet and cold food to nourish yin. Northerners, who have lived in cold places for a long time, are fat and strong, dense in texture, strong in yang, and like to eat spicy and strong wine, so they are depressed inside and hot inside.
In the aspect of syndrome differentiation and treatment, Zhang Lao believes that to be a good doctor, we should not only be familiar with the changes of Yin and Yang in the four seasons, but also master the ups and downs of Yin and Yang in patients' qi and blood, so as to achieve accurate syndrome differentiation and correct treatment of Yin and Yang. So when treating patients, don't stick one end. If the body is yang deficiency, it is easy to recover in spring and summer, and it is easy to play in autumn and winter. Its treatment needs to be supplemented in summer when the sun is strong, and its symptoms can be alleviated or delayed in autumn and winter; If the body is full of yang, the disease is prone to drama every spring and summer, and its treatment should not add warm products to the fire, but use sweet and cold products to make the fire more prosperous and make the yang level. As the saying goes, "Yang Can cannot be secret, Yin Qi is absolute, Yin Pingyang is secret, and spirit is rule".
Similarly, patients with yin deficiency are prone to dizziness every winter and spring. This has long been recorded in Zhongjing's book. For example, in the synopsis of the golden chamber, blood stagnation and fatigue, it is said: "fatigue is a disease, with a large pulse, troublesome hands and feet, spring and summer dramas, autumn and winter cups, yin and cold essence, and acid must not be cut." Although the disease is easy to recover in autumn and winter, it is easy to fight in spring and summer. However, if you give nourishing liver and kidney products in autumn and winter, you can often slow down the recurrence in spring and summer or alleviate its symptoms. This is the meaning of the so-called "essence stored in winter, not sick and warm in spring" in Neijing.
Knowing this, our health, disease prevention, treatment and medication are all subject to the natural changes of Yin and Yang in the four seasons and adjusted according to the ups and downs of human qi and blood. Then the Dafa is clear and it is easy to avoid delay.
