The original text is: "Standing at forty, Yin Qi is half, and the day is declining." It means that by the age of 40, the essence in the kidney will be attenuated by half, and the "Yin Qi" here refers to the kidney qi. Chinese medicine believes that kidney controlling water is the foundation and congenital root of five internal organs. In other words, the amount of kidney qi when a person is born basically determines the rise and fall of his five internal organs and the length of his life.
Besides, "40" is an imaginary number. Male kidney qi declines around 40 years old, while female kidney qi begins to decline from prosperity around 35 years old, showing alopecia, tooth decay and facial dryness. Kidney qi includes kidney essence, kidney yin and kidney yang, so there are three kinds of kidney qi damage.
Some people begin to show signs of virtual fire after 40 years old. This kind of people need to nourish yin because of kidney yin damage, which is common in women. They should eat less spicy and spicy things, such as onions, garlic, peppers, alcohol and so on. It is suggested to play Tai Ji Chuan at ordinary times and take a walk in the shade. In terms of diet, they can choose sea cucumber, soft-shelled turtle, mushroom, mulberry, fungus, black bean, medlar, Ligustrum lucidum and so on.
If the condition is serious, use Baizhi Dihuang Pill; If accompanied by dizziness, Qiju Dihuang Pill can be used for conditioning. While some people show yang deficiency, such as nocturnal urination, chills, cold limbs, heavy cold and dampness, etc., and can take Jinkui Shenqi Pill.
Others have insufficient kidney essence due to sexual overwork or excessive brain use, which is manifested as dizziness, backache, dull complexion, insufficient essence and fatigue. They can eat more beef and mutton, deer glue, Placenta Hominis, Radix Rehmanniae Preparata, Lycium barbarum and so on. Lycium barbarum and Chinese yam beef soup has a good effect of invigorating kidney and essence. It can be fried alone or added with Polygonatum sibiricum and Radix Rehmanniae Preparata, which is suitable for both men and women. Lycium barbarum and mulberry are soaked in water instead of tea, and the effect is also good.
Modern people's living conditions are good, and the time of kidney qi decline will be delayed than that of the ancients;
According to years of clinical observation, this is not the case. If modern people look younger than the ancients in those days, it is more in clothes and beauty, and there is not much difference in the internal aging speed. On the contrary, many lifestyles of modern people are accelerating the loss of kidney qi, such as indulgence, excessive indulgence, overeating, staying up late for a long time, overeating and so on.
In order to "retain youth", some people take some wrong practices, such as men abusing aphrodisiacs and women wearing cosmetics containing hormones, which are more harmful to the body and even increase the risk of cancer. The ancient emperor had been taking supplements all his life, but because of his concubines in three palaces and six courtyards, his life span was not long, so it can be seen that conforming to the laws of nature is the real way to keep in good health.
