Traditional Chinese medicine believes that a person's yin can only supply a life span of 30 years, so our yin has long been lost. Then, it is logical to prolong life, keep healthy and replenish the lost Yin Qi.
Nutrition believes that people's diet should be as far away from their own species as possible, that is, pigs, cattle and mutton with four legs are not as good as chickens, ducks and poultry with two legs, and poultry with two legs are not as good as fish without legs. The reason for this is mainly from the fat content of food. We say that people tend to get fat after middle age, but this kind of "happiness" does not mean health. So after this stage, try to eat foods with low fat content, so that people will not gain weight easily and have fewer complications, such as hypertension, cardiovascular and cerebrovascular diseases, diabetes and so on. Coupled with the middle age of modern men, due to the pressure of society and other aspects, coupled with family relations, the body is easy to "get angry", so neurasthenia, insomnia and other diseases also follow, consuming the yin essence in the body.
It is often said that men over 40 are often untenable in front of sex life. To put it bluntly, that is to say, men over 40 need to tonify kidney and strengthen yang. Chinese medicine believes that after the age of 40, the innate essence basically disappears, and it depends entirely on the acquired essence of Shuigu to maintain itself. Kidney stores essence, and essence produces marrow. Kidney essence is not concerned about its surplus, but afraid of its deficiency, so it must be well supplemented.
So how should we supplement these deficiencies or lost "essence" to the body? There was a famous doctor named Qian Yi in the Song Dynasty in China. Poria cocos, Alisma orientalis, Radix Rehmanniae Preparata, Cornus officinalis, Cortex Moutan and Rhizoma Dioscoreae constitute a classic prescription for tonifying kidney, which is our present Liuwei Dihuang Pill. Men over 40 years old, even if they don't have chronic diseases, take two pills of Liuwei Dihuang every day, which can also avoid excessive exhaustion of yin essence and prolong life.
