Hello everyone, I am your TCM, Xiao Liu.
Forty years old, and most of the yang qi is also decaying; it means that after the age reaches forty years old, the yang qi of the body will be reduced by half, and the body will begin to slowly move towards the stage of decline.

Chinese medicine believes that "the waist is the house of the kidneys", the position of the kidneys is located on both sides of the waist, therefore, the waist is the area covered by the yang of the kidneys, the yang is sufficient, then the lumbar spine is strong and powerful, if the yang is insufficient, the lumbar spine is vulnerable to injury.
In life, when encountering rainy weather, there will be pain in the waist, and if the organic problem is excluded, the low back pain is related to kidney deficiency.
There are many root causes of kidney deficiency in life, in addition to waist and leg pain, long-term staying up late, alcoholism and smoking will hurt the function of the kidneys.
Zhang Zhongjing: Mastering the "trilogy" of life, when you are old, you can also practice the "way of husband and wife", so that the yang of the body returns and the kidneys look young.
A step: massage the kidney Yu points
It is located at the waist of the human body, first touch the lower edge of the ribs with your hands, and at the side waist, draw a horizontal line along the lower edge of the ribs, and cross over the muscles on both sides of our waist, which is the kidney Yu point.
Method: After rubbing the hands warmly, gently rub the kidney Yu acupuncture points about 50 times, alternating between the two sides of the waist, insisting on it for several months, it has a good effect on the problems in the waist.
Two steps: Eat more foods containing "zinc"
Chinese medicine often says that "the people take food as the sky", the kidneys are like the "engine" of the car, only to ensure that the engine does not fail, the car can drive normally, the kidneys are the same, regularly give substance supplements, in order to ensure that it can operate normally.
According to the man's private recipe left by Hua Tuo, prepare 10 goji berries, 3 grams of Lang Ling Shan ginseng, 5 grams of huangjing, 3 grams of astragalus; after the above ingredients are prepared, put them into the cup and boiling water and bracing, one dose a day, which is of good help for kidney deficiency caused by wilting, lack of time, waist and leg pain, hair loss and prostate.
Early in the "Shaanxi Herbal Medicine" there is a record: Lang Ling (kuang) mountain ginseng is rich in plant alcohol zinc, manganese and saponins and other elements, perennial growth in China's Jilin region, due to the particularity of the growth environment, small, shaped like a broad bean size, can help the initial swelling of the prostate, is figuratively called "man root".
Trilogy: Everyday Habits
Many people have bad habits in life, such as sitting for a long time, staying up late and drinking heavily, etc., and we adjust our lifestyles to stay away from these bad habits.
You can often do some waist activities to enhance the motivation of the waist, and when encountering cold climates, you must avoid the waist from wind, cold and wetlands, and pay attention to the warmth of the waist.
In short, the kidney is the "root of life" of men, only the kidney will be better, as long as the man protects the waist first, the kidney will be good, and the waist is not good equal to the kidney is not good.
