In Zhang Xichun's "Medical Hearts in Chinese and Western Records", there is a very detailed discussion on the subsidence of the atmosphere, especially the Shengzao Tang, which is simply superb and has saved many critically ill patients. In Dr. Luo's audio, he also vividly described many medical cases of atmospheric depression. As a medical enthusiast of science and engineering, I use the principles of mechanics to understand atmospheric depression and ascending depression.
The atmosphere is stored in the chest, and the heart and lungs are suspended in the chest. The chest cavity is airtight, similar to the cabin of an airplane. The pressure in the cabin must ensure the comfort of passengers, and the pressure in the chest cavity must also ensure the normal work of the heart and lungs. Therefore, there is pressure in the air in the thoracic cavity, which can just offset or be slightly greater than the weight of the heart and lungs. The beating of the heart and the breathing of the lungs both contract and expand. In the lifting state, these two movements are very easy; if the strength of the lifting is not enough, the heart and lungs will inevitably sag under their own weight, and surface tension will be generated on the surface of the heart and lungs, contracting and expanding It becomes difficult, and people will feel chest tightness, breathlessness, palpitations, etc.
This is like blowing up a balloon. A child in a natural state can blow up a balloon in a few breaths; if you fill the balloon with half a bowl of water and hang the balloon vertically, it is equivalent to the heart and lungs without the air in the chest. In a state of sagging under its own weight, it is very difficult to blow up the balloon again. This is because the weight of the water creates tension on the surface of the balloon, and the balloon can only be blown up if the force of blowing it is greater than the surface tension.
The "Huangdi Neijing" said: "The air enters the viscera and dies without disease", which means that the air in the chest sinks severely, even sinks below the chest cavity, enters the abdominal cavity, and the heart and lungs completely lose their lifting power, causing breathing to stop and the heart to stop suddenly. The person had no other symptoms and died suddenly.
Astragalus is the main medicine in Shengxian Decoction. Astragalus is the best at invigorating qi, and at the same time it is good at raising qi. The temperament is very light and rich in oxygen. The composition is the same as the atmosphere in the chest, which is exactly the same as Qi. ; and then use cornus, which is best at restraining and can prevent the slackness of Qi.
The whole prescription of Shengxian Decoction costs 13 kuai, which is equivalent to 39 grams now. They are all common Chinese medicines. I have bought 3 pairs of them, and the total cost is more than 7 yuan. These 3 medicines were given to my mother. She has had it for two or three years, and every now and then she wants to lift her breath hard and snort loudly, but other places are not uncomfortable; according to her, several old ladies have this problem, but It's okay, and I haven't been to a doctor. After spending less than 8 yuan, my mother's humming problem completely disappeared. It's amazing!
