The meaning of the method of promoting blood circulation and nourishing yin and muscle growth is to treat sores and ulcers that do not close after ulceration for a long time by promoting blood circulation and nourishing yin and fluid. 1. All treatments that eliminate stagnation, regulate blood circulation, and clear the blood channels are known as the method of clearing the blood channels. The method is based on the spirit of “dredging the blood and qi, making it organized and peaceful” and “the blood should be resolved when it is solid”. 2. The treatment of sores and ulcers that do not converge is called the method of nourishing the yin to nourish the yin fluid and improve the state of yin deficiency. This method is based on the principle of “moisturizing the dry”. If you are not feeling well, you should go to the hospital in time to get a clear diagnosis and have your doctor arrange a treatment plan, rather than taking it lightly or treating it on your own, so as not to delay your condition.
