Why is it called Danshen? In fact, it has a history. It is said that a man visited a famous doctor to save his dying mother, and finally asked for medicine blindly. So he crossed mountains and seas and finally found this medicine. After taking the decoction to my mother, my condition has greatly improved. It turns out that his mother suffers from blood stasis, and this medicine has a good effect of promoting blood circulation and removing blood stasis. People praised the filial son's behavior very much, so they named this medicine "Dan Xin". Now Danshen is still called Dan Xin in many places.
"Shen Nong Ben Cao Jing" contains Danshen: bitter in taste, slightly cold. Treat evil spirits in the heart, faint bowel sounds like running water, cold and heat accumulate, break the disease and eliminate the new, and replenish qi. Salvia miltiorrhiza is cool and red, which can enter the heart and clear the heart. Heat in the heart leads to irritability, while fire obstructs the chest and leads to fullness in the chest. Therefore, Salvia miltiorrhiza can relieve annoyance and depression, and dispel blood stasis and heat toxicity in the heart and abdomen. Accumulation and abscess are pathological products of blood stasis accumulation. Salvia miltiorrhiza can be used in combination.
Heart pulse stasis is the poor blood circulation in the body, so the formation of blood stasis can stay in all parts of the human body and show different symptoms. If blood stasis stays in the heart pulse, it is blood stasis in the heart pulse.
The most common symptom of heart congestion is pain. The pain is located in the precordial area, and there is heart and lung in the chest. Pain in precordial area is called "chest obstruction" in Chinese medicine, and obstruction cannot be achieved. Of course, there are many reasons for chest pain, such as phlegm, drinking and qi, and blood stasis is one of them. Many modern diseases can be manifested as chest pain, and the most common is coronary heart disease.
The stagnation of heart pulse is characterized by stabbing pain, such as acupuncture, and the painful part is generally unchanged, so-called "pain does not move." Blood belongs to yin, and yin is dominant at night. Therefore, most of the pain caused by stagnation of heart pulse will be aggravated at night. Similarly, coronary heart disease also occurs more at night and the pain is aggravated.
When blood stasis stays in the heart pulse, the qi will be blocked by blood stasis, so it will show the symptoms of chest tightness. Similarly, chest tightness will increase at night. "synopsis of the golden chamber" contains: "the patient's chest is full, his lips are soft and his tongue is blue, and his mouth is dry. He wants to rinse his mouth and doesn't want to swallow it. It's neither cold nor hot, the pulse is a little late, and the abdomen is dissatisfied. His people said I was full because of blood stasis. This is an earlier discussion on chest tightness caused by blood stasis.
Blood stasis stays in the heart vein, new blood production is blocked, and the heart lacks blood nourishment, so it will be manifested as palpitations, dreaminess and insomnia. Blood stasis prevents the mind from returning to its place, and qi floats outward, which is manifested as insomnia, which is also the reason why Xuefu Zhuyu Decoction can treat insomnia.
Salvia miltiorrhiza is an important Chinese medicine for promoting blood circulation and removing blood stasis, so it can treat chest distress, chest pain, insomnia, dreaminess and palpitation caused by blood stasis. The commonly used prescription is Danshen Yin, which is Danshen combined with Sandalwood and Amomum villosum to treat heart pulse stasis. Similarly, salvia miltiorrhiza is good, but it can't be abused. Now many doctors use salvia miltiorrhiza when they see chest tightness and chest pain, regardless of cold and heat. It is really influenced by western medicine. They believe that coronary heart disease is caused by blood stasis, and that TCM without syndrome differentiation is a body without soul.
