Astragalus is widely used in various clinical departments, known as “ten drugs eight astragalus”. First of all, the origin of the name of Astragalus, Astragalus is the root part of the medicine, cut open to show yellow-white, so the word Astragalus yellow by the color to name. Astragalus, in the ancient materia medica for “Jie”, is the meaning of long, the Qin and Han dynasties people may think that this medicine is the first qi tonic, is a tonic among the elders, so named Huang Jie, later to facilitate the writing, the name changed to Huang Qi. Astragalus is produced in Inner Mongolia, Shanxi, Gansu, Heilongjiang and other places, the dried root is used medicinally. Cultivated or wild. Sweet in taste and warm in nature. It belongs to the lung and spleen meridians. Its effects are to tonify the qi and fix the surface of the body, diuretic to promote toxicity, drain pus, and astringent to sores and muscles. Effects Astragalus exerts its effects on the treatment of coronary heart disease in 2 main ways. 1, has the function of nourishing qi coronary heart disease in Chinese medicine is “chest paralysis” category. Coronary heart disease patients are mostly induced by exertion, cold, moving is depleted qi, cold is injured yang, heart yang deficiency is the main aspect of its pathogenesis. Whether patients with coronary heart disease are suffering from blood stasis, qi stagnation, yang deficiency or yin deficiency, all of them have the pathological changes of qi deficiency. Therefore, the treatment of coronary heart disease should focus on replenishing Qi. “Qi is the marshal of blood, and when Qi is moving, blood is moving, and heart Qi is the basic driving force of blood circulation. Dijing cloud: “loss of its heart, regulate its Ying and Wei”, the spleen and stomach in the center of the focus on gas, Ying and blood to produce. Astragalus tonic qi returned to the lung, spleen, good at replenishing the Ying and Wei qi, the most important in the treatment of coronary heart disease. 2, has the effect of detoxification, decay and myogenesis Some patients with coronary heart disease have serious coronary artery lesions, such as three coronary artery lesions can not be treated with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG); or by PCI or CABG after the vessel is narrowed again and can only take internal drug therapy to promote myocardial tissue capillary neovascularization and the opening of the collateral circulation to increase myocardial blood perfusion. In traditional medicine, the method of decomposition and myogenesis is one of the common treatments for surgical sore diseases, and its method not only promotes the growth of new sarcomeres, but also promotes the neovascularization of blood vessels. Therefore, in the clinical treatment of coronary artery disease, the method of myogenesis can be used to increase coronary capillary neovascularization, thus promoting the establishment of coronary collateral circulation. This Jing Shuzhi said: “Astragalus a source of three factions, dredge the root of the three jiao, the benefit of the Ying and Wei Qi, so where the Ying and Wei between the obstruction, all pass, the so-called source of clear flow from the clean.” It can be seen that in addition to the effect of astragalus tonic Qi, also has the effect of detoxification, decay and muscle growth. The use of raw astragalus 30-60g, can be the effect of decomposition and regeneration of muscle. The case of small example of course, the treatment of coronary heart disease is far from enough with a single medicine Huang Qi. Let’s look at a case of a patient with coronary heart disease first. The patient is male, 62 years old, first diagnosed on May 13, 2014. The patient had a sudden feeling of suffocation in the heart and chest, general weakness and profuse sweating on November 6, 2010. He was diagnosed with “coronary artery disease” at the local hospital. The angiogram showed 70-80% stenosis of the middle left anterior descending branch, 50-70% stenosis of the right ileal branch and left ileal branch. The patient was given conventional treatment with western medicine by the internal medicine department. At present, the patient feels suffocated in the precordial region every time he is tired or when the weather changes, and he is usually short of breath, weak, afraid of cold, and has poor appetite, slightly dilute stools, sleep is possible, the tongue is fat, with a dark texture and thick white coating, the root of the tongue is slightly yellow, and the pulse is sunken and thin. This Chinese medicine diagnosis is chest paralysis, with evidence of Qi deficiency and mutual obstruction of stasis and phlegm. Treatment: Benefit Qi, invigorate Blood, and resolve phlegm. Herbs: Astragalus membranaceus 30g, Rhodiola rosea 30g, Psidium guajava 30g, Allium sativum 20g, Radix Panax notoginseng 10g, Huanxiong 15g, Rhizoma Chuanxiong 15g, Safflower 15g, Salvia miltiorrhiza 15g, Radix Paeonia lactiflora 20g, Rhizoma Atractylodis Macrocephalae 15g, Rhizoma Huanglian 5g. 12 doses in water, one dose daily. After taking 12 doses, the symptoms of chest tightness and shortness of breath improved. After taking 24 doses, the patient’s condition was stable, chest tightness, shortness of breath and weakness disappeared, and general physical activities were no longer affected. The above patient has a deficiency of heart yang and weakness of spleen qi, and the yin evil, such as water and phlegm, takes advantage of the deficiency to take advantage of the yang position, so that the evil and the positive fight each other and the chest yang is blocked, causing discomfort in the precordial area and chest tightness. In addition to the manifestations of deficiency of heart yang and weakness of spleen qi, there are also signs of heat caused by mutual obstruction of phlegm and stagnation of blood, such as dark tongue, yellowish coating on the tongue root and obvious veins under the tongue. In addition to using Astragalus membranaceus with Chuanxiong, Safflower, Salvia, Radix Paeoniae Alba, etc. to invigorate blood circulation and remove stasis, it is also necessary to use pungent and dry products such as Guahua, Allium and Huo Xiang to remove phlegm and dampness from the body. “The spleen is the source of phlegm production. The combination of Atractylodes Macrocephala to strengthen the spleen and elevate the qi flow will help to dispel phlegm, resolve phlegm and prevent phlegm-dampness from growing inside. For phlegm and stagnant heat, a small amount of Huang Lian is used to remove damp-heat in the middle jiao.
