”Relieving spasm and treating pain” is an important rule of Professor Fang Dingya in treating spastic pain. However, “relieving spasms and treating pain” has not yet been elevated to a major treatment method, and is only reflected in some prescriptions, such as peony and licorice soup to relieve pain, yuzhen san to relieve spasms and pain, and barley to relieve pain. It is only reflected in some prescriptions, such as Paeonia lactiflora and Glycyrrhiza glabra to relieve pain, Yu Zhen San to relieve spasm and pain, and Job’s Tear to relieve acute contracture of tendons. For example, biliary colic, renal colic, gastrointestinal colic, etc., all use atropine to relieve spasm and pain, which can be considered one of the rules of pain treatment in Western medicine. The room teacher pointed out that whether it is tendon contracture, smooth muscle spasm, transverse muscle spasm, organ spasm can cause pain, such as ankylosing spondylitis is tendon spasm pain, excessive exercise or calcium deficiency is transverse muscle pain, intestinal spasm is smooth muscle spasm pain, bile and kidney stone evidence is organ spasm pain, this pain is characterized by severe pain, traction pain, vibration pain, and often in the limited signs. Giving herbal medicine to relieve spasm and treat pain has remarkable efficacy. In view of the fact that the pain symptoms are caused by the spasm pathology and the antispasmodic method has significant curative effect, Master Fang suggested to establish another antispasmodic method in the treatment rules, which is listed among the warming of menstruation, dispersing cold and relieving pain, relieving heat and relieving pain, and relieving qi and relieving pain. Since there is a rule of antispasmodic treatment of pain, of course there is an antispasmodic herbal medicine, and it is necessary to have a separate category in herbal medicine, so that it is convenient for scholars and users. According to some literature and current research on Chinese medicine, as well as clinical experience, Master Fang believes that the following herbs have antispasmodic functions: Bai Shao, Ge Gen, Wei Ling Xian, Centipede, Silkworm, Cicada, Scorpion, Shi Wei, Ephedra, Yang Jin Hua, Gui Zhi, Job’s Tear, Tian Nan Xing, etc. These drugs have different effects on different tissues and different pains. These drugs have different antispasmodic and analgesic effects on different tissues, different organs and different parts of the body, so the doctor can select the drugs according to different characteristics and implement antispasmodic and analgesic treatment. In the case of coronary angina, some patients are caused by coronary artery spasm, which is also one of the important pathogenesis of coronary artery disease. Spasm can occur on the basis of atherosclerosis or at sites where no obvious pathological changes are seen, due to local release of vasoconstrictor substances such as 5hydroxytryptamine or thromboxane A2 by platelets, which stimulate vascular smooth muscle, smooth muscle spasm, vasoconstriction, which in turn leads to narrowing or occlusion of one or more coronary arteries. Clinically, Prinzmetal variant angina is caused by severe coronary artery spasm, and the ECG shows the manifestation of transmural myocardial ischemia, i.e. ST-segment elevation, which can return to normal when the spasm is relieved. Sui? As early as 610 A.D., Chao Yuanfang pointed out, “Those with rapid heart pulse are suffering from heart pain leading to back pain.” (Treatise on the Origin of Diseases? This indicates that Chinese medical practitioners recognized as early as 1400 years ago that heart pain can be caused by the contracture of the heart chakra. Therefore, relieving spasm and treating pain can be one of the treatments for coronary artery spasm type angina pectoris. Clinically, there are three common causes of coronary artery spasm: First, emotional factors. It is not uncommon for angina pectoris to be induced by emotional stress. Epidemiological studies have shown that Type A personality, which is characterized by an impatient, aggressive and competitive temperament, preoccupation with work without rest, and forcing oneself to strive for achievement, is one of the important risk factors for this disease. “All tyrannical and strong and straight belong to the liver” “the liver is the master of the fascia” “the heart is the master of the blood” “the pericardium is the master of the heart’s veins “Therefore, it is suggested that the fascia of the human body is dominated by the liver, and the fascia is all over the body, such as the inner and outer membranes of the blood vessels and the inner and outer membranes of the organs are all fascia, which are closely related to the liver and depend on the moistening of liver blood and the regulation of liver qi. Anger and injury to the liver or emotional disorders and depression of liver qi can lead to loss of harmony of liver qi and blood, unfavorable drainage and loss of moistening of tendons and veins, resulting in contracture of tendons and veins. Clinically, the onset of this type of coronary artery spasm type angina is characterized by: chest pain often triggered by excessive emotion or depression, mostly accompanied by chest tightness, good breath, two hypochondriacs, etc., pulse string. The author treated an elderly female patient with coronary artery disease who was admitted to the cardiovascular ward with “paroxysmal anterior heart pain for more than 1 year, aggravated for 1 month” and diagnosed with “unstable angina”. After admission, he was treated with dual antiplatelet, nitrate, β-blocker, angiotensin-converting enzyme inhibitor, lipid-lowering drugs, and anticoagulant according to the treatment guidelines for unstable angina, but the angina was still frequent, with severe and long-lasting chest pain, which could be relieved by direct intravenous injection of large doses of nitrate during the attack. When asked about his medical history, the patient was impatient and irritable, and was unhappy all day long. The chest pain often came on suddenly when he was angry with his family or during sleep at night, with fullness in both sides, red face and dry eyes, red tongue, thin yellow fur, and string pulse. Considering that the diagnosis is “liver qi discomfort, heart vein contracture”, so on the basis of benefiting qi and activating blood, we add softening liver and soothing liver, relieving spasm and pain. After taking the medicine, the angina was gradually relieved and no more attacks of angina at night. Second, cold stimulation. Clinically, the incidence of coronary angina increases in winter and early spring when the climate is cold. The reason for this is that low-temperature stimulation leads to sympathetic excitation of the body, the release of norepinephrine and other vasoconstrictive substances, causing spasm of the coronary arteries, thus triggering coronary heart disease. As early as more than two thousand years ago, Chinese medicine has discussed the pain caused by the tendons and veins contracture due to cold, such as “Su Wen? Raise pain theory: “cold guest in the pulse outside the pulse cold, the pulse cold is shrinkage m, shrinkage m is pulse dull and urgent, dull and urgent is outside the small complex, so suddenly and pain.” Su Wen? The regulation of the meridian: “cold accumulates in the chest and not diarrhea, not diarrhea is warm to go, cold alone stay is blood condensation and weeping, condensation is the pulse does not work.” The above two paragraphs clearly point out that cold is one of the main causes of pain caused by contracture of the heart veins. For such patients, it is appropriate to use the method of warming the Yang and dispersing the cold, relieving spasm and relaxing the tendons. The third is pain caused by plaque instability, inflammatory stimulation and vascular smooth muscle spasm. Due to the rupture of unstable atherosclerotic plaques in coronary arteries, platelets are activated, platelets adhere, aggregate and interact with vascular endothelium in a complex way, releasing various vasoconstrictive substances such as thromboxane A2, platelet activating factor 4, endothelin, 5hydroxytryptamine, etc., causing spasm of vascular smooth muscle, lumen narrowing, and angina pectoris due to decreased blood flow in coronary arteries. Since coronary artery spasm is one of the important links in the development of coronary angina, then the antispasmodic pain relief method has a place in its treatment, in this regard, Western medicine uses nitrates and calcium channel blockers to release vascular smooth muscle spasm and dilate blood vessels; while in Chinese medicine, it can establish the method of “antispasmodic treatment of pain”, using Chinese medicine to relieve spasm and pain. The author draws on the method of relieving spasm and pain in the treatment of ankylosing spondylitis by combining antispasmodic and analgesic drugs to treat coronary spasm angina on the basis of benefiting Qi and activating Blood. The basic formula is: Raw Astragalus, Radix Codonopsis, Radix Rehmanniae, Rhizoma Chuanxiong, Radix Angelicae Sinensis, Radix Paeoniae, Radix Puerariae Sinensis, Radix Paeoniae Alba, Radix Glycyrrhiza Uralensis and Radix Wei Ling Xian. In this formula, raw Astragalus and Radix Codonopsis are combined with Si Wu Tang (Radix Rehmanniae, Chuanxiong, Radix Angelicae Sinensis and Radix Paeoniae Alba) to benefit Qi and invigorate Blood, while Pueraria Mirifica, Radix Paeoniae Alba and Radix Glycyrrhiza Uralensis are used to relieve spasm and pain. Pharmacological studies have shown that Pueraria Mirifica can significantly dilate normal and spastic coronary vessels, inhibit smooth muscle cell proliferation, improve myocardial blood supply in ischemic areas, and is strengthened with increasing doses. White peony is “sour to nourish the liver” and licorice is “sweet to slow down the tendons”. The combination of the two is effective in slowing down the pain, and is often used for painful tendons. The effect of Paeonia lactiflora and Glycyrrhiza glabra is not only on the skeletal muscles of the body and limbs, but also on the deeper, smooth muscle tissues and organs, such as the gastrointestinal tract, trachea, bile duct, uterus, bladder, urethra or vascular smooth muscle, etc. It can relieve their contractures and stop their pain. It has the effect of dispelling wind-dampness, opening up the meridians and stopping paralysis and pain, and is often used by masters to relieve the contractures of tendons and veins. Modern pharmacological research has confirmed that wei ling xian contains bai tai wong xin and bai tai wong alcohol, saponins, etc., which have anti-inflammatory, analgesic and smooth muscle relaxation effects. Clinically, it also needs to be added and reduced flexibly according to the individual patient’s condition. If vascular ultrasound or angiography indicates heavy atherosclerotic plaque or even severe stenosis, and if the plaque is unstable or ruptured, leading to coronary spasm and angina pectoris, anti-inflammatory and detoxifying products are often added to the plaque, such as forsythia, Xia Gu Cao, Yu Jin, Gua Cao, Allium, and if necessary, Andrographis paniculata, white mustard seed, soapberry, etc. to disperse the knots; if the spasm is heavy and the pain is prolonged, worm medicines can be added, such as Wu Zhi Snake, Centipede, Scorpion, Di Long, Cicada, etc. If the spasm is heavy and the pain is prolonged, we can add worm medicine, such as centipede, centipede, whole scorpion, dragon, cicada, piercing nail, etc. They all belong to the wind medicine of worm medicine, pungent can open the channels, salty can soften the hardness, have the function of attacking the hardness and breaking the accumulation, invigorating the blood to dispel blood stasis, passing Yang and dispersing the knots, relieving spasm and pain.
