Basically everyone has experienced mouth ulcers in daily life, and many times mouth ulcers are not taken seriously because, according to their own experience, they will get better on their own after a few days, so just put up with it. There is also a key issue, the current lack of particularly effective treatment measures for mouth ulcers, in view of this situation, with mouth ulcers, often rely on the body’s self-recovery self-healing. Although the mouth ulcer is a small disease, but the pain is not small, the mouth Zizi La La pain, this pain is like a shadow, can not be dispersed, do not dare to eat a big mouth, do not dare to eat spicy, and even do not dare to open the mouth to speak. This pain will further affect the mood, easy irritability and anxiety, feel particularly tired body, if encounter recurrent mouth ulcers, old disease is not removed, the new disease is born, more painful, really can be called a small problem big pain. Chinese medicine actually has very good curative effect on mouth ulcers. Chinese medicine focuses on evidence-based treatment, and often takes different treatments and prescriptions for different patients. The specific embodiment of the discriminatory treatment in clinical practice is the theory, method, prescription and medicine, of which the reason occupies the primary position. “The “theory” is to analyze, summarize, and identify the disease evidence by using the information obtained from the four clinics, and then lay a good foundation for legislation, prescription, and drug selection. The essence of diagnosis and treatment lies in this “reasoning”. Su Wen. The “Supreme Truth” “all pain and itchy sores belong to the heart (fire)”, from this point of view, the identification and treatment of mouth ulcers can start from the “fire”, about mouth ulcers “on fire” said The “fire” of mouth ulcers has a very deep base of popular understanding among the people. The actual evidence (fire) and the deficiency evidence (fire) can be distinguished by observing the tongue and pulse, so in the process of treating mouth ulcers and removing the fire, bitter and cold heat-clearing drugs such as Huanglian, Scutellaria, and Daxing leaf cannot be used. The disease will not be cured. Modern medicine believes that the occurrence of this disease is related to the decline of immunity, and the theory of Chinese medicine also believes that this disease is related to the lack of vital energy, so the key to this disease also lies in internal treatment. If the internal cause is not removed, the external treatment alone cannot eliminate the cause of the ulcer from the root. Combining the patient’s symptoms as well as the characteristics of tongue and pulse, mouth ulcers mainly start from the four organs of heart, liver, spleen and kidney, and regulate cold and heat deficiency. The clinical practice generally divides mouth ulcers into the following types of evidence: 1, the spleen and stomach contains heat type: these patients are generally accompanied by fever, red face, dry mouth, bad breath and constipation, urine yellow and other symptoms, the tongue red coating yellow pulse slippery, the treatment is to clear heat and fire, cool blood to relieve pain. 2, heart fire on the inflammation type: this type of patient ulcers mostly occur in the tip of the tongue, red, burning pain, accompanied by heart trouble, dry mouth, short urine, insomnia and other symptoms, the tongue red coating yellow pulse number, the treatment is to clear the heart to lower the fire, cool the blood and diuresis, you can refer to the guide Chi San with the symptoms of the addition and subtraction. This type of mouth ulcer is more common in female patients, and mouth ulcers often accompany the menstrual cycle, occurring before or during menstruation, and are related to changes in estrogen levels during the menstrual cycle; sometimes they are also closely linked to emotional changes, and mouth ulcers are often accompanied by irritability, chest distension, bitterness and dryness of the throat, insomnia, breast swelling and pain in the premenstrual period, and irregular menstrual cycles. . The tongue is red with petechiae, the coating is yellow and greasy, and the pulse is stringent. The treatment should be to dredge the liver and Qi, clear heat and cool the blood, and the formula can refer to Chai Hu Dredging Liver San and Gentian Diarrhea Liver Tang with addition and reduction. 4. Yin deficiency and fire type: In this category of patients, the fire is not from real fire, but from deficiency fire caused by yin deficiency and yang hyperactivity, so the essence of this category of patients is yin deficiency, and the fire is only superficial. For this type of deficiency fire, the use of bitter-cold agents alone can damage the transport and transformation functions of the spleen and stomach, resulting in ulcers that are prolonged, recurrent and unhealed. This type of ulcer is characterized by recurrent attacks, mild burning pain, accompanied by a dry mouth and throat, thirst and desire to drink, dizziness and tinnitus, palpitations and forgetfulness, insomnia and dreaminess, heat in the heart of the hands and feet, soreness and weakness of the waist and knees, etc. The treatment is to nourish Yin and lower the fire. The incidence of this type of oral ulcer is high. In clinical practice, according to the physical characteristics of the patient, if the patient has a poor physical condition, the Wei-Yang is not consolidated and shows symptoms of Qi deficiency, Si Jun Zi Tang can be used with the symptoms; if the symptoms of Yin deficiency are obvious, Gan Lu Drink (Sheng Shu Di, Mai Tian Dong, Scutellaria Baicalensis, Dendrobium, Loquat Leaf, Citrus Aurantium, Yin Chen, Gan Cao) can be used with the symptoms. In clinical practice, in addition to the above four common types, there are actually spleen deficiency and dampness trapped type and spleen-kidney yang deficiency type of mouth ulcers, usually mouth ulcers will appear at the same time with obvious signs, so combined with symptoms dialectical treatment, can fundamentally cure mouth ulcers.
