The causes of oral ulcer are: (1) long-term mental stimulation, anxiety, anger, radiotherapy, chemotherapy, physical therapy, blood washing, staying up late, fatigue, sedentary computer (due to inactivity and mental stress) and so on. (2) Smoking, drinking, drinking drinks, eating peppers, old pickles, tofu, stinky tofu and other irritating foods are frequent. (3) Long-term cold, heat and water shortage. (4) Eat cold, hard, barbecue, fried and other foods. (5) Eat fresh-picked wheat, corn, sweet potato and other food crops. (6) It is related to the digestive system, such as dyspepsia, gastritis and constipation. (7) A small number of people are also related to genetic factors. (8) In addition, it is related to endocrine disorders. Some people get oral ulcers before menstruation. Due to one or more of the above factors, it leads to excessive internal heat, or endocrine disorder, which in turn leads to autonomic nerve disorder, microcirculation channel rupture, and makes one or more trace elements (VB2, VB6, B 12, VC, etc. ) are defective, leading to the primary virus entering through the gap, and then infected with recurrent ulcers. In particular, the oral cavity is the most prone to ulcers, followed by anus, stomach and female vagina. Why are these parts prone to ulcers? That's because these parts can secrete high-precision and high-quality liquid to meet the needs of a certain part of the body and adjust the balance of the body. Therefore, these parts need more trace elements, and once the supply channels of trace elements have problems, these parts are not perfect and are prone to ulcers. These parts are like the fuse of a switch. Once overloaded, they will automatically rupture (ulcer). The purpose of ulcer is: first, to prevent the loss of trace elements in these parts, and second, to protect themselves and avoid the occurrence of major diseases. If there are problems in some parts due to one or more reasons, ulcers will gradually appear. Generally, it takes about a week from appearance to peak. If trace elements are satisfied, it will take a week at the earliest to heal itself. Otherwise, it will not heal for a long time.

Recurrent aphtha is one of the diseases with the highest incidence in oral mucosa, which is the easiest to recover and more troublesome to treat. To treat oral ulcers, drugs should be used first; Secondly, we should pay attention to daily life, exercise more, keep a positive and optimistic mood, and overcome the bad habits related to oral ulcers, which is of great benefit to the rehabilitation of ulcers.

Long-term countermeasures: try to eliminate or limit the interference and destruction of the above factors on the body, always create a benign microcirculation environment for your body, and fundamentally eliminate the conditions for ulcer breeding. At present, this is also the basic method to eradicate oral ulcers.

Short-term emergency measures: 1, taking Sanhuang tablets orally. 2. Apply some oral ulcer powder, ice boron powder, or Liushen Pill on the ulcer surface, or apply Yunnan Baiyao externally on the ulcer surface. 3, supplement trace elements (vitamin supplementation is difficult to take effect in a short time, it takes 3 to 4 months to achieve the effect, so vitamins should be pressed into noodles before going to bed and directly applied to the ulcer surface, so the effect comes faster) 4, drink more porridge, drink more water, eat more vegetables and fruits, and help repair the microcirculation channel. 5. The application of "Jiangkuiyangling" is the best way to treat oral ulcer. Generally, patients can just apply it once. Medication method: first wipe off the ulcer surface with sterile cotton swab, and then apply Kouchuangling. It doesn't hurt or itch. Severe cases can be cured after three or five times without side effects.

There is no way to eradicate it with drugs, because oral ulcers are the same as colds, diarrhea, fever, headaches and other diseases. When people encounter bad weather changes, their bodies have to deal with it. At this time, their body resistance is the worst, and cold bacteria will take advantage of it, so a cold will happen. When your stomach catches cold, or you eat cold drinks, if your intestines can't resist the invasion of cold, you should use diarrhea to protect your body. Fever is also a sense of self-protection to kill bacteria. Ulcer is a dangerous signal from the body, so we must pay close attention to it. Therefore, when a person's body meets certain conditions or environment, it will produce certain diseases. Only by avoiding the conditions or bad environment can people avoid the occurrence of this disease. The so-called eradication can only be talked about by avoiding the conditions under which it arises. Some people's oral ulcers are difficult to eradicate because of genetic factors. Others are related to occupation. If we can't avoid that environment, it is impossible to relieve the attack of oral ulcer.

At present, there are no effective methods in regular hospitals. Although there are many treatments for oral ulcer, they are basically symptomatic treatment. The main purpose is to relieve pain or reduce the number of recurrences, but the recurrence cannot be completely controlled. It will take at least a week, more than a month or even longer. It is difficult to get rid of the chronic disease of oral ulcer without removing the breeding conditions of oral ulcer, so it is more important to prevent the recurrence of this disease.
