My friend has been suffering from oral ulcers this year. I don't know what's going on.

Eight treatment methods of oral ulcer aphtha, also known as oral ulcer disease, is a kind of recurrent oral mucosal ulcer damage, and its cause is not clear, which may be related to endocrine disorders, gastrointestinal dysfunction, intestinal parasites, viral infections, allergic reactions, local irritation and other factors. The patient's conscious burning pain can affect eating, talking and sleeping, and it is not easy to recover, often accompanied by symptoms such as bad breath and constipation. It can occur at any age, but most of them are young adults. At present, there is no specific treatment for this disease, but in clinic, the following prescriptions are more effective for readers to choose: First, gargle with strong tea. Compendium of Materia Medica, a pharmacopoeia of the Ming Dynasty in China, said: "Tea tastes bitter and cold, which can best reduce the fire ... when the fire falls, it will clear up." According to research, tea contains tannin, which has astringent effect, can promote the healing of oral ulcer surface, and can also diminish inflammation and sterilize, because tannin can make unicellular fungi. Tea is also rich in vitamin C (anti-scurvy) and vitamin B 12 (which can prevent and treat various inflammations). Others, such as vitamin P and vitamin K, have a certain effect on the repair of oral ulcer surface. Second, gentamicin therapy with sterile cotton swabs dipped in gentamicin 40000 IU 2m 1 injection on the surface of oral ulcer, and then applied for several minutes, four times a day. It is best to apply liquid medicine after three meals and gargling before going to bed, and it will generally heal in 2 ~ 3 days. If it is multiple oral ulcers or oral erosion, it can be diluted to 10ml with 40000 IU 2m 1 gentamicin and water for injection, and spit out after 3 minutes. Once every 6 hours, the effect is good. Third, vitamin E therapy Take a few vitamin E sugar-coated tablets and grind them into fine powder, and apply them to the ulcer surface four times a day, which will heal in 3 ~ 4 days. After that, you can take L ~ 2 tablets every night before going to bed and continue to take 1 month to prevent recurrence. Four. Vitamin B 12 and vitamin c therapy take one tablet of vitamin B 12 and one tablet of vitamin c, grind them into powder, mix them evenly, dip them in a little sterile cotton ball, apply them on the ulcer surface, and bite them for 5 ~ 10 minutes, so that the drugs can be absorbed directly (oral action is extremely slow), and generally they can be cured after 3 ~ 4 times. The mechanism is that vitamin B 12 can promote human metabolism. However, the concentration of vitamin B 12 in human body is very low, and it is rarely stored. Vitamin C can reduce the permeability of capillaries and reduce the edema of ulcer surface. The combination of the two drugs can play a local anti-inflammatory, bacteriostatic and analgesic role, accelerate the healing of ulcer surface, and make the ulcer difficult to recur. Dandelion decoction is bitter, sweet and cold when taken orally and gargled, and it can clear away heat and detoxify. Take fresh dandelion 100g (50g dry product), wash it, decoct it in water, drink the medicine, and rinse your mouth several times a day until it is cured. Six, Yunnan Baiyao therapy with sterile cotton swabs dipped in Yunnan Baiyao powder coated on the ulcer surface, the vast majority of people can recover after taking medicine for 3 days. Seven, Chinese patent medicine external application with tin powder, boron ice powder or Hou Feng powder sprayed on the ulcer surface. Eight, Salvia Miltiorrhiza According to reports, Salvia Miltiorrhiza 15g decoction (or Danshen tablets can also be used) can quickly cure oral ulcers, and its mechanism is that Salvia Miltiorrhiza has the functions of promoting blood circulation, removing blood stasis, improving microcirculation and inhibiting bacteria. The typical manifestations of recurrent oral ulcer are: at first, there are tiny spots of burning discomfort, and then gradually expand into superficial ulcers with a diameter of more than 2 ~ 3 mm The ulcer is slightly concave, and the surface is covered with a yellowish false membrane. The mucosa around the ulcer is red due to congestion, and the burning pain is obvious. When exposed to irritating food, the pain will be more serious. Recurrent oral ulcers are self-limiting and periodic. Recurrent oral ulcer can heal gradually in 7 ~ 10 days without special treatment, and the interval varies from a few days to several months.
