Many people think that foaming at the corners of the mouth is "getting angry" and should be "getting rid of fire". Actually, this is herpes labialis. Herpes labialis is caused by the infection of herpes simplex virus, which is called "getting angry" in Chinese medicine. It mostly occurs in the mouth and mouth. It is caused by factors such as cold, fever, fatigue, lack of sleep, depression, nervousness and anxiety, which leads to the decline of immunity, the proliferation of herpes virus lurking in the body, and the foaming of the mouth.

There is a burning sensation at first, and then blisters, erosion and scabbing cluster later. The course of the disease is about one week, and it can recur. Needle-sized blisters often appear at the mucous membrane of the mouth and lips, often in a group, but also in two or three groups, and they feel a slight burning sensation, which can be "self-healing" or "recurrent" after a week or so. If herpes is caused by improper adjustment of immune mechanism or secondary infection after bursting, the course of disease will be prolonged. Treatment:

General antiviral drugs, such as ribavirin and Viral Spirit, can be used to treat herpes simplex, but acyclovir is the most effective. Because acyclovir has a special affinity for viruses, it is easily absorbed by herpes viruses and triggers a chemical reaction inside the virus, thus inhibiting virus replication. In the early stage of mouth blistering, applying acyclovir eye ointment twice a day can play a good auxiliary treatment effect. Because the eye ointment is administered locally, the side effects will be less than those of oral drugs.

Taking acyclovir tablets can have a radical effect. Usually take it four times during the day and once before going to bed at night, with 2 tablets each time. Because acyclovir will affect the liver and kidney, it is best to drink more water to avoid the influence of drugs on the kidney during taking the medicine, and people with liver and kidney dysfunction should use it with caution. 5% Acyclovir Ointment or 0. 1% Bumper Cleansing Cream is applied externally, and it is better to apply it alternately with dermatitis flat ointment. There are infected people plus chlortetracycline ointment. Wet application of ribavirin injection (ribavirin): Use a medical cotton ball or cotton swab and a small piece of gauze to wet apply ribavirin injection to the skin lesion, and apply 15min each time, 3-5 times a day. Traditional Chinese medicines for clearing away heat and detoxifying, such as Niuhuang Jiedu tablets and Xiaoyan Jiedu pills, are taken orally.
