Abstract

The invention relates to a banga extract and the application in preparing antiviral medicine, which can not only inhibit various etiological agent bacteria, but also can play evident antiviral function through a plurality of connections such as inhibiting virus absorption, directly killing living virus, and inhibiting proliferation of virus, thereby the extract can be applied in preparing medicine which resists bacteria and virus, and simultaneously can be applied in food, health products and cosmetics. The banga extract of the invention can be made into medicine compound in preparing of the medicine which resists bacteria and virus in single-flavor or compound style, in particular to the application of the single-flavor or the compound style in preparing medicine compound for curing genital herpes. Simultaneously, the extract can be used incorporated in food, health products and cosmetics. The banga extract has the advantages of rich raw material, low cost, simple extraction technique, and can be conveniently shaped into various shapes, and has important developing and applying prospect.

Description

technical field [0001] The invention relates to the extract of Tibetan medicine Bangga and the application of the extract in the preparation of antibacterial and antiviral drugs, belonging to the field of ethnopharmacy. Background technique [0002] The increasing bacterial resistance caused by the extensive use of antibiotics has become one of the problems of common concern all over the world. Especially the drug resistance rate of Staphylococcus aureus has reached more than 90%. Herpes simplex virus type II mainly causes skin and mucous membrane infection in the genital area. The virus enters the body through the respiratory tract, oral cavity, genital mucosa and damaged skin, and resides in the normal mucosa, blood, saliva and sensory ganglion cells of the human body. When the body's resistance declines, such as fever, gastrointestinal dysfunction, menstruation, pregnancy, focal infection, and emotional changes, the latent HSV-II in the body is activated to cause diseas...
