The present invention belongs to the field of medicine, and particularly relates to a traditional Chinese medicine composition for treating diseases caused by human papillomavirus, a preparation method and use thereof.
Human papillomavirus (HPV) is an epithelial virus that is a member of the genus A of the Papoviruidae family It is a small DNA virus that infects the epidermis and mucosal squamous epithelium. It is 52-55 nm in diameter and has no capsule. It has a regular icosahedral structure with 72 shells on the surface, and the viral genome is a double-stranded circular DNA molecule, which is widely distributed in humans and has a high degree of specificity. HPV has been found to have more than 100 subtypes. Low-risk HPV can cause a variety of benign lesions in the mucous membranes of the skin, such as condyloma acuminatum and skin warts. High-risk HPV is the primary cause of cervical carcinoma. Cervical carcinoma is one of the most common gynecologic malignancies in developing countries.
Condyloma acuminatum (known as “SAO warts” or “SAO verrucas” in Chinese medicine), common warts, etc., are all kind of benign skin tumors produced by human papillomavirus (HPV) through the skin's mucous membrane infection caused by the subtle damage of the human body through an incubation period of 3 to 5 months. Condyloma acuminatum, also known as spiky wet warts, genital warts, and sexually transmitted warts, can cause common infectious diseases characterized with verrucous vegetations at the places of genitalia, anus etc., which occurs mostly around the genitals and anus of men and women. Generally, it is a papule with a needle tip size at the beginning, which is light red, dark red or dirty gray, and then develops into a papillary ridge, which merges or overlaps each other, like cauliflower, moist and soft, and often accompanied by varying degrees of itching.
In recent years, the high incidence of cervical carcinoma is seriously threatening the health and life of women. Only by effectively removing HPV can we effectively prevent the occurrence of cervical carcinoma. Modern medicine for the prevention of cervical HPV infection is vaccination, but the scope is limited, expensive, and need repeated injections. There is currently no effective means of infecting HPV. Injection of interferon is difficult to promote, since it has toxic and side effects, and with long course of treatment and low cure rate.
With the deepening of clinical research, some drugs for treating the above-mentioned diseases caused by human papillomavirus have appeared in the market Some of the existing drugs belong to the palliative, some use expensive components, and some are discontinued due to inaccurate efficacy during the application process.
Skin tinea is a contagious skin disease. The skin has red rash or small red plaque. The more scratches, the skin will be more red itchy. The symptoms of skin tinea can be single, or several pieces, and merge with each other. The affected area often appears in places with more sweating, such as the feet, the inner thighs, etc., can also occur in the trunk and limbs, occurs less on the face, and the performance is often atypical, long-term skin lesions can be dark red, with thin scales on it, and local hyperpigmentation. Dermatophytosis is a common and frequently-occurring disease, second to dermatitis and eczema, and in the first place in infectious skin diseases.
