It is a kind of Chinese patent medicine, a health care drug, over-the-counter, with the main ingredients including Serpentine, Dulcimer and Mugwort. The actual itchiness of the vulva can be treated with the help of the Jieer Yin lotion, which is related to the specific cause and degree of the condition. If it is only simple vulvar itching, or vulvar eczema, contact dermatitis, ringworm and other skin diseases, and is not accompanied by abnormal leucorrhea, you can use the cleansing lotion to relieve the symptoms. If, in addition to vulvar itching, the vulva is red and swollen, and the discharge is increased and is white and sticky, watery, or grayish yellow or yellowish green and thin and purulent, and there is an odor, then it may be vaginitis caused by mold, trichomonas, etc. If the condition is mild, the use of cleansing lotion can help relieve vulvar itching to a certain extent, but it is still necessary to actively consult a doctor and follow the doctor’s instructions for treatment with antibacterial drugs, such as Metronidazole, Tinidazole, etc. If the vulva itching is heavy or caused by other diseases, such as herpes, condyloma acuminata, cervicitis, vulvar tumor, diabetes, uremia, etc., the use of cleansing lotion in such cases will not play a therapeutic role. It is advisable for patients to seek medical attention and improve the relevant examination to clarify the cause of the disease and actively carry out treatment to avoid aggravation. In addition, even though it is an over-the-counter drug, it is still recommended to use it under the guidance of a professional doctor and to use it on time, in the right amount and according to the course of treatment, and to avoid using it privately to avoid aggravating the condition. It is important to note that women who are allergic to the drug, as well as those who are menstruating or pregnant, should avoid using it. If there are any adverse reactions such as local skin tingling, increased flushing or vulvar itching that is not relieved during use, the drug should be discontinued in time and medical treatment should be actively sought.
