Pepper water cannot treat gynecological inflammation, but can be used as an adjunctive treatment for gynecological inflammation if the doctor evaluates it as applicable to the patient’s current condition. In Chinese medical theory, pepper water has the effect of dispelling wind and relieving itching. If the itching is caused by vaginitis, you can use pepper water to fumigate the pubic area during treatment to relieve the discomfort caused by itching, and modern theoretical studies have also found that pepper boiled in water has a certain inhibitory effect on vaginitis caused by Trichomonas vaginalis. However, the treatment of vaginitis requires the use of anti-infective drugs for the infection in order to effectively control the condition. For example, trichomoniasis can be treated with metronidazole, and mycotic vaginitis can be treated with mycoplasma and other drugs. In addition, if pepper water is used improperly for a long time, it can easily irritate the mucous membrane of vulvar skin or cause burning sensation in vulva. Therefore, it is not recommended that patients with gynecological inflammation use pepper water to wash their vulva on their own. It is recommended to go to a regular hospital for examination and targeted treatment.
