It is not recommended to use salt water for vaginal inflammation. Salt water washing cannot kill the bacteria and can only improve the symptoms of vulvar itching for a short time. If you are diagnosed with vaginitis, you need to use the corresponding medication according to your condition under the guidance of your doctor. The common medications used to treat vaginitis are vaginal plugs and topical lotions. The topical lotion is usually a proprietary Chinese medicine, which has a clearer effect on heat and itching and inhibits the growth of bacteria.
