If there are no clinical symptoms, such as increased vaginal discharge, vulvar itching, or odorous discharge, it is fine to rinse the vulva with water every day when taking a shower, and there is no need to wash the vulva with salt water. In case of clinical symptoms, it is also recommended not to blindly douche the vulva with salt water. It is better to know which pathogenic bacteria are infecting the vaginal secretions through laboratory tests and then give targeted medication. If you douche blindly with saline, it is likely to delay the disease, because abnormal vaginal discharge is often caused by different pathogenic infections, so it is recommended to pay attention to it and go to the hospital for examination before using medication for more scientific and rational treatment of the disease.
