Clinically, it is not recommended to wash the vagina with white vinegar in the absence of any symptoms. The vagina itself is self-cleaning and has its own pH and normal flora. If you wash the vagina with white vinegar, it will change the vagina into an acidic environment, which will favor the growth of pathogenic bacteria, so it is not recommended to use white vinegar to wash the vagina. If you have trichomonas infection, you can use white vinegar to prepare a solution to wash your vagina, but you should not use the original white vinegar solution to wash your vagina to avoid damage to the vaginal mucosa. For example, in clinical practice, if white vinegar is used to douche the vagina it can be prepared to douche the vagina at a rate of 1%, which will not affect the body accordingly.
