Acetic acid, which at low concentrations is known as vinegar, is an acid used to treat a number of conditions.
As an eardrop it is used to treat infections of the ear canal. [1] It may be used with an ear wick. [2] As a liquid it is used to flush the bladder in those who have a urinary catheter in an attempt to prevent infection or blockage. [3] As a gel it may be used to adjust the pH of the vagina.
