It is better to wash bacterial vaginitis with potassium permanganate drops, as most of the occurrences of this disease are associated with an increase in the pH level of the vagina. The alkalinization of the vagina reduces the lactobacilli, which leads to the growth and multiplication of Gardnerella, anaerobic bacteria and other bacteria, so this is the time to increase the acidity of the vagina. Potassium permanganate is a strong oxidizing agent which is an acidic potion. When a woman has this vaginitis, it is best to take a sitz bath for 10-20 minutes every night to be able to improve the acidity of the vagina. It is better to give vaginal medication under the guidance of a doctor because washing alone is not very effective.
