Sodium bicarbonate used in medical practice is the same as edible sodium bicarbonate, which can be used to cleanse the vulva. The concentration of the drug should be taken into account when washing, for example, a clinical concentration of 5% is required to wash the vulva. If the concentration is too strong, the alkaline solution may cause damage to the skin of the vulva or the vaginal mucosa, and special attention should be paid to this. In daily life, if there is no discomfort, it is not recommended to use sodium bicarbonate to cleanse the vulva because the vagina has its own self-cleaning function and its own normal flora, and if sodium bicarbonate is used, it changes the pH of the vagina and may cause adverse effects. If you have Candida vaginitis, you can use sodium bicarbonate to cleanse the vulva and vagina to change the local pH and inhibit the growth of Candida.
