Soda water can wash vulva, but it can only be washed if there are indications, because soda water itself is an alkaline solution, and the purpose of washing vulva is to change the local pH value, which is often used for candida infection. Candida likes to grow in acidic environment. If washed with alkaline soda water, the local pH value will change, thus inhibiting the growth of candida and alleviating clinical symptoms. However, cleaning vulva with soda water can not completely treat candidal vaginitis, and corresponding drugs should be used for treatment. For example, baking soda water can be used to wash vagina after 7 days of continuous medication, but baking soda water can only be used to wash vagina under the guidance of a doctor, and regular medical baking soda should be selected.

Baking soda water itself has no obvious anti-inflammatory and bactericidal effects. The main function of baking soda water is to change the pH in vagina, and it is often used for candida infection. Because candida likes to grow in acidic environment, and baking soda is an alkaline solution, washing with baking soda will change the pH of vagina, thus inhibiting the growth of candida and relieving symptoms. However, it should be noted that when using baking soda water to rinse vagina, the concentration of baking soda water should be strictly controlled, so as not to burn the vaginal mucosa if the concentration is too high. If it is not a vaginal inflammatory disease caused by Candida albicans infection or has no symptoms, baking soda is not recommended to clean the vagina. Because women's vagina is an acidic environment, this acidic environment is more conducive to maintaining the balance of women's vaginal flora, enhancing women's vaginal resistance, and not prone to inflammation. If it is often cleaned with baking soda, the acidic environment of vagina will be reduced, the normal flora of vagina will be changed, and the internal environment of vagina will be destroyed, leading to inflammation such as flora imbalance.
