Acetic acid in a vaginal context typically refers to a diluted solution utilized for douching or rinsing in the vaginal area. The primary purpose of such solutions is to help maintain the natural acidic pH balance within the vagina, which normally ranges between 3.8 to 4.5. This acidic environment serves to inhibit the growth of harmful bacteria and yeast.

The common formulation involves diluting acetic acid in water, often using vinegar as a source due to its acetic acid content. However, it is important to note that the practice of douching, including the use of acetic acid solutions, has become less recommended by healthcare professionals in recent years.
