It is not a good idea to use products to clean your vagina. Regular vaginal douching changes the delicate chemical balance of the vagina and can make a woman more susceptible to infections. Douching can introduce new bacteria into the vagina which can spread up through the cervix, uterus, and fallopian tubes. Researchers have found that women who douche regularly experience more vaginal irritations and infections such as bacterial vaginosis, and an increased number of sexually transmitted diseases.
If you have an unusual vaginal odor you need to see your clinician for proper diagnosis since extreme odor may be sign of an infection or other serious problem, and using a douche may only complicate the condition.
Remember that it is ok to have an odor down there, but not an unusual one accompanied by irritation and unusual discharge.
