Is there a drug-free treatment for vaginal dryness?
There are many causes of vaginal dryness. It may be caused by reduced estrogen levels, infection, medications, and other things. Before treating yourself, talk to your health care provider.

Water-based lubricants work very well. Lubricants will moisten the vaginal lining for several hours, and the effect of a vaginal cream can last for up to a day.
Soybeans contain plant-based substances called isoflavones that weakly mimic the action of estrogen. A diet rich in soy foods would therefore be expected to improve symptoms of vaginal dryness. Research studies on isoflavones are ongoing, but so far the ideal sources or dose is still unknown. Soy foods include tofu, soy milk, and whole soybeans (also called edamame).
Many women claim that creams containing wild yam relieve their symptoms of vaginal dryness. However, no well-designed research has evaluated these creams, and extracts of wild yam have not been found to have estrogen- or progesterone-like activities. Some of the products may have synthetic medroxyprogesterone acetate (MPA) added. MPA is a derivative of progesterone, and is also used in oral contraceptives. Like all supplements, MPA-containing products should be used with caution.
Black cohosh is an herb sold as a dietary supplement for the relief of menopausal symptoms. There is no clear evidence that this herb relieves vaginal dryness.
