Myth: Douching is healthy.
Douches are not necessary unless your doctor recommends them. In fact, douching can aggravate an existing infection and upset the delicate balance of the vagina, which is a self-cleaning organ, a lot like the eye or the mouth.
====== END QUOTE ========
Personally, douching never made much sense to me considering that human evolution would have figured out how to keep women folk's plumbing functioning fine w/o human intervention.
Well, just an FYI.
editted: forgot the ever important NOT in first line.
