A douche is a device used to introduce a stream of water into the body for medical or hygienic reasons, or the stream of water itself. Douche usually refers to vaginal irrigation, the rinsing of the vagina, but it can also refer to the rinsing of any body cavity. A douche bag is a piece of equipment for douchinga bag for holding the fluid used in douching. To avoid transferring intestinal bacteria into the vagina, the same bag must not be used for an enema and a vaginal douche. The word douche came to English via French where today it means shower. It is thus a notorious false friend encountered by non-native speakers of English. Vaginal douches may consist of water, water mixed with vinegar, or even antiseptic chemicals. Douching has been touted as having a number of supposed but unproven benefits.
