Enema proprie vocatur decoctio que per clistere mittitur.

A decoction that is inserted through a clyster-pipe is properly called enema.


Greek ἔνεμα /énema/ "injection, clyster" is derived from ἐνίημι /eníēmi/ "implant; send in; infuse", composed of ἐν- /en-/ {"in(to)"} + ἵημι /híēmi/ "release, let go; let flow". The word occurs in Dioscorides and Galen. It was adopted into Latin as enema by Theodorus Priscianus.

In the medieval period clyster meant the same as enema. It was a long metallic tube through which fluids were injected into the colon through the rectum. These fluids were most often lukewarm water but other decoctions were used. At the injecting end of the clyster there were small holes in the metal to allow medicinal fluid to escape and at the other end of the tube was a cup-shaped container into which the fluid was poured. Then with the help of a pumping action, a type of plunger, the fluid was introduced into the colon.
