Can anyone explain enemas to me?

I heard about it... is it comfortable? Will it hurt? How do i get one? If you use it, tell me all about.. please

there are folks that believe to be healthy you should keep
the colon cleaned out and lubed up -- consequently they
use various herbs and liquids to clean out the colon.
The "flush" is accomplished with either a rectal syringe,
or a fountain syringe . Insert in rectum and let go with the
liquid until it feels a little uncomfortable. Hold inside as
long as possible and don't waste time getting to the stool.
it can, but don't have to be uncomfortable........ personally,
don't know the value but think that it's possible that it could
have negative effects on the good bacteria in the colon if
done too often.
