If you are just doing a maintenance detox, a coffee enema
or a water enema
with a teaspoon of Epsom Salts
should help you. To treat various things, there are various things you can add to the water. You can do a search in the search engine in the upper right hand corner for more information.
I'm not sure how people use ozonated olive oil in enemas as I've never done one. Again, you can use the search engine on that because I just don't recall the specifics of that ever being discussed.
Cucumber juice sounds fine, although it might make continuing on a water only fast a bit hard as it might trigger your hunger.
