I was researching ACV enemas recently, and all the protocols I saw called for 1 or 2 or 3 tablespoons of ACV in anywhere from 16--32 oz of water.
This would make only a slightly acidic solution (and it's as much for your liver as it is for your colon). There are also anecdotes about bleeding.
I never found out what would happen if you did an enema with a really high concentration of ACV, like 50% or higher. Who knows, could make you sick, could kill ya.
But in general there is a temptation - because candida is so frustrating - to just nuke the whole area and start from scratch.
That's a judgement call we all have to make.
But speaking of the colon, I really chimed in to recommend eating a big leafy salad every day, or at least 6 days a week.
For the first time in years I'm having normal BM's w/out taking massive quantities of probiotics.
I decided to try it after reading one of Remi96's posts. The ingredients I buy to make the salads cost just as much as the probiotics, if not more.
But there's no comparison. The salad is a meal, for one. And you get all the nutrients, vitamins, minerals, phyto-nutrients, fibers, etc, etc, etc.
I drink a little kefir here and there, and I still have some probiotics in the fridge that I keep forgetting to take,
but it's the salads that keep things normal.
