Not really worth doing a drinkable cleanse/flush as it will just rinse through these. 'Standard' colonic douches are much the same. These organless wonders seem to be quite crafty psychotropics and anchor themselves to your innards.. Those are only really useful as preparation for the real flushing, unfortunately.
Getting in touch with Volinsky et al. about their research and recommended treatments should point you in the right direction. Any dramas feel free to email/pm me if you need more information regarding the ascribed treatment - kits and solution ingredients are fairly low budget and will most likely need to be self/family-administered at home. Hope you enjoy enemas!
