coffee enemas are pretty good for liver and constipation.
But if you want something that strikes the heart of the problem, a good digestive aid with ox bile, HCL and Pancreatin along with a good probiotic will take care of the constipation, to some degree. A good probiotic has tons of bifidos and lactobacillus, but raw milk kefir worked for me. Feels good to be crapping twice daily lol
Even further, yeah a Liver Flush its a very good idea. I need to find those damn mag sulfate salts in this city or order them online to do my first one.
