Probiotics are good bacteria. Acidophilus, Bifidus and more... One brand is 'primal defense', I think. Also...23rdman was telling us how to make it on the bowel forum - with cabbage (!).
Milk Thistle is a herb that is excellent for repairing and nourishing the liver. It would be available at a good health store in tincture form. Or at a vitamin store with a bunch of other stuff for your liver in capsule. (I think tincture is much better than 'dead' capsules)
Milk Thistle and Dandelion work symbiotically together...so it's best to do both. You can drink dandelion tea, while taking milk thistle tincture.
I've gotta run now! (I'm late!)
please ask more questions if you need to...
*I hope you will flush...because that is what will REALLY get the sludge out!
