I'm no expert, but I looked into this issue for my mom some years ago (had cancer on her liver) and what you're looking for specifically is Silymarin, the ingredient in Milk Thistle that actually has the protective benefits. https://www.ncbi.nlm.nih.gov/pubmed/21466434 https://www.ncbi.nlm.nih.gov/pubmed/21466434 The issue with raw Milk Thistle supplements is that it's a lower dose of Silymarin as you're just getting the plant, you'd want "Milk Thistle Extract", which is concentrated Silymarin. As with all supplements though, read the label and research the brands you buy. Counterfeit products are rampant in the industry, as is inconsistent dosing. Mayoclinic has some dosing reccomendations: http://www.mayoclinic.org/drugs-supplements/milk-thistle/dosing/hrb-20059806 http://www.mayoclinic.org/drugs-supplements/milk-thistle/dos...
