Absolutely the Best Milk Thistle I've used!! I purchased two bottles some time ago but held off writing my review until I had a chance to give it a try. Both my wife and I suffer from Hepetitis C and we both take Milk Thistle daily.

Works great. Milk Thistle lowered my high and out of range hepatic liver lab test results.
