Clark's liver tea

Any thoughts on the liver support tea from Dr. Clark store? I was under the impression that alcohol extracts were more effective for the liver, although I guess that's a debatable theory. I have done 4 flushes and feel like I need to be doing some other liver support. I've used dandelion and milk thistle tinctures in the past without noticing much. It's not in the budget to take everything that would be useful, so I'm trying to find the best choice. Thanks!
