How effective are herbs in helping with flush?

I was looking at Julia Chang's website and was thinking of ordering some of the GCG and Coptis to prepare for one of my Liver Flushes in the future. However, I don't really have money to throw around (does anyone?!) and was wondering if it is really worth it to shell out the $$$ for the herbs.

Anyone have experience with her herbs? Would you recommend them?

Thanks!
