liver formula/herbs

Hi,

I have been considering taking some liver supporting herbs as I believe I may have something going on with my liver. Can your liver/gallbladder formula be taken long term to support liver health, or is it mainly intended for a once in a while "tune-up"?

Additionally, what is your take on Artichoke and Dandelion, as they seem to be recommended a lot on the liver forums, but I noticed they are not in your liver formula?

Thanks
