Here is a link to Christopher Hobbs L.Ac.
I have his book Natural Liver Therapy but here is a link to the liver cleanse I have found to be easy and healthful:
http://www.healthy.net/scr/Article.asp?Id=845

Read the article, good info, and within it is a section for the LIVER CLEANSE skim down to the blackened highlighted section: Liver Cleanse

It takes a little organizing of the herbs for the tea, and using a cleansing diet at the same time, but it is an easy cleanse for any one who may be interested.

One word of caution: Be aware of grapefruit interaction with meds. I do not think the naltrexone has this problem as per Dr. Escapa's thread info.

Hope this is helpful for some of you, ART
