i would also check out dr. richard shultz. i believe there's a forum for him at this website. he has a five day liver/gallbladder flush and detox. he also has an incurables program. he is a master herbalist. i tried his liver/gallbladder drink when i thought i still had some stones left over from a clark flush. the stones came out and it was a much milder flush -- was easier to handle.
