I didn't get to go all natural before they took my gall bladder out! I should've checked into it though, but, I was really bad physically so just had it done.
I use Standard Process for a variety of things and I would suggest to go with it if they make something for the gall bladder flush.
I take their Wormwood and several other things..because I have blocked bile ducts.I am sure I needed my gall bladder out and had stones (which is bile) because of blocked ducts in and around pancreas, gallbladder and liver. I take a liver & pancreas cleanse too which really helps (Biotics Research). It takes a lot of time for all of this, I do feel better when I take all of this though. Make sure you get tested to see if there are other things you need along with the gall bladder cleanse.
