Malic Acid 2400 mgs for 1 month!

I've taken 2400 mgs of malic acid for 1 month exactly. And I also took Chinese Bitters and Gold Coin Grass for 2 wks.

I did a flush last Saturday but I do not believe the 4 cm stone stuck in my bile duct was expelled. I could feel my gallbladder quivering but I didn't get out any emerald green stones like I did first time. All I got out was about 20 tan peasized stones...but where did these come from if not through my bile duct???

I took pictures but they didn't turn out well.

Does anyone have anymore advice as to what I can do to get that 4 cm stone out of my blocked bile duct???
