The parasite cleanse will help by getting those herbs in your body. Next time you flush, put a dropper full in your oil and juice drink, its nasty tasting but might make your liver release what it has. You can also do an enema with the tincture. Do a warm saline enema first to clean out the bowel, then do 2-4 cups of water with a dropper of anti- parasite herbs and retain it for as long as you can while staying in the ever-so-dignified butt in the air position. That gets the solution deeper into the bowel.

I've heard that darker stones are more toxic. There is a good post on colors of stones in the FAQ.
