You're saying these things will dissolve big liver stones and then you will safely pass them?
Yes. In fact ox bile is a mainstream method of dissolving gallstones.
Are all these, except bitters, OK without a gal bladder?
You are not really going to flush them. But they can be dissolved with things such as ox bile, bitters, lecithin granules and chanca piedra (Phyllanthus niruri).
Without a gallbladder it would be best to stick to the lecithin granules, which are great for the liver anyway. Chanca piedra is also good as long as it is used in capsules so it does not act as a bitter. Chanca piedra is also a great liver support herb.
