Fuggles,

Chancra Piedra = stone softening, should be used a few weeks ahead of the flush as a prep.

Fresh grapefruit or fresh lemon juice, mixed with the needed oil, stimulates the liver to produce huge amounts of bile, the fresh juice helps to move the oil out of the stomach quickly.

If you do not use Epsom Salts , how do you plan to flush out the bowel, and achieve the necessary dilative effect? The ES really opens up the bile ducts, and is very helpful if you have large stones.
