If you have pigment stones, I don't know what you can do other than see a naturopath who can prescribe herbs; and then Brett, I don't know how quickly they work.
If your stones are made up of cholesterol, which most of them are, it's important to...
* stay away from dairy food and saturated fats
* take oats each day eg Oat Brits which contains cholestyramine enzyme that prevents production of LDL cholesterol (the bad one)
* take Vit B3 as a companion to oats because cholestyramine needs B3 to work properly
But to break down the cholesterol type stones you already might have, I'm not sure what you can do. I'll have to research that.
Do any older close relatives have cholesterol problems?
