The Ultraphos doesn't disolve stones it relaxes the Common Bile Duct. Once the Common bile duct is relaxed the liver can easily pass the stones and debris that are causing the congestion.
Ultraphos itself does NOT disolve gallbladder or liver "stones". They must be flushed.
The limits on the Ultraphos are to assure the vessels don't get too relaxed. You don't want structures falling completely apart. There needs to be some tone remaining in the musculature of the vessels. 90 drops per quart will do that. But I have done two quarts of AJ with the 90 drops in each quart in one day. I could tell too. The vessels in my arteries and veins were getting too relaxed. I could feel it when I bent over. Felt like my head was going to explode. So too much is not good. Only enough to relax the Common Bile Duct, not the rest of the vessels in the body.
And again, the Ultraphos does NOT disolve stones. The stones must be flushed out.
