Intra-hepatic stones rarely show up on an ultra sound. If you didn't show Gallstones after doing clenses then you know you have had some success. Incredible that dandelion should make you feel sick. . . .unless it was helping clear more stones from your liver and that was making you sick. Cleansing the liver and dumping stones, chaff and stale bile on your intestines can make you incredibly sick. It then becomes necessary to cleanse the entire intestinal tract with things like Epsom Salts and Coloson, psyllium,charcoal and general laxative actions. In other words getting your liver cleaner can make you sicker so follow through. Keep at it, you may be getting somewhere. I would recommend milk thistle, and buplurum, but there is so much I can't possibly know. Keep researching, keep at it. Ther are so many helpful herbs out there. A liver can take like three years to heal.
