We do know that from time to time people do expel a hard pigment or calcified stone which are from the gallbladder and they are sizeable.
We know that research centres are using Soya-oils and citric esters to investigate the biliary system.
We know that Chinese doctors in hospitals use a combination of drugs and oil to expel Gallstones up to 2 cm.
