The research I ran across in medical textbooks talked about trypsin (pancreatic enzyme) with bile could result in destruction or weakening of the cyst forms. I have also read that pepsin will erode the protective cysts. There is also adequate research and practice in the use of enzymes such as Wobenzyme for the treatment of cancer. it is thought that the release of the enzymes will erode the outer coats of tumors, thus allowing the WBCs to attack the tumor.
