I consider it to be essential. As you know, serrapeptase is the digestive enzyme secreted by silk worms to dissolve thier cocoons. It is one of the most powerful enzymes for dissolving fibrin and in my opinion is a must for conditions where scars and fibrous tissue are involved. I rank it alongside chymotrypsin for use against cancer cells and tumors to strip away the outer protective layers so that the body's immune system and other cancer fighters can work best. Serrapeptase and bromelain are the two enzymes I use myself alongside the outstanding Garden of Life Omega-Zyme product.
