Serrapeptase is a natural enzyme extracted from the intestines of silkworms. Dr. Napier, a German physician, in 1975 conducted extensive research in using Serrapeptase for the relief of pain and swelling. He also noticed that this enzyme was very effective in destroying blood clots and arterial plaque without any adverse reactions. His patients thus avoided heart attacks and strokes. In nature, this enzyme bores a whole in the silkworm’s cocoon to release the moth. Physicians in the United States are becoming more interested in the attributes of this enzyme.
