Serrapeptase is a Non animal Proteolytic enzyme, it is a common natural treatment for inflammatory and traumatic swellings.

Serrapeptase and Sinusitis
Due to its anti-inflammatory properties, serrapeptase has been shown in clinical studies to benefit chronic sinusitis sufferers. In this condition, the mucus in patients’ nasal cavities is thickened and hypersecreted. This thickening causes mucus to be expelled less frequently. Japanese researchers evaluated the effects of serratiopeptidase (30 mg/day orally for four weeks) on the elasticity and viscosity of the nasal mucus in adult patients with chronic sinusitis. Serratiopeptidase reduced the viscosity of the mucus, improving the elimination of bronchopulmonary secretions

Cardiovascular Implications
Hans A. Nieper, M.D., an internist from Hannover, Germany, studied the effects of serrapeptase on plaque accumulations in the arteries. The formation of plaque involves deposits of fatty substances, cholesterol, cellular waste products, calcium and fibrin (a clotting material in the blood) on the inner lining of the arteries. Excessive plaque results in partial or complete blockage of the bloods flow through an artery, resulting in arteriosclerosis, or hardening of the arteries, and an ensuing stroke or heart attack. Still, further studies are called for in this area as Niepers research indicated that the protein-dissolving action of serrapeptase will gradually break down atherosclerotic plaques
