Bromelain a proteolytic protein-digesting enzyme derived from raw pineapple stems, breaks down a broad spectrum of proteins, has anti-cancer, anti-inflammatory and anti-fibrin properties; is an antibiotic and is effective over very wide pH range.
Bromelain is absorbed intact through the gastrointestinal tract, with the highest concentration of bromelain being found in the blood one hour after administration. However, its proteolytic activity is rapidly deactivated by food so make sure you take it on an empty stomach.
Bromelain has anti-platelet aggregating properties so it can lower HBP and help your blood to flow freely. Bromelain has been shown in clinical practice to be an excellent adjunctive treatment for upper respiratory problems such as chronic bronchitis and acute sinusitis.
