Bromelain

Bromelain (proteolytic enzyme) extracts can be obtained from both the core fruit and the stems of pineapple. Potentially important chemical differences appear to exist between extracts obtained from the stem versus the core fruit. Further studies have shown that bromelain found in pineapples has a wide variety of health benefits of pineapple. However, they stressed out many of these benefits may not be related to the different proteinase enzymes found in the crude extract. However, most of the pharmacological effects are attributed to bromelain such as antiinflammatory action, smooth muscle relaxation, stimulation of muscle contractions, ulcer prevention, appetite inhibition, enhanced fat excretion, sinusitis relief.
