| Bromelain |
|
Bromelain is a mixture of enzymes found naturally in the juice and
stems of pineapples. Called a proteolytic enzyme, bromelain is
believed to help with the digestion of protein. Some bromelain appears to be absorbed by the body intact, so it's also thought to have effects outside the digestive tract. In fact, bromelain is often marketed as a natural anti-inflammatory for conditions such as arthritis. It's one of the most popular supplements in Germany, where it is approved by the Commission E for the treatment of inflammation and swelling of the nose and sinuses due to surgery or injury. Bromelain is typically extracted from pineapples and made into capsule or tablet form. Because it's able to digest protein, bromelain is available in some grocery stores as a meat tenderizer. A topical form of bromelain is also being explored experimentally for burns. When used for as a digestive aid, bromelain is usually taken with meals. When used for inflammatory conditions, practitioners typically recommend taking bromelain between meals on an empty stomach to maximize absorption. |
| Why Do People Use Bromelain |
|
Surgery and Injuries There is some evidence that bromelain supplements may reduce swelling, bruising, inflammation and pain after surgery and injury. In Germany, bromelain has been approved for these uses by the Commission E since 1993. Large, well-designed studies are needed, because not all studies have confirmed these results. Sinusitis Bromelain has been suggested as a complementary treatment for sinusitis. Preliminary studies suggest that it may help reduce congestion, improve breathing and suppress coughing. It's approved by the Commission E as a complementary treatment for nasal and sinus swelling and inflammation after ear, nose and throat surgery. A review of three small but well-designed previously published studies found that bromelain may help relieve sinusitis symptoms. Digestion Bromelain is a popular natural digestive aid due to it's ability to digest proteins. It's used for bloating, gas and other digestive symptoms and for conditions such as irritable bowel syndrome. Bromelain is often used alone or in combination with other enzymes such as lipase, which digests fats, and amylase, which digests starch. There is little research, however, on the safety or effectiveness of bromelain for digestion. Osteoarthritis Bromelain may help with mild pain associated with osteoarthritis. It's a common ingredient in nutritional supplements marketed as a natural pain remedy for arthritis. Large, well-designed studies are needed to see if it is effective and to find out about possible side effects. Cancer Bromelain and other proteolytic enzymes have been explored as a complementary treatment for cancer. Although there is some preliminary research, there isn't enough evidence at this time on the safety or effectiveness of bromelain for cancer. It should never be used in place of conventional treatment. |
| Side Effects and Safety Concerns |
|
Some of the more common side effects of bromelain include indigestion, nausea and diarrhea. Other side effects may include vomiting, increased heart rate, drowsiness and abnormal uterine bleeding or heavy menstruation. Bromelain has resulted in allergic reactions and asthma symptoms, including breathing problems, tightness in the throat, skin hives, rash or itchy skin. People with allergies to pineapples should avoid bromelain. Allergic reactions may also occur in people with allergies to latex, carrot, celery, fennel, rye, wheat, papain, bee venom or grass, birch or cypress pollens. People with peptic ulcers should not use bromelain. People with other digestive disorders should consult a qualified healthcare professional before using bromelain. Theoretically, bromelain may increase the risk of bleeding, so people with bleeding disorders and those taking medication that can increase the risk of bleeding should only use bromelain under the supervision of their physician. It should not be taken two weeks before or after dental procedures or surgery. |
