Asthma is a disease affecting the respiratory tract with symptoms that include wheezing, shortness of breath and cough. The incidence of asthma is increasing. Genetic factors, environmental allergens and diet are all risk factors for developing asthma. Bromelain is a natural supplement that may help improve symptoms of asthma. However, if you suffer from this condition and consider taking bromelain, you should first talk to your doctor.
About Bromelain
Bromelain is an enzyme derived from pineapples and contains a combination of enzymes involved in digestion called proteolytic enzymes. It has been used in South America in folk medicine for various inflammatory conditions and digestive problems. In Europe, the German Commission E approved bromelain for treating inflammation following injuries and surgical procedures, notes the University of Maryland Medical Center. Due to its anti-inflammatory qualities, bromelain may also help asthmatic sufferers, but more research is needed to prove this benefit.
Research
According to a review of research studies that evaluated natural supplements for allergies and asthma, bromelain showed potential benefits in improving both conditions. However, there were no followup or larger trials to confirm these benefits. The review was published in the June 2002 issue of "Primary Care."
Memorial Sloan-Kettering Cancer Center notes research supporting the anti-inflammatory qualities of bromelain, explaining that bromelain decreases levels of prostaglandins and cytokines. These two markers of inflammation also cause swelling of the respiratory tract in asthma.
Forms and Dosage
Bromelain is available in capsule and tablet form. The dose recommended by the German Commission E for adults is between 80 and 320 mg of bromelain two or three times daily. However, for specific medical conditions, this dose may be adjusted by a health care provider.
Side Effect and Drug Interactions
Bromelain is generally considered a safe and well-tolerated supplement. In rare cases, it may cause digestive symptoms like diarrhea, vomiting or nausea. Bromelain may also cause allergic reactions in susceptible individuals. Children, pregnant women and individuals who suffer from high blood pressure, bleeding disorders or kidney or liver conditions should not use these supplements.
Considerations
Consult a qualified health care provider to learn more about bromelain and other natural supplements that may help you manage symptoms of asthma. Bromelain is not approved by U.S. Food and Drug Administration to manage asthma, so it should not be used to replace any conventional drugs prescribed by your doctor for this condition.
