Overview
Bromelain is combination of proteolytic enzymes (protein digesting enzymes) found in the stems and juice of the pineapple. Bromelain has been in use as a therapeutic supplement since 1957 and is one of the most widely used herbal medicines in Europe.

Effects on Digestion
Though there is little research currently available on bromelain effects on digestion it is often recommended as a digestive aid. This is because it has the ability to break down proteins and also has anti-inflammatory effects, which may enable it to alleviate symptoms including flatulence and bloating and also to prevent heartburn. It is also recommended for easing the symptoms of irritable bowel syndrome. As a digestive aid it is often combined with starch digesting enzymes such as amylase or fat digesting enzymes such as lipase.

Effects on Inflammation
Bromelain has anti-inflammatory effects that have been shown, in studies at the University of Connecticut, to be due to its effects on the immune system's cells, specifically, types of lymphocytes known as CD4+T cells. This makes bromelain useful for the treatment for a number of disorders that cause inflammation including rheumatoid arthritis, irritable bowel syndrome, allergies of the airways and sprains and muscle injuries.
-
Topical Effects
Bromelain is an ingredient of some topical ointments in which it is most commonly used for the treatment of sprains, strains and bruising because of its ability to reduce inflammation. It is also recommended for minor burns as it may be useful for removing the dead skin cells caused in third- and second-degree burns. It may also help to reduce the soreness and swelling caused by stings and insect bites.

When to Take Bromelain
The suggested dose for general conditions is 80 to 320 mg, twice daily, with meals. For digestive disorders the suggested dose is 500 mg per day divided and taken with each meal. For arthritis the suggested dose is 500 to 2000 mg each day in 2 equal doses. Bromelain should not be used in children since the effects are not known. It is not recommended that you take bromelain for a longer period than 8 to 10 days.

Possible Side Effects
Reported side effects from bromelain include nausea, diarrhea, vomiting and amenorrhea (prolonged menstrual bleeding). If you experience any of these symptoms, you should stop taking bromelain immediately and seek medical advice. Bromelain should not be taken if you are using tetracyclines or blood thinners.
