Bromelain is a protein digesting enzyme that works as a natural anti-inflammatory for your body. It is extracted from the stem and fruit of a pineapple plant and works by breaking down the proteins in your swollen tissues of your body. Used for many years, this natural alternative to medication can effectively relieve the symptoms most commonly associated with arthritis, gout, carpal tunnel syndrome and PMS. Often used to treat sports injuries the benefits of bromelain are extensive when it comes to treating any conditions marked by the symptoms of inflammation especially in the case of tendonitis, sprained ankles and ligaments as well as inflammation of the knees. Thought to be much safer than prescription medication the amount that you need to take varies depending on the condition and the severity. Although it can be found by itself it is usually found along with other anti-inflammatory compounds to make it more comprehensive and effective. There are some side effects but they usually are short and after about a week or so disappear completely. But you may have some diarrhea and nausea when you first start to take bromelain. Also, if you are allergic to pineapple then you may have some allergic reactions to anything containing bromelain. Recent studies have concluded that patients with rheumatoid arthritis find bromelain to be extremely beneficial in relieving the pain and swelling associated with it. The same can be said for osteoarthritis and gout which also have symptoms of pain, redness and swelling. Pure bromelain is recommended for serious conditions and diseases but using a compound in the case of sports injuries or arthritis may prove to be better for you because it is more all inclusive to deal with all symptoms.
