Bromelain is the name of a group of powerful protein-digesting, or proteolytic, enzymes that are found in the pineapple plant (Ananas comosus). Discovered in 1957, and widely studied since then, bromelain is particularly useful for reducing muscle and tissue inflammation and as a digestive aid. Supplements are made from enzymes found in the pineapple stem.
Boswellia, also known as boswellin or “Indian frankincense,” comes from the Boswellia serrata tree that grows in the dry hills of India. For centuries, traditional Indian healers have taken advantage of the anti-inflammatory properties of the tree bark’s gummy resin, called salai guggal. Modern preparations made from a purified extract of this resin and packaged in pill or cream form are used to reduce inflammation associated with osteoarthritis and rheumatoid arthritis. Unlike conventional NSAIDs (nonsteroidal anti-inflammatory drugs) such as ibuprofen–the accepted treatments for joint inflammation–boswellia doesn’t seem to cause stomach irritation. It also may be effective for back pain and certain chronic intestinal disorders.
