Boswellia extract has been in use for centuries as an ingredient in asian herbal treatments. It contains boswellic acid which is thought to strengthen connective tissue and improve the blood supply to joints. Studies have shown that boswellia is often a better remedy than a prescription medication for conditions such as arthritis where it can reduce the inflammation and pain. It also has a mild sedative effect, which will help the body to cope better with pain. Boswellia is of benefit in digestive disorders such as crohns disease. Other digestive disorders that may be eased with this herb include diarrhea and ulcers. When the extract is taken internally, it is thought to be especially beneficial for back pain, while boswellia extract in creams can be massaged into affected areas to reduce stiffness.
