Bowellia serrata, commonly known as boswellia or Indian frankinscence, is a powerful anti-inflammatory herb used widely for the treatment of joint pain, arthritis, ulcerative colitis and other digestive tract disorders. It has the added benefit of being a powerful antioxidant. It acts in the same way as non steroidal anti-inflammatories (eg nurofen) by inhibiting leukotrienes which are pro-inflammatory mediators. The great thing about boswellia is that it has none of the nasty side effects which are commonly associated with NSAIDS such as nausea. vomitting, heartburn, diarrhoea, headache and damage to the lining of the digestive tract.
