Extracts of the Boswellia serrata sap, bark, and other plant parts have been taken by mouth for therapeutic purposes. People use Boswellia serrata for osteoarthritis. It is also used for many other purposes, including asthma, diabetes, and stroke, but there is no good scientific evidence to support these other uses.
 
Because boswellia is an effective anti-inflammatory, it can be an effective painkiller and may prevent the loss of cartilage. Some studies have found that it may even be useful in treating certain cancers, such as leukemia and breast cancer.
 
Due to the herb’s anti-inflammatory properties, boswellia may be effective in treating inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis (UC).
A 2001 study compared H15, a special boswellia extract, to the anti-inflammatory prescription drug mesalamine (Apriso, Asacol HD). It showed that the boswellia extract may be effective in treating Crohn’s disease.
Several studiesTrusted Source found the herb could be effective in treating UC as well. We’re just beginning to understand how the anti-inflammatory and immune-balancing effects of boswellia can improve the health of an inflamed bowel.
 
General dosing guidelines suggest taking 500 milligrams (mg) by mouth 1-3 times a day. The dosage may need to be higher for IBD.
The Arthritis Foundation suggests 300–400 mg three times per day of a product that contains 60 percent boswellic acids.
