Boswellia serrata Roxb. ex Colebr. is a natural Indian remedy whose oleoresin is used as an antiarthritic and anti-inflam- matory. The major phytoconstituent is a volatile oil, a range of triterpenic acids named Boswellic acids which are thought to inhibit leukotrienes synthesis thus exerting pain-relieving properties that are useful in treating arthritis and joint pain.
