Boswellia serrata Resin Source & Identity
The botanical entity is Boswellia serrata Roxb. ex Colebr., a deciduous tree of the incense family, Burseraceae, growing in the dry hills of India. The part used is the resin, an aromatic oleo-gum-resin that exudes when the bark is cut and hardens into tears. Wood, bark and leaves are not part of this boswellia serrata extract.
Frankincense is traded from several trees. Boswellia sacra and B. carterii from Arabia and the Horn of Africa, B. frereana and B. papyrifera are different species with different resin chemistry. The Latin name is the only reliable way to separate Indian salai guggal from them.
Pentacyclic triterpenic acids called boswellic acids, a gum of polysaccharide nature and a volatile oil are the constituent families of the resin.
