Boswellia is a genus of trees in the order Sapindales, known for their fragrant resin which has many pharmacological uses, particularly as anti-inflammatories. The Biblical incense frankincense was an extract from the resin of the tree Boswellia sacra, and is now produced also from B. frereana.[2]
Frankincense
There are four main species of Boswellia which produce true frankincense. B. sacra (synonyms B. carteri and B. bhaw-dajiana), B. frereana, B. papyrifera, and B. serrata,[2][3] and each type of resin is available in various grades. The grades depend on the time of harvesting, and the resin is hand sorted for quality.
Description
Boswellia are moderate-sized flowering plants, including both trees and shrubs, and are native to tropical regions of Africa and Asia. The distributions of the species are primarily associated with the tropics.[4] The greatest diversity of species presently is in Africa and India.[4]
The plants are dioecious.[5] The flowers may have 4-5 faintly connate but imbricate sepals with an equal number of distinct, imbricate petals.[5] Also, the stamens, that may contain nectar discs, have distinct glabrous filaments that come in 1-2 whorls and in numbers equaling or twice the number of petals; the tricolporate pollen is contained within 2 locules of the anthers that open longitudinally along slits.[5] The gynoecium contains 3-5 connate carpels, one style, and one stigma that is head-like to lobed.[5] Each locule of the superior ovary has 2 ovules with axile placentation that are anatropous to campylotropous.[5] The 1-5 pitted fruit is a drupe that opens at maturity.[5] The endosperm is usually lacking in the embryo.[5]
Medicinal uses
Boswellia has long been used in Ayurvedic medicine. Recently, the boswellic acids that are a component of the resin it produces have shown some promise as a treatment for asthma and various inflammatory conditions.[6] In West Africa, the bark of Boswellia dalzielii is used to treat fever, rheumatism and gastrointestinal problems.[7] Boswellia incense may even relieve depression.[8]
