Frankincense (also known as olibanum) is an aromatic resin used in incense and perfumes, obtained from trees of the genus Boswellia in the family Burseraceae. There are several species of Boswellia that produce true frankincense.Resin from each is available in various grades, which depend on the time of harvesting.The trees start producing resin at about eight to 10 years old. Tapping is done two to three times a year with the final taps producing the best tears due to their higher aromatic terpene, sesquiterpene and diterpene content. Generally speaking, the more opaque resins are the best quality. Terpenes and bozoleic acids are the strongest compounds in frankincense that are anti-inflammatory.Frankincense also has antioxidant properties.Cheap resin is produced in the Horn of Africa, which is the Roman Catholic Church’s major source.
