The Egyptians cleansed body cavities in the mummification process with frankincense and natron. In Persian medicine, it is used for diabetes, gastritis and stomach ulcer. The oil is used in Abrahamic religions to cleanse a house or building of bad or evil energy—including used in exorcisms and to bless one's being (like the bakhoor commonly found in Persian Gulf cultures by spreading the fumes towards the body). The incense offering occupied a prominent position in the sacrificial legislation of the ancient Hebrews. The Book of Exodus (30:34–38) prescribes frankincense, blended with equal amounts of three aromatic spices, to be ground and burnt in the sacred altar before the Ark of the Covenant in the wilderness Tabernacle, where it was meant to be a holy offering—not to be enjoyed for its fragrance. Scholars have identified frankincense as what the Book of Jeremiah (6:20) relates was imported from Sheba during the 6th century BC Babylonian captivity. Frankincense is mentioned in the New Testament as one of the three gifts (with gold and myrrh) that the magi "from the East" presented to the Christ Child (). In traditional Chinese medicine, frankincense ( ) along with myrrh ( ) are considered to have anti-bacterial properties and blood-moving uses. It can be used topically or orally, also used in surgical and internal medicine of traditional Chinese medicine. It is used to relieve pain, remove blood stasis, promote blood circulation and treat deafness, stroke, locked jaw, and abnormalities in women's menstruation. Essential oil The essential oil of frankincense is produced by steam distillation of the tree resin. The oil's chemical components are 75% monoterpenes, sesquiterpenes, and ketones. Contrary to some commercial claims, steam distilled frankincense oils do not contain the insufficiently volatile boswellic acids (triterpenoids), although they may be present in solvent extractions. The chemistry of the essential oil is mainly monoterpenes and sesquiterpenes, such as alpha-pinene, Limonene, alpha-Thujene, and beta-Pinene with small amounts of diterpenoid components being the upper limit in terms of molecular weight. Essential oils can be diluted and applied to skin or the frangrance can be inhaled.
