Frankincense or olibanum (Arabic,Ù„Ø¨ÙŒØ§Ù† ,Lubban) is an aromatic resin obtained from trees of the genus Boswellia, particularly Boswellia sacra (syn. B. carteri, B. thurifera) (Burseraceae). It is used in incense as well as in perfumes.
Description: Obtained from the leafy forest tree Boswellia Thurifera, with leaves deciduous, alternate towards the tops of branches, unequally pinnated; leaflets in about ten pairs with an odd one opposite, oblong, obtuse, serrated, pubescent, sometimes alternate; petioles short. Flowers, white or pale rose on short pedicels in single axillary racemes shorter than the leaves. Calyx, small five-toothed, persistent; corolla with five obovate-oblong, very patent petals, acute at the base, inserted under the margin of the disk, acstivation slightly imbricative. Stamens, ten, inserted under the disk, alternately shorter; filaments subulate, persistent. Anthers, caducous, oblong. Torus a cupshaped disk, fleshy, larger than calyx, crenulated margin. Ovary, oblong, sessile. Style, one caducous, the length of the stamens; stigma capitate, three-lobed. Fruit capsular, three-angled three-celled, three-valved, septicidal, valves hard. Seeds, solitary in each cell surrounded by a broad membranaceous wing. Cotyledons intricately folded multifid.

Boswellia is a genus of trees known for their fragrant resin which has many pharmacological uses particularly as anti-inflammatories. The Biblical incense frankincense was probably an extract from the resin of the tree, Boswellia sacra.

There are four main species of Boswellia which produce true Frankincense 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. Anyone interested in frankincense would be well advised to first obtain a small sample of each type from a reputable dealer in order to ascertain the difference between each resin.

The trees on the Somali coast grow, without soil, out of polished marble rocks, to which they are attached by a thick oval mass of substances resembling a mixture of lime and mortar. The young trees furnish the most valuable gum, the older yielding merely a clear, glutinous fluid, resembling coral varnish.

To obtain the Frankincense, a deep, longitudinal incision is made in the trunk of the tree and below it a narrow strip of bark 5 inches in length is peeled off. When the milk-like juice which exudes has hardened by exposure to the air, the incision is deepened. In about three months the resin has attained the required degree of consistency, hardening into yellowish ‘tears.’ The large, clear globules are scraped off into baskets and the inferior quality that has run down the tree is collected separately. The season for gathering lasts from May till the middle of September, when the first shower of rain puts a close to the gathering for that year.

The coast of Southern Arabia is yearly visited by parties of Somalis, who pay the Arabs for the privilege of collecting Frankincense, and in the interior of the country, about the plain of Dhofar, during the southwest Monsoon, Frankincense and other gums are gathered by the Bedouins. (The incense of Dhofar is alluded to by the Portuguese poet, Camoens.)

Cultivation:

Frankincense is tapped from the very scraggly but hardy Boswellia tree through slashing the bark and allowing the exuded resins to bleed out and harden. These hardened resins are called tears. There are numerous species and varieties of frankincense trees, each producing a slightly different type of resin. Differences in soil and climate create even more diversity in the resin, even within the same species. These trees are also considered unusual for their ability to grow in environments so unforgiving that the trees sometimes grow directly out of solid stone, which the tree attaches to by means of a sucker-like appendage. The deep roots and its sucker like appendage prevent the tree from being torn away from the stone during the violent storms that frequent this region; the tears from these hardy survivors are considered superior due to their more fragrant aroma. The aroma from these tears are more valuable for their presumed healing abilities and are also said to have superior qualities for religious ritual. Tapping is done 2 to 3 times a year with the final taps producing the best tears due to their higher aromatic terpene, sesquiterpene and diterpene content. High quality resin can be visually discerned through its level of opacity. Omani frankincense is said to be the best in the world, although quality resin is also produced in Yemen, and along the north coast of Somalia. Recent studies have indicated that frankincense tree populations are declining due to over-exploitation. Heavily tapped trees have been found to produce seeds that germinate at only 16% while seeds of trees that had not been tapped germinate at more than 80%

Useful Parts : Frankincense is a resin — dried tree sap — that come from trees of the genus Boswellia (frankincense) and Commiphora (myrhh) common to Somalia.

History:
The name for this resin possibly comes from “incense of Franks” since it was reintroduced to Europe by Frankish Crusaders. Although it is better known as “frankincense” to westerners, the resin is also known as olibanum, which is derived from the Arabic al-lubÃ¡n (roughly translated: “that which results from milking”), a reference to the milky sap tapped from the Boswellia tree. Some have also postulated that the name comes from the Arabic term for “Oil of Lebanon” since Lebanon was the place where the resin was sold and traded with Europeans. Compare with Exodus 30:34, where it is clearly named levonah, meaning either “white” or “Lebanese” in Hebrew.

The lost city of Ubar, sometimes identified with Irem in what is now the town of Shisr in Oman, is believed to have been a centre of the frankincense trade along the recently rediscovered “Incense Road”. Ubar was rediscovered in the early 1990s and is now under archaeological excavation.

The Greek historian Herodotus was familiar with Frankincense and knew it was harvested from trees in southern Arabia. He believed, however, that the gum was dangerous to harvest because of poisonous snakes that lived in the trees. He reports further that the snakes possesed wings and were not only capable of flight, but also went on an annual migration across the Red Sea to an area of Ethiopia they used for their breeding ground. It was only at this time that the gum could safely be taken.

Different Uses:

Frankincense is used in perfumery and aromatherapy. Olibanum essential oil is obtained by steam distillation of the dry resin. The smell of the olibanum smoke is due to the products of pyrolysis.

Frankincense was lavishly used in religious rites. In the Bible’s Old Testament, it was part of the temple rites; according to the Gospel of Matthew 2:11, gold, frankincense and myrrh were among the gifts to Jesus by the Biblical Magi “from out of the east”. The Egyptians ground the charred resin into a powder called kohl. Kohl was used to make the distinctive black eyeliner seen on so many figures in Egyptian art. The aroma of frankincense is said to represent life and the Judaic, Christian and Islamic faiths have often used frankincense mixed with oils to anoint newborn infants and individuals considered to be moving into a new phase in their spiritual lives.

The growth of Christianity, with an initial deritualisation of religion later to be reverted, depressed the market for frankincense during the 4th century AD. Desertification made the caravan routes across the Rub al Khali or “Empty Quarter” of Arabia more difficult. Additionally, increased raiding by the nomadic Parthians in the Near East caused the frankincense trade to dry up after about AD 300.
Constituents: Resins 65 per cent, volatile oil 6 per cent, water-soluble gum 20 per cent, bassorin 6 to 8 per cent, plant residue 2 to 4 per cent; the resins are composed of boswellic acid and alibanoresin.

Medicinal Action and Uses: It is stimulant, but seldom used now internally, though formerly was in great repute . Pliny mentions it as an antidote to hemlock. Avicenna (tenth century) recommends it for tumours, ulcers, vomiting, dysentery and fevers. In China it is used for leprosy.

Its principal use now is in the manufacture of incense and pastilles. It is also used in plasters and might be substituted for Balsam of Peru or Balsam or Tolu. The inhalation of steam laden with the volatile portion of the drug is said to relieve bronchitis and laryngitis.

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 (Gupta I, Gupta V, Parihar A, et al. Effects of Boswellia serrata gum resin in patients with bronchial asthma: results of a double-blind, placebo-controlled, 6-week clinical study. European Journal of Herbal Medicine 1998; 3:511-14.) In West Africa, the bark of Boswellia dalzielii is used to treat fever, rheumatism and gastro-intestinal problems (Arbonnier 2002. Arbres, arbustes et lianes des zones sÃ¨ches de l’Afrique de l’Ouest)

The ceremonial incense of the Jews was compounded of four ’sweet scents,’ of which pure Frankincense was one, pounded together in equal proportion. It is frequently mentioned in the Pentateuch. Pure Frankincense formed part of the meet offering and was also presented with the shew-bread every Sabbath day. With other spices, it was stored in a great chamber of the House of God at Jerusalem.

According to Herodotus, Frankincense to the amount of 1,000 talents weight was offered every year, during the feast of Bel, on the great altar of his temple in Babylon. The religious use of incense was as common in ancient Persia as in Babylon and Assyria. Herodotus states that the Arabs brought every year to Darius as tribute 1,000 talents of Frankincense, and the modern Parsis of Western India still preserve the ritual of incense.

Frankincense, though the most common, never became the only kind of incense offered to the gods among the Greeks. According to Pliny, it was not sacrificially employed in Trojan times. Among the Romans, the use of Frankincense (alluded to as mascula thura by Virgil in the Eclogues) was not confined to religious ceremonials. It was also used on state occasions, and in domestic life.

The kohl, or black powder with which the Egyptian women paint their eyelids, is made of charred Frankincense, or other odoriferous resin mixed with Frankincense. Frankincense is also melted to make a depilatory, and it is made into a paste with other ingredients to perfume the hands. A similar practice is described by Herodotus as having been practiced by the women of Scythia and is alluded to in Judith x. 3 and 4. In cold weather, the Egyptians warm their rooms with a brazier whereon incense is burnt, Frankincense, Benzoin and Aloe wood being chiefly used for the purpose.

The word ‘incense,’ meaning originally the aroma given off with the smoke of any odoriferous substance when burnt, has been gradually restricted almost exclusively to Frankincense, which has always been obtainable in Europe in greater quantity than any other of the aromatics imported from the East.

There is no fixed formula for the incense now used in the Christian churches of Europe, but it is recommended that Frankincense should enter as largely as possible intoits composition. In Rome, Olibanum alone is employed: in the Russian church, Benzoin is chiefly employed.

The following is a formula for an incense used in the Roman Church: Olibanum, 10 OZ. Benzoin, 4 oz. Storax, 1 OZ. Break into small pieces and mix.
