In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses mainly on naturally occurring resins.
Pistacia lentiscus is a dioecious evergreen shrub or small tree of the genus Pistacia native to the Mediterranean Basin. It grows up to 4 m (13 ft) tall and is cultivated for its aromatic resin, mainly on the Greek island of Chios, around the Turkish town of Çeşme and northern parts of Iraq.
Myrrh is a gum-resin extracted from a few small, thorny tree species of the Commiphora genus, belonging to the Burseraceae family. Myrrh resin has been used throughout history in medicine, perfumery, and incenses. Myrrh mixed with posca or wine was widely used in many ancient cultures to produce pleasurable feelings and as an anti-inflammatory and analgesic.
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. The word is from Old French franc encens. There are several species of Boswellia that produce true frankincense: Boswellia sacra, B. frereana, B. serrata, and B. papyrifera. Resin from each is available in various grades, which depends on the time of harvesting. The resin is hand-sorted for quality.
Boswellia is a genus of trees in the order Sapindales, known for its fragrant resin. The biblical incense frankincense is an extract from the resin of the tree Boswellia sacra, and is now produced also from B. frereana. Boswellia species are moderate-sized flowering plants, including both trees and shrubs.
The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of woody flowering plants. The actual numbers given in taxonomic sources differ according to taxonomic revision at the time of writing. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs; its species are native to tropical regions of Africa, Asia, Australasia, and the Americas.
Balm of Gilead was a rare perfume used medicinally that was mentioned in the Hebrew Bible and named for the region of Gilead, where it was produced. The expression stems from William Tyndale's language in the King James Bible of 1611 and has come to signify a universal cure in figurative speech. The tree or shrub producing the balm is commonly identified as Commiphora gileadensis. However, some botanical scholars have concluded that the actual source was a terebinth tree in the genus Pistacia.
Bdellium is a semi-transparent oleo-gum resin extracted from Commiphora wightii plants, and from Commiphora africana trees growing in sub-saharan Africa. According to Pliny the best quality came from Bactria. Other named sources for the resin are India, Pakistan, Arabia, Media, and Babylon.
Cordeauxia edulis is a plant in the family Fabaceae and the sole species in the genus Cordeauxia. Known by the common name yeheb bush, it is one of the economically most important wild plants of the Horn of Africa, but it is little known outside of its distribution area. It is a multipurpose plant, which allows the survival of nomads by providing them with seeds. Further, the bush serves forage for livestock, firewood and dye. Its wild population is currently declining. Because it is potentially valuable for other hot, dry regions as a resource for food and fodder, it is recommended to take measures against its extinction.
Commiphora is the most species-rich genus of flowering plants in the frankincense and myrrh family, Burseraceae. The genus contains approximately 190 species of shrubs and trees, which are distributed throughout the (sub-) tropical regions of Africa, the western Indian Ocean islands, the Arabian Peninsula, India, and South America. The genus is drought-tolerant and common throughout the xerophytic scrub, seasonally dry tropical forests, and woodlands of these regions.
Commiphora wightii, with common names Indian bdellium-tree, gugal, guggal, guggul, gugul, or mukul myrrh tree, is a flowering plant in the family Burseraceae, which produces a fragrant resin called gugal, guggul or gugul, that is used in incense and vedic medicine. The species is native to western India, from where it was introduced westward to southern Pakistan and the middle-east. It prefers arid and semi-arid climates and is tolerant of poor soil.
Commiphora myrrha, called myrrh, African myrrh, herabol myrrh, Somali myrrhor, common myrrh, is a tree in the family Burseraceae. It is one of the primary trees used in the production of myrrh, a resin made from dried tree sap. The tree is native to the Arabian Peninsula and to Africa. It is called 'mur' (المر) in Arabic, meaning bitter. It famously comes from Mecca, so it is called 'Mur Makki'.
Commiphora gileadensis, the Arabian balsam tree, is a shrub species in the genus Commiphora growing in Saudi Arabia, Yemen, southern Oman, Sudan and in southeast Egypt where it may have been introduced. Other common names for the plant include balm of Gilead and Mecca myrrh, but this is due to historical confusion between several plants and the historically important expensive perfumes and drugs obtained from them.
Hypericum gnidiifolium is a species of flowering plant in the family Hypericaceae. It is endemic to Ethiopia, where it has been observed at only two locations. It grows next to streams.
Boswellia papyrifera, also known as the Sudanese frankincense, is a species of flowering plant and frankincense that is native to Ethiopia, Eritrea and Sudan. The tree is cultivated in Ethiopia because of its valuable resin. The incense is characterized by a fresh lemon-pine scent and is therefore highly esteemed. In Ethiopia where it is called itan zaf, it comes in semi-translucent yellow tears. The gum resin of Boswellia papyrifera coming from Ethiopia, Sudan and eastern Africa is believed to be the main source of frankincense of antiquity.
Stacte and nataph are names used for one component of the Solomon's Temple incense, the Ketoret, specified in the Book of Exodus. Variously translated to the Greek term or to an unspecified "gum resin" or similar, it was to be mixed in equal parts with onycha, galbanum and mixed with pure frankincense and they were to "beat some of it very small" for burning on the altar of the tabernacle.
Commiphora africana, commonly called African myrrh, is a small deciduous tree belonging to the Burseraceae, a family akin to the Anacardiaceae, occurring widely over sub-Saharan Africa in Angola, Botswana, Burkina Faso, Chad, Eswatini, Eritrea, Ethiopia, Kenya, Mali, Mauritania, Mozambique, Namibia, Niger, Senegal, Somalia, South Africa, Sudan, Tanzania, Uganda, Zambia and Zimbabwe. On sandy soils this species sometimes forms pure stands, deserving consideration as a plant community or association.
Curzerene is a volatile, aromatic terpenoid found in many herbs and spices, such as Curcuma zeodaria. It is a bioactive isolate of Caribbean corals and is also found in myrrh. More specifically it has been found to make up a significant portion - 12.97% - of the smoke produced from burning Commiphora myrrha oleo gum resin. It is also a major component of myrrh oil, which has been shown in vitro to possess anti-inflammatory properties at sub-toxic by inhibiting the production of the inflammatory cytokine IL-6 by human gingival fibroblasts. Anecdotal evidence exists to support the anti-inflammatory effect of myrrh oil.
Opopanax is the commercial name of bisabol or bissabol, the fragrant oleo-gum-resin of Commiphora guidottii. It has been a major export article from Somalia since ancient times, and is called hebbakhade, habaghadi or habak hadi in Somali. It is an important ingredient in perfumery and therefore known as scented myrrh, sweet myrrh, perfumed myrrh or perfumed bdellium.
Myrrh is a natural gum or resin extracted from a number of small, thorny tree species of the genus Commiphora.
