Gum Ammoniac
Ammoniacum or the gum ammoniac is a gum-resin exuded from the several perennial herbs in the genus ''Ferula'' of the umbel family (Apiaceae). There are three types of ammoniacum: the gums ammoniac of Cyrenaica, of Persia (the commercial one today), and of Morocco. Ammoniac of Cyrenaica Ammoniacum was first documented in the 1st century by Dioscorides in his ''De materia medica''. It got its name from the Temple of Jupiter Ammon in ancient Libya (located in the Siwa Oasis of Egypt today) near which it was produced. It is called the gum ammoniac of Cyrenaica to differentiate it from the commercial one used today, and its source plant has been identified as ''Ferula marmarica'' native to Libya and Egypt. The export of the gum ammoniac of Cyrenaica to Europe declined after Arab and Turk domination of the Middle East, but probably continued at least until the 18th century, as Linnaeus still cited Libya and Egypt as the places of origin of ammoniacum in his ''Materia medica''.

Gum (botany)
Gum is a sap or other resinous material associated with certain species of the plant kingdom. This material is often polysaccharide-based and is most frequently associated with woody plants, particularly under the bark or as a seed coating. The polysaccharide material is typically of high molecular weight and most often highly hydrophilic or hydrocolloidal. As seed coating Many gums occur as seed coatings for plant species; the adaptive purpose of some of these gummy coatings is to delay germination of certain flora seeds. An example of such a gummy coating occurs in the case of Western poison oak, a widespread shrub in western North America. See also * Cambium * Gummosis * Latex * Natural gum Natural gums are polysaccharides of natural origin, capable of causing a large increase in a solution's viscosity, even at small concentrations. They are mostly botanical gums, found in the woody elements of plants or in seed coatings. Human u ... Line notes * Plant physiology ...

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

Umbelliferone
Umbelliferone, also known as 7-hydroxycoumarin, hydrangine, skimmetine, and ''beta''-umbelliferone, is a natural product of the coumarin family. It absorbs ultraviolet light strongly at several wavelengths. There are some indications that this chemical is antimutagenic, it is used in sunscreens. Umbelliferone has been reported to have antioxidant properties. It is a yellowish-white crystalline solid that has a slight solubility in hot water, but high solubility in ethanol. Natural occurrences and name Umbelliferone's name is from the umbelliferae family of plants, and the plant family in turn was named for their umbrella-shaped inflorescences, each called an umbel. Umbelliferone occurs in many familiar plants from the Apiaceae (Umbelliferae) family such as carrot, coriander and garden angelica, as well as in plants from other families, such as the mouse-ear hawkweed (''Hieracium pilosella'', Asteraceae) or the bigleaf hydrangea (''Hydrangea macrophylla'', Hydrangeaceae, under ...

Galbanum
Galbanum is an aromatic gum resin and a product of certain umbelliferous Persian plant species in the genus ''Ferula'', chiefly ''Ferula gummosa'' (synonym ''F. galbaniflua'') and ''Ferula rubricaulis''. Galbanum-yielding plants grow plentifully on the slopes of the mountain ranges of northern Iran. It occurs usually in hard or soft, irregular, more or less translucent and shining lumps, or occasionally in separate tears, of a light-brown, yellowish or greenish-yellow colour. Galbanum has a disagreeable, bitter taste, a peculiar, a somewhat musky odour, and an intense green scent. With a specific gravity of 1.212, it contains about 8% terpenes; about 65% of a resin which contains sulfur; about 20% gum; and a very small quantity of the colorless crystalline substance umbelliferone. It also contains α-pinene, β-pinene, limonene, cadinene, 3-carene, and ocimene. Uses Biblical use In the Book of Exodus 30:34, it is mentioned as being used in the making of the ''Ketoret'' whic ...

Asafoetida
Asafoetida (; also spelled asafetida) is the dried latex ( gum oleoresin) exuded from the rhizome or tap root of several species of ''Ferula'', perennial herbs growing tall. They are part of the celery family, Umbelliferae. Asafoetida is thought to be in the same genus as silphium, a North African plant now believed to be extinct, and was used as a cheaper substitute for that historically important herb from classical antiquity. The species are native to the deserts of Iran and mountains of Afghanistan where substantial amounts are grown. Asafoetida has a pungent smell, as reflected in its name, lending it the trivial name of "stinking gum". The odor dissipates upon cooking; in cooked dishes, it delivers a smooth flavour reminiscent of leeks or other onion relatives. Asafoetida is also known colloquially as "devil's dung" in English (and similar expressions in many other languages). Etymology and other names The English name is derived from ''asa'', a latinised form of Pers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unpleasant Odor
An odor (American English) or odour (Commonwealth English; see spelling differences) is caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive via their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor. While "odor" and "smell" can refer to pleasant and unpleasant odors, the terms "scent", "aroma", and "fragrance" are usually reserved for pleasant-smelling odors and are frequently used in the food and cosmetic industry to describe floral scents or to refer to perfumes. Physiology of smell Sense of smell The perception of odors, or sense of smell, is mediated by the olfactory nerve. The olfactory receptor (OR) cells are neurons present in the olfactory epithelium, which is a small patch of tissue at the back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling cells. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
