Thyme
Thyme () is a culinary herb consisting of the dried aerial parts of some members of the genus ''Thymus (plant), Thymus'' of flowering plants in the mint family Lamiaceae. Thymes are native to Eurasia and north Africa. Thymes have culinary, medicinal, and ornamental uses. The species most commonly cultivated and used for culinary purposes is ''Thymus vulgaris'', native to Southeast Europe. History Thymus serpyllum, Wild thyme grows in the Levant, where it might have been first cultivated. Ancient Egyptians used common thyme (''Thymus vulgaris'') for embalming. The Ancient Greece, ancient Greeks used it in their baths and burnt it as incense in their temples, believing it was a source of courage. The spread of thyme throughout Europe was thought to be due to the Ancient Rome, Romans, as they used it to purify their rooms and to "give an aromatic flavour to cheese and liqueurs". In the European Middle Ages, the herb was placed beneath pillows to aid sleep and ward off nightmares ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Thymus (plant)
The genus ''Thymus'' ( ; thymes) contains about 350 species of aromatic perennial plant, perennial herbaceous plants and subshrubs in the family Lamiaceae. It is native to the Old World. Several members of the genus are cultivated as culinary herbs or ornamentals, when they are also called thyme after its best-known species, ''Thymus vulgaris'' or common thyme. Description The plants grow up to tall. The stems tend to be narrow or even wiry. The leaves are evergreen in most species, arranged in opposite pairs, oval, entire, and small, long, and usually aromatic. Thyme flowers are in dense terminal heads with an uneven sepal, calyx, with the upper lip three-lobed, and are yellow, white, or purple. Classification A considerable amount of confusion has existed in the naming of thymes. Many nurseries use common names rather than binomial names, which can lead to mix-ups. For example ''golden thyme'', ''lemon thyme'', and ''creeping thyme'' are all common names for more than one c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Thymus Serpyllum
''Thymus serpyllum'', known by the common names of Breckland thyme, Breckland wild thyme, wild thyme, creeping thyme, or elfin thyme, is a species of flowering plant in the mint family, Lamiaceae. It is a low, usually prostrate subshrub forming creeping stems up to tall. The oval evergreen leaves are up to 8 mm. The strongly scented flowers are either lilac, pink-purple, magenta, up to 6 mm long and produced in clusters. The species is native to most of Europe and North Africa. The hardy plant tolerates some pedestrian traffic and produces odors ranging from heavily herbal to lightly lemon, depending on the variety. Description Wild thyme is a creeping dwarf evergreen shrub, growing to tall. It has woody stems up to 10 cm long and a taproot. It forms matlike plants that root from the nodes of the squarish, limp stems. The leaves are 3–8 mm long in opposite pairs, nearly stalkless, with linear elliptic round-tipped blades and untoothed margins. The plan ...

Thymol
Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), , is a toxic monoterpenoid phenol derivative of ''p''-Cymene, isomeric with carvacrol. It occurs naturally in the oil of thyme, and it is extracted from ''Thymus vulgaris'' (common thyme), ajwain, and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. Thymol also provides the distinctive, strong flavor of the culinary herb thyme, also produced from ''T. vulgaris''. Thymol is only slightly soluble in water at neutral pH, but it is extremely soluble in alcohols and other organic solvents. It is also soluble in strongly alkaline aqueous solutions due to deprotonation of the phenol. Its dissociation constant ( p''K''a) is . Thymol absorbs maximum UV radiation at 274 nm. Chemical synthesis Thymol is produced by the alkylation of ''m''-cresol and propene: : A predicted method of biosynthesis of thymol in thyme and oregano begins with the cyclizati ...

Thymus Vulgaris
''Thymus vulgaris'' (common thyme, German thyme, garden thyme or just thyme) is a species of flowering plant in the mint family (biology), family Lamiaceae, native plant, native to southern Europe from the western Mediterranean to southern Italy. Growing to tall by wide, it is a bushy, woody-based evergreen subshrub with small, highly aromatic, grey-green leaves and clusters of purple or pink flowers in early summer. It is useful in the garden as groundcover, where it can be short-lived, but is easily plant propagation, propagated from cuttings. It is also the main source of thyme as an ingredient in cooking and as a herbal medicine. It is slightly spicier than oregano and sweeter than Salvia officinalis, sage. The Latin binomial nomenclature, specific epithet ''vulgaris'' means “common” in the sense of “widespread”. Cultivars Numerous cultivars and Hybrid (biology)#Hybrid plants, hybrids have been developed for ornamental purposes. Nomenclature can be very confus ...

Perennial
In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of the local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a peren ...

Culinary Herb
Herbs are a widely distributed and widespread group of plants, excluding vegetables, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. ''Herbs'' generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while ''spices'' are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits. Herbs have a variety of uses including culinary, medicinal, aromatic and in some cases, spiritual. General usage of the term "herb" differs between culinary herbs and medicinal herbs; in medicinal or spiritual use, any parts of the plant might be considered "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin and pericarp. The word "herb" is pronounced in Commonwealth English, but is standard among American English speakers as well as those from regions whe ...

Tisane
Herbal teas, technically known as herbal infusions, and less commonly called tisanes (UK and US , US also ), are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. Often herb tea, or the plain term ''tea'', is used as a reference to all sorts of herbal teas. Many herbs used in teas/tisanes are also used in herbal medicine and in folk medicine. These "teas" do not usually contain any true ''tea'' (''Camellia sinensis''), but some herbal blends do contain true tea (e.g., the Indian classic masala chai). The term "herbal" tea is often used to distinguish these beverages from "true" teas (e.g., black, green, white, yellow, oolong), which are prepared from the cured leaves of the tea plant, ''Camellia sinensis''. Unlike true teas, most tisanes do not naturally contain caffeine (though tea can be decaffeinated, i.e., processed to remove caffeine). A number of plants, however, ''do'' contain psychoactive compounds, such as caffeine o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Funerals
A funeral is a ceremony connected with the final disposition of a corpse, such as a burial or cremation, with the attendant observances. Funerary customs comprise the complex of beliefs and practices used by a culture to remember and respect the dead, from interment, to various monuments, prayers, and rituals undertaken in their honour. Customs vary between cultures and religious groups. Funerals have both normative and legal components. Common secular motivations for funerals include mourning the deceased, celebrating their life, and offering support and sympathy to the bereaved; additionally, funerals may have religious aspects that are intended to help the soul of the deceased reach the afterlife, resurrection or reincarnation. The funeral usually includes a ritual through which the corpse receives a final disposition. Depending on culture and religion, these can involve either the destruction of the body (for example, by cremation, sky burial, decomposition, disintegration ...

Bouquet Garni
The ''bouquet garni'' ( French for "garnished bouquet"; ) is a bundle of herbs usually tied with string and mainly used to prepare soup, stock, casseroles and various stews. The bouquet is cooked with the other ingredients and removed prior to consumption. Liquid remaining in the bouquet garni can be wrung out into the dish. There is no standard recipe for ''bouquet garni'', but most French recipes include thyme, bay leaf and parsley. It may also include basil, burnet, chervil, rosemary, peppercorns, savory and tarragon. Vegetables such as carrot, celery (leaves or leaf stalks), celeriac, leek, onion and parsley root are sometimes included in the ''bouquet''. Sometimes, the ''bouquet'' is not bound with string, and its ingredients are filled into a small sachet, a piece of celery stalk, a net, or a tea strainer instead. Traditionally, the aromatics are bound within leek leaves, though a cheesecloth, muslin or coffee filter tied with butcher twine can be used. ''Sachet ...

Gas Chromatographic Analysis
Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. In preparative chromatography, GC can be used to prepare pure compounds from a mixture. Gas chromatography is also sometimes known as vapor-phase chromatography (VPC), or gas–liquid partition chromatography (GLPC). These alternative names, as well as their respective abbreviations, are frequently used in scientific literature. Gas chromatography is the process of separating compounds in a mixture by injecting a gaseous or liquid sample into a mobile phase, typically called the carrier gas, and passing the gas through a stationary phase. The mobile phase is usually an inert gas or an unreactive gas such as helium, argon, nitrogen or hydrogen. The stationary phase can be solid or li ...
