Wintergreen
Wintergreen is a group of aromatic plants. The term "wintergreen" once commonly referred to plants that remain green (continue photosynthesis) throughout the winter. The term "evergreen" is now more commonly used for this characteristic. Most species of the shrub genus ''Gaultheria'' demonstrate this characteristic and are called wintergreens in North America, the most common generally being the American wintergreen ('' Gaultheria procumbens''). Wintergreens in the genus ''Gaultheria'' contain an aromatic compound, methyl salicylate, and are used as a mintlike flavoring. Uses The berries of most species can be eaten raw or used in pies. Wintergreen is a common flavoring in American products ranging from chewing gum, mints, and candies to smokeless tobacco such as dipping tobacco (American "dip" snuff) and snus. It is a common flavoring for dental hygiene products such as mouthwash and toothpaste. It is often a component of the American-origin drink root beer. Wintergreen o ...

Smokeless Tobacco
Smokeless tobacco is a tobacco product that is used by means other than smoking. Their use involves chewing, sniffing, or placing the product between gum and the cheek or lip. Smokeless tobacco products are produced in various forms, such as chewing tobacco, snuff, snus, and dissolvable tobacco products. Smokeless tobacco products typically contain over 3000 constituents. All smokeless tobacco products contain nicotine and are therefore highly addictive. Quitting smokeless tobacco use is as challenging as smoking cessation. Smokeless tobacco is much lower on the risk continuum than combusted products but varies in risk within that class of products (e.g., low nitrosamine Swedish-type snus versus other smokeless tobacco with high nitrosamine levels). It is estimated the safety risk of smokeless tobacco is similar to that of electronic cigarettes. There is no safe level of smokeless tobacco use. It is correlated with a number of adverse effects such as dental disease, oral canc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaultheria Procumbens
''Gaultheria procumbens'', also called the eastern teaberry, the checkerberry, the boxberry, or the American wintergreen, is a species of ''Gaultheria'' native to northeastern North America from Newfoundland west to southeastern Manitoba, and south to Alabama. It is a member of the Ericaceae (heath family). Growth and habitat ''G. procumbens'' is a small, low-growing shrub, typically reaching tall. The leaves are evergreen, elliptic to ovate, long and broad, with a distinct oil of wintergreen scent. The flowers are pendulous, with a white, sometimes pink-tinged, bell-shaped corolla with five teeth at the tip long, and above it a white calyx. They are borne in leaf axils, usually one to three per stem. The anthers are forked somewhat like a snake's tongue, with two awns at the tip. The fruit is red and across. It is an epigynous berry, with the majority of the flesh of the fruit being composed of the fleshy calyx. The plant is a calcifuge, favoring acidic soil, in pin ...

Methyl Salicylate
Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic compound with the formula C8H8O3. It is the methyl ester of salicylic acid. It is a colorless, viscous liquid with a sweet, fruity odor reminiscent of root beer, but often associatively called "minty", as it is an ingredient in mint candies. It is produced by many species of plants, particularly wintergreens. It is also produced synthetically, used as a fragrance and as a flavoring agent. Biosynthesis and occurrence Methyl salicylate was first isolated (from the plant '' Gaultheria procumbens'') in 1843 by the French chemist Auguste André Thomas Cahours (1813–1891), who identified it as an ester of salicylic acid and methanol. The biosynthesis of methyl salicylate arises via the hydroxylation of benzoic acid by a cytochrome P450 followed by methylation by a methylase enzyme. Methyl salicylate as a plant metabolite Many plants produce methyl salicylate in small quantities. Methyl salicylate levels ar ...

Aromatic Plant
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does ''not'' mean indispensable or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, '' sfumatura'', absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soaps, ...

Dipping Tobacco
Dipping tobacco is a type of finely ground or shredded, moistened smokeless tobacco product. It is commonly and idiomatically known as "dip". Dipping tobacco is used by placing a pinch, or "dip", of tobacco between the lip and the gum ( sublabial administration). The act of using it is called ''dipping''. Dip is colloquially called "chaw", "snuff", "rub", or "fresh leaf" among other terms; because of this, it is sometimes confused with other tobacco products—namely nasal/ dry snuff. History Dipping tobacco evolved from the use of dry snuff in early American history. Up until the late 1700s, dry snuff was taken nasally, but then early Americans would take snuff orally by chewing the end of a twig until it resembled a brush, and then "dipping" the twig in the snuff and placing it in their mouths until the snuff dissolved. Using dry snuff orally eventually evolved into modern day moist snuff, which Copenhagen introduced in 1822 and then Skoal started producing in 1934. Mo ...

Firearm Maintenance
Firearm maintenance (or gun care for short) is a series of routine preventive maintenance procedures aiming to ensure the proper function of a firearm, often with the use of a variety of specialized tools and chemical solutions. Typically such maintenance is performed by the firearm owner using either simple methods such as cleaning the firearm with oil or other cleaning solutions or more sophisticated practices such as lubricating moving parts with oil/grease and recoating exposed surfaces with protective finishes such as varnishing or bluing. When a firearm is presented with physical damage related to the ordinary use of the firearm, or when a firearm malfunctions in a life-threatening manner, a professional gunsmith should perform advanced maintenance to determine if the firearm is repairable and or safe to shoot anymore. Necessity An inadequately maintained firearm will often accumulate excessive fouling and dirt within the barrel and receiver, which not only can clo ...

Vegetable Oils
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of fruits. Like animal fats, vegetable fats are ''mixtures'' of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of fruits. In common usage, vegetable ''oil'' may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible. Uses In antiquity Oils extracted from plants have been used since ancient times and in many cultures. Archaeological evidence shows that olives were turned into olive oil by 6000 BCE and 4500 BCE in present-day Israel and Palestine. In addition to use as food, fats and oils (both vegetable and mineral) have long been used as fuel, typically in lamps which were a principal source of illumination in ancient times. Oils may have been used for lubrication, but there is no evidence for this. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firearms
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toothpaste
Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and health of teeth. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay ( dental caries) and gum disease (gingivitis).American Dental Association Description of Toothpaste Owing to differences in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes worldwide. Large amounts of swallowed toothpaste can be toxic. Common colors for toothpaste include white (sometimes with colored stripes or green tint) and blue. Usefulness Toothpastes are generally useful to maintain dental health. Toothpastes containing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Non-toxic
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell ( cytotoxicity) or an organ such as the liver (hepatotoxicity). By extension, the word may be metaphorically used to describe toxic effects on larger and more complex groups, such as the family unit or society at large. Sometimes the word is more or less synonymous with poisoning in everyday usage. A central concept of toxicology is that the effects of a toxicant are dose-dependent; even water can lead to water intoxication when taken in too high a dose, whereas for even a very toxic substance such as snake venom there is a dose below which there is no detectable toxic effect. Toxicity is species-specific, making cross-species analysis problematic. Newer paradigms and metrics are evolving to bypa ...
