Monarda Didyma
''Monarda didyma'', the crimson beebalm, scarlet beebalm, scarlet monarda, Eau-de-Cologne plant, Oswego tea, or bergamot, is an aromatic herb in the family Lamiaceae, native to eastern North America from Maine west to Ontario and Minnesota, and south to northern Georgia. Its odor is considered similar to that of the bergamot orange (used to flavor Earl Grey tea). The genus name comes from Nicolas Monardes, who described the first American flora in 1569. Description ''M. didyma'' is a perennial plant that grows to 0.6-1.2 m in height and spreads 0.4-0.6 m. The 7–18 cm long, ovate to ovate-lanceolate leaves with serrate margins are medium to deep green, placed opposite on square, hollow stems. The leaves are minty fragrant when crushed. It has ragged, bright red tubular flowers 3–4 cm long, borne on showy heads of about 30 together, with reddish bracts. It grows in dense clusters along stream banks, moist thickets, and ditches, blooming for about 8 weeks from early/m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bergamot Orange
''Citrus bergamia'', the bergamot orange (pronounced ), is a fragrant citrus fruit the size of an orange, with a yellow or green color similar to a lime, depending on ripeness. Genetic research into the ancestral origins of extant citrus cultivars found bergamot orange to be a probable hybrid of lemon and bitter orange. Extracts have been used as an aromatic ingredient in food, tea, snus, perfumes, and cosmetics. Use on the skin can increase photosensitivity, resulting in greater damage from sun exposure. Etymology The word bergamot is derived from the Italian word , derived either from the Italian town of Bergamo or Ottoman Turkish ("prince's pear"). Description ''Citrus bergamia'' is a small tree that blossoms during the winter. The juice tastes less sour than lemon, but more bitter than grapefruit. Phytochemicals Bergamot fruit or oil contains flavonoids, such as neoeriocitrin, naringin, neohesperidin, ponceritin, melitidin, mitrocin, miriflin, brutieridin, and berga ...

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouthwash
Mouthwash, mouth rinse, oral rinse, or mouth bath is a liquid which is held in the mouth passively or swilled around the mouth by contraction of the perioral muscles and/or movement of the head, and may be gargling, gargled, where the head is tilted back and the liquid bubbled at the back of the mouth. Usually mouthwashes are antiseptic solutions intended to reduce the microbial load in the mouth, although other mouthwashes might be given for other reasons such as for their analgesic, anti-inflammatory or anti-fungal medication, anti-fungal action. Additionally, some rinses act as saliva substitutes to neutralize acid and keep the mouth moist in xerostomia (dry mouth). Cosmetic mouthrinses temporarily control or reduce bad breath and leave the mouth with a pleasant taste. Rinsing with water or mouthwash after brushing with a Toothpaste#Fluorides, fluoride toothpaste can reduce the availability of salivary fluoride. This can lower the anti-cavity re-mineralization and antibacteri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thymol
Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), , is a natural monoterpenoid phenol derivative of ''p''-Cymene, isomeric with carvacrol, found in oil of thyme, and 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: : History Ancient Egyptians used thyme for embalming. The ancient Greeks used it in their baths and burned it as ince ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gingivitis
Gingivitis is a non-destructive disease that causes inflammation of the gums. The most common form of gingivitis, and the most common form of periodontal disease overall, is in response to bacterial biofilms (also called plaque) that is attached to tooth surfaces, termed ''plaque-induced gingivitis''. Most forms of gingivitis are plaque-induced. While some cases of gingivitis never progress to periodontitis, periodontitis is always preceded by gingivitis. Gingivitis is reversible with good oral hygiene; however, without treatment, gingivitis can progress to periodontitis, in which the inflammation of the gums results in tissue destruction and bone resorption around the teeth. Periodontitis can ultimately lead to tooth loss. Signs and symptoms The symptoms of gingivitis are somewhat non-specific and manifest in the gum tissue as the classic signs of inflammation: *Swollen gums *Bright red gums *Gums that are tender or painful to the touch *Bleeding gums or bleeding after bru ...

Caries
Tooth decay, also known as cavities or caries, is the breakdown of teeth due to acids produced by bacteria. The cavities may be a number of different colors from yellow to black. Symptoms may include pain and difficulty with eating. Complications may include inflammation of the tissue around the tooth, tooth loss and infection or abscess formation. The cause of cavities is acid from bacteria dissolving the hard tissues of the teeth ( enamel, dentin and cementum). The acid is produced by the bacteria when they break down food debris or sugar on the tooth surface. Simple sugars in food are these bacteria's primary energy source and thus a diet high in simple sugar is a risk factor. If mineral breakdown is greater than build up from sources such as saliva, caries results. Risk factors include conditions that result in less saliva such as: diabetes mellitus, Sjögren syndrome and some medications. Medications that decrease saliva production include antihistamines and antidepre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbal Tea
Herbal teas, also 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. Oftentimes herb tea, or the plain term ''tea'', is used as a reference to all sorts of herbal teas. Many herbs are used in herbal medicine. Some herbal blends contain actual tea (e.g., the Indian classic masala chai). The term "herbal" tea is often used in contrast to the so-called ''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 (which are also available decaffeinated), most tisanes do not naturally contain caffeine. There are a number of plants, however, that ''do'' contain caffeine or another stimulant, like theobromine, cocaine or ephedrine. Some have the opposite effect, acting as a sedative. Some common infusions have specific names such as , ''mate'' (ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackfoot Confederacy
The Blackfoot Confederacy, ''Niitsitapi'' or ''Siksikaitsitapi'' (ᖹᐟᒧᐧᒣᑯ, meaning "the people" or " Blackfoot-speaking real people"), is a historic collective name for linguistically related groups that make up the Blackfoot or Blackfeet people: the ''Siksika'' ("Blackfoot"), the '' Kainai or Blood'' ("Many Chiefs"), and two sections of the Peigan or Piikani ("Splotchy Robe") – the Northern Piikani (''Aapátohsipikáni'') and the Southern Piikani (''Amskapi Piikani'' or ''Pikuni''). Broader definitions include groups such as the ''Tsúùtínà'' ( Sarcee) and ''A'aninin'' (Gros Ventre) who spoke quite different languages but allied with or joined the Blackfoot Confederacy. Historically, the member peoples of the Confederacy were nomadic bison hunters and trout fishermen, who ranged across large areas of the northern Great Plains of western North America, specifically the semi-arid shortgrass prairie ecological region. They followed the bison herds as they mig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...
