Swallowwort
Swallowwort or swallow-wort is a common name for several plants and plant families. The term may be a description of poisonous effects, or indicate that a plant was formerly used medicinally for tonsillitis. It may refer to: * Any of several vines of the genus ''Vincetoxicum'', especially white swallowwort (''Vincetoxicum hirundinaria''), black swallowwort (''Vincetoxicum nigrum''), and pale swallowwort ('' Vincetoxicum rossicum'') * Any of several vines of the genus ''Cynanchum''. ''Cynanchum'' is from Greek words meaning "to choke a dog." * Greater celandine (''Chelidonium majus''). * Greater celandine and swallowwort were each often categorized with tetterworts because they were used to treat tetter. This led to nomenclature confusion among these worts. * many plants of the genus ''Asclepias'' * ''Euphorbia maculata'' * '' Seutera angustifolia'', a plant of the genus ''Seutera ''Seutera'' is a genus of plants in the family Apocynaceae, first described as a genus in 1828.

Vincetoxicum Rossicum
''Vincetoxicum rossicum'' is a flowering plant in the family Apocynaceae. It is a perennial herb native to southern Europe and is a highly invasive plant growing in all of the Eastern United States, in the mid west, and southern Ontario and Quebec in Canada. It has several common names including swallowwort, pale swallowwort, and dog-strangling vine. There has historically been much confusion about the genus it belongs to, with authors placing it within ''Vincetoxicum'' and others within ''Cynanchum'', but recent molecular and chemical analyses have shown it to belong in the genus ''Vincetoxicum''. Description Leaves The leaves of the pale swallowwort are larger when they are closer to the stem and decrease in size as they move away from the stem. They are in the shape of an ellipse or an oval and contain smooth margins and major veins underneath. The glossy, dark green leaves grow opposite on the stem and are ovate to elliptical. The flowers appear near the top of the plant and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynanchum
''Cynanchum'' is a genus of about 300 species including some swallowworts, belonging to the family Apocynaceae. The taxon name comes from Greek ''kynos'' (meaning "dog") and ''anchein'' ("to choke"), hence the common name for several species is dog-strangling vine. Most species are non-succulent climbers or twiners. There is some evidence of toxicity. Morphology These plants are perennial herbs or subshrubs, often growing from rhizomes. The leaves are usually oppositely arranged and sometimes are borne on petioles. The inflorescences and flowers come in a variety of shapes. Like other species of the milkweed family, these plants bear follicles, which are podlike dry fruits. Distribution These species are found throughout the tropics and subtropics. Several species also grow in temperate regions. Importance The root of '' Cynanchum atratum'' is used in Chinese traditional medicine and called ''Bai wei''. Several other species had traditional Chinese medicinal uses. ''Cynanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Celandine
''Chelidonium majus'', the greater celandine, is a perennial herbaceous flowering plant in the poppy family Papaveraceae. One of two species in the genus ''Chelidonium'', it is native to Europe and western Asia and introduced widely in North America. The plant known as lesser celandine (''Ficaria verna'') is not closely related, as it belongs to the buttercup family Ranunculaceae. Description Greater celandine is a perennial herbaceous plant with an erect habit, and reaches high. The blue-green leaves are pinnate with lobed and wavy margins, up to long. When injured, the plant exudes a yellow to orange latex. The flowers consist of four yellow petals, each about long, with two sepals. A double-flowered variety occurs naturally. The flowers appear from late spring to summer, May to September (in the UK), in umbelliform cymes of about 4 flowers. The seeds are small and black, borne in a long, cylindrical capsule. Each has an elaiosome, which attracts ants to disperse the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asclepias
''Asclepias'' is a genus of herbaceous, perennial, flowering plants known as milkweeds, named for their latex, a milky substance containing cardiac glycosides termed cardenolides, exuded where cells are damaged. Most species are toxic to humans and many other species, primarily due to the presence of cardenolides, although, as with many such plants, there are species that feed upon them (e.g. their leaves) and from them (e.g. their nectar). Most notable are monarch butterflies, who use and require certain milkweeds as host plants for their larvae. The genus contains over 200 species distributed broadly across Africa, North America, and South America. It previously belonged to the family Asclepiadaceae, which is now classified as the subfamily Asclepiadoideae of the dogbane family, Apocynaceae. The genus was formally described by Carl Linnaeus in 1753, who named it after Asclepius, the Greek god of healing. Flowers Members of the genus produce some of the most complex flowe ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Tonsillitis
Tonsillitis is inflammation of the tonsils in the upper part of the throat. It can be acute or chronic. Acute tonsillitis typically has a rapid onset. Symptoms may include sore throat, fever, enlargement of the tonsils, trouble swallowing, and enlarged lymph nodes around the neck. Complications include peritonsillar abscess. Tonsillitis is most commonly caused by a viral infection and about 5% to 40% of cases are caused by a bacterial infection.Lang 2009p. 2083./ref> When caused by the bacterium group A streptococcus, it is classed as streptococcal tonsillitis also referred to as ''strep throat''. Rarely bacteria such as '' Neisseria gonorrhoeae'', '' Corynebacterium diphtheriae'', or ''Haemophilus influenzae'' may be the cause. Typically the infection is spread between people through the air. A scoring system, such as the Centor score, may help separate possible causes. Confirmation may be by a throat swab or rapid strep test. Treatment efforts involve improving symptoms and ...

Vincetoxicum
''Vincetoxicum'' is a genus of plants in the family Apocynaceae. Although the species in ''Vincetoxicum'' have sometimes been included in ''Cynanchum'', chemical and molecular evidence shows that ''Vincetoxicum'' is more closely related to ''Tylophora''. The generic name means "poison-beater" in Botanical Latin because of the plants' supposed antidotal effects against snakebite. ;Species ;formerly included moved to other genera ( Alexitoxicon, Ampelamus, Antitoxicum, Asclepias, Blyttia, Cynanchum, Dictyanthus, Diplolepis, Gonolobus, Heterostemma, Ischnostemma, Macroscepis, Matelea, Orthosia, Pentatropis, Petalostelma, Polystemma, Seutera, Telminostelma, Tylophora ''Tylophora'' is a genus of climbing plant or vine, first described as a genus in 1810.
