Ipomoea Pandurata
''Ipomoea pandurata'', known as man of the earth, wild potato vine, manroot, wild sweet potato, and wild rhubarb, is a species of herbaceous perennial vine native to North America. It is a twining plant of woodland verges and rough places with heart-shaped leaves and funnel-shaped white flowers with a pinkish throat. The large tuberous roots can be roasted and eaten, or can be used to make a poultice or infusion. When uncooked, the roots have purgative properties.Peterson, Lee, ''A Field Guide to Edible Wild Plants of Eastern and Central North America'', p. 20, Houghton Mifflin Company, New York City, accessed 22 November 2010. Description ''I. pandurata'' is a twining and scrambling vine that can reach . The stems are usually hairless and bear alternate, olive-green, cordate leaves, about long, with long, purple-tinged petioles. The flowers develop in the axils of the leaves in groups of one to five. The sepals are light green and hairless, and overlap one another. The flowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectar
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps (e.g. the social wasp species ''Apoica flavissima'') rely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laxative
Laxatives, purgatives, or aperients are substances that loosen stools and increase bowel movements. They are used to treat and prevent constipation. Laxatives vary as to how they work and the side effects they may have. Certain stimulant, lubricant and saline laxatives are used to evacuate the colon for rectal and bowel examinations, and may be supplemented by enemas under certain circumstances. Sufficiently high doses of laxatives may cause diarrhea. Some laxatives combine more than one active ingredient. Laxatives may be administered orally or rectally. Types Bulk-forming agents Bulk-forming laxatives, also known as roughage, are substances, such as fiber in food and hydrophilic agents in over-the-counter drugs, that add bulk and water to stools so that they can pass more easily through the intestines (lower part of the digestive tract). Properties * Site of action: small and large intestines * Onset of action: 12–72 hours * Examples: dietary fiber, Metamucil, Citru ...

Diuretic
A diuretic () is any substance that promotes diuresis, the increased production of urine. This includes forced diuresis. A diuretic tablet is sometimes colloquially called a water tablet. There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys. There exist several classes of diuretic, and each works in a distinct way. Alternatively, an antidiuretic, such as vasopressin ( antidiuretic hormone), is an agent or drug which reduces the excretion of water in urine. Medical uses In medicine, diuretics are used to treat heart failure, liver cirrhosis, hypertension, influenza, water poisoning, and certain kidney diseases. Some diuretics, such as acetazolamide, help to make the urine more alkaline, and are helpful in increasing excretion of substances such as aspirin in cases of overdose or poisoning. Diuretics are sometimes abused by people with an eating disorder, especially people with bulimia nervosa, with the goa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucokinetics
Mucoactive agents are a class of chemical agents that aid in the clearance of mucus or sputum from the upper and lower airways, including the lungs, bronchi, and trachea. Mucoactive drugs include expectorants, mucolytics, mucoregulators, and mucokinetics. These medications are used in the treatment of respiratory diseases that are complicated by the oversecretion or inspissation of mucus. These drugs can be further categorized by their mechanism of action. Mechanism of action Mucoactive agents - expectorants – include mucolytics, secretolytics and mucokinetics (also called secretomotorics) * Mucolytics – thin (reduce the viscosity of) mucus * Secretolytics – increase airway water or the volume of airway secretions * Mucokinetics – increase mucociliary transport (clearance) and transportability of mucus by cough * Mucoregulators – suppress underlying mechanisms of mucus hypersecretion Alternatively, attacking the affinity between secretions and the biological surfaces ...

Sweet Potato
The sweet potato or sweetpotato (''Ipomoea batatas'') is a dicotyledonous plant that belongs to the Convolvulus, bindweed or morning glory family (biology), family, Convolvulaceae. Its large, starchy, sweet-tasting tuberous roots are used as a root vegetable. The young shoots and leaves are sometimes eaten as Leaf vegetable, greens. Sweet potato cultivars, Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Sweet potato is only distantly related to the common potato (''Solanum tuberosum''), both being in the order Solanales. Although darker sweet potatoes are often referred to as "yams" in parts of North America, the species is not a yam (vegetable), true yam, which are monocots in the order Dioscoreales. Sweet potato is native to the tropical regions of the Americas. Of the approximately 50 Convolvulaceae#Genera, genera and more than 1,000 species of Convolvulaceae, ''I. batatas'' is the only crop plant of major importance—some o ...

Tuber
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. ''Stem tubers'' form thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots (''root tubers'') under the definition; these are found in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning "lump, bump, swelling". Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots., p. 124 Stem tubers A stem tuber forms from thickened rhizomes or stolons. The top sides of the tuber produce shoots that grow into typical stems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emmelina Monodactyla
''Emmelina monodactyla'' (T-moth or morning-glory plume moth) is a moth of the family Pterophoridae. It is found in Europe, Japan, central Asia, North Africa and North America. Description The wingspan is 18–27 mm. The moths fly nearly year-round. The moths are pale russet in colour, with a wingspan of 18–27 millimeters. The colouration is extremely variable, ranging from off-white with indistinct markings to a strong rust brown. The markings may vary considerably in size. The second and third segments are elongate. The caterpillars are greenish-yellow with a broad green band on the back, and a narrow broken yellow line running down the center. Some specimens may also have a wine-red marking on the back. The colour of the pupae may range from green to reddish brown, sometimes with black markings.. Biology The larvae mainly feed on Convolvulaceae species, including ''Calystegia sepium'', '' Calystegia spithamaea'', ''Calystegia soldanella'', ''Convolvulus arvensis'', ''Con ...

Bedellia Somnulentella
''Bedellia somnulentella'', the sweet potato leaf miner, is a moth in the family Bedelliidae. Description The wingspan is 8–10 mm. The larvae feed on '' Calystegia pubescens'', ''Calystegia sepium'', ''Convolvulus althaeoides'', ''Convolvulus arvensis'', ''Convolvulus siculus'', ''Convolvulus tricolour'', ''Ipomoea batatas'' and ''Ipomoea purpurea''. They mine the leaves of their host plant. The mine starts as a narrow tortuous corridor with a central frass line, that often cuts off part of the leaf. Later, larvae leave the mine and begin to make a series of full depth fleck mines. Pupation takes place outside the leaf. The pupa is attached to a leaf without a cocoon. Distribution Originally from Asia, where its food plants are found, it has reached a nearly cosmopolitan distribution and has been recorded from Russia, Ukraine, Georgia, southern Kazakhstan, Kirgizia, Uzbekistan, nearly all of Europe, the Middle East, Africa, India, Japan, North America, Australia, New Ze ...

Sweet Potato Leaf Beetle
Sweetness is a basic taste most commonly perceived when eating foods rich in sugars. Sweet tastes are generally regarded as pleasurable. In addition to sugars like sucrose, many other chemical compounds are sweet, including aldehydes, ketones, and sugar alcohols. Some are sweet at very low concentrations, allowing their use as non-caloric sugar substitutes. Such non-sugar sweeteners include saccharin and aspartame. Other compounds, such as miraculin, may alter perception of sweetness itself. The perceived intensity of sugars and high-potency sweeteners, such as Aspartame and Neohesperidin Dihydrochalcone, are heritable, with gene effect accounting for approximately 30% of the variation. The chemosensory basis for detecting sweetness, which varies between both individuals and species, has only begun to be understood since the late 20th century. One theoretical model of sweetness is the multipoint attachment theory, which involves multiple binding sites between a sweetness rece ...

Cassidinae
The Cassidinae (tortoise and leaf-mining beetles) are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra. Description The "cassidoids" have a rounded outline with the edges of the pronotum and elytra expanded, spreading out to cover the legs and head. They are often colourful and metallic, with ornate sculpturing; a few species have the ability to change the colour due to water movements within the translucent cuticle. All members of the subfamily have the mouthparts reduced into a cavity in the head capsule, the legs have four segmented tarsi. The hispoids have larvae that are leaf miners, while the cassidoids feed on the plant surfaces, sometimes covering their bodies with faecal shi ...
