Ageratina Altissima
''Ageratina altissima'', also known as white snakeroot, richweed, or white sanicle, is a poisonous perennial herb in the family Asteraceae, native to eastern and central North America. An older binomial name for this species is ''Eupatorium rugosum'', but the genus ''Eupatorium'' has undergone taxonomic revision by botanists, and some species once included in it have been moved to other genera. Description Plants are upright or sometimes ascending, growing to tall, producing single or multi-stemmed clumps in mid to late summer and fall. Stems are smooth with opposite leaves spaced well apart, with each pair of leaves positioned at a 90-degree angle from the pair above and below (decussate). The upper part of the plant has multiple branches, which usually appear in opposite pairs. Leaves have sharply serrated margins and are up to long. At the end of the upper branches, flat-topped panicles or compound corymbs of white flower heads appear, measuring across. The flowers are a c ...

Carolus Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, 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 (biology), 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 ...

Tremetol
Tremetone is a chemical compound found in tremetol, a toxin mixture from snakeroot (''Ageratina altissima'') that causes milk sickness in humans and trembles in livestock. Tremetone is the main constituent of at least 11 chemically related substances in tremetol. Tremetone is toxic to fish, but not to chicken, and is therefore not the major toxic compound in tremetol. Tremetol can be found in a number of different species of the family Asteraceae, including snakeroot and rayless goldenrod (''Isocoma pluriflora''). Synthesis Tremetol, an oil with a straw-colored tinge, was first isolated from white snakeroot by J.F. Couch in 1929. Column chromatography of tremetol yielded a hydrocarbon, two steroids, and three ketones. Further isolation experiments revealed that tremetone is the major ketone constituent of the compound tremetol. Hence, tremetone was hypothesized to be responsible for the “trembles” that characterize the milk sickness disease. Tremetone was first synthesized ...

List Of Plants Poisonous To Equines
Many plants are poisonous to equines; the species vary depending on location, climate, and grazing conditions. In many cases, entire genera are poisonous to equines and include many species spread over several continents. Plants can cause reactions ranging from laminitis (found in horses bedded on shavings from black walnut trees), anemia, kidney disease and kidney failure (from eating the wilted leaves of red maples), to cyanide poisoning (from the ingestion of plant matter from members of the genus ''Prunus'') and other symptoms. Members of genus ''Prunus'' have also been theorized to be at fault for mare reproductive loss syndrome. Some plants, including yews, are deadly and extremely fast-acting. Several plants, including nightshade, become more toxic as they wilt and die, posing a danger to horses eating dried hay or plant matter blown into their pastures. The risk of animals becoming ill during the fall is increased, as many plants slow their growth in preparation for winte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Poisonous Plants
Plants that produce toxins are referred to as poisonous plants. Plants that cause irritation on contact are also described as "poisonous". The toxins in poisonous plants affect herbivores, and deter them from consuming the plants. Plants cannot move to escape their predators, so they must have other means of protecting themselves from herbivorous animals. Some plants have physical defenses such as thorns, spines and prickles, but by far the most common type of protection is chemical. Over millennia, through the process of natural selection, plants have evolved the means to produce a vast and complicated array of chemical compounds to deter herbivores. Tannin, for example, is a defensive compound that emerged relatively early in the evolutionary history of plants, while more complex molecules such as polyacetylenes are found in younger groups of plants such as the Asterales. Many of the known plant defense compounds primarily defend against consumption by insects, though other a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioscorides
Pedanius Dioscorides ( grc-gre, Πεδάνιος Διοσκουρίδης, ; 40–90 AD), “the father of pharmacognosy”, was a Greek physician, pharmacologist, botanist, and author of ''De materia medica'' (, On Medical Material) —a 5-volume Greek encyclopedia about herbal medicine and related medicinal substances (a pharmacopeia), that was widely read for more than 1,500 years. For almost two millennia Dioscorides was regarded as the most prominent writer on plants and plant drugs. Life A native of Anazarbus, Cilicia, Asia Minor, Dioscorides likely studied medicine nearby at the school in Tarsus, which had a pharmacological emphasis, and he dedicated his medical books to Laecanius Arius, a medical practitioner there. Though he writes he lived a "soldier's life" or "soldier-like life", his pharmacopeia refers almost solely to plants found in the Greek-speaking eastern Mediterranean, making it likely that he served in campaigns, or travelled in a civilian capacity, less w ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Shawnee
The Shawnee are an Algonquian-speaking indigenous people of the Northeastern Woodlands. In the 17th century they lived in Pennsylvania, and in the 18th century they were in Pennsylvania, Ohio, Indiana and Illinois, with some bands in Kentucky and Alabama. By the 19th century, they were forcibly removed to Missouri, Kansas, Texas, and ultimately Indian Territory, which became Oklahoma under the 1830 Indian Removal Act. Today, Shawnee people are enrolled in three federally recognized tribes, all headquartered in Oklahoma: the Absentee-Shawnee Tribe of Indians, Eastern Shawnee Tribe of Oklahoma, and Shawnee Tribe. Etymology Shawnee has also been written as Shaawanwaki, Ša·wano·ki, Shaawanowi lenaweeki, and Shawano. Algonquian languages have words similar to the archaic ''shawano'' (now: ''shaawanwa'') meaning "south". However, the stem ''šawa-'' does not mean "south" in Shawnee, but "moderate, warm (of weather)": See Charles F. Voegelin, "šawa (plus -ni, -te) MODERATE, WARM ...

Anna Pierce Hobbs Bixby
Anna Pierce Hobbs Bixby, sometimes spelled Bigsby, born Anna Pierce ( – c. 1870), was a midwife, frontier doctor, dentist, herbologist, and scientist in southern Illinois. Bixby discovered that white snakeroot (''Ageratina altissima'') contains a toxin. When cattle consume the plant, their meat and milk become contaminated and cause the sometimes fatal condition milk sickness. One of the most notable and tragic cases of the "milk sickness" was that of Nancy Hanks Lincoln, the mother of Abraham Lincoln, who died at 34 years old in 1818. Early life Bixby was the daughter of farmers, who had moved from Philadelphia and in 1828 settled in southeastern Illinois, close to what would become the village of Rock Creek. After finishing school, she traveled to Philadelphia to train in midwifery and dentistry, but on her return to Illinois she became the first physician in Hardin County and consequently, a general practitioner for her community. Bixby may also have been the first fem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abraham Lincoln
Abraham Lincoln ( ; February 12, 1809 – April 15, 1865) was an American lawyer, politician, and statesman who served as the 16th president of the United States from 1861 until his assassination in 1865. Lincoln led the nation through the American Civil War and succeeded in preserving the Union, abolishing slavery, bolstering the federal government, and modernizing the U.S. economy. Lincoln was born into poverty in a log cabin in Kentucky and was raised on the frontier, primarily in Indiana. He was self-educated and became a lawyer, Whig Party leader, Illinois state legislator, and U.S. Congressman from Illinois. In 1849, he returned to his successful law practice in central Illinois. In 1854, he was angered by the Kansas–Nebraska Act, which opened the territories to slavery, and he re-entered politics. He soon became a leader of the new Republican Party. He reached a national audience in the 1858 Senate campaign debates against Stephen A. Douglas. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nancy Hanks Lincoln
Nancy Hanks Lincoln (February 5, 1784 – October 5, 1818) was the mother of U.S. President Abraham Lincoln. Her marriage to Thomas Lincoln also produced a daughter, Sarah, and a son, Thomas Jr. When Nancy and Thomas had been married for just over 10 years, the family moved from Kentucky to western Perry County, Indiana, in 1816. When Spencer County was formed in 1818, the Lincoln Homestead lay within its current boundaries. Nancy Lincoln died from milk sickness or consumption in 1818 at the Little Pigeon Creek Community in Spencer County when Abraham was nine years old. Biography This article reflects the prevailing theories regarding Nancy Hanks Lincoln's heritage. There is information, however, published about the Shipley and Berry family and for Kentucky heritage sites that differs from the prevailing theory.

Upland South
The Upland South and Upper South are two overlapping cultural and geographic subregions in the inland part of the Southern and lower Midwestern United States. They differ from the Deep South and Atlantic coastal plain by terrain, history, economics, demographics, and settlement patterns. The term Upper South is a geographic term: the Southern states that are geographically north of the Lower or Deep South: primarily Virginia, West Virginia, Kentucky, North Carolina, and Tennessee, and to a lesser extent the District of Columbia and Maryland. The Upland South is defined by elevation above sea level; it is west of the population centers on the east coast. It has its own history and culture. It includes most of West Virginia and Kentucky, and parts of Virginia, Tennessee, North Carolina, Arkansas, Missouri, and Oklahoma. Upland South outposts were settled along the shores of the Ohio River. Geography There is a slight difference in usage between the two terms "Upland South" and ...
