Rivea Corymbosa
''Ipomoea corymbosa'' (''Rivea corymbosa'', ''Turbina corymbosa'') is a species of morning glory, native throughout Latin America from Mexico as far south as Peru and widely naturalised elsewhere. Its common names include Christmasvine, Christmaspops, and snakeplant. Description and names Known to natives of north and central Mexico by its Nahuatl name, coaxihuitl and by the south eastern natives as xtabentún (in Mayan), it is a perennial climbing vine with white flowers, often grown as an ornamental plant. Its flowers secrete copious amount of nectar, and the honey that bees make from it is very clear and aromatic. It also grows in Cuba, where it usually blooms from early December to February. It is considered one of the main honey plants of the island. This plant is often used for purposes other than recreation, as natives of Mexico consider the flour produced from its seeds (distinguished as ''ololiuhqui'' (''ololiúqui'', "round things")) a tool for divination and communi ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist 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 the son of a curate and was born in Råshult, in the countryside of Småland, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Evans Schultes
Richard Evans Schultes (''SHULL-tees'';Jonathan Kandell ''The New York Times'', April 13, 2001, Accessed April 26, 2020. January 12, 1915 – April 10, 2001) was an American biologist, considered to be the father of modern ethnobotany. He is known for his studies of the uses of plants by indigenous peoples, especially the indigenous peoples of the Americas. He worked on entheogenic or hallucinogenic plants, particularly in Mexico and the Amazon, involving lifelong collaborations with chemists. He had charismatic influence as an educator at Harvard University; several of his students and colleagues went on to write popular books and assume influential positions in museums, botanical gardens, and popular culture. His book ''The Plants of the Gods: Their Sacred, Healing, and Hallucinogenic Powers'' (1979), co-authored with chemist Albert Hofmann, the discoverer of LSD, is considered his greatest popular work: it has never been out of print and was revised into an expanded secon ...

Convolvulaceae
Convolvulaceae (), commonly called the bindweed, bindweeds or morning glory, morning glories, is a Family (biology), family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The Tuber, tubers of several species are edible, the best known of which is the sweet potato. Description Convolvulaceae can be recognized by their funnel-shaped, radially symmetrical corolla (flower), corolla; the floral formula for the family has five sepals, five fused petals, five epipetalous stamens (stamens fused to the petals), and a two-part syncarpous and superior gynoecium. The stems of these plants are usually winding, hence their Latin name (from ''convolvere'', "to wind"). The leaves are simple and alternate, without stipules. In parasitic Cuscuta (dodder) they are reduced to scales. The fruit can be a capsule, berry, or nut, all containing only two seeds per one locule (one ovule/ovary (botany), ovary). ...

5-HT2A Agonists
Serotonin (), also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter with a wide range of functions in both the central nervous system (CNS) and also peripheral tissues. It is involved in mood, cognition, reward, learning, memory, and physiological processes such as vomiting and vasoconstriction. In the CNS, serotonin regulates mood, appetite, and sleep. Most of the body's serotonin—about 90%—is synthesized in the gastrointestinal tract by enterochromaffin cells, where it regulates intestinal movements. It is also produced in smaller amounts in the brainstem's raphe nuclei, the skin's Merkel cells, pulmonary neuroendocrine cells, and taste receptor cells of the tongue. Once secreted, serotonin is taken up by platelets in the blood, which release it during clotting to promote vasoconstriction and platelet aggregation. Around 8% of the body's serotonin is stored in platelets, and 1–2% is found in the CNS. Serotonin acts as both a vasoconstrictor and v ...

Xtabay
''La Xtabay'' () is a Yucatec Maya folklore tale about a demonic femme fatale who preys upon men in the Yucatán Peninsula. She is said to dwell in the forest to lure men to their deaths with her incomparable beauty. She is described as having beautiful, shining black hair that falls down to her ankles and wearing a white dress. One of the most accepted versions of the myth comes from a book, ''Diez Leyendas Mayas'' (1998), written by Jesus Azcorra Alejos. Etymology The term "Xtab" was used to refer to an ancient Maya goddess Ixtab, the goddess of suicide by hanging or the gallows. According to ''Perez' Lexicon of the Maya Language'', "Ix" is the feminine prefix, and "tab", "taab", and "tabil" translate to "rope intended for some exclusive use." Ixtab was seen as a benevolent goddess who acted as a psychopomp to whoever hung themselves, leading them to paradise, as suicide was considered an honorable way of dying.

Invasive Species
An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MKULTRA
MKUltra was an illegal human experimentation program designed and undertaken by the U.S. Central Intelligence Agency (CIA) to develop procedures and identify drugs that could be used during interrogations to weaken individuals and force confessions through brainwashing and psychological torture. The term MKUltra is a CIA cryptonym: "MK" is an arbitrary prefix standing for the Office of Technical Service and "Ultra" is an arbitrary word out of a dictionary used to name this project. The program has been widely condemned as a violation of individual rights and an example of the CIA's abuse of power, with critics highlighting its disregard for consent and its corrosive impact on democratic principles. Project MKUltra began in 1953 and was halted in 1973. MKUltra used numerous methods to manipulate its subjects' mental states and brain functions, such as the covert administration of high doses of psychoactive drugs (especially LSD) and other chemicals without the subjects' c ...

Eleusinian Mysteries
The Eleusinian Mysteries () were initiations held every year for the Cult (religious practice), cult of Demeter and Persephone based at the Panhellenic Sanctuary of Eleusis in ancient Greece. They are considered the "most famous of the secret religious rites of ancient Greece". Their basis was a Bronze Age Agrarianism, agrarian cult, and there is some evidence that they were derived from the religious practices of the Mycenean Greece, Mycenean period.Dietrich (1975) ''The origins of Greek Religion''. Bristol Phoenix Press pp. 166, 167Walter Burkert. (1985)''Greek Religion''. Harvard University Press. p. 285 The Mysteries represented the myth of the Persephone#Abduction myth, abduction of Persephone from her mother Demeter by the king of the underworld Hades, in a cycle with three phases: the ''descent'' (loss), the ''search'', and the ''ascent'', with the main theme being the ''ascent'' () of Persephone and the reunion with her mother.

Kykeon
Kykeon (, ; from , ; "to stir, to mix") was an Ancient Greek drink of varied description. Some were made of water, barley and naturally occurring substances. Others were made with wine and grated cheese. It is widely believed that kykeon refers to a psychoactive brew, as in the case of the Eleusinian Mysteries. A kykeon was used at the climax of the Eleusinian Mysteries to break a sacred fast, but it is also mentioned as a favourite drink of Greek peasants. Ancient sources and description Kykeon is mentioned in Homeric texts: the Iliad describes it as consisting of Pramnian wine, barley, and grated goat's cheese. In the Odyssey, Circe adds some honey and pours her magic potion into it. In the Homeric Hymn to Demeter, the goddess refuses red wine but accepts kykeon made from water, barley, and pennyroyal. Pennyroyal, or mint, was supposed to have digestive properties: In Aristophanes' ''Peace'' Hermes recommends it to the hero who ate too much dry fruit and nuts. Pennyroyal ...

Claviceps Purpurea
''Claviceps purpurea'' is an ergot fungus that grows on the ear (botany), ears of rye and related cereal and forage plants. Consumption of Cereal, grains or seeds contaminated with the survival structure of this fungus, the ergot sclerotium, can cause ergotism in humans and other mammals. ''C. purpurea'' most commonly affects Open pollination, outcrossing species such as rye (its most common host), as well as triticale, wheat and barley. It affects oats only rarely. Life cycle An ''ergot kernel'' called ''Sclerotium clavus'' develops when a floret of flowering grass or cereal is infected by an ascospore of ''C. purpurea''. The infection process mimics a pollen grain growing into an ovary (plants), ovary during fertilization. Because infection requires access of the fungal spore to the Gynoecium, stigma, plants infected by ''C. purpurea'' are mainly outcrossing species with Anemophily, open flowers, such as rye (''Secale, Secale cereale'') and Alopecurus. The proliferating fun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alkaloid
Alkaloids are a broad class of natural product, naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. Alkaloids are produced by a large variety of organisms including bacteria, fungus, fungi, Medicinal plant, plants, and animals. They can be purified from crude extracts of these organisms by acid-base extraction, or solvent extractions followed by silica-gel column chromatography. Alkaloids have a wide range of pharmacology, pharmacological activities including antimalarial medication, antimalarial (e.g. quinine), asthma, antiasthma (e.g. ephedrine), chemotherapy, anticancer (e.g. omacetaxine mepesuccinate, homoharringtonine), cholinomimetic (e.g. galantamine), vasodilation, vasodilatory (e.g. vincamine), Antiarrhythmic agent, antiarrhythmic (e.g. quinidine), analgesic (e.g. morphine), antibacterial (e.g. chelerythrine), and anti-diabetic, antihyperglycemic activities (e.g. berb ...
