Phalaris Brachystachys
''Phalaris brachystachys'', the confused canary-grass or shortspike canarygrass, is an annual grass with growth habits and cultural requirements similar to ''Phalaris aquatica''. It is native to the Mediterranean region. It grows most actively during the spring and fall, while resting during the heat of midsummer and the short cool days of winter. It also must be protected from heavy freezes. Some ''Phalaris'' species contain gramine, which can cause brain damage, other organ damage, central nervous system damage and death in sheep. While at least one strain showed an extremely strong occurrence of N,N-DMT as the sole alkaloid, other strains indicated the presence of 5-MeO-DMT as well. Strongly positive human bioassays have been reported using some clones.

Johann Heinrich Friedrich Link
Johann Heinrich Friedrich Link (2 February 1767 – 1 January 1851) was a German naturalist and botanist. Biography Link was born at Hildesheim as a son of the minister August Heinrich Link (1738–1783), who taught him love of nature through collection of 'natural objects'. He studied medicine and natural sciences at the Hannoverschen Landesuniversität of Göttingen, and graduated as MD in 1789, promoting on his thesis ''"Flora der Felsgesteine rund um Göttingen"'' (Flora of the rocky beds around Göttingen). One of his teachers was the famous natural scientist Johann Friedrich Blumenbach (1752–1840). He became a private tutor (''Privatdozent'') in Göttingen. In 1792 he became the first professor of the new department of chemistry, zoology and botany at the University of Rostock. During his stay at Rostock, he became an early follower of the antiphlogistic theory of Lavoisier, teaching about the existence of oxygen instead of phlogiston. He was also a proponent of the ...

Phalaris Aquatica
''Phalaris aquatica'', known by the common names bulbous canary-grass and Harding grass, is a species of grass in the genus ''Phalaris'' of the family Poaceae. Description It is an erect, waist-high, stout perennial bunch grass, with grayish to bluish green leaves. Flowering heads are dense, spike-like, and usually long. It is slow to develop from seed, but can form large bunches after several years. ''Phalaris arundinacea'' (reed canary grass) differs from Harding grass in having more distinct rhizomes, and an inflorescence that is compact at first but becomes more open as the branches spread. Hybrids of Harding grass and reed canary grass have been produced. Varieties include 'AQ1', 'Uneta', and 'Australis'. ''P. aquatica'' is a quick-growing grass which incorporates and utilises soil nitrogen rapidly. Geography ''Phalaris aquatica'' originated from Southern Europe and the Caucasus. It is naturalized in South Africa, Australia, New Zealand and the USA. Although very recent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gramine
Gramine (also called donaxine) is a naturally occurring indole alkaloid present in several plant species. Gramine may play a defensive role in these plants, since it is toxic to many organisms. Occurrence Gramine has been found in the giant reed, ''Arundo donax'', ''Acer saccharinum'' (Silver Maple), ''Hordeum'', (a grass genus that includes barley) and ''Phalaris'' (another grass genus). Effects and toxicity Gramine has been found to act as an agonist of the adiponectin receptor 1 Adiponectin receptor 1 (AdipoR1) is a protein which in humans is encoded by the ''ADIPOR1'' gene. It is a member of the progestin and adipoQ receptor (PAQR) family, and is also known as PAQR1. Structure Similar to G protein-coupled receptors (GP ... (AdipoR1). The LD50 of gramine is 44.6 mg/ kg iv in mice and 62.9 mg/ kg iv in rats. Numerous studies have been done on the toxicity in insects harmful to crops for use as a possible insecticide.

Central Nervous System
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts. It is a structure composed of nervous tissue positioned along the rostral (nose end) to caudal (tail end) axis of the body and may have an enlarged section at the rostral end which is a brain. Only arthropods, cephalopods and vertebrates have a true brain (precursor structures exist in onychophorans, gastropods and lancelets). The rest of this article exclusively discusses the vertebrate central nervous system, which is radically distinct from all other animals. Overview In vertebrates, the brain and spinal cord are both enclosed in the meninges. The meninges provide a barrier to chemicals dissolv ...

N,N-DMT
''N'',''N''-Dimethyltryptamine (DMT or ''N'',''N''-DMT, SPL026) is a substituted tryptamine that occurs in many plants and animals, including human beings, and which is both a derivative and a structural analog of tryptamine. It is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen. DMT has a rapid onset, intense effects, and a relatively short duration of action. For those reasons, DMT was known as the "business trip" during the 1960s in the United States, as a user could access the full depth of a psychedelic experience in considerably less time than with other substances such as LSD or psilocybin mushrooms. DMT can be inhaled, ingested, or injected and its effects depend on the dose, as well as the mode of administration. When inhaled or injected, the effects last a short period of time: about five to 15 minutes. Effects can last three hours or more when orally ingested along with a monoamine oxidase inhibitor (MAOI), suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5-MeO-DMT
5-MeO-DMT (5-methoxy-''N'',''N''-dimethyltryptamine) or O-methyl-bufotenin is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and also is secreted by the glands of at least one toad species, the Colorado River toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. Slang terms include Five-methoxy, The power, and Toad venom. Chemistry 5-MeO-DMT was first synthesized in 1936, and in 1959 it was isolated as one of the psychoactive ingredients of '' Anadenanthera peregrina'' seeds used in preparing Yopo snuff. It was once believed to be a major component of the psychoactive effects of the snuff, although this has recently been shown to be unlikely, due to the limited or sometimes even non-existent quantity contained within the seeds, which instead achieve their psychoactivity from the ''O''-demethylated metabolite of 5-MeO-DMT, bufotenin. It is metabolized mainly by CYP2D6. Effects D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalaris (plant)
''Phalaris'' is a genus of grasses. Various species of ''Phalaris'' grow on every continent except Antarctica. They can be found in a broad range of habitats from below sea level to thousands of feet above sea level and from wet marshy areas to dry places. ''P. arundinacea'' and ''P. aquatica'' are sometimes invasive species in wetlands. Alkaloids Some ''Phalaris'' species contain gramine, which, in sheep and to a lesser extent in cattle, is toxic and can cause brain damage, other organ damage, central nervous system damage, and death. ''Phalaris arundinacea'', ''Phalaris aquatica'', and '' Phalaris brachystachys'' are known to contain the alkaloids DMT, 5-MeO-DMT, and 5-OH-DMT (bufotenin). Some research has been done into the variability of alkaloids in the ''Phalaris'' grasses. Strains with high levels of alkaloids are best avoided in locations with grazing cattle and sheep, due to potential toxicity. Such high-alkaloid strains include ''Phalaris aquatica AQ-1'' and the spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Western Asia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Lebanon
The flora of Lebanon includes approximately 2,600 plant species. Situated on the eastern coast of the Mediterranean Basin, Lebanon is a reservoir of plant diversity and one of the world's biodiversity hotspots for conservation priorities. Endemic species constitute 12% of the Lebanese flora; 221 plant species are broad endemics and 90 are narrow endemics.. Important Plant Areas (IPAs) featuring the country exceptional botanical richness were defined in 2018. The natural vegetation of Lebanon has been threatened by overexploitation and fragmentation as a result of urban expansion, overgrazing, tourism and the impact of warfare. The cedar of Lebanon is the national symbol of the country; growing in the Lebanon Mountain range, these trees have been heavily harvested over the years for their valuable timber and few mature trees still remain. Nevertheless, Lebanon is more heavily wooded than most other countries in the region and pine, oak, fir, beech, cypress and juniper are to be f ...
