Acorus americanus

Acorus americanus, the American sweet flag, is an emergent wetland plant native to the northern United States and Canada. This perennial plant has bright green blade-shaped leaves that arise directly from the rhizomes and sheath into each other at the base. Additionally the blades have 2-6 raised veins, and a swollen center when viewed in cross section. The foliage has a citrus-like spicy aromatic quality, and can be used to flavor beer. It is a flowering plant with inconspicuous flowers that are arranged on a lateral spadix (a thickened, fleshy axis) and the fertilized flowers produce berries with a jelly inside. This plant is protected as a state endangered species in Pennsylvania. [1]

Etymology

The name "Acorus" is derived from the Greek word 'acoron', a name used by Dioscorides, which in turn was derived from 'coreon', meaning 'pupil', because it was used in herbal medicine as a treatment for inflammation of the eye.

The species name, "americanus" simply indicates that this is an American species of this genus, differentiating it from the very similar European and western Asian species Acorus calamus .

Taxonomy

Acorus americanus was formerly classified as Acorus calamus var. americanus. It differs only in being a fertile diploid (2n = 24)], whereas most of the A. calamus of Europe and Asia is a sterile triploid species, that only spreads asexually. Diploid plants in northern Asia may be representatives of A. americanus. [2] Also as a diploid it does not produce β-asarone.[ citation needed ]

Uses

This plant was used extensively by Native Americans and early European settlers.

Chemistry

In 1968 the Food and Drug Administration banned Acorus calamus from being used as a food additive and as a medicinal as a result of lab studies that involved supplementing the diets of lab animals over a prolonged period of time with massive doses of isolated chemicals (β-asarone) from the Indian Jammu strain of Acoruscalamus. The plant was labeled procarcinogenic. [3] [4] [5] [ unreliable source? ] Wichtl says "It is not clear whether the observed carcinogenic effects in rats are relevant to the human organism." [6] However, most sources advise caution in ingesting strains other than the diploid strain.

Like the diploid strains of Acorus calamus in parts of the Himalayas, Mongolia, and C Siberia, the Acorus americanus diploid strain does not contain the procarcinogenic β-asarone. [7] [8] [ verification needed ] [9] Research has consistently demonstrated that "β-asarone was not detectable in the North American spontaneous diploid Acorus [Calamus var. Americanus]". [10]

It is believed by some that calamus is a hallucinogen. This urban legend is based on two pages of a book written by Hoffer and Osmund entitled The Hallucinogens. The information on these two pages came from anecdotal reports from two individuals (a husband and wife) who reported that they had ingested calamus on a few occasions. [5] [11] None of the components in calamus are converted to TMA (trimethoxyamphetamine) in the human organism. [11] To date there is no solid evidence of any hallucinogenic substances in Acorus calamus.

However, for Native Americans, specifically the Alberta Cree, it has been reported that "the root {was} chewed for the hallucinogenic effects," [12] so perhaps more investigation is needed.

Calamus shows neuroprotective effect against stroke and chemically induced neurodegeneration in rats. Specifically, it has a protective effect against acrylamide induced neurotoxicity. [13]

In genetics, a mutagen is a physical or chemical agent that permanently changes genetic material, usually DNA, in an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer in animals, such mutagens can therefore be carcinogens, although not all necessarily are. All mutagens have characteristic mutational signatures with some chemicals becoming mutagenic through cellular processes.

Psilocybin is a naturally occurring psychedelic prodrug compound produced by more than 200 species of fungi. The most potent are members of genus Psilocybe, such as P. azurescens, P. semilanceata, and P. cyanescens, but psilocybin has also been isolated from about a dozen other genera. Psilocybin is itself biologically inactive but is quickly converted by the body to psilocin, which has mind-altering effects similar, in some aspects, to those of lysergic acid diethylamide (LSD), mescaline, and dimethyltryptamine (DMT). In general, the effects include euphoria, visual and mental hallucinations, changes in perception, distorted sense of time, and perceived spiritual experiences. It can also cause adverse reactions such as nausea and panic attacks.

Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH2=CHC(O)NH2. It is a white odorless solid, soluble in water and several organic solvents.

<i>Acorus</i> Genus of aquatic plants

Acorus is a genus of monocot flowering plants. This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots. Some older studies indicated that it was placed in a lineage, that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots. However, modern phylogenetic studies demonstrate that Acorus is sister to all other monocots. Common names include calamus and sweet flag.

β-Carboline Chemical compound also known as norharmane

β-Carboline (9H-pyrido[3,4-b]indole) represents the basic chemical structure for more than one hundred alkaloids and synthetic compounds. The effects of these substances depend on their respective substituent. Natural β-carbolines primarily influence brain functions but can also exhibit antioxidant effects. Synthetically designed β-carboline derivatives have recently been shown to have neuroprotective, cognitive enhancing and anti-cancer properties.

Harmine is a beta-carboline and a harmala alkaloid. It occurs in a number of different plants, most notably the Syrian rue and Banisteriopsis caapi. Harmine reversibly inhibits monoamine oxidase A (MAO-A), an enzyme which breaks down monoamines, making it a Reversible inhibitor of monoamine oxidase A (RIMA). Harmine does not inhibit MAO-B. Harmine is also known as banisterin, banisterine, telopathin, telepathine, leucoharmine and yagin, yageine.

<span class="mw-page-title-main">Deliriant</span> Class of psychoactive drugs

Deliriants are a subclass of hallucinogen. The term was coined in the early 1980s to distinguish these drugs from psychedelics such as LSD and dissociatives such as ketamine, due to their primary effect of causing delirium, as opposed to the more lucid and less disturbed states produced by other types of hallucinogens. The term generally refers to anticholinergic drugs, which are substances that inhibit the function of the neurotransmitter acetylcholine. Common examples of deliriants include plants of the genera Datura and Brugmansia as well as higher than recommended dosages of diphenhydramine (Benadryl). A number of plant deliriants such as that of the Solanaceae family, particularly in the Americas have been used by some indigenous cultures to reach delirious and altered states for traditions or rituals, such as rites of passage, divination or communicating with the ancestors. Despite their long history of use, deliriants are the least-studied class of hallucinogens in terms of their behavioral and neurological effects.

<span class="mw-page-title-main">Heterocyclic amine</span> Any heterocyclic compound having at least one nitrogen heteroatom

Heterocyclic amines, also sometimes referred to as HCAs, are chemical compounds containing at least one heterocyclic ring, which by definition has atoms of at least two different elements, as well as at least one amine (nitrogen-containing) group. Typically it is a nitrogen atom of an amine group that also makes the ring heterocyclic, though compounds exist in which this is not the case. The biological functions of heterocyclic amines vary, including vitamins and carcinogens. Carcinogenic heterocyclic amines are created by high temperature cooking of meat and smoking of plant matter like tobacco. Some well known heterocyclic amines are niacin, nicotine, and the nucleobases that encode genetic information in DNA.

<span class="mw-page-title-main">Head-twitch response</span>

The head-twitch response (HTR) is a rapid side-to-side head movement that occurs in mice and rats after the serotonin 5-HT2A receptor is activated. The prefrontal cortex may be the neuroanatomical locus mediating the HTR. Many serotonergic hallucinogens, including lysergic acid diethylamide (LSD), induce the head-twitch response, and so the HTR is used as a behavioral model of hallucinogen effects. However while there is generally a good correlation between compounds that induce head twitch in mice and compounds that are hallucinogenic in humans, it is unclear whether the head twitch response is primarily caused by 5-HT2A receptors, 5-HT2C receptors or both, though recent evidence shows that the HTR is mediated by the 5-HT2A receptor and modulated by the 5-HT2C receptor. Also, the effect can be non-specific, with head twitch responses also produced by some drugs that do not act through 5-HT2 receptors, such as phencyclidine, yohimbine, atropine and cannabinoid receptor antagonists. As well, compounds such as 5-HTP, fenfluramine, 1-Methylpsilocin, Ergometrine, and 3,4-di-methoxyphenethylamine (DMPEA) can also produce head twitch and do stimulate serotonin receptors, but are not hallucinogenic in humans. This means that while the head twitch response can be a useful indicator as to whether a compound is likely to display hallucinogenic activity in humans, the induction of a head twitch response does not necessarily mean that a compound will be hallucinogenic, and caution should be exercised when interpreting such results.

The consumption of hallucinogenic plants as entheogens goes back to thousands of years. Psychoactive plants contain hallucinogenic particles that provoke an altered state of consciousness, which are known to have been used during spiritual rituals among cultures such as the Aztec, the Maya, and Inca. The Maya were indigenous people of Mexico and Central America that had significant access to hallucinogenic substances. Archaeological, ethnohistorical, and ethnographic data show that Mesoamerican cultures used psychedelic substances in therapeutic and religious rituals. The consumption of many of these substances dates back to the Olmec era ; however, Mayan religious texts reveal more information about the Aztecs and Mayan civilization. These substances are considered entheogens because they were used to communicate with divine powers. "Entheogen," an alternative term for hallucinogen or psychedelic drug, derived from ancient Greek words ἔνθεος and γενέσθαι. This neologism was coined in 1979 by a group of ethnobotanists and scholars of mythology. Some authors claim entheogens have been used by shamans throughout history, with appearances in prehistoric cave art such as a cave painting at Tassili n'Ajjer, Algeria that dates to roughly 8000 BP. Shamans in Mesoamerica served to diagnose the cause of illness by seeking wisdom through a transformational experience by consuming drugs to learn the crisis of the illness
