Calea ternifolia (syn. Calea zacatechichi) [1] is a species of flowering plant in the aster family, Asteraceae. It is native to Mexico and Central America. [1] Its English language common names include bitter-grass, Mexican calea, [1] and dream herb. [2]
It is used in traditional medicine and ritual in its native range. [3]
In Mexico the plant is used as a herbal remedy for dysentery and fever. [3] The Zoque Popoluca people call the plant tam huñi ("bitter gum") and use it to treat diarrhea and asthma, and the Mixe people know it as poop taam ujts ("white bitter herb") and use it for stomachache and fever. [4]
The Chontal people of Oaxaca reportedly use the plant, known locally as thle-pela-kano, during divination. Isolated reports describe rituals that involve smoking a plant believed to be this species, drinking it as a tea, and placing it under a pillow to induce divinatory or lucid dreams due to its properties as an oneirogen. [5] Zacatechichi, the former species name, is a Hispanicized form of the Nahuatl word "zacatl chichic" meaning "bitter grass". [6] Users take the plant to help them remember their dreams; [2] [7] known side effects include nausea and vomiting related to the taste and mild-to-severe allergic reaction.
While quite bitter if brewed in hot water, the bitterness can be considerably masked by brewing with Osmanthus flowers, which have a compatible scent profile.
Chemical compounds isolated from this species include flavones [8] such as acacetin [9] and sesquiterpene lactones such as germacranolides. [10] The compound that is thought to cause the effects of Calea ternifolia is Caleicine a Prodrug of Eugenol a potent GABA positive modulator. [11]
Calea ternifolia and it's effects are not fully understood beyond GABA modulation from Caleicine and other GABAergic compounds. The plant is known to potentiate dreams and hypnotic states and is bioavailable through common routes of administration such as smoking and oral.
Many compounds have been isolated from the plant and suspected to cause the psychoactive effects. Notable compounds that have been isolated are: [11]
It is thought these compounds, and their respective pharmacological classes create the effects of Calea ternifolia.
Caleicine is a unique sesquiterpene compound found only in Calea ternifolia [11] and is one of many GABAergic compounds found in the plant and acts as a prodrug to the known bioactive and potent Eugenol. Caleicine is a strong candidate to be responsible the effects of Calea ternifolia as the GABA modulation Eugenol exhibits are the same that of Calea ternifolia. [15] [16]
Calea ternifolias negative side effects, nausea, vomiting and delirium based hallucinations, [17] are the same that of Eugenol [16] and other GABAergic compounds.
GABA positive allosteric site modulation is found in many sedative substances such as Methaqualone, Propofol, Alcohol (Ethanol) and Zolpidem. The properties of GABA positive modulating substances typically are anxiolytic, anticonvulsant, oneirogenic, sedative, hypnotic, euphoriant, and muscle relaxant effects.
In a study, 12 participants were given extracts of Calea ternifolia and experienced effects of mild augmentation of sensorial perceptions, imaginings, thought gaps, and retrieval problems; lethargy and a short sleep with vivid dreams. [15]
While it is not a controlled substance under federal law in the United States, some states have considered it individually. Louisiana State Act 159 specifies that it is illegal to possess if it is intended for human consumption, but not if they are intended for ornamental or landscaping use. Tennessee proposed a bill that would have made this and many other plants classified as hallucinogenic illegal, but when the bill was passed only Salvia divinorum was banned. [18]
This plant was banned in Poland in March 2009. [2] [19]
Under the Psychoactive Substances Act 2016 in the United Kingdom, Calea is technically illegal, however as the mechanisms are not well understood, it cannot be classed as a CNS stimulant or Depressant and therefor is legal.
One study suggest that the herb may have some toxic properties towards kidneys (nephrotoxicity). [20] This is likely due to the Caleicine in the plant being metabolised into the nephrotoxic compound Eugenol that can cause liver toxicity in high doses. [16]
American composer David Woodard, who cultivated Calea ternifolia on his San Francisco estate, composed a motet entitled "Calea Zacatechichi", which he recorded with a Hispanic choir. [21] : 34
Herbal teas, technically known as herbal infusions, and less commonly called tisanes, are beverages made from the infusion or decoction of herbs, spices, or other plant material in hot water. Often herb tea, or the plain term tea, is used as a reference to all sorts of herbal teas. Many herbs used in teas/tisanes are also used in herbal medicine and in folk medicine.
Mescaline, also known as mescalin or mezcalin, as well as 3,4,5-trimethoxyphenethylamine, is a naturally occurring psychedelic protoalkaloid of the substituted phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin. It binds to and activates certain serotonin receptors in the brain, producing hallucinogenic effects.
Thujone is a ketone and a monoterpene that occurs predominantly in two diastereomeric (epimeric) forms: (−)-α-thujone and (+)-β-thujone.
Ergine, also known as d-lysergic acid amide (LSA) and d-lysergamide, is an ergoline alkaloid that occurs in various species of vines of the Convolvulaceae and some species of fungi. The psychedelic properties in the seeds of ololiuhqui, Hawaiian baby woodrose and morning glories have been linked to ergine and/or isoergine, its epimer, as it is an alkaloid present in the seeds.
Muscimol is one of the principal psychoactive constituents of Amanita muscaria and related species of mushroom. Muscimol is a potent and selective orthosteric agonist for the GABAA receptor and displays sedative-hypnotic, depressant and hallucinogenic psychoactivity. This colorless or white solid is classified as an isoxazole.
Aniracetam, also known as N-anisoyl-2-pyrrolidinone, is a racetam which is sold in Europe as a prescription drug. It is not approved by the Food and Drug Administration for use in the United States as a prescription medication or dietary supplement. Despite the FDA's lack of approval, the drug is readily available over-the-counter in misbranded dietary supplements.
Eugenol is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove, nutmeg, cinnamon, basil and bay leaf. It is present in concentrations of 80–90% in clove bud oil and at 82–88% in clove leaf oil. Eugenol has a pleasant, spicy, clove-like scent. The name is derived from Eugenia caryophyllata, the former Linnean nomenclature term for cloves. The currently accepted name is Syzygium aromaticum.
The GABAA receptor (GABAAR) is an ionotropic receptor and ligand-gated ion channel. Its endogenous ligand is γ-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system. Accurate regulation of GABAergic transmission through appropriate developmental processes, specificity to neural cell types, and responsiveness to activity is crucial for the proper functioning of nearly all aspects of the central nervous system (CNS). Upon opening, the GABAA receptor on the postsynaptic cell is selectively permeable to chloride ions and, to a lesser extent, bicarbonate ions.
An oneirogen, from the Greek ὄνειρος óneiros meaning "dream" and gen "to create", is a substance or other stimulus which produces or enhances dreamlike states of consciousness. This is characterized by an immersive dream state similar to REM sleep, which can range from realistic to alien or abstract.
In molecular biology and physiology, something is GABAergic or GABAnergic if it pertains to or affects the neurotransmitter gamma-aminobutyric acid (GABA). For example, a synapse is GABAergic if it uses GABA as its neurotransmitter, and a GABAergic neuron produces GABA. A substance is GABAergic if it produces its effects via interactions with the GABA system, such as by stimulating or blocking neurotransmission.
Psilacetin, also known as O-acetylpsilocin or as 4-acetoxy-N,N-dimethyltryptamine, is a semi-synthetic serotonergic psychedelic drug that has been suggested by David Nichols to be a potentially useful alternative to psilocybin for pharmacological studies, as they are both believed to be prodrugs of psilocin. However, some users report that O-acetylpsilocin's subjective effects differ from those of psilocybin and psilocin. Additionally, some users prefer 4-AcO-DMT to natural psilocybin mushrooms due to feeling fewer adverse side effects such as nausea and heavy body load, which are more frequently reported in experiences involving natural mushrooms. It is the acetylated form of the psilocybin mushroom alkaloid psilocin and is a lower homolog of 4-AcO-MET, 4-AcO-DET, 4-AcO-MiPT and 4-AcO-DiPT.
Silene undulata is a plant native to the Eastern Cape of South Africa.
A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. Consumption of drugs can be via inhalation, injection, smoking, ingestion, absorption via a patch on the skin, suppository, or dissolution under the tongue.
A GABA receptor agonist is a drug that is an agonist for one or more of the GABA receptors, producing typically sedative effects, and may also cause other effects such as anxiolytic, anticonvulsant, and muscle relaxant effects. There are three receptors of the gamma-aminobutyric acid. The two receptors GABA-α and GABA-ρ are ion channels that are permeable to chloride ions which reduces neuronal excitability. The GABA-β receptor belongs to the class of G-Protein coupled receptors that inhibit adenylyl cyclase, therefore leading to decreased cyclic adenosine monophosphate (cAMP). GABA-α and GABA-ρ receptors produce sedative and hypnotic effects and have anti-convulsion properties. GABA-β receptors also produce similar effects. Furthermore, they lead to changes in gene transcription, and are mainly found in autonomic nervous system centers.
Salvia divinorum is a species of plant in the sage genus Salvia, known for its transient psychoactive properties when its leaves, or extracts made from the leaves, are administered by smoking, chewing, or drinking. The leaves contain the potent compound salvinorin A and can induce a dissociative state and hallucinations.
3-Hydroxyphenazepam is a benzodiazepine with hypnotic, sedative, anxiolytic, and anticonvulsant properties. It is an active metabolite of phenazepam, as well as the active metabolite of the benzodiazepine prodrug cinazepam. Relative to phenazepam, 3-hydroxyphenazepam has diminished myorelaxant properties, but is about equivalent in most other regards. Like other benzodiazepines, 3-hydroxyphenazepam behaves as a positive allosteric modulator of the benzodiazepine site of the GABAA receptor with an EC50 value of 10.3 nM. It has been sold as a designer drug.
Caleicine is a unique sesquiterpene compound found exclusively in Calea ternifolia, a Mexican flowering plant known for its potential psychoactive properties. This compound has garnered interest in the field of ethnopharmacology and natural product chemistry due to its putative role as a prodrug of eugenol, a potent GABA positive modulator.
