''Salvia divinorum'' (Latin: "sage of the diviners"; also called ska maría pastora, seer's sage, yerba de la pastora, magic mint or simply salvia) is a plant species with transient psychoactive properties when its leaves are consumed by chewing, smoking, or as a tea. The leaves contain opioid-like compounds that induce hallucinations. Because the plant has not been well-studied in high-quality clinical research, little is known about its toxicology, adverse effects, or safety over long-term consumption. Its native habitat is cloud forest in the isolated Sierra Mazateca of Oaxaca, Mexico, where it grows in shady, moist locations. Valdes 1987, p. 106. The plant grows to over a meter high, has hollow square stems like others in the mint family Lamiaceae, large leaves, and occasional white flowers with violet calyxes. Botanists have not determined whether ''Salvia divinorum'' is a cultigen or a hybrid because native plants reproduce vegetatively and rarely produce viable see ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ...

Agonist
An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what it is currently doing. In contrast, an antagonist blocks the action of the agonist, while an inverse agonist causes an action opposite to that of the agonist. Etymology From the Greek αγωνιστής (agōnistēs), contestant; champion; rival < αγων (agōn), contest, combat; exertion, struggle < αγω (agō), I lead, lead towards, conduct; drive

Types of agonists

can be activated by either endogenous agonists (such as

Kappa Opioid Receptor
Kappa (uppercase Κ, lowercase κ or cursive ; el, κάππα, ''káppa'') is the 10th letter of the Greek alphabet, representing the voiceless velar plosive sound in Ancient and Modern Greek. In the system of Greek numerals, has a value of 20. It was derived from the Phoenician letter kaph . Letters that arose from kappa include the Roman K and Cyrillic К. The uppercase form is identical to the Latin K. Greek proper names and placenames containing kappa are often written in English with "c" due to the Romans' transliterations into the Latin alphabet: Constantinople, Corinth, Crete. All formal modern romanizations of Greek now use the letter "k", however. The cursive form is generally a simple font variant of lower-case kappa, but it is encoded separately in Unicode for occasions where it is used as a separate symbol in math and science. In mathematics, the kappa curve is named after this letter; the tangents of this curve were first calculated by Isaac Barrow in ...

Salvinorin A
Salvinorin A is the main active psychotropic molecule in '' Salvia divinorum''. Salvinorin A is considered a dissociative hallucinogen. It is structurally distinct from other naturally occurring hallucinogens (such as DMT, psilocybin, and mescaline) because it contains no nitrogen atoms; hence, it is not an alkaloid (and cannot be rendered as a salt), but rather is a terpenoid. It also differs in subjective experience, compared to other hallucinogens, and has been described as dissociative. Salvinorin A can produce psychoactive experiences in humans with a typical duration of action being several minutes to an hour or so, depending on the method of ingestion. Salvinorin A is found with several other structurally related salvinorins. Salvinorin is a ''trans''-neoclerodane diterpenoid. It acts as a kappa opioid receptor agonist and is the first known compound acting on this receptor that is not an alkaloid. History Salvinorin A was first described and named in 1982 ...

Diterpenoid
Diterpenes are a class of chemical compounds composed of four isoprene units, often with the molecular formula C20H32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway, with geranylgeranyl pyrophosphate being a primary intermediate. Diterpenes form the basis for biologically important compounds such as retinol, retinal, and phytol. They are known to be antimicrobial and antiinflammatory. Structures As with most terpenes a huge number of potential structures exists, which may be broadly divided according to the number of rings present. Biosynthesis Diterpenes are derived from the addition of one IPP unit to FPP to form geranylgeranyl-pyrophosphate (GGPP). From GGPP, structural diversity is achieved mainly by two classes of enzymes; the diterpene synthases and cytochromes P450. Several diterpenes are produced by plants and cyanobacteria. GGPP is also the precursor for the synthesis of the phytane by the action of the enzyme geranylger ...

Psychoactive Drug
A psychoactive drug, psychopharmaceutical, psychoactive agent or psychotropic drug is a chemical substance, that changes functions of the nervous system, and results in alterations in perception, mood, consciousness, cognition or behavior. These substances may be used medically, recreationally or spiritually to a. Purposefully improve one’s perceived performance b. Alter one's consciousness (such as with entheogens for ritual, spiritual or shamanic purposes) or c. For research. Some categories of psychoactive drugs - which are believed, by some, to have therapeutic value - may be prescribed by some physicians and other healthcare practitioners. Examples of medication categories that may contain potentially beneficial psychoactive drugs include, but are not limited to: # Anesthetics # Analgesics # Anticonvulsants # Anti-Parkinson’s medications # Medications used to treat Neuropsychiatric Disorders a. Antidepressants b. Anxiolytics c. Antipsychotics ...

Altered State Of Consciousness
An altered state of consciousness (ASC), also called altered state of mind or mind alteration, is any condition which is significantly different from a normal waking state. By 1892, the expression was in use in relation to hypnosis, though there is an ongoing debate as to whether hypnosis is to be identified as an ASC according to its modern definition. The next retrievable instance, by Dr Max Mailhouse from his 1904 presentation to conference, however, is unequivocally identified as such, as it was in relation to epilepsy, and is still used today. In academia, the expression was used as early as 1966 by Arnold M. Ludwig and brought into common usage from 1969 by Charles Tart. It describes induced changes in one's mental state, almost always temporary. A synonymous phrase is "altered state of awareness". Definitions There is no general definition of an altered state of consciousness, as any definitional attempt would first have to rely on a definition of a normal state of consci ...

Mazatec Shamans
The Mazatec Shamans are known for their ritual use of psilocybin mushrooms, psychoactive morning glory seeds, and ''Salvia divinorum''. María Sabina was one of the best known of the Mazatec Shamans. Her healing psilocybin mushroom ceremonies, called '' veladas'', contributed to the popularization of indigenous Mexican ritual use of entheogenic mushrooms among westerners The Western world, also known as the West, primarily refers to the various nations and states in the regions of Europe, North America, and Oceania.
