Context: Dissociatives are a class of hallucinogen, which distort perceptions of sight and sound and produce feelings of detachment  dissociation  from the environment and self. This is done through reducing or blocking signals to the conscious mind from other parts of the brain. Although many kinds of drugs are capable of such action, dissociatives are unique in that they do so in such a way that they produce hallucinogenic effects, which may include sensory deprivation, dissociation, hallucinations, and dream-like states or trances. Some, which are nonselective in action and affect the dopamine and/or opioid systems, may be capable of inducing euphoria. Many dissociatives have general depressant effects and can produce sedation, respiratory depression, analgesia, anesthesia, and ataxia, as well as cognitive and memory impairment and amnesia., Salvia divinorum (also known as sage of the diviners, ska maría pastora, seer's sage, yerba de la pastora and just salvia) is a psychoactive plant which can induce visions and other altered and spiritual experiences. Its native habitat is in cloud forest in the isolated Sierra Mazateca of Oaxaca, Mexico, where it grows in shady and moist locations. The plant grows to over a meter high, has hollow square stems, large leaves, and occasional white flowers with violet calyxes. Botanists have not determined whether "Salvia divinorum" is a cultigen or a hybrid; native plants reproduce vegetatively, rarely producing viable seed., Salvinorin A is the main active psychotropic molecule in "Salvia divinorum", a Mexican plant which has a long history of use as an entheogen by indigenous Mazatec shamans. Salvinorin A is considered a dissociative., Mexico (, modern Nahuatl ), officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost two million square kilometers (over 760,000 sq mi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America. Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León., A cloud forest, also called a fog forest, is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the saddles of mountains, where moisture introduced by settling clouds is more effectively retained., A cultigen (from the Latin "cultus"  cultivated, and "gens"  kind) is a plant that has been deliberately altered or selected by humans; it is the result of artificial selection. These "man-made" or anthropogenic plants are, for the most part, plants of commerce that are used in horticulture, agriculture and forestry. Because cultigens are defined by their mode of origin and not by where they are growing, plants meeting this definition remain cultigens whether they are naturalised in the wild, deliberately planted in the wild, or growing in cultivation.
Cultigens arise in the following ways: selections of variants from the wild or cultivation including vegetative sports (aberrant growth that can be reproduced reliably in cultivation); plants that are the result of plant breeding and selection programs; genetically modified plants (plants modified by the deliberate implantation of genetic material); and graft-chimaeras (plants grafted to produce mixed tissue, the graft material possibly from wild plants, special selections, or hybrids)., An entheogen, meaning "generating the divine within" is any chemical substance used in a mystical, religious, shamanic, or spiritual context with the intention to induce psychological or physiological changes., Salvinorins are a group of natural chemical compounds and their structural analogs . Several salvinorins have been isolated from Salvia divinorum . They are classified as diterpenoid furanolactones . Salvinorin A is a hallucinogen with dissociative effects . Several salvinorins have been isolated and characterized ., Oaxaca (, , from ), officially the Free and Sovereign State of Oaxaca, is one of the 31 states which, along with the Federal District, make up the 32 federative entities of Mexico. It is divided into 570 municipalities, of which 418 (almost three quarters) are governed by the system of Usos y costumbres (customs and traditions) with recognized local forms of self governance. Its capital city is Oaxaca de Juárez., Subject: salvinorin, Relation: subclass_of, Options: (A) affect (B) agriculture (C) amnesia (D) analgesia (E) anesthesia (F) area (G) artificial selection (H) capital (I) case (J) chemical substance (K) city (L) class (M) cloud (N) cover (O) depression (P) federal district (Q) federal republic (R) forest (S) general (T) history (U) latin (V) material (W) molecule (X) nahuatl (Y) nation (Z) ocean ([) plant (\) population (]) republic (^) sea (_) second (`) seed (a) sixth (b) ska (c) sound (d) sovereign state (e) spanish (f) square (g) state (h) system (i) world
