Datura is a genus of nine species of poisonous, vespertine-flowering plants belonging to the family Solanaceae. They are commonly known as thornapples or jimsonweeds, but are also known as devil's trumpets. Other English common names include moonflower, devil's weed, and hell's bells. All species of Datura are poisonous and potentially psychoactive, especially their seeds and flowers, which can cause respiratory depression, arrhythmias, fever, delirium, hallucinations, psychosis, and even death if taken internally. Due to their effects and symptoms, they have occasionally been used not only as a poison, but also as hallucinogens by various groups throughout history. Traditionally, psychoactive administration of Datura species has often been associated with witchcraft and sorcery or similar practices in many cultures, including the Western world. Certain common Datura species have also been used ritualistically as entheogens by some Native American groups. Nonpsychoactive use of the plant is usually done for medicinal purposes, and the alkaloids present in plants of the Datura genus have long been considered traditional medicines in both the New and Old Worlds due to the presence of the alkaloids scopolamine and atropine, which are also produced by Old World plants such as Hyoscyamus niger, Atropa belladonna, and Mandragora officinarum.
An entheogen is a psychoactive substance that induces alterations in perception, mood, consciousness, cognition, or behavior for the purposes of engendering spiritual development or otherwise in sacred contexts. Anthropological study has established that entheogens are used for religious, magical, shamanic, or spiritual purposes in many parts of the world. Entheogens have traditionally been used to supplement many diverse practices geared towards achieving transcendence, including divination, meditation, yoga, sensory deprivation, asceticism, prayer, trance, rituals, chanting, hymns like peyote songs, drumming, and ecstatic dance. The psychedelic experience is often compared to non-ordinary forms of consciousness such as those experienced in meditation, near-death experiences, and mystical experiences. Ego dissolution is often described as a key feature of the psychedelic experience.
Banisteriopsis caapi, also known as ayahuasca, jagube, caapi or yagé, is a South American liana of the family Malpighiaceae. It is one half of ayahuasca, a decoction with a long history of its entheogenic use and its status as a "plant teacher" among the Indigenous peoples of the Amazon rainforest.
Ipomoea is the largest genus in the flowering plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, water convolvulus or kangkung, sweet potato, bindweed, moonflower, etc.
Grevillea is a diverse genus of about 360 species of evergreen flowering plants in the family Proteaceae, native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands east of the Wallace Line. It was named in honour of Charles Francis Greville, an 18th century patron of botany and co-founder of the Royal Horticultural Society. The species range from prostrate shrubs less than 50 cm (20 in) tall to trees 35 m (115 ft) tall. Common names include grevillea, spider flower, silky oak and toothbrush plant. Closely related to the genus Hakea, the genus gives its name to the subfamily Grevilleoideae.
Deliriants are a class of hallucinogen. The term was introduced by David F. Duncan and Robert S. Gold to distinguish these drugs from psychedelics and dissociatives, such as LSD and ketamine, respectively, due to their primary effect of causing delirium, as opposed to the more lucid states produced by such other hallucinogens as those represented by psychedelics and dissociatives. The term is generally used to refer 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). Despite their long history of usage, deliriants are regarded as the least-studied class of hallucinogens in terms of their behavioral and neurological profiles.
The Thymelaeaceae are a cosmopolitan family of flowering plants composed of 50 genera and 898 species. It was established in 1789 by Antoine Laurent de Jussieu. The Thymelaeaceae are mostly trees and shrubs, with a few vines and herbaceous plants.
Nicandra physalodes is a species of flowering plant in subfamily Solanoideae of the nightshade family. It is known by the common names apple-of-Peru and shoo-fly plant. It is thought originally to have been native to western South America, including Peru, and is known elsewhere as an introduced and ruderal species – sometimes as a weed – in tropical, subtropical and, to a lesser extent, temperate areas all over the world. It has also long been cultivated as an ornamental plant for its attractive flowers and curious fruits and has been adopted into the traditional medicine of countries far-removed from its original home.
Nothofagus pumilio, the lenga beech, is a deciduous tree or shrub in the Nothofagaceae family that is native to the southern Andes range, in the temperate forests of Chile and Argentina to Tierra del Fuego, from 35° to 56° South latitude. This tree is in the same genus as the coihue. It regenerates easily after fires. The wood is of good quality, moderate durability, and is easy to work with. It is used in furniture, shingles and construction and sometimes as a substitute for American black cherry in the manufacturing of cabinets.
Carl Daniel Friedrich Meissner was a Swiss botanist.
Desfontainia is a genus of flowering plants placed currently in the family Columelliaceae, though formerly in Loganiaceae, Potaliaceae, or a family of its own, Desfontainiaceae.
Christian Rätsch is a German anthropologist and writer on topics like ethnopharmacology, psychoactive plants and animals.
Passerina is a genus in the plant family Thymelaeaceae. They are ericoid bushes growing largely in fynbos and other Southern African scrub habitats.
Beilschmiedia is a genus of trees and shrubs in family Lauraceae. Most of its species grow in tropical climates, but a few of them are native to temperate regions, and they are widespread in tropical Asia, Africa, Madagascar, Australia, New Zealand, North America, Central America, the Caribbean, and South America. The best-known species to gardeners in temperate areas are B. berteroana and B. miersii because of their frost tolerance. Seeds of B. bancroftii were used as a source of food by Australian Aborigines. Timbers of some species are very valuable.
Latua pubiflora(Griseb.) Baillon, is the single species of the monotypic genus LatuaPhil., endemic to the coastal mountains of southern Chile. A shrub or small tree to 10 m in height, bearing attractive, magenta-to-red, hummingbird-pollinated flowers, it is extremely poisonous – hallucinogenic (deliriant) in smaller doses – due to tropane alkaloid content and is used by Chilean machi (shamans) of the Mapuche–Huilliche people in traditional medicine, as a poison and to enter trance states. Its elegant flowers and yellow tomato-like fruit are attractive enough to merit its cultivation as an ornamental.
The Mapuche conflict is the name given to the conflict originated from the claims of indigenous Mapuche communities and organizations to the States of Chile and Argentina. The activist in favor of the 'Mapuche cause' claim greater autonomy, recognition of rights, and the 'recovery' of land since the Chilean transition to democracy.
Psychoactive plants are plants, or preparations thereof, that upon ingestion induce psychotropic effects. As stated in a reference work:
Psychoactive plants are plants that people ingest in the form of simple or complex preparations in order to affect the mind or alter the state of consciousness.
The Solanaceae, or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Stellera is a genus of flowering plant in the family Thymelaeaceae, with a single species Stellera chamaejasme found in mountainous regions of Central Asia, China, Siberia and South Asia. S. chamaejasme is a herbaceous perennial plant with heads of white, pink or yellow flowers, grown as an ornamental plant in rock gardens and alpine houses, but considered a weed playing a rôle in the desertification of grasslands in parts of its native range. Like many others of its family, it is a poisonous plant with medicinal and other useful properties.
