Ayahuasca is a South American psychoactive brew, traditionally used by Indigenous cultures and folk healers in Amazon and Orinoco basins for spiritual ceremonies, divination, and healing a variety of psychosomatic complaints. Originally restricted to areas of Peru, Brazil, Colombia and Ecuador, in the middle of 20th century it became widespread in Brazil in context of appearance of syncretic religions that uses ayahuasca as a sacrament, like Santo Daime, União do Vegetal and Barquinha, which blend elements of Amazonian Shamanism, Christianity, Kardecist Spiritism, and African-Brazilian religions such as Umbanda, Candomblé and Tambor de Mina, later expanding to several countries across all continents, notably the United States and Western Europe, and, more incipiently, in Eastern Europe, South Africa, Australia, and Japan.
Entheogens are psychoactive substances that induce alterations in perception, mood, consciousness, cognition, or behavior for the purposes of engendering spiritual development or otherwise in sacred contexts. Anthropological studies have 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, healings, asceticism, prayer, trance, rituals, chanting, imitation of sounds, 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.
Harmala alkaloids are several alkaloids that increase effects of reward system neurotransmitter dopamine by acting as monoamine oxidase inhibitors (MAOIs). These alkaloids are found in the seeds of Peganum harmala, as well as leaves of tobacco and coffee beans. The alkaloids include harmine, harmaline, harmalol, and their derivatives, which have similar chemical structures, hence the name "harmala alkaloids". These alkaloids are of interest for their use in Amazonian shamanism, where they are derived from other plants. Harmine, once known as telepathine and banisterine, is a naturally occurring beta-carboline alkaloid that is structurally related to harmaline, and also found in the vine Banisteriopsis caapi. Tetrahydroharmine is also found in B. caapi and P. harmala. Dr. Alexander Shulgin has suggested that harmine may be a breakdown product of harmaline. Harmine and harmaline are reversible inhibitors of monoamine oxidase A (RIMAs). They can stimulate the central nervous system by inhibiting the metabolism of monoamine compounds such as serotonin and norepinephrine.

A drug is any chemical substance that when consumed causes a change in an organism's physiology, including its psychology, if applicable. Drugs are typically distinguished from food and other substances that provide nutritional support. Consumption of drugs can be via inhalation, injection, smoking, ingestion, absorption via a patch on the skin, suppository, or dissolution under the tongue.

The stoned ape theory is a controversial theory first proposed by American ethnobotanist and mystic Terence McKenna in his 1992 book Food of the Gods. The theory claims that the transition from Homo erectus to Homo sapiens and the cognitive revolution was caused by the addition of psilocybin mushrooms, specifically the mushroom Psilocybe cubensis, into the human diet around 100,000 years ago. Using evidence largely based on studies from Roland L. Fischer et. al from the 1960s and 1970s, he attributed much of the mental strides made by humans during the cognitive revolution to the effects of psilocybin intake found by Fischer.
Traditional Brazilian medicine includes many native South American elements, and imported African ones. It is predominantly used in areas where indigenous groups and African descendants reside, like in the northeast coast, nearly all interior regions including Amazon regions, savannahs, rainforest, foothills, and Pantanal. According to Romulo R. N. Alves, "although Brazil's health system is public...use of traditional remedies and rituals provide an economical way of healing for much of the populace, but that also does not mean that wealthy Brazilians don't seek it out as well. Traditional medicine is a deep part of Brazilian heritage."
Michael James Harner was an anthropologist, educator and author. His 1980 book, The Way of the Shaman: a Guide to Power and Healing, has been foundational in the development and popularization of Core shamanism as a new age path of personal development for adherents of neoshamanism. He also founded the Foundation for Shamanic Studies.
In general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. Herbs generally refers to the leafy green or flowering parts of a plant, while spices are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits.

Researchers have noted the relationship between psychedelics and ecology, particularly in relation to the altered states of consciousness (ASC) produced by psychedelic drugs and the perception of interconnectedness expressed through ecological ideas and themes produced by the psychedelic experience. This is felt through the direct experience of the unity of nature and the environment of which the individual is no longer perceived as separate but intimately connected and embedded inside.

The International Center for Ethnobotanical Education, Research, and Service (ICEERS) is a non-profit organization (NPO), headquartered in Barcelona. ICEERS is dedicated to transforming society's relationship with psychoactive plants by engaging with some of the fundamental issues resulting from the globalization of ayahuasca, iboga, and other ethnobotanicals. Founded in 2009, ICEERS is registered as a non-profit organization, and has charitable status in the Netherlands and Spain, and through partner organizations in the US and UK. ICEERS also has consultative status with the United Nations’ ECOSOC.
