Hallucinogen Ayahuasca (usually pronounced /aɪjəˈwæskə/ or /ˈaɪjəˈwɑːskə/), also commonly called yagé (/jɑːheɪ/), is a brew of various psychoactive infusions or decoctions prepared with the Banisteriopsis caapi vine. It is either mixed with the leaves of dimethyltryptamine (DMT)-containing species of shrubs from the genus Psychotria or with the leaves of the Justicia pectoralis plant which doesn't contain DMT. The brew, first described academically in the early 1950s by Harvard ethnobotanist Richard Evans Schultes, who found it employed for divinatory and healing purposes by the native peoples of Amazonian Peru, is known by a number of different names (see below).[1]
It has been reported that some effects can be had from consuming the caapi vine alone, but that DMT-containing plants (such as Psychotria) remain inactive when drunk as a brew without a source of monoamine oxidase inhibitor (MAOI) such as B. caapi. How indigenous peoples discovered the synergistic properties of the plants used in the ayahuasca brew remains unclear. While many indigenous Amazonian people say they received the instructions directly from plants and plant spirits, researchers have devised a number of alternative theories to explain its discovery.[1]
People who have consumed ayahuasca report having spiritual revelations regarding their purpose on earth, the true nature of the universe as well as deep insight into how to be the best person they possibly can.[2] This is viewed by many as a spiritual awakening and what's often described as a rebirth.[3] In addition it is often reported that individuals can gain access to higher spiritual dimensions and make contact with various spiritual or extra dimensional beings who can act as guides or healers.[4]
It's nearly always said that people experience profound positive changes in their life subsequent to consuming ayahuasca[5] and it is often viewed as one of the most effective tools of enlightenment.[6] However, during an ayahuasca experience, people sometimes report nausea, diarrhea, and cold flashes. Additionally, vomiting can follow ayahuasca ingestion; this purging is considered by many shamans and experienced users of ayahuasca to be an essential part of the experience as it represents the release of negative energy and emotions built up over the course of one's life.[7]
Further, it should be noted that the ingestion of ayahuasca can cause significant, but temporary emotional and psychological distress. There are many reports of miraculous physical as well as emotional and spiritual healing resulting from the use of ayahuasca.[8] Long-term negative effects are not known.[9]
For various reasons shamans and experienced users of ayahuasca strongly advise against consuming ayahuasca when not in the presence of one or several well-trained shamans. [10] It is believed that one of the core functions of a shaman is to provide a kind of spiritual protection that keeps negative entities away. This includes not only spirits but other shamans referred to as brujos who practice a form of shamanic witchcraft and can enter the space and attempt to harm people having consumed ayahuasca. [11]
Additionally it should be noted that these brujos often masquerade as real shamans enticing tourists to drink ayahuasca in their presence. Real shamans believe one of the purposes for this is to steal ones energy and or power, which they believe every person has a stockpile of. [12] It is very important for individuals seeking an ayahuasca experience to find a reputable shaman before hastily drinking with anyone who claims to be a shaman or offers one ayahuasca.[13]
Finally there are a number of pharmaceutical drugs that when taken in conjunction with ayahuasca can cause symptoms that range from intense sickness to death in rare cases. This is due to the MAOI that is present in the Banisteriopsis Caapi vine. Any anti-anxiety or antidepressant medication should strictly be avoided for at lease one week before and after an ayahuasca ceremony. It is recommended that if you are taking any medications that you consult your doctor well in advance.
Ayahuasca is used largely as a religious sacrament. Users of ayahuasca in non-traditional contexts often align themselves with the philosophies and cosmologies associated with ayahuasca shamanism, as practiced among indigenous peoples like the Urarina of Peruvian Amazonia.[26] While non-native users know of the spiritual applications of ayahuasca, a less well-known traditional usage focuses on the medicinal properties of ayahuasca. When used for its medicinal purposes ayahuasca affects the human consciousness for less than six hours, beginning half an hour after consumption, and peaking after two hours. Ayahuasca also has cardiovascular effects, moderately increasing both heart rate and diastolic blood pressure. In some cases, individuals experience significant psychological stress during the experience. It is for this reason that extreme caution should be taken with those who may be at risk of heart disease.[27]
The psychedelic effects of ayahuasca include visual and auditory stimulation, the mixing of sensory modalities, and psychological introspection that may lead to great elation, fear, or illumination. Its purgative properties are important (known as la purga or "the purge"). The intense vomiting and occasional diarrhea it induces can clear the body of worms and other tropical parasites,[28] and harmala alkaloids themselves have been shown to be anthelmintic[29] Thus, this action is twofold; a direct action on the parasites by these harmala alkaloids (particularly harmine in ayahuasca) works to kill the parasites, and parasites are expelled through the increased intestinal motility that is caused by these alkaloids.

Dietary taboos are often associated with the use of ayahuasca.[30] In the rainforest, these tend towards the purification of one's self – abstaining from spicy and heavily-seasoned foods, excess fat, salt, caffeine, acidic foods (such as citrus) and sex before, after, or during a ceremony. A diet low in foods containing tyramine has been recommended, as the speculative interaction of tyramine and MAOIs could lead to a hypertensive crisis. However, evidence indicates that harmala alkaloids act only on MAO-A, in a reversible way similar to moclobemide (an antidepressant that does not require dietary restrictions). Dietary restrictions are not used by the highly urban Brazilian ayahuasca church União do Vegetal, suggesting the risk is much lower than perceived, and probably non-existent.[30]
In some areas[specify], it is even said that the chakruna or chaliponga admixtures are added only to make the brew taste sweeter.[citation needed] This is a strong indicator of the often wildly divergent intentions and cultural differences between the native ayahuasca-using cultures and psychedelics enthusiasts in other countries.
A visitor who wishes to become a "dietero" or "dietera", that is, a male or female apprentice-shaman learning the way of the teacher plants, undergoes a rigorous initiation. This can involve spending up to a year or more in the jungle. This initiation challenges and trains the initiate through extreme circumstances involving a special diet and numerous different plant medicines to complement the ayahuasca, the lack of western food and conveniences, the harsh environmental conditions of heavy rains, storms, intense heat, insects, and venomous animals. The initiate is also tested for their unwavering commitment to ayahuasca and the shaman who oversees the training.[citation
