After a two-decade hiatus in which research on psychedelics was essentially halted, placebo-controlled clinical trials of psychedelic-assisted therapy for mental health conditions have begun to be published. We identified nine randomized, placebo-controlled clinical trials of psychedelic-assisted therapy published since 1994. Studies examined psilocybin, LSD (lysergic acid diethylamide),...
Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine) is an indole-based secondary metabolite produced by numerous species of mushrooms. South American Aztec Indians referred to them as teonanacatl, meaning "god's flesh," and they were used in religious and healing rituals. Spanish missionaries in the 1500s attempted to destroy all records and evidence of the use of these mushrooms. Nevertheless,...

Ayahuaska, zwana również „lianą duszy”, „pnączem duszy” to rytualny psychodelik podawany tradycyjnie w formie wywaru roślinnego, od stuleci stosowany przez rdzenną ludność Ameryki Południowej, a w ostatnich 25 latach również w krajach Europy, Azji, Afryki, Australii, w Kanadzie i Stanach Zjednoczonych Ameryki Północnej. Jej aktywność biologiczna wynika z zawartości N,N- dimetrylotryptaminy...
IntroductionAyahuasca is a beverage composed by a mixture of herbs which contain the compound N,N-dimethyltriptamine (DMT) and the β-carbolines. Although its use is legalized in Brazil only for religious and spiritual ceremonies, there is a growing black market specialized in the distribution of these compounds in form of herbal material through internet and mail. The purpose of this work was...
Ayahuasca is a tea with psychoactive properties used by indigenous peoples of South America obtained from the infusion of two plants, Banisteriopsis caapi and Psychotria viridis.From the junction of these plants is obtained a preparation rich in β-carbonyl alkaloids, which promote blockade of Monoaminoxidase (MAO) and considerable concentrations of N, N-dimethyltryptamine (DMT).MAO degrades DMT...
Psychedelic drugs such as psilocybin, LSD and DMT are known to induce powerful alterations in phenomenology. Perhaps of most philosophical and scientific interest is their capacity to disrupt and even “dissolve” one of the most primary features of normal experience: that of being a self. Such “peak” or “mystical” experiences are of increasing interest for their potentially transformative...
Increasing prevalence and burden of major depressive disorder presents an unavoidable problem for psychiatry. Existing antidepressants exert their effect only after several weeks of continuous treatment. In addition, their serious side effects and ineffectiveness in one-third of patients call for urgent action. Recent advances have given rise to the concept of psychoplastogens. These compounds...
Ketamine, N,N-dimethyltryptamine (DMT), and other psychoplastogens possess enormous potential as neurotherapeutics due to their ability to potently promote neuronal growth. Here, we report the first-ever structure-activity relationship study with the explicit goal of identifying novel psychoplastogens. We have discovered several key features of the psychoplastogenic pharmacophore and used this...
Serotoninergic hallucinogens include drugs such as lysergic acid diethylamide (LSD), dimethyltryptamine (DMT) and psilocybin. Recent trials with single/few doses of these compounds show that they induce rapid and sustained antidepressive, anxiolytic, and antiaddictive effects. These effects are also observed in religious groups using the DMT-containing brew ayahuasca. The agonist action of...
