The last few decades have been characterised by a resurgence in research and clinical interest in classic serotonergic psychedelics including N,N-dimethyltryptamine (DMT), lysergic acid diethylamide (LSD) and psilocybin, with a growing body of literature pointing to their treatment potential. Ayahuasca is a psychedelic brew commonly composed of plants carrying the psychoactive compound DMT, and...
AbstractThis chapter delves into the meandrous trajectory of DMT extracted from Mimosa tenuifora (black jurema) along traditional, scientific, and neo-shamanic uses. Chemist Jonathan Ott popularized a recipe of anahuasca (sometimes called juremahuasca or pharmahuasca) mixing the root bark powder from the tree that grows in semi-arid regions of tropical America with Syrian rue as a source of...
Festival in the state of Bahia, a Umbanda terreiro in Pernambuco and a Catimbó ritual in Rio Grande do Norte. The first experience was provided by a smokable version known as changa that became popular among psychonauts. Changa is supposed to have been invented in Australia, but using acacia instead of jurema as the source of DMT, a preparation also referred to as “aussiewaska,” according to...
Classical psychedelics such as N,N-dimethyltryptamine (DMT) modulate consciousness via serotonergic receptor agonism, and are increasingly investigated for their psychotherapeutic potential. When combined with the monoamine oxidase A (MAO-A) inhibitor harmine—mimicking the pharmacological profile of ayahuasca—oral DMT induces a psychedelic experience lasting 4–5 h. While some neuroimaging...
Recent psychedelic research has shown that compounds such as psilocybin, DMT, ayahuasca, and 5-MeO-DMT can induce acute altered states involving self-dissolution, altered reality-status, and heightened meaning attribution. Historical and cross-cultural evidence likewise suggests that nonordinary states have often been embedded within ritual, initiation, contemplative discipline, and structured...

Przedmiot badań: W ostatnich latach obserwuje się rosnące zainteresowanie wykorzystaniem naturalnych halucynogenów w leczeniu zaburzeń psychicznych, uzależnień czy bólu. Substancje takie jak psylocybina, ayahuasca, ibogaina czy meskalina poddawane są ocenie w badaniach klinicznych, które wskazują na ich potencjał terapeutyczny, zwłaszcza w leczeniu depresji lekoopornej, zespołu stresu...
Background: Psychedelic-assisted therapy is gaining renewed attention as a potential treatment for various mental disorders. Despite increasing numbers of randomized controlled trials (RCTs) and meta-analyses, a comprehensive synthesis of the evidence across different substances and indications is lacking. This umbrella review aims to evaluate the effectiveness and safety of...
Purpose A systematic review was conducted to synthesize the efficacy, safety, and tolerability of psychedelics including ketamine, MDMA, ayahuasca, LSD, DMT, ibogaine, and psilocybin in the treatment of PTSD. Recent Findings Among 5,155 studies identified, 42 studies met criteria and were included in our systematic review. Ketamine consistently produced rapid symptom improvement that attenuated...

Psychedelic-assisted therapy offers rapid and profound benefits for treatment-resistant psychiatric conditions but remains constrained by the need for intensive, clinic-based administration. Concurrently, advances in digital health technologies have introduced scalable tools. This systematic review evaluates the safety, efficacy, and implementation of digitally enabled psychedelic-assisted...
Scientific interest in psychedelics, documented since the nineteenth century, has recently resurged after decades of prohibition. Contemporary research highlights their therapeutic potential in treatment-resistant psychiatric disorders, alongside their heuristic value for studying brain networks and consciousness. This chapter reviews the historical trajectory, traditional uses, mechanisms of...
