Research with psychedelic drugs has mainly focused on isolated compounds. However, this approach is challenged by the "polypharmacology" paradigm. In this Viewpoint, we suggest that we may be missing something if we do not use the whole product in the case of ayahuasca or Psilocybe mushrooms. After describing how research on psychedelic drugs can be effectively combined with the...

This story is about the twentieth-century ethnobotanist, Richard Evans Schultes (1915-2001), and his research on hallucinogenic plants. Ethnobotany can contribute directly to science and technology studies in that the discipline makes cultural ways of knowing its scientific subject. Ethnobotanists must learn about plants through people, and are not able to conceal their interactions with...

Mushrooms containing psilocybin have been used in Indigenous healing ceremonies in Mesoamerica since at least the sixteenth century. However, the sacramental use of mushrooms was only discovered by Westerners in the early to mid-twentieth century. Most notably, the meeting between amateur mycologist Robert Gordon Wasson and Mazatec curandera María Sabina in 1955 resulted in the widespread...

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...

The present study explored the phenomenological characteristics of anomalous experiences (AEs) reported during Umbanda rituals, a mediumistic Brazilian religion, with the aim of comparing AEs reported during rituals involving the use of Ayahuasca (an entheogen frequently used in some Umbanda contexts) and rituals without the use of this substance. In order to do so, we compared individuals with...
