Whole Organisms or Pure Compounds? Entourage Effect Versus Drug Specificity

April 29, 2018 / Ayahuasca, Cacti / Mescaline, Ethnobotany, Indigenous use, Mushrooms / Psilocybin, Papers, Psychopharmacology, Psychotherapy, Publications, Spirituality / By /

Abstract

As the therapeutic use of sacred plants and fungi becomes increasingly accepted by Western medicine, a tug of war has been taking place between those who advocate the traditional consumption of whole organisms and those who defend exclusively the utilization of purified compounds. The attempt to reduce organisms to single active principles is challenged by the sheer complexity of traditional medicine. Ayahuasca, for example, is a concoction of at least two plant species containing multiple psychoactive substances with complex interactions. Similarly, cannabis contains dozens of psychoactive substances whose specific combinations in different strains correspond to different types of therapeutic and cognitive effects. The “entourage effect” refers to the synergistic effects of the multiple compounds present in whole organisms, which may potentiate clinical efficacy while attenuating side effects. In opposition to this view, mainstream pharmacology is adamant about the need to use purified substances, presumably more specific and safe. In this chapter, I will review the evidence on both sides to discuss the scientific, economic, and political implications of this controversy. The evidence indicates that it is time to embrace the therapeutic complexity of psychedelics.

Ceremonial ‘Plant Medicine’ use and its relationship to recreational drug use: an exploratory study

March 30, 2018 / Addiction, Ayahuasca, Ethnobotany, Indigenous use, Mushrooms / Psilocybin, Papers, Psychology, Publications, Sociology, Spirituality / By / , ,

Abstract

Background: The ceremonial use of psychoactive/hallucinogenic plant based drugs, such as ayahuasca, psilocybin and others, is a growing trend in the United States (US) and globally. To date, there has been little research documenting how many people are using psychoactive substances in this context, who the users are, what benefits/risks exist in the use of these drugs and the relationship between ceremonial drug use and recreational drug use.
In this paper we describe a cohort of plant medicine facilitators in the US and explore how they differentiate plant medicine use from recreational drug use.
Methods: Using modified ethnography, individual interviews were conducted in 2016 with 15 participants who are currently facilitating plant medicine ceremonies in the US. Descriptive content analysis was performed to discover themes and to inform a larger mixed-method study.
Results: Ceremonial drug use was seen by participants as a natural healing and treatment modality used in the context of community and ritual. Three main themes were identified relating to participants’ differentiation between ceremonial plant medicine use and recreational drug use: (1) participants see a clear delineation between plant medicine use and recreational drug use; (2) plant medicine is seen as a potential treatment for addiction, but concerns exist regarding potential interference with recovery; and (3) plant medicine use may influence recreational use.
Conclusions: More research is needed on who is using plant medicine, motivators for use, perceived and real risks and benefits of plant medicine use and harm reduction techniques regarding safe ingestion.

Ayahuasca: Psychological And Physiologic Effects, Pharmacology And Potential Uses In Addiction And Mental Illness

January 24, 2018 / Addiction, Ayahuasca, Depression, Indigenous use, Papers, Psychiatry, Psychology, Psychotherapy, Publications / By / , , ,

Abstract

Ayahuasca, a traditional Amazonian decoction with psychoactive properties, is made from bark of the Banisteriopsis caapi vine (contains beta-carboline alkaloids) and leaves of the Psychotria viridis bush (supply the hallucinogen N,N-dimethyltryptamine (DMT)). Originally used by indigenous shamans for the purposes of spirit communication, magical experiences, healing, and religious rituals, across several South American countries ayahuasca has been incorporated into folk medicine and spiritual healing, and several Brazilian churches use it routinely to foster spiritual experience. More recently it is being used in Europe and North America, not only for religious or healing reasons, but also for recreation.
OBJECTIVE:
To review ayahuasca’s behavioral effects, possible adverse effects, proposed mechanisms of action and potential clinical uses in mental illness.
METHOD:
We searched Medline, in English, using the terms ayahuasca, dimethytryptamine, Banisteriopsis caapi, and Psychotria viridis and reviewed the relevant publications.
RESULTS:
The following aspects of ayahuasca are summarized: Political and legal factors; acute and chronic psychological effects; electrophysiological studies and imaging; physiological effects, safety and adverse effects; pharmacology; potential psychiatric uses.
CONCLUSION:
Many years of shamanic wisdom have indicated potential therapeutic uses for ayahuasca, and many present day studies suggest that it may be useful for treating various psychiatric disorders and addictions. The side effect profile appears to be relatively mild, but more detailed studies need to be done. Several prominent researchers feel that government regulations with regard to ayahuasca should be relaxed so that it could be provided more readily to recognized credible researchers to conduct comprehensive clinical trials.

Influence of Environmental Factors and Cultural Methods on the Content of N,N‑Dimethyltryptamine in Psychotria viridis (Rubiaceae)

December 6, 2017 / Ayahuasca, Chemistry, DMT, Ethnobotany, Indigenous use, Papers, Publications / By / , , , , , ,

Abstract

Psychotria viridis is one of the species that produces N,N-dimethyltryptamine. Its decoction together with other species, such as Banisteriopsis caapi, produces ayahuasca, a beverage used for ritualistic and medicinal purposes. The goal of this study was to understand how environmental factors and cultivation methods influenced the content of N,N-dimethyltryptamine in P. viridis. Over all four seasons, leaf samples were collected from 25 different locations in 14 Brazilian states, and Federal District. Environmental parameters, micro and macronutrients, plant characteristics, information on farming methods were correlated with N,N-dimethyltryptamine content, determined by gas chromatography coupled to mass spectrometry (GC-MS). Greatest effects on the N,N-dimethyltryptamine amount were associated with seasonality, altitude, latitude and biome type. A positive correlation between N and Mg content and N,N-dimethyltryptamine levels was statistically established. By regression analysis, the adequate foliar nutrient levels that would result in the concentration of N,N-dimethyltryptamine in cultivated plants similar to that of Amazonian P. viridis were equated.

Mystical mobilities and entheogenic Latin America

September 14, 2017 / Anthropology, Ayahuasca, Cacti / Mescaline, Indigenous use, Mushrooms / Psilocybin, Mystical experiences, Papers, Publications, Religious studies, Spirituality / By /

Abstract

In this paper, I seek to explore the concept of mystical mobility as a way of addressing travelling and thus using mobility resources that go beyond the transport agenda. I propose to address innovative paths and research questions by discussing alternative cultural geographies in order to seriously reconsider the concept of mobility in a broad sense. The work aims to introduce the notion of ‘mystical mobility’ and its relationship with entheogens (i.e. psychoactive substances) as a new component of mobility studies, also considering how physical and mystical trips are (or are not) combined.

Ayahuasca: what mental health professionals need to know

July 1, 2017 / Addiction, Anxiety disorders / PTSD, Ayahuasca, Depression, Ethnobotany, Indigenous use, Papers, Psychiatry, Psychology, Psychotherapy, Publications, Safety / By / , ,

Abstract

Background

Ayahuasca is a psychoactive ethnobotanical concoction that has been used for decades by indigenous groups of the Northwestern Amazon and by syncretic religious organizations for ritual and therapeutic purposes. In the last two decades, it is being used worldwide in evolving practices. Ayahuasca seem to therapeutic effects, but controlled studies are lacking. Moreover, its safety and toxicity are not completely understood.

Objectives

To present an overview of the effects of ayahuasca based on the most recent human studies.

Methods

Narrative review.

Results

Ayahuasca administration in controlled settings appears to be safe from a subjective and physiological perspective, with few adverse reactions being reported. More frequent adverse reactions occur in non-controlled settings. Prolonged psychotic reactions are rare and seem to occur especially in susceptible individuals. Ayahuasca showed antidepressive, anxiolytic, and antiaddictive effects in animal models, observational studies, and in open-label and controlled studies.

Discussion

Ayahuasca administration in controlled settings appear to be safe. Moreover, ayahuasca seem to have therapeutic effects for treatment-resistant psychiatric disorders that should be further investigated in randomized controlled clinical trials. However, medical complications and cases of prolonged psychotic reactions have been reported, and people with personal or family history of psychotic disorders should avoid ayahuasca intake.

The State of the Arts of the Study of Indigenous Religious Traditions in South America

May 16, 2017 / Anthropology, Ayahuasca, Ethnobotany, Indigenous use, Mystical experiences, Papers, Religious studies / By /

Abstract

This article reviews the principal tendencies in the contemporary studies of indigenous South American religious traditions. It divides the field into studies of socioreligious formations (particularistic and universalistic formations, more specifically) and studies of cosmologies or worldviews (so-called perspectivism). It then discusses two recent, pioneering biographies of South American shamans which, more than any other in the field, offer original approaches to understanding shamanic historical consciousness, cosmopolitics, the constant struggles of shamanic spirits to sustain the cosmos against sorcery spirits that threaten to undermine the cosmic order.
