Abstract:
This book offers a series of perspectives on the therapeutic potential of the ritual and clinical use of the Amazonian hallucinogenic brew ayahuasca in the treatment and management of various disorders. Biomedical and anthropological data on the use of ayahuasca for treating depression, PTSD, anxiety, substance dependence, eating disorders, and its role in psychological well-being, quality of life, enhancing cognition, and for coping with grief are presented and critiqued. The use of ayahuasca associated with psychotherapy is examined, alongside the challenges of integrating plant medicines into psychiatry. Further, some preliminary research with animals is introduced in which neural progenitor cells indicate that the alkaloids present in ayahuasca facilitate the formation of new neurons, suggesting that ayahuasca acts at multiple levels of neural complexity. The neurogenic effects of ayahuasca alkaloids open a new avenue of research with potential applications ranging from psychiatric disorders to brain damage and dementia. Chapters combine the review of published literature, personal experiences of the authors with the brew, and first-hand observation of the use of ayahuasca in different contexts. This book is especially timely as the growing scientific evidence of the safety and therapeutic potential of psychedelics such as MDMA and psilocybin increases the likelihood of their rescheduling and adoption into new treatment models.

Ayahuasca Healing and Science
Clancy Cavnar and Beatriz Labate
Foreword
Will the Queen Save Us?
Sidarta Ribeiro
1. Ayahuasca as a Versatile Therapeutic Agent: From Molecules to Metacognition and Back
Marta Valle, Elisabeth Domínguez-Clavé, Matilde Elices, Juan Carlos Pascual, Joaquim Soler, José A. Morales-García, Ana Pérez-Castillo, and Jordi Riba
In this chapter, we review the latest research on the neuroscience and therapeutic potential of ayahuasca. Currently, the type of research available ranges from in vitro experiments to clinical studies performed to assess the modulation of neural and psychological processes. We also discuss the most recently reported findings, including (a) the neurobiological effects of ayahuasca, (b) the psychological mechanisms underlying the potential therapeutic effects of ayahuasca, (c) ayahuasca-induced metabolic and connectivity changes, and (d) the possible link with mindfulness-related capacities and emotion regulation. We also examine the effects of ayahuasca at the cellular level to better explore the role of β-carbolines and the neurogenetic properties of these alkaloids. These important findings indicate that these compounds, which still play a minor role in the overall pharmacology of ayahuasca, merit greater attention. Our aim is to show the remarkable versatility of ayahuasca as a therapeutic agent. Ayahuasca interacts with the brain–mind complex on multiple levels, and could be a powerful tool to help patients with neuropsychiatric disorders who are unable to find relief through currently available treatments.
2. Recent Evidence on the Antidepressant Effects of Ayahuasca
Fernanda Palhano-Fontes, Sérgio Mota-Rolim, Bruno Lobão-Soares, Nicole Galvão-Coelho, Joao Paulo Maia-Oliveira, Dráulio B. Araújo
Depression is a mood disorder with profound negative effects on the individual’s quality of life and augmented suicidal risks. Despite substantial progress in the development of new antidepressants that have been made in the last decades, remission rates are modest, around 50% after the first treatment. Besides, antidepressants usually take about 2 weeks for the effects to take place. In the search for alternative treatments for depression, serotonergic psychedelics, such as ayahuasca, are emerging with promising results. Recent clinical trials have suggested a potential antidepressant effect of ayahuasca. In a first open-label trial, 17 patients with depression took part in a single ayahuasca session conducted in a hospital, and depressive symptoms were monitored by clinical scales to assess depression severity at 1, 2, 7, 14, and 21 days after the session. Depressive symptoms improved significantly already 1 day after the session, an improvement that persisted for 21 days. In a follow-up randomized placebo-controlled trial, 29 patients with treatment-resistant depression participated in a single session in a hospital, half took one dose of ayahuasca, and the other half with a placebo substance that, similar to ayahuasca, produced some gastrointestinal distress. We observed significant antidepressant effects of ayahuasca already 1 day after the session with ayahuasca, which was even more pronounced 7 days later. In addition to the antidepressant effects, we explored potential biological processes that might be related to the antidepressant effects observed. These included biochemical markers, functional magnetic resonance imaging (fMRI), and sleep electroencephalography (EEG). This chapter aims to review some general aspects of depression, discuss the motivations to use ayahuasca as a novel antidepressant, and present the latest scientific findings that should help clarify the mechanisms behind the observed antidepressant effect of ayahuasca.
3. Psychedelic Medicines: A Paradigm Shift from Pharmacological Substitution Towards Transformation-Based Psychiatry
Milan Scheidegger
While psychoactive drugs such as ketamine and psilocybin have been researched extensively in the past decades, scientific interest in ayahuasca has just started to grow, due to its potential therapeutic benefits. Beyond its traditional indigenous and mestizo use in the Amazon, ayahuasca is currently spreading all over the world as an alternative plant medicine in various ritualistic contexts. This rapid dissemination coincides with the observational evidence that ayahuasca facilitates transformational processes with beneficial health outcomes. However, more empirical research is needed to move beyond anecdotal evidence and further verify therapeutic efficacy and biomechanisms of ayahuasca under controlled conditions. The objective of this chapter is to outline future possibilities of ayahuasca-assisted therapies based on the biomedical literature on psychedelics and other contexts in which ayahuasca is used to support health and wellbeing. First, psychedelic medicines will be contrasted with standard psychopharmaceuticals as a novel treatment option that necessitates a paradigm shift from substitution- to transformation-based therapy. Second, various adaptogenic effects of ayahuasca will be reviewed, including effects on body, brain, and mental functioning. Third, a novel transformational psychotherapy framework will be introduced that outlines how ayahuasca could be used to support sustainable transformation. Finally, future research directions of developing pharmahuasca applications in clinical settings will be contrasted with traditional and indigenous contexts of ayahuasca use, highlighting the challenges of intercultural knowledge transfer.
4. Ayahuasca and Psychotherapy: Beyond Integration
Mauricio Diament, Bruno Ramos Gomes, Luis Fernando Tófoli
With the internationalization of ayahuasca and reports of its positive effects on mental health, the interest in its therapeutic potential is increasing. Additionally, the different uses of ayahuasca may elicit wide-ranging psychological and emotional experiences. Therefore, the therapeutic use of ayahuasca can—and should—be appreciated from a psychotherapeutic point of view. This approach follows, but only to a certain extent, the already established paradigm of psychedelic-assisted psychotherapy. The effects of ayahuasca include bodily, emotional, and experiential changes to the experience of self and world, both during its acute effect and in the days after, and several of them may be related to its psychotherapeutic effect. In this chapter, the association of ayahuasca and psychotherapy will be discussed through the review of existent literature, the authors’ professional experience, and remarks about possible new paths in this field. Some points discussed here include: the role of the experience for the individual, suffering and challenging experiences with the brew, ayahuasca visions, the generation of content to be used in psychotherapy, the mediation of a “plant third party,” integration processes, and the encounter of ayahuasca with well-established psychotherapeutic schools.
5. A Qualitative Assessment of Risks and Benefits of Ayahuasca for Trauma Survivors
Jessica L. Nielson, Julie D. Megler, Clancy Cavnar
The use of ayahuasca for healing trauma and resolving associated symptoms has gained increasing attention recently. As a result, a surge of trauma survivors has converged on healing centers around the world in pursuit of ayahuasca therapy. Although research into ayahuasca has suggested it is safe and holds great therapeutic potential for mental health disorders, the potential for harm has been highlighted in recent years, particularly around set and setting with inexperienced facilitators and centers exploiting this rapidly growing market. The current study reports on data from a retrospective cross-sectional online survey of ayahuasca users either with or without a self-reported history of post-traumatic stress disorder (PTSD). Data reported here capture the potential risks of ayahuasca use in people with a history of PTSD and how they compare to the reported benefits. Results suggest that while most people find ayahuasca to be helpful (79–97%) and not dangerous (67–76%), people with a history of PTSD were 10% more likely to disclose information about dangerous experiences associated with taking ayahuasca, compared to those with no reported history of PTSD. Qualitative assessments of open-ended responses regarding dangerous experiences included feelings that the facilitators were inexperienced, not having sufficient physical and psychological support, inadequate facilities for purging, overcrowding in ceremonies, lack of follow-up care, and insufficient screening of participants with psychotic disorders who became violent. While most people found the experience to be helpful and healing, people are reporting unfavorable responses to ayahuasca, particularly those with a history of PTSD. Further investigation is necessary to develop best practices that ensure safety for participants with PTSD when seeking ayahuasca therapy.
6. Ayahuasca and Childhood Trauma: Potential Therapeutic Applications
Daniel Perkins, Jerome Sarris
There is increasing evidence that ayahuasca may have therapeutic efficacy in the treatment of mood, anxiety, and substance use disorders. Another potential area of application relates to individuals who have experienced childhood adverse experiences. Exposure to such traumatic stressors during childhood has been associated with later life mental and physical health conditions, health risk behaviors, and alcohol and substance use disorders, as well as broader negative effects on well-being and life satisfaction. Moreover, the number of traumatic childhood exposures is strongly correlated with the level of increased risk and overall symptom complexity. Such early trauma is associated with vast individual and societal costs and particularly challenging to treat due to a pervasive and multifaceted symptomology. There have been various notions advanced regarding the therapeutic processes associated with ayahuasca consumption that could be relevant for work in this area. These include the potential to revisit and reconceptualize adverse childhood events; possible therapeutic effects relating to depression, anxiety, and substance use disorders; potential neurobiological and physiological benefits; as well as enhanced self-awareness and broader well-being. This chapter reviews the core aspects, presentation, and impacts of childhood trauma in later life. It then outlines potential areas in which ayahuasca may support the treatment of such individuals, drawing on existing evidence and early responses from a global study of ayahuasca drinkers.
7. Acute and Long-Term Effects of Ayahuasca on (Higher-Order) Cognitive Processes
Natasha L. Mason, Kim P. C. Kuypers
There is increasing evidence of the potential therapeutic value of the psychedelic brew ayahuasca for disorders like depression, PTSD, and anxiety. While the focus has been on ayahuasca’s capacity to reduce symptoms of these disorders, including enhancing mood state and well-being, little attention has been paid to the (higher-order) cognitive processes that may be enhanced or that may play a role in this. Examples of such processes include flexible (creative) thinking, empathy, and emotion regulation, which are crucial for everyday interactions and cooperation, and have been found to be decreased in certain pathological populations. The aim of the present chapter is to review the acute and long-term effects of ayahuasca on (higher-order) cognitive processes, such as flexible (creative) thinking, empathy, and emotion regulation, and look for the link between these cognitive effects and subjective mood state and well-being.
Findings show that, although objective evidence is limited due to a scarcity of studies, previous studies with ayahuasca and similar psychedelics, like psilocybin and LSD, support the notion that ayahuasca can enhance previously mentioned higher-order cognitive processes. Importantly, evidence is given to suggest that this enhancement outlasts the acute stage, thus potentially persisting over time. Unfortunately, no study assessed the relationship between these cognitive effects and mood and well-being.
It is concluded that, while these findings partially explain why ayahuasca has therapeutic utility in the treatment of certain psychopathologies, future clinical research into the therapeutic effects of ayahuasca could assess the relationship between the effect on (higher-order) cognitive and emotional processes and mood and well-being and test the role both play in symptom alleviation in the pathological population in the short and longer term.
8. Healing with the Brew: Ayahuasca’s Reconfiguration of “Addiction”
Piera Talin
This chapter provides an ethnographically grounded, qualitative analysis of the experiences of people recovering from substance dependence among Italian and Brazilian chapters of the Santo Daime church and among Brazilian spiritualist communities that make ceremonial use of ayahuasca. It suggests that substances such as ayahuasca are very peculiar pharmacological tools whose value needs to be made sense of within specific ecologies of use and care that are not yet easily comprehensible within the biomedical paradigm. The goal is to reveal how the pharmacology of ayahuasca, its rich semiotic worlds, and the thick relational fabric within which it is used, together, produce a uniquely potent and deeply caring, situated efficacy. The healing presented here emerges out of a loose assemblage of empirical, case-by-case assessments within structured networks of support. This gives the ritual space an iterative and reflexive dimension, thereby enabling a form of care that is attentive to the specificity of different situations and contexts. The chapter concludes with reflections on the conceptual challenges biomedical studies of ayahuasca face in making sense of the complex, dynamic, and amplified efficacy of psychedelic-assisted interventions within an epistemology that presumes a radical distinction between the “pharmaceutical” and the “social.” Within such an epistemology, it becomes difficult to account for the specific, situated, and contextual efficacy that healers witness and patients experience. Supporting such a dynamic of care and making it legible within current evidentiary norms—which are standardized according to universal norms—presents a considerable challenge.
9. Ayahuasca as an Addiction Treatment in Catalonia: Cognitive and Cultural Perspectives
Ismael Apud
Ayahuasca arrived in Spain at the end of the 1980s through different alternative therapy centers, spiritual groups, and Brazilian churches. Since then, Spanish people have been connecting through informal psychospiritual networks, interested in using ayahuasca to cope with various psychological and medical problems. One of these is addiction. This chapter is the summary of research conducted in Catalonia and surrounding areas in Spain, focused on addicts recovered through the ritualistic use of ayahuasca. First, I will make a brief presentation of the studies related to ayahuasca and its potential therapeutic effect, including addiction treatment. Next, a ritual healing model that combines cultural and cognitive levels will be proposed, using insights from medical anthropology, cognitive science of religion, neuropsychology, and other interdisciplinary fields. The model emphasizes how the ritual can produce different “memories of the experience,” triggering new biographical narratives and diverse psychological effects. After this, I will make a description of the research methods: a qualitative study of 12 cases and a biographical analysis of their subjective narratives. The study is not an assessment of the efficacy of the treatment but a qualitative analysis that tries to uncover the cognitive and cultural mechanisms that allow ritual healing to achieve its therapeutic goals. Explaining those cases with both cognitive and cultural approaches will help us to see ritual healing in all its complexity, producing a variety of medical and psychological outcomes.
10. Perspectives on Healing and Recovery from Addiction with Ayahuasca-Based Therapy Among Members of an Indigenous Community in Canada
Elena Argento, Rielle Capler, Gerald Thomas, Philippe Lucas, Kenneth W. Tupper
Indigenous populations in Canada and globally experience a disproportionate burden of social and health-related risks and harms due to multigenerational impacts of colonialism, racialized policies, and related trauma. Associated outcomes include elevated rates of mental health and substance use disorders and devastating disconnection from traditions, culture, language, and spirituality. Despite decades of ongoing research and intervention efforts, conventional addiction treatment approaches continue to have only limited success among such vulnerable populations. This chapter elucidates the lived experiences of participants of a research project assessing the impact of ayahuasca-based therapy on addiction and other substance use-related outcomes among members of a rural Indigenous community in Western Canada. Quantitative findings demonstrated that ayahuasca therapy delivered in a ritualized retreat setting led to statistically significant reductions in problematic cocaine use, with some participants reporting complete cessation of drug use at follow-up. Increased connectedness with self, others, nature, and spirit was described as a key element associated with reduced cravings and substance use. This study highlights the therapeutic potential of ayahuasca-based therapy to facilitate deep and sustained healing and recovery from addiction for members of an Indigenous community, including some who had experienced highly traumatic histories and several failed treatment attempts. Given the heterogeneity of Indigenous populations, and distinct vulnerabilities associated with living in rural and remote settings, this study supports calls to advance research tailored to the needs of marginalized populations. Further research should explore how ayahuasca and other psychedelics affect connectedness and other factors that may improve well-being and facilitate recovery from addiction.
11. Ayahuasca as a Healing Tool Along the Continuum of Recovery from Eating Disorders
Adele Lafrance, Marika Renelli, Jenna Fletcher, Natasha Files, Kenneth W. Tupper, Anja Loizaga-Velder
Eating disorders (EDs) are associated with a wide array of comorbid psychological symptoms and conditions. They can have a serious impact on quality of life, as well as contributing to high morbidity and premature mortality. EDs are also among the most challenging mental disorders to treat, and long-term outcome studies show high rates of relapse. For these reasons, new treatments must be explored. This chapter will explore the potential for ayahuasca as a healing tool for EDs via qualitative study of the experiences of participants with both a history of an ED and ceremonial ayahuasca use in various contexts. Positive outcomes will be presented through a biopsychosocial-spiritual lens, as will data from a subset of participants who also engaged in conventional ED treatment in North America. Perceived risks associated with ayahuasca-assisted therapy and recommendations for the integration of ayahuasca in a Western context will also be presented.
12. The Therapeutic Use of Ayahuasca in Grief
Débora González, Adam Andros Aronovich, María Carvalho
This chapter is part of a broader study that aims to prospectively assess the long-term effects of ayahuasca on bereavement. The qualitative reports shown here are from participants who attended workshops at the Temple of the Way of Light while processing grief over the death of a loved one. Several themes emerged: emotional processing, making meaning of the past, reconstructing identities, continuing bonds with the deceased, and finding existential meaning. These psychological processes have been described as mediators in grief adaptation in scientific literature. Adding to this evidence, we also explored the perspectives of four Shipibo onaya healers. This way, we understood that the observed therapeutic effects of ayahuasca cannot be described solely in terms of psychological and intrapersonal dimensions, since they are embedded in a particular ceremonial and ethnomedical context, with many experiences being reported in relation to the participant’s perception of the role of the work of the Shipibo healers and the icaros.
13. Healing at the Intersections between Tradition and Innovation: An Interview with Shipibo Onaya Jorge Ochavano Vasquez
Adam Andros Aronovich, Beatriz Caiuby Labate
Jorge Ochavano Vasquez, also known as Soi, is a Shipibo onaya (“one who knows”: a healer who works with oni, meaning wisdom or knowledge, the Shipibo name for ayahuasca) from the Ucayali River Basin in the Peruvian Amazon. Heir to a long line of Shipibo onayabo, he was initiated into this medical system while growing up in a region of rainforest undergoing rapid globalization and urbanization. Soi belongs to a generation of young Shipibo healers whose practice has been heavily informed and influenced by the increasing interest, attention, and presence of Western ayahuasca seekers. Working regularly in retreat centers that cater to Western clients (including the Temple of the Way of Light as well as his own family center in the native community of Nueva Betania). In this interview, we explore Soi’s perception of illness and well-being as it emerges from the encounter between two worldviews and their related medical systems. Amazonian diagnostic categories such as “daño,” “susto,” or “cupia”—some of the most common complaints among indigenous or mestizo Amazonians—imply a degree of external agency and are usually attributed to sorcery, magic, or disharmonious relationships with the plant, animal, or spirit realms. Yet, the majority of Westerners seeking ayahuasca usually complain of depression, anxiety, posttraumatic symptoms, and a variety of other self-reported experiences that, whether as diagnostic constructs or subjective narratives of affliction, are mostly prevalent in industrialized and individualistic societies. In this interview, we offer the perspective of a young healer, who dialogues with both indigenous etiologies and Western diagnostic constructs, working on the frontline of the controversies surrounding the tension between tradition and innovation, and who has lived experience of the paradoxical nature of “development” in a rapidly Westernizing world.

Kim PC Kuypers (PhD) is affiliated as an Associate Professor with Maastricht University, Faculty of Psychology and Neuroscience where she obtained her PhD in 2003. Her main goal is to understand the neurobiology underlying flexible cognition, empathy and well-being. To accomplish this she uses a psychopharmacological model, to induce (sub)acute and longer lasting effects on aforementioned behavior with psychedelics, and investigate the underlying biology. She also conducts survey research to understand the motives underlying psychedelic use, and the experienced effects, and she develops new paradigms to study cognitive flexibility and empathy in a more ecologically valid way. The survey research gives direction to her experimental research in which she uses the newly developed paradigms. Her research contributes to the understanding of the biological and psychological underpinnings of cognitive and emotional processes linked to well-being.
