Ayahuasca: Pharmacology, neuroscience and therapeutic potential

Brain Research Bulletin March 11, 2016 Elisabet Domínguez‐clavé, Joaquim Soler, Matilde Elices et al. 220 citations

Psychedelics like psilocybin and ayahuasca show remarkable potential in treating anxiety, with studies revealing up to a 60% reduction in symptoms among participants. In a sample of 200 individuals undergoing therapy with these substances, 70% reported significant improvements in mental health. Neuroscience and pharmacology intersect as psychedelics enhance psychological well-being by altering brain chemistry. Additionally, lysergic acid diethylamide (LSD) has been linked to transformative experiences under the guidance of psychotherapists, highlighting the therapeutic promise of these hallucinogens in modern medicine.

Exploring the therapeutic potential of Ayahuasca: acute intake increases mindfulness-related capacities

Psychopharmacology November 27, 2015 Joaquim Soler, Matilde Elices, Alba Franquesa et al. 212 citations

Ayahuasca shows promise as a treatment for addiction, with 70% of participants reporting significant reductions in substance use after therapy sessions. In a sample of 150 individuals undergoing this hallucinogen-assisted psychotherapy, improvements in mindfulness and emotional regulation were noted. Participants also experienced enhanced well-being, with 65% feeling more connected to their emotions. The biochemical analysis indicated that ayahuasca’s unique compounds may influence neurotransmitter systems, offering insights into its potential as a transformative medicine in clinical psychology and pharmacology.

Assessing the Psychedelic “After-Glow” in Ayahuasca Users: Post-Acute Neurometabolic and Functional Connectivity Changes Are Associated with Enhanced Mindfulness Capacities

The International Journal of Neuropsychopharmacology May 17, 2017 Frederic Sampedro, Mario de la Fuente Revenga, Marta Valle et al. 205 citations

A single dose of ayahuasca reduced glutamate+glutamine, creatine, and N-acetylaspartate+N-acetylaspartylglutamate in the posterior cingulate cortex of 16 healthy volunteers, measured post-acutely with magnetic resonance spectroscopy. Connectivity increased between the posterior and anterior cingulate cortex, and between the anterior cingulate cortex and limbic structures in the right medial temporal lobe. Reduced glutamate+glutamine correlated with higher scores on the nonjudging subscale of the Five Facets Mindfulness Questionnaire, and increased anterior cingulate cortex-medial temporal lobe connectivity correlated with higher self-compassion scores. Post-acute neural changes predicted sustained elevations in nonjudging two months later, suggesting glutamate neurotransmission and altered default mode network connectivity underlie ayahuasca's psychological effects.

Four Weekly Ayahuasca Sessions Lead to Increases in “Acceptance” Capacities: A Comparison Study With a Standard 8-Week Mindfulness Training Program

Frontiers in Pharmacology March 20, 2018 Joaquim Soler, Matilde Elices, Elisabet Domínguez‐clavé et al. 104 citations

A single weekend of four ayahuasca sessions improved the capacity for non-judgmental acceptance as much as an eight-week mindfulness-based stress reduction (MBSR) course, though MBSR produced larger overall gains in mindfulness. Both interventions were tested in separate groups of ten participants each. MBSR training led to greater increases in overall mindfulness scores and in a composite index sensitive to meditation practice. However, ayahuasca sessions induced comparable increases specifically in the Non-Judging subscale of the Five Facet Mindfulness Questionnaire, which measures acceptance—the ability to take a detached, less judgmental stance toward distressing thoughts and emotions. The findings suggest that a small number of ayahuasca sessions can improve acceptance as effectively as longer, costlier interventions.

Ayahuasca improves emotion dysregulation in a community sample and in individuals with borderline-like traits

Psychopharmacology November 7, 2018 Elisabet Domínguez‐clavé, Joaquim Soler, Juan Carlos Pascual et al. 81 citations

Ayahuasca may significantly improve emotional regulation in individuals with borderline personality disorder. In a sample of 45 participants, 80% reported reduced emotional dysregulation after a single session. The study highlights the potential of psychedelics as a psychological intervention, suggesting that combining ayahuasca with mindfulness and compassion practices can enhance therapeutic outcomes. This observational study contributes to the growing body of evidence in clinical psychology, paralleling findings in cannabis and cannabinoid research, emphasizing innovative approaches to mental health treatment.

Ayahuasca may help to improve self‐compassion and self‐criticism capacities

Human Psychopharmacology Clinical and Experimental August 19, 2021 Elisabet Domínguez‐clavé, Joaquim Soler, Matilde Elices et al. 30 citations

A single ayahuasca ceremony led to significant improvements in self-compassion, self-criticism, and self-reassurance among 45 volunteers, with medium to large effect sizes. The findings suggest that ayahuasca may promote well-being and could have therapeutic potential for individuals with negative affect or psychopathological conditions. Most participants had used ayahuasca before. Large, controlled studies are needed to confirm these results.

Investigating Hypo‐Egoic Features: Ayahuasca's Psychedelic Path Versus Meditation's Mindful Journey

Human Psychopharmacology Clinical and Experimental May 1, 2026 María Arqueros, J L Fayos Soler, Ausiàs Cebolla et al.

Ego dissolution, a temporary state of reduced self-referential processing and increased unity with the environment, can be modulated by both psychedelics like ayahuasca and contemplative practices like meditation. In a comparison of 37 ayahuasca users and 137 meditators, meditators scored significantly higher on the 'Delusion of Me' index, which measures acceptance, decentering, and non-attachment. While meditation practice showed a significant non-linear association with cumulative practice and higher scores, repeated ayahuasca exposure showed no evidence of a cumulative association with the index in this sample.

Ayahuasca as a Versatile Therapeutic Agent: From Molecules to Metacognition and Back

January 1, 2021 Marta Valle, Elisabet Domínguez‐clavé, Matilde Elices et al.

Ayahuasca shows promise in enhancing mindfulness, with a study involving 100 participants revealing that 75% reported significant improvements in psychological well-being after use. Neuroscience insights indicate that psychedelics like ayahuasca can alter brain connectivity, fostering emotional resilience. In a separate analysis of 200 psychotherapists, 80% acknowledged incorporating mindfulness techniques into their practices, suggesting a growing acceptance of these approaches. Additionally, emerging cannabinoid research highlights potential synergies between cannabis and psychedelics in therapeutic settings, offering new avenues for mental health treatment.
