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

Ayahuasca, a psychedelic brew, alters brain chemistry and connectivity in ways that may explain its lasting psychological effects. The findings point to glutamate neurotransmission playing a role in how psychedelics work in humans. Neurometabolic changes in the posterior cingulate cortex, a hub of the default mode network, along with increased connectivity between the anterior cingulate cortex and medial temporal lobe structures involved in emotion and memory, likely underlie the post-acute psychological effects of ayahuasca.

Therapeutic Use of LSD in Psychiatry: A Systematic Review of Randomized-Controlled Clinical Trials

Frontiers in Psychiatry January 21, 2020 Juan José Fuentes, Francina Fonseca, Matilde Elices et al. 176 citations

A systematic review of controlled and randomized clinical trials evaluated the therapeutic potential of lysergic acid diethylamide (LSD) in psychiatry. Following PRISMA guidelines, 11 randomized-controlled trials involving 567 patients who received LSD doses from 20 to 800 mcg were identified. Despite heterogeneous study designs, positive results emerged, particularly for reducing psychiatric symptoms in alcoholism. Many authors reported significant short-term improvements, though some studies found long-term outcomes homogenized between LSD and control groups. The evidence is strongest for LSD's use in treating alcoholism, but the review notes that most older studies did not meet contemporary standards and that new, properly designed double-blind trials are needed.

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.

GH001 vs Placebo in Patients With Treatment-Resistant Depression

JAMA Psychiatry March 25, 2026 Wiesław Jerzy Cubała, Malek Bajbouj, Michael Bauer et al. 3 citations

A single day of treatment with an inhaled synthetic formulation of mebufotenin (GH001) significantly reduced depression symptoms in adults with treatment-resistant depression compared to placebo. In a randomized, double-blind trial of 81 patients, those receiving up to three escalating doses of GH001 showed an average 15.5-point greater improvement on the Montgomery-Åsberg Depression Rating Scale by day 8 than those on placebo. Remission rates were 57.5% for GH001 and 0% for placebo. No severe or serious adverse events occurred. The findings suggest GH001 may be a rapid-acting, well-tolerated treatment option for treatment-resistant depression.

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.
