Ayahuasca for Anxiety Disorders

74 papers and 0 clinical trials exploring ayahuasca as a treatment for anxiety disorders.

Compoundclassic psychedelic

Ayahuasca

Ayahuasca is a botanical decoction combining DMT with MAO-inhibiting harmala alkaloids, producing intense psychedelic effects lasting 3-6 hours. Clinical trials show rapid, large antidepressant effects from a single dose, with a favourable safety profile in controlled settings.

Anxiety Disorders

Anxiety disorders are the most common mental health conditions in the world, yet for primary anxiety (generalised anxiety, social anxiety, panic) the psychedelic evidence is surprisingly thin. The clear front-runner is LSD: MindMed’s MM120 met its Phase 2b endpoint in generalised anxiety disorder and is now in two Phase 3 trials. Most other psychedelic anxiety data comes from cancer and end-of-life distress, a different problem covered on our palliative page, or is measured as a side effect of treating depression.

Brain-body integromics of the ayahuasca experience

This observational study (n=20) of experienced ayahuasca users linked the drug’s subjective effects with changes in blood alkaloids, metabolism and brain network connectivity. The strongest shared patterns involved altered default mode and attention networks alongside lipid-related metabolic signals, suggesting the ayahuasca experience reflects coordinated brain-body changes.

Efficacy and Safety of the Neuroplastogen TSND-201 for the Treatment of PTSD A Randomized Clinical Trial

In a multicentre, double‑blind, placebo‑controlled phase 2 trial of 65 adults with chronic PTSD, once‑weekly oral TSND‑201 produced significantly greater reductions in clinician‑rated PTSD severity (CAPS‑5; LS mean difference 9.64, P = .01) and improvements in self‑reported symptoms, functioning and depression versus placebo. TSND‑201 was generally well tolerated — common adverse events included headache, decreased appetite, nausea, dizziness and transient blood‑pressure increases — supporting its potential as a rapid‑acting, durable treatment for PTSD.

Naturalistic psychedelic use and changes in depressive symptoms

This longitudinal observational study (n=12,345) of U.S. residents found that naturalistic psychedelic use (n=505, 4.1% of participants) was associated with modest increases in depressive symptoms, particularly when occurring in 'risk contexts' characterised by negative mindset and lack of psychological support, with challenging psychedelic experiences mediating this relationship and suggesting that unsupervised psychedelic use may not be generally therapeutic and could worsen depression under certain circumstances.

Intact neurophysiological markers of death denial in long-term ayahuasca users

Using a no‑report MEG visual mismatch response paradigm, the study found that long‑term ayahuasca users report reduced fear of death and greater life satisfaction, but nonetheless retain intact neurophysiological markers of self‑specific death denial at automatic perceptual levels. The neural denial marker correlated with lower self‑reported death acceptance and reduced accessibility of death‑related thoughts, suggesting ayahuasca alters conceptual and affective engagement with death but not unconscious self‑specific denial.

DMT and harmala alkaloids: an exploratory study of oral Acacia based formulations in healthy volunteers

In this open-label exploratory crossover study of nine experienced ayahuasca users, three Acacia‑derived oral formulations delivering DMT plus harmala alkaloids were well tolerated, produced no clinically significant physiological changes, and elicited psychedelic effects rated comparable to (and for ACL‑010 sometimes more beneficial than) traditional ayahuasca. These findings suggest Acacia‑based DMT/harmala formulations are a feasible alternative for future clinical trials, although generalisability is limited by the small sample size and open‑label design.

Exploring the Therapeutic Effects of Psychedelics Administered to Military Veterans in Naturalistic Retreat Settings

Veterans attending naturalistic psilocybin or ayahuasca retreats showed significant improvements across eight mental‑health and reintegration measures, with the largest reductions in depression (PHQ‑9, 29.1%) and PTSD (PCL‑5, 26.1%). Psilocybin retreats produced greater gains on most outcomes while ayahuasca yielded slightly larger PTSD improvement; those with worse baseline symptoms benefited most, with some gender-specific differences.
