Ayahuasca Therapy

Reviewed by the HeyPsych Medical Review Board

Board-certified psychiatrists and mental health professionals

Indications

Primary Indications

Treatment-resistant depressionPost-traumatic stress disorder (PTSD)Substance use disordersAnxiety and existential distressPalliative care and end-of-life concerns

Mechanism

Ayahuasca combines DMT, a potent psychedelic acting on 5-HT2A and other serotonin receptors, with β-carboline MAO inhibitors that render DMT orally active. The brew induces altered states of consciousness characterized by vivid visions, emotional release, and insights into personal narratives. Neurobiologically, ayahuasca increases neuroplasticity markers (e.g., BDNF), modulates the default mode network, and may enhance emotional processing and therapeutic breakthroughs.
