Ayahuasca: A Neurological and Physiological Perspective on an Ancient Medicine
How a Gunny Sargeant with Treatment Resistant PTSD Did the Work with Ayahuasca
The Science of Ayahuasca: Miguel’s Story and the Three Worlds of Healing
PTSD, anxiety, and emotional trauma don’t just affect the mind—they are imprinted in the nervous system. Many of us are stuck in cycles of stress, fear, or emotional numbness that traditional therapies struggle to resolve.
Ayahuasca has been used for centuries for healing, and modern research now confirms its effects on **neuroplasticity, emotional processing, and nervous system regulation.**
Miguel’s Story: A Veteran’s Journey Through Ayahuasca Healing
For seven years, Gunnery Sergeant Miguel, a decorated Native veteran, suffered from **complex PTSD, severe agoraphobia, and suicidal ideation.** Therapy and medication didn’t help. He had **lost his ability to sleep, step into public spaces, or escape the war inside him.**
Ayahuasca took him through **three stages of healing**—the Underworld, Middle World, and Upper World—each with distinct **scientific and neurological effects** that helped him break free.
1️⃣ **The Underworld – Trauma Processing & Nervous System Reset**
- **Amygdala activation & prefrontal cortex synchronization** allowed trauma to be processed without overwhelm.
- **DMT & serotonin flooded his brain, increasing neuroplasticity and BDNF** to create new neural pathways.
- **The Default Mode Network (DMN) quieted,** reducing PTSD-related hypervigilance and intrusive thoughts.
2️⃣ **The Middle World – Ancestral Visions & Cognitive Reintegration**
- **Theta & Gamma brainwave increases** unlocked subconscious healing and deep insight.
- Miguel saw **his ancestors and the Medicine Wheel**, an ancient system of balance and transformation, giving him a new path forward.
3️⃣ **The Upper World – Ego Dissolution & True Healing**
- **The DMN reset, serotonin & oxytocin increased,** allowing deep self-forgiveness.
- **His nervous system shifted permanently** from survival mode to healing.
**Life After Ayahuasca**
- **For the first time in seven years, Miguel slept through the night.**
- **He walked into a grocery store without fear.**
- **He found purpose in sharing the Medicine Wheel with other Native veterans.**
Science now confirms what indigenous traditions have known for centuries—Ayahuasca creates **real, lasting neurological change** by shifting the nervous system, rewiring trauma, and restoring emotional balance.
**Healing isn’t about forgetting the past—it’s about breaking free from cycles that keep us stuck.**
