Trauma, Autoimmunity, and the Emerging Science of Psychedelic Therapy – With Dr. Will Van Derveer

In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz interviews integrative psychiatrist Dr. Will Van Derveer about the often-misunderstood field psychedelic-assisted therapy, and how it may be an effective tool for trauma healing and even deeper root cause work. Emphasizing the importance of safety, screening, and in-person clinical support, Dr. Van Derveer discusses the myths and misconceptions about these therapies, how they are very different from recreational drug use, and why they may offer new hope for people dealing with treatment-resistant PTSD depression, and more.

Together, they explore how trauma can shape immune function, inflammation, and even autoimmune conditions. They also discuss EMDR, somatic work, spiritual disconnection, mental health stigma, and the nuanced differences between MDMA, psilocybin, and ketamine in therapeutic settings. While this field is rapidly evolving, he emphasizes that these therapies are not a DIY solution and can be unpredictable or even destabilizing without proper clinical guidance.

What you’ll learn in this episode:
✅Why psychedelic-assisted therapy is not the same as recreational drug use. Dr. Van Derveer explains that these therapies are used in highly specific clinical settings, with careful screening, preparation, dosing, and follow-up. He also shares why trying to replicate these experiences on your own can be risky, unpredictable, and potentially dangerous, highlighting the critical role of trained practitioners in creating a therapeutic (not recreational) environment.
✅How unresolved trauma may become an overlooked root cause in chronic illness. Trauma can affect inflammation, immune function, the HPA-axis, and even autoimmune conditions like Hashimoto’s. This is especially relevant for people with thyroid issues, who may have focused only on the physical side of healing while missing an important emotional piece.
✅Why talk therapy alone may not always be enough. Some people can clearly identify their patterns, understand their trauma intellectually, and still feel stuck. Dr. Van Derveer shares why layered or preverbal trauma may require different approaches, including EMDR, somatic therapies, or psychedelic-assisted therapy, to help people access healing beyond words.
✅The key differences between MDMA, psilocybin, and ketamine in therapeutic settings. Each therapy has a distinct mechanism, duration, and use case. Dr. Van Derveer breaks down how MDMA is being studied for PTSD, psilocybin for depression, and ketamine for rapid symptom relief, and why clinical MDMA and psilocybin therapy may offer longer-lasting benefits.
✅Why safety, preparation, and the right practitioner are everything. Dr. Van Derveer explains how improper dosing, lack of preparation, or the wrong environment can overwhelm the nervous system – while skilled guidance can support meaningful and lasting healing.
✅How trauma healing may improve thyroid antibodies and autoimmune flares. While psychedelic-assisted therapy is not a magic bullet, Dr. Van Derveer has observed improvements not only in mental health symptoms, but also in markers like thyroid antibodies and autoimmune flare frequency, reinforcing the deep connection between emotional and immune health.

Tune in to learn more about trauma, safety, and the evolving role of psychedelic-assisted therapy in root-cause healing.
