Shamanism as a Clinical Intervention: A Scoping Review

Journal of Restorative Medicine January 1, 2025 Matthew Hicks, Richard Harris 3 citations

Shamanic healing, a practice rooted in transcultural worldviews involving interaction with the spirit world, shows potential benefits and a low risk of harm when used as a clinical intervention. A review of medical literature found sixteen relevant publications, including one clinical trial, two case series, and ten case reports. The authors conclude that shamanic healing is feasible to investigate further, though more research is needed to clarify its benefits.

Low-income group psilocybin assisted therapy for depression: An Oregon feasibility study

Journal of Psychedelic Studies February 12, 2026 Matthew Hicks, Olivia Hicks, Ryan Bradley et al. 2 citations

Group psilocybin therapy is feasible for low-income adults with depression in Oregon's regulated psilocybin program. In an open-label study, 20 participants began treatment and 19 completed two psilocybin administration sessions one week apart, with preparation and integration sessions online. No severe adverse events occurred; participants rated satisfaction 4.8 out of 5, reporting moderate to high benefit and no harm. Exploratory outcomes showed a significant decrease in Hamilton Depression scores with a strong effect size (Cohen's d = 1.89), and all eight domains of the PROMIS-29 significantly improved with effect sizes from 0.667 to 1.774. Further research with comparator groups is warranted.
