Biofield therapies show their clearest signal not as curative medicine, but as low-risk supportive care for stress, anxiety, pain, burnout, and oncology-related symptom burden, while sham-controlled null findings and retracted evidence sharply limit certainty. The full SAIMSARA evidence map is worth reading because it separates plausible symptom-focused signals from weak, heterogeneous, non-replicable, or overstated claims across Reiki, Healing Touch, Johrei, distant healing, and laboratory biofield models.

Abstract: To synthesize evidence from experimental and clinical studies regarding the efficacy and mechanisms of biofield therapy on physiological markers, psychological symptoms, and biological substrates. The review uses 45 references and builds its evidence map from 31 original studies with 17375 total participants (topic-deduplicated ΣN). Across diverse clinical and laboratory contexts, biofield therapies were most consistently associated with improvements in psychological symptoms, pain, and stress-related wellbeing, with supporting neurophysiological signals such as alpha-wave modulation and HRV changes. Signals were strongest for Reiki and distant energy approaches in anxiety, burnout, and supportive oncology care, while dermatologic applications such as wart treatment showed no advantage over sham. Preclinical work suggests plausible biological correlates, including extracellular-matrix and cancer-cell pathway changes, but findings remain heterogeneous and at times non-replicable. These observations indicate a possible role for biofield interventions as low-risk adjuncts in symptom-focused supportive care, though they do not establish definitive efficacy. Future work should prioritize adequately powered, sham-controlled trials with standardized reporting and longer follow-up to clarify which modalities, doses, and populations yield durable benefit.
