Baliao points correspond anatomically to the sacral nerve posterior branches, and stimulation may modulate the neuro-immune-endocrine network, suppress pro-inflammatory cytokines (e.g., IL-6 and TNF-α), and enhance β-endorphin secretion for analgesia.[12] Ashi points directly target injured areas, improving microcirculation and hematoma resolution. This evidence concerns the gene IL6 and hematoma.
