Medicine originates from instinctive behavior and lives of animals are maintained by self-healing. We put forward the somatic stimulation as acupuncture from the perspective of biological evolution in that acupuncture is related to specific structures on the surface of human body:Skin stressor may induce keratinocytes to secrete glucocorticoid and other endocrine substances, to generate diffused bioeffects; Somatic inputs may stimulate pain control gate to produce analgesia; Somato-visceral afferents may integrate at different levels and activate multiple functional regulation.
