Repetitive Electroacupuncture Attenuates Cold-Induced Hypertension through Enkephalin in the Rostral Ventral Lateral Medulla

Approximately one in three adults has high blood pressure (BP) worldwide. Hypertension and its consequences, such as stroke and heart attacks, are enormous public health problems1.
