The effects of acupuncture stimulation on the Chu-Chih (LI-11) and Ho-Ku (LI-4) loci on both thermoregulatory function and analgesic activity were assessed in normal adults. Stimulation of Chu-Chih and Ho-Ku each produced both hypothermia and analgesia. The hypothermia was brought about by decreased metabolic heat production and cutaneous vasodilatation (as estimated by an increase in cutaneous temperature). The analgesic effect was shown by an increase in the latency to palm lift in the hot plate test. Thus, the data indicate that stimulation of acupuncture loci Chu-Chih and Ho-Ku is an ideal treatment for both the fever and painful syndromes.
