《黄帝内经·素问·脉解》
足阳明胃经有所谓寒冷颤栗的症状，是因为农历五月，地支为午，阳明。五月是阳极而生的时候，人体也是一样，阴气加于盛阳之上，故令人寒冷颤栗。
阳明所谓洒洒振寒者，阳明者午也，五月盛阳之阴也，阳盛而阴气加之，故洒洒振寒也。
The so-called symptoms of chills and chills in the foot Yangming stomach meridian are because in the May of the lunar calendar, the earthly branch is noon, Yangming. May is the time when the sun is born, and the human body is the same. Yin qi is added to the strong sun, which makes people feel chills and tremors.
