《黄帝内经·灵枢·论疾诊尺》
手臂的中部发热，标志着腰腹部有热象；肘后皮肤粗糙，而且以下三四寸处发热，标志着肠道中有寄生虫存在。
臂中独热者，腰腹热；肘后麤，以下三四寸热者，肠中有虫。
When the skin in the middle of the upper arm is hot to the touch, it indicates that the abdomen and waist area is experiencing heat. When the skin behind the elbow is rough and the area 3-4 inches below is hot to the touch, it indicates the presence of parasites in the intestines.
