Name and classical tradition
Zhongquan, 中泉, is the “spring of the center,” at the center of the dorsum of the wrist, between LI5, Yangxi, and TE4, Yangchi.
The Zhenjiu Dacheng (Great Compendium of Acupuncture and Moxibustion) describes exactly that location, but under another name: “湧泉二穴，在手背腕中，在陽谿陽池中間陷中是穴，灸二七壯，治心痛及腹中諸氣，疼不可忍.” It calls it Yongquan, “gushing spring,” the same name as KI1 on the sole of the foot, and uses it with moxa for heart pain and abdominal pains. The current name, Zhongquan, avoids that confusion and keeps the water of the ancient name.
