bubble_chart Location

Riyue (GB24) acupoint
(quoted from Riyue (GB24) acupoint)

In the hypochondriac region, directly below nipple, in the depression of seventh intercostal space, 4 cun lateral to the abdominal midline.

• Zhenjiu Jiayi Jing: "1.5 cun below Qimen (LR14)";
• Suwen-Qifu Lun Wang Bing's note: "At the end of third rib, 2.5 cun lateral to xiphoid process, directly above nipples." This places it in seventh intercostal space, 3.5 cun lateral to the midline. However, since nipple is often located at fifth rib, Riyue (GB 24) is correspondingly moved downward to the lower edge of eighth rib, at the junction of costal margin and the lateral border of rectus abdominis muscle.
• Xunjing Kaoxue Bian: "Level with Zhongwan (CV12)." Pang Anshi's Shanghan Zongbing Lun and others locate Qimen (LR14) at the lower edge of costal margin, and Riyue (GB24) is then located 0.5 cun below Qimen (LR14) (as in Beiji Qianjin Yaofang: "0.5 cun below Qimen (LR14)").
