Efficacy & Actions
This point belongs to the Governor Vessel (Du Mai) and is located at the sacral hiatus. It strengthens the lumbar region and tonifies the kidney, unblocks the meridians and collaterals, regulates the lower jiao, and regulates menstruation and stops leukorrhea. It is a commonly used key point for treating lumbosacral and anorectal disorders. First documented in Zhenjiu Jiayijing. "Yao" refers to the lumbar region; "Shu" means point of transport. Located in the lower lumbar region, this point is where lumbosacral meridian qi is transported – hence the name Yaoshu (Lumbar Shu). It is also known as "Yaohu," "Suikong," and "Suishu."
Contraindications
Located in the sacral bony cleft – needling depth should be carefully controlled, generally 0.5–1 cun vertically, avoiding excessive depth to prevent injury to the dural sac. Moxibustion is permissible.
