Efficacy & Actions

This point belongs to the Foot Taiyang Bladder Meridian. It tonifies the kidney and secures essence, strengthens the lumbar region and spine, unblocks the water passages, and regulates the lower jiao. It is a commonly used key point for treating kidney deficiency and urogenital disorders. First documented in Zhenjiu Jiayijing. "Zhi" refers to the will or ambition – the kidney stores the zhi; "Shi" means chamber or residence. Located in the lumbar region, this point is where the kidney's will resides – hence the name Zhishi (Will Chamber). It is also known as "Jinggong" (Essence Palace).

Contraindications

Located in the lumbar region, needling should not be too deep – generally 0.8–1.2 cun vertically to avoid injury to internal organs. Moxibustion is permissible and is especially suitable for tonifying the kidney.
