Efficacy & Actions
This is an extraordinary point located on both sides of the spine, 0.5 cun lateral to the depression below each spinous process from the 1st thoracic to the 5th lumbar vertebra – 34 points in total (17 on each side). It regulates zang-fu functions, unblocks the meridians and collaterals, and balances yin and yang. It is a commonly used key point for treating spinal and internal organ disorders. First documented in the Zhouhou Beiji Fang (Emergency Prescriptions from the Elbow), and later popularized by the renowned physician Hua Tuo – hence the name "Hua Tuo Jiaji." "Jia" means to flank or be beside; "Ji" refers to the spine. Located on both sides of the spine – hence the name Jiaji (Spine Side Points). Jiaji points are commonly used in clinical practice. According to the corresponding vertebral segments, they treat internal organ and limb disorders in the related areas. They are easy to locate, effective, and particularly beneficial for spine-related disorders and zang-fu dysfunction.
Contraindications
Located on both sides of the spine – needling depth and angle should be carefully controlled, generally 0.5–1 cun vertically or oblique toward the spine, avoiding excessive depth to prevent injury to internal organs or the spinal cord. Moxibustion is permissible. Use with caution in pregnant women.
