Efficacy & Actions

This point belongs to the Hand Shaoyang Sanjiao Meridian. It unblocks the meridians and collaterals, relaxes the sinews and benefits the joints, and dispels wind and relieves pain. It is a commonly used key point for treating upper limb paralysis and arm disorders. First documented in Zhenjiu Jiayijing. "Sanyang" refers to the three yang meridians of the hand (Taiyang, Shaoyang, Yangming); "Luo" means to connect. This point is where qi and blood of the three yang meridians converge and connect – hence the name Sanyangluo (Three Yang Connector). It is also known as "Tongjian."
