Efficacy & Actions

This point belongs to the Foot Taiyang Bladder Meridian. It unblocks the Bladder, regulates the lower jiao, regulates qi and unblocks the fu-organ. It is a commonly used key point for treating urinary and digestive system disorders. First documented in Zhenjiu Jiayijing. "Bao" refers to the Bladder or uterus; "Huang" refers to the membrane. Located in the sacral region, this point is where bladder qi is transported – hence the name Baohuang (Bladder Membrane).
