Efficacy & Actions

This point belongs to the Foot Taiyang Bladder Meridian and is the Back Transporting Point where qi of the Qi Sea is transported to the back. It tonifies the primordial qi, regulates the lower jiao, strengthens the lumbar region and kidneys, regulates menstruation and relieves pain. It is a commonly used point for treating lumbosacral and urogenital disorders. First documented in Zhenjiu Jiayijing. "Qihai" refers to the Qihai point below the umbilicus, where primordial qi gathers; "Shu" means point of transport. This point corresponds to Qihai (RN-6) of the Conception Vessel and is where primordial qi is transported to the back – hence the name Qihaishu (Qi Sea Shu).
