The big toe is the starting point for the Liver Channel, which then passes through the foot dorsum and medial malleolus and flows upwards along the leg medial. Proceeding further up around the genitalia, it then passes the lower abdomen, curves around the Stomach and arrives at the Liver and Gallbladder. From here, it rises further through the diaphragm and branches out in the hypochondrial. Continuing further upwards through the throat and eye, it ascends and finally reaches the head vertex, where it joins the Governing Vessel.
It has influences over the above mentioned areas, such as the leg medial, abdomen, hypochondrium, throat or head. It especially has great impact on menstruation, as it help regulating the Blood in the Uterus. Also, it can be used to treat urinary and genital problems as it has many acupuncture points useful for these purposes.
