Gynecological diseases are mainly caused by impairment of the thoroughfare and conception vessels. So regulating the thoroughfare and conception vessels is one of the basic treatments for gynecological diseases. However,in the past dynasties, the treatment of gynecological disease usually focused on the treatment of the heart, liver,kidney, spleen and stomach, though the impairment of the thoroughfare and conception vessels is emphasized. This is due to the fact that qi, blood, essence and fluid in the thoroughfare and conception vessels all come from the heart, liver, kidney and spleen. 

Obviously the kidney,liver, spleen and stomach meridians are closely related to the thoroughfare and conception vessels. That is why the treatment of the kidney, liver, spleen and stomach is effective in regulating the thoroughfare and conception vessels. As to the relation of drugs with the meridians,some of the drugs working on the kidney, liver, spleen and stomach meridians also act on the thoroughfare and conception vessels, especially the drugs working on the liver and kidney meridians. That is why doctors in the past dynasties usually used drugs working on the liver and kidney meridians to treat the disorders of the thoroughfare and conception vessels. 

Regulating the thoroughfare vessel, stabilizing the thoroughfare vessel, strengthening the thoroughfare vessel and warming the thoroughfare vessel are the therapeutic methods for regulating the thorough-fare and conception vessels developed by Zhang Xichun in the early 20th century based on the characteristics of gynecology.
