Xiao Yao San is indicated for the pattern of liver constraint, blood deficiency, and spleen weakness, characterized by rib-side pain, headache, dizziness, dry mouth, dry throat, mental fatigue, reduced food intake, menstrual irregularities, distending pain of the breasts, and a wiry, deficient pulse. |
【Pathogenesis】 |
The liver likes to govern free activity and dislikes inhibition and constraint. It stores the blood and belongs to yin in form but yang in function. When emotion is inhibited, the liver fails to free and soften the form, which may result in liver constraint and blood deficiency. Since “the foot jueyin liver channel distributes along the rib-side, circulates behind the throat… connects with the eyes, ascends to the forehead, and joins the du mai at the top of the head,” liver constraint and blood deficiency may result in rib-side pain, headache, and dizziness. When the liver constraint transforms into fire, a dry mouth and dry throat may result. Liver disease tends to transmit to the spleen, which may result in mental fatigue and reduced food intake due to the spleen and stomach weakness. The liver stores the blood and governs the free flow of qi. When women suffer from liver constraint, blood deficiency, and spleen weakness they may suffer menstrual irregularities and distending pain of the breasts. The treatment is to soothe the liver, resolve constraint, nourish blood, and fortify the spleen. |
