Stomach Heart-shen disturbance

Mai Ya, Shen Qu and Zhi Gan Cao all enter the Spleen meridian. Mai Ya and Shen Qu are able to aid digestion and sweet Zhi Gan Cao can tonify the Spleen. In a formula for treating Liver-Yang ascending and Liver-wind disturbance, they are used to protect the Stomach from heavy mineral substances and cold herbs. They are also used as corrective assistants to moderate the conflict between the minerals in the formula and the Stomach-Qi. This is because, when the heavy minerals descend the Liver-Yang and sedate the Heart-shen, they can descend the rebellious Qi of the Stomach as well. On the other hand, when the action of minerals is too strong and too quick, it may suppress the Stomach-Qi.
