The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) states: Dry retching is caused by the rebellion of Stomach Qi. It involves the urge to vomit without anything being expelled, hence it is called dry retching.
The *Seng Shen Fang* (Prescriptions of Monk Shen) for treating Stomach Qi rebellion with dry retching, urge to vomit but nothing coming out, uses the Ginseng Decoction:
Ren Shen (Ginseng Radix et Rhizoma, 2 liang), Gan Jiang (Dried Ginger Rhizome, 4 liang), Ze Xie (Alisma Rhizome, 2 liang), Gui Xin (Cinnamon Twig Heart, 2 liang), Gan Cao (Licorice Root, 2 liang), Fu Ling (Poria, 4 liang), Da Huang (Rhubarb Root and Rhizome, 1 liang).
Take these eight herbs, add eight sheng of water, decoct until three sheng remain. Take eight ge per dose, three times a day.
