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:

Take these eight herbs, add eight sheng of water, decoct until three sheng remain. Take eight ge per dose, three times a day.

Zhu Yu (Evodia Fruit, half sheng), Da Zao (Jujube Fruit, 10 pieces), Ren Shen (Ginseng Radix et Rhizoma, 3 liang), Sheng Jiang (Fresh Ginger Rhizome, 6 liang).
Take these four herbs, add six sheng of water, decoct until two sheng five ge remain. Take three times a day.

Ju Pi (Citrus Reticulata Peel, 4 liang), Sheng Jiang (Fresh Ginger Rhizome, 6 liang, sliced).
