  16. Both Zhi Ban Xia and Rz. Zingiberis Recens Sheng Jiang harmonize the Stomach, settle nausea and alleviate cough. Zhi Ban Xia dries Dampness and disperses Phlegm and thin mucus to settle nausea and dry Dampness and transform Phlegm to treat cough. Sheng Jiang warms the Stomach and awakens the Spleen in order to harmonize the Stomach and settle nausea and warms the Lungs and transforms thin mucus to stop cough.
