Hanxia Houpu Tang is a traditional Chinese medicine formula from “The Essentials of the Golden Chamber”, which contains Hanxia (半夏) to resolve phlegm and disperse lumps, Poria (茯苓) to seep away dampness and fortify the spleen, Ginger (生姜) for pungent warmth and dispersal of lumps and to harmonize the stomach and stop vomiting, Sue Ye (苏葉) to regulate the lungs and soothe the liver, and Huperzia (厚朴) for lowering the qi and removing fullness (to enable the qi to move downward to reduce distension). The combination of the above herbs is effective in moving qi and dispersing lumps (smoothing the qi flow in the body to dissolve lumps), and lowering rebelliousness and resolving phlegm (correcting rebellious qi flow to remove phlegm from the body).
