It is fragrant, pungent and warm but not dry. It is good at dispersing and resolving dampness from upper and middle energizer. For the early stage of damp-warm disease manifested as chest stuffiness and no feeling of hungry, it is usually combined with the lung-ventilating and dampness-draining herbs. For instance it is combined with Xing Ren and Yi Yi Ren in San Ren Tang from Wen Bing Tiao Bian. For syndrome of preponderance of heat over damp, it is usually combined with the heat-clearing and dampness-draining herbs such as Huang Qin and Hua Shi.

C. Vomiting
