Dispersing can remove stagnation, by adding ingredients such as Fresh Ginger Rhizome and tangerine peel. Dispersing means to scatter, and stagnation refers to the illness of blockage. For symptoms such as chest distension, vomiting, and nausea, the "Two Old Ingredients Decoction" (composed of aged tangerine peel, Pinellia, Poria, and Liquorice Root) can be used to regulate qi and disperse stagnation. If there is phlegm-fluid retention in the stomach, "Muskmelon Base Powder" and other emetic therapies can also be used, which is another method of dispersing.
