| Commentary: "chen" means the longer you keep the herbs, the more potent they are. There are 6 "chen" herbs in the materia medica: Ban Xia, Chen Pi, Ma Huang, Wu Zhu Yu, Zhi Shi, and Long Du(poisonous, no longer used). Xin Hui Chen Pi is the known for being the best quality. Ginger reduces the toxicity of Ban Xia. The basic processed form is Fa Ban Xia to eliminate dampness and phlegm. The most efficient way to get rid of dampness is to promote urination. Fu Ling promotes urination. Some formulas remove Wu Mei because it's sour and from the stabilize and bind category so it's contra to the purpose of the formula. However, some thinks that Wu Mei is used to gather the phlegm and expel it.[Song] |
