Several kinds of cough
It is always stir-baked with honey for use. It has the main action of resolving phlegm and stopping cough, so it is indicated for cough caused by different reasons. The property and actions of Kuan Dong Hua are similar to Zi Wan, but the latter is good at resolving phlegm and the former is good at stopping cough, so they are mutually reinforced. For cough and dyspnea due to wind-cold and phlegm-fluid retention, it is often combined with wind-cold-dispersing and phlegm-dispelling and cough-stopping herbs. For instance, it is combined with Zi Wan, Xi Xin, Ban Xia, Sheng Jiang and Ma Huang and so on, in She Gan Ma Huang Tang, from Jin Kui Yao Lue. For cough predominant in heat, it is combined with lung-clearing and phlegm-resolving herbs, such as Zhi Mu, Sang Bai Pi and Bei Mu and so on. For persistent cough due to lung qi deficiency, it is combined with lung-qi-tonifying herbs, such as Ren Shen, Shan Yao and Huang Qi, etc. For dryness cough due to yin deficiency, it is combined with yin-nourishing and lung-moistening herbs to stop cough, such as Sha Shen and Mai Dong, etc.
