Blue Scutellaria Oral Liquid can treat cough. This drug is a purely proprietary Chinese medicine preparation, mainly composed of Scutellaria baicalensis, Gardenia jasminoides, Panax quinquefolium and Fatty sea, which can play the role of clearing heat and detoxifying the toxins, and relieving the swelling of the throat. It can treat the symptoms of acute pharyngitis such as sore throat, dry throat and burning sensation in the throat caused by lung and stomach heat. If the cough is caused by this kind of reason, it can be used to treat it, but if it is caused by other reasons, the therapeutic effect is not very good. In the case of dry cough, no phlegm and severe cough, it is necessary to cooperate with other cough medicines, such as compound licorice combination and dextromethorphan granules, etc. When bacterial infection is caused, it is also necessary to cooperate with antibacterial drugs to actively treat it, so that it can play a role in relieving cough, but the effect of using this medicine to simply relieve cough is not very good.
