Banlangen belongs to the category of Chinese medicine. From the perspective of Chinese medicine, Banlangen has certain effects on treating the common cold, meaning it can be used to treat colds. For example, Banlan根 is most commonly used to treat colds, mainly treating wind-heat type colds, and its effectiveness for colds due to wind-cold or summer dampness is relatively poor or non-existent. However, from the perspective of modern medicine, the common cold is often caused by viral infections of the respiratory system, classified as acute upper respiratory infection, which can cause symptoms such as fever, nasal congestion, runny nose, and sore throat. Therefore, a combination of medications is used to improve the clinical symptoms of a cold. Common medications include compound paracetamol and amantadine, Mameimin tablets, etc. Banlangen is generally not used for treatment. (Please follow medical advice when using medication.)
