Banlangen is a commonly used proprietary Chinese medicine in clinical practice, which has the effect of clearing away heat and detoxifying toxins, and the medicine is mainly used to treat wind-heat cold and flu diseases. If the patient has a sore throat, sneezing, runny nose, body pain or low fever and other symptoms, Banlangen has a certain therapeutic effect. New coronavirus infection mainly occurs in Wuhan area, Wuhan is relatively humid, cold, so the patient more wind-dampness, cold dampness or dampness-heat stagnation symptoms, the patient is usually yellow tongue or white greasy thick, poor appetite, diarrhea, spleen deficiency and dampness is more common. Lanlangen is mainly clearing heat and detoxification, on the new coronavirus disease, from the evidence on the degree of coincidence is poor, and patients with dampness and heat are generally spleen, dampness, aroma and turbidity, avoid using bitter cold. Therefore, Banlangen has a poorer preventive effect on the new coronavirus, both from the perspective of Chinese medicine and Western medicine. Source: Dr. Yau Lai
