Banlangen Injection

Banlangen Injection is a traditional Chinese medicine (TCM) injectable product derived from the root of *Isatis indigotica* (Isatis root). Manufactured by Sichuan Sunnyhope Pharmaceutical, it is a sterile aqueous extract used for its heat-clearing, detoxifying, and blood-cooling properties according to TCM principles. The injection is primarily indicated for the treatment of viral infections, including influenza, upper respiratory tract infections, mumps, and sore throat. Its pharmacological profile is attributed to a complex mixture of bioactive compounds such as alkaloids, organic acids, and polysaccharides, which collectively exhibit broad-spectrum antiviral and anti-inflammatory activities.
