Langenlianqiao

Langenlianqiao (LGLQ) is a Traditional Chinese Medicine (TCM) herbal formulation composed primarily of Isatidis Root (*Radix Isatidis*) and Forsythia (*Fructus Forsythiae*). Developed as an oral liquid, it is being investigated for the treatment of mild COVID-19 and other viral respiratory infections. The formulation is designed to leverage the traditional heat-clearing and detoxifying properties of its constituent herbs to provide antiviral and anti-inflammatory effects. Clinical research, including studies led by Central South University, has evaluated its efficacy in managing symptoms such as fatigue and fever, positioning it as a potential alternative or complementary treatment option to established TCM therapies like Lianhua Qingwen.
