The notification stipulates that during the epidemic period, designated hospitals for the treatment of COVID-19 in Guangdong Province are allowed to directly dispense and use the Toujie Quwen Granules according to clinical needs, without the need to submit a dispensing application to the Guangdong Provincial Drug Administration. For non-designated hospitals that apply for dispensing and use of the Toujie Quwen Granules, the Guangdong Provincial Drug Administration will give priority approval, and the dispensed medical institutions can directly apply to the entrusted manufacturing enterprise, Guangdong Yifang Pharmaceutical Co., Ltd., for delivery.

Toujie Quwen Granules is a clinical prescription based on the experience of Tan Xinghua, the chief physician of traditional Chinese medicine department at Guangzhou Eighth People's Hospital. Guided by the theory of febrile diseases, this prescription was formulated to treat COVID-19. The principles of traditional Chinese medicine used in its treatment are "clearing heat and detoxifying, dispelling wind and releasing the exterior, and nourishing qi and yin." In clinical applications, "Pneumonia No. 1 Formula" was used to treat 50 confirmed cases of mild COVID-19. After one week of clinical observation, all patients' body temperatures returned to normal, 50% of patients' cough symptoms disappeared, and none of the patients progressed to severe cases.

There are many varieties of Indigo naturalis available for sale in different regions of China, and they come from various plant sources. The main plant sources includeStrobilanthes cusia (a member of the Acanthaceae family), Isatis indigotica (a member of the Brassicaceae family, also known as Isatis tinctoria or daqingye), Isatis indigotica fortunei (also known as daqing), Polygonum tinctorium (a member of the Polygonaceae family, also known as indigo plant), and Indigofera tinctoria (a member of the Fabaceae family).
