Bioactive compounds from Huashi Baidu decoction possess both antiviral and anti-inflammatory effects against COVID-19

Significance Huashi Baidu decoction (Q-14), a famous traditional Chinese medicine decoction for COVID-19, has good effects on SARS-CoV-2 RNA clearance, promoting lung lesion opacity absorption, reducing inflammation, and ameliorating flu-like symptoms based on a series of clinical trials, having potent antiviral and anti-inflammatory effects. However, due to the lack of systematic and in-depth research, little significant progress has been made in the study of TCMT-NDRD of HBF for COVID-19 management. Therefore, the aim of the current study was to identify key antiviral and anti-inflammatory bioactive compounds from HBF based on an integrative pharmacological strategy. These findings will greatly stimulate the traditional Chinese medicine theory-driven natural drug discovery against COVID-19 and promote the modern research of Chinese medicine.
