The component study on LHQW also showed that bioactive ingredients such as quercetin, naringenin, β-sitosterol, luteolin, and stigmasterol may target on regulating androgen receptor (AR), myeloperoxidase (MPO), epidermal growth factor receptor (EGFR), insulin and aryl hydrocarbon receptor (AHR) gene expression against COVID-19 [39]. The gene discussed is MPO; the disease is COVID-19.
