Preclinical evaluation of baicalein supplementation for the management of SARS-CoV-2 infections

This preclinical study has evaluated the potential of baicalein, an active compound of Scutellaria baicalensis, for the management of COVID-19.

In vitro an inhibition of cellular damage induced by SARS-CoV-2 has been demonstrated after exposure to at least 0.1 µM of baicalein. According to in vivo study, this concentration can be reached by supplementation with 200 mg/kg of crystal form beta of baicalein. Moreover, in vivo, in rats infected with SARS-CoV-2, supplementation with baicalein significantly inhibited the body weight loss, the replication of the virus, and relieved the lesions of lung tissue. At last, baicalein supplementation has been associated with a reduction of LPS-induced lung inflammation and alteration of respiratory function.

In conclusion, in vivo supplementation with baicalein has demonstrated efficiency in the management of SARS-CoV-2 infection as well as in the management of infection-associated symptoms.
