SARS-CoV-2 omicron variants are susceptible in vitro to Artemisia annua hot water extracts.

ABSTRACT:

Ethnopharmacological relevance

Artemisia annua L. has >2000 yr of history in treating fever a symptom common to many infectious diseases including viruses. The plant is widely used as a tea infusion in many areas of the globe to thwart many infectious diseases.

Aim of the study

The SARS-CoV-2 (COVID-19) virus continues to infect millions while rapidly evolving new variants that are more transmissible and evade vaccine-elicited antibodies, e.g., omicron and its subvariants. Having shown potency against all previously tested variants, A. annua L. extracts were further tested against highly infectious omicron and its recent subvariants.

Materials and methods

Using Vero E6 cells, we measured the in vitro efficacy (IC₅₀) of stored (frozen) dried-leaf hot-water A
