Title
(EN) Prevention and Treatment of SARS-CoV-2 Infection by Mentha piperita and Flos chrysanthemi Extracts alone, and their Combination
Abstract
(EN)

Due to the SARS-CoV-2 pandemic, the development and screening of novel antiviral agents are urgently required. Herein, we developed herbal extracts with promising antiviral activity against SARS-CoV-2. Antiviral effects of Mentha piperita, and Flos chrysanthemi extracts alone, in combination and their fractions were found to decrease viral load. To determine which step of the virus is inhibited by the treatment, the extracts were administered at different time points of treatment, namely prophylactic (Full-time), pre-adsorption (Entry), and post adsorption (Post-entry). Most of the fractions, exhibited high efficacy upon prophylactic administration. The viral load was lower in prophylactic-treated cells than in non-treated cells. Administration of combinations, following 2:1 molar ratio of Mentha piperita, and Flos chrysanthemi significantly reduced the viral load by increasing the Cq values. Ethyl acetate extract of Mentha piperita and hexanes extract of Flos chrysanthemi were found to be most effective at all treatment points.
