Inhibitory effects of specific combination of natural compounds against SARS-CoV-2 and its Alpha, Beta, Gamma, Delta, Kappa, and Mu variants
In Vitro study testing combinations of plant extracts and micronutrients with several variants of SARS-CoV-2. A combination of vitamin C, N-acetylcysteine, curcumin, quercetin, resveratrol, theaflavin, naringenin, baicalin, and broccoli extract showed the highest inhibition of RBD binding, and also decreased RdRp, furin, and cathepsin L activity.

In Vitro studies are an important part of preclinical research, however results may be very different in vivo.
