Following preincubation for 1 h of PBMC with the extract, a significant inhibition of IL-1β, TNF, and IL-6 was observed at a concentration of 5 or 10 μg/mL (Figure 4A–C), with a similar potency when compared to 1 μM dexamethasone, the current reference treatment for COVID-19. This evidence concerns the gene IL1B and COVID-19.
