Is the cytokine suppression provided by boswellia serrata helpful in cases of covid-19 infection?

Uncertain: Per The Andrew Weil Center for Integrative Medicine- " Pre-clinical studies have shown that Boswellia extracts inhibit a broad range of inflammatory cytokines which suggests that this herb is unlikely to be harmful, and may in fact, be helpful in someone with mild symptoms of Covid-19 infection."
