Clinical Trial Summary

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promotes challenging immune and inflammatory phenomena. Though various therapeutic possibilities have been tested against coronavirus disease 2019 (COVID-19), the most adequate treatment has not yet been established. Among candidate adjunct treatment options, propolis, produced by honey bees from bioactive plant exudates, has shown potential against viral targets and has demonstrated immunoregulatory properties.


Description:

To evaluate the efficacy and safety of oral propolis as an adjunct treatment for SARS-CoV-2 infection, we designed a randomized, double-blind, placebo-controlled trial (Bee-Covid2) (The Use of Brazilian Green Propolis Extract (EPP-AF®) in Patients Affected by COVID-19).
