Efficacy of Brazilian green propolis (EPP-AF®) as an adjunct treatment for hospitalized COVID-19 patients
This randomized, controlled, open-label, single-center trial was conducted on 124 patients with COVID-19 receiving either 0, 400 or 800 mg/day EPP-AF® brazilian green propolis for 28 days. All participants received standard care including all necessary interventions, as determined by physician.
Results indicate that the length of hospital stay post-intervention was shorter in both propolis groups (6 and 7 days for high and low dose respectively) than in the control group (12 days, lower dose, p = 0.049; higher dose, p = 0.009). Propolis did not significantly affect the need for oxygen supplementation. In the high dose propolis group, there was a lower rate of acute kidney injury than in the controls (p = 0.048). No patient had propolis treatment discontinued due to adverse events.
In conclusion, addition of propolis to the standard care procedures resulted in clinical benefits for the hospitalized COVID-19 patients, with a significant reduction in hospital stay.
