Efficacy of Brazilian Green Propolis (EPP-AF®) as an adjunct treatment for hospitalized COVID-19 patients: a randomized, controlled clinical trial

Propolis, a natural product made by bees from bioactive plant parts and resins, is already extensively consumed in various regions of the world, due to its reputation as a health aid [9], [10], [11], [12], [13], [14], [15], [16], including immunomodulatory properties [17], [18] and antiviral activity [9], [18], [19], [20]. It is classified as a conventional food or food supplement in Brazil, a dietary supplement in the USA, a food supplement in the European Union, a functional food in Japan and Korea, and a health food in China [15], being a low cost and easily accessible product.

We hypothesized that propolis can reduce the negative effects of COVID-19.

We enrolled 124 patients; 40 were assigned to EPP-AF®️ 400 mg/day, 42 to EPP-AF®️ 800 mg/day, and 42 to the control group. The length of hospital stay post-intervention was shorter in both propolis groups than in the control group; lower dose, median 7 days versus 12 days (95% confidence interval [CI] -6.23 to -0.07; p=0.049) and higher dose, median 6 days versus 12 days (95% CI -7.00 to -1.09; 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 (4.8 vs 23.8%), (odds ratio [OR] 0.18; 95% CI 0.03 to 0.84; p=0.048). No patient had propolis treatment discontinued due to adverse events.

Addition of propolis to the standard care procedures resulted in clinical benefits for the hospitalized COVID-19 patients, especially evidenced by a reduction in the length of hospital stay. Consequently, we conclude that propolis can reduce the impact of COVID-19.
