Clinical Trial Summary

This work aims to evaluate the effects of the association of green propolis extract with royal jelly on inflammation and oxidative stress in participants with chronic kidney diseases (CKD) and Systemic arterial hypertension (SAH), in a longitudinal, randomized, double-blind, placebo-controlled clinical trial that will be carried out for 2 months.

Description:

Propolis and royal jelly are bee products. Propolis is a resinous mixture produced by bees with their saliva and the addition of wax, from exudates collected from buds and plant sap. Royal jelly is a substance produced in the hypopharyngeal glands of young worker bees. Both products are rich in bioactive compounds such as polyphenols. The combination of propolis extract and royal jelly, substances constituted by the combination of several chemical components with potential biological activity, may emerge as a promising adjuvant therapeutic alternative for patients with CKD and SAH.
