Extracted propolis has been used for a long time as a remedy. However, if the release rate of propolis isnot controlled, the efficacy is reduced. To overcome this issue, extracted propolis was added to a cryogen system. Propolis collected from southern Brazil was extracted using different methods and loaded at different concentrations into polyvinyl alcohol (PVA) and polyacrylic acid hydrogels as carrier systems. The material properties were investigated with a focus on the propolis release...
