Analysis of propolis Monitoring recommendations
High quality propolis should be tested for common quality parameters, in particular the content of polyphenols.
Furthermore, as a natural bee product with a highly variable composition, propolis also has to be free of any antibiotic residues derived from beekeeping practices and from contaminants caused by pollution. Raw propolis is known to accumulate considerable amounts of pesticides as well as heavy metals, especially Lead.
