Scientific research has shown that propolis strengthens our natural immune system and has an anti-inflammatory, antibacterial, antifungal and antiviral effect.

We examine the source substances for value-determining ingredients (e.g. flavonoids) as well as for possible harmful substances (heavy metals, pesticides, aflatoxins, etc.) before they are gently processed.
