Standardization of propolis: present status and perspectives

Vassya Bankova and Maria Cristina Marcucci

Propolis has been known for its healing properties for centuries, and today many propolis products are available commercially. However, propolis collected from different regions of the world will have different compositions and will vary in activity. It is therefore important to establish standards for the composition of propolis,
where the presence and amount of important constituents, and absence of contamination can be determined.
