Propolis is a mixture of some secretions from bees and resins from plants. To protect the hive and its nutritious contents from attack by micro-organisms, propolis has anti-microbial properties. Propolis is composed of chemicals (especially flavonoids), which play a role as antiviral and antibacterial agents.
Laboratory tests have demonstrated that propolis is effective against over 20 kinds of bacteria. Clinical studies also demonstrated that propolis was effective against various kinds of bacterial, fungal, and viral infections. According to recent study, active ingredients in propolis significantly inhibited flu virus also.

| As it is getting more strict in using antibiotics globally, people are highly concerned about organic food and meat. Samjo Life Science goal is to produce a variety of feed additives contain propolis (phytonutrient) and to supply those for our customers.
According to recently report Phytotherapy Research in 2010, a substance in propolis was active against MRSA, which causes potentially fatal infection. They tested extracts of propolis on 15 MRSA strains and isolated two compounds, Propolin C and Propolin D, which showed good activity against all the MRSA strains tested. These could possibly act as templates for the development of improved anti-MRSA agents.
