crude-propolisPropolis is a substance made by the honeybee that provides
protection against harmful
bacteria, viruses and fungi. propolis is plant resin collected by bees foruse in
and around the hive. In plants it is usually the sticky coating around buds
that serves to protect them from the elements of weather plus from attack
bybacteria, fungi, molds, and viruses. These are properties that are useful to
the
bees and are enhanced by the sticky properties of the propolis. Like pollen,
propolis
is a bee product that cannot be clearly defined and varies from sample tosample.
This is a natural outcome of the collection process. Propolis collecting
bees will use resins from a large variety of tree and other plant species,
andthese naturally will differ in their qualitative and quantitative chemical
composition.
Nevertheless, different propolis samples do share considerable similarityin
their physical and overall general chemical nature. Hundreds of chemical
compounds have been identified from propolis. The main chemical
classes present in propolis are flavonoids, phenolics, and various
aromaticcompounds. Propolis also contains some volatile oils, terpenes, and beeswax,but these compounds are not believed to contribute as significantly to the chemical properties and effects of propolis. Flavonoids are well-known plant compounds that have antioxidant, anti-bacterial,
anti-fungal, anti-viral, and anti-inflammatory properties. Other propertiesof
propolis include acting as a local anesthetic, reducing spasms, healing gastric
ulcers, and strengthening capillaries.
