propolis胶囊

,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. appearance: (room temperature,) was powdered, brown red or brown-yellow Propolis content: 40% -80% Total flavonoids content: (%) 6.0 Heavy metal content: Pb <1ppm Package Size: 1kg / bag, 20kg / box (barrel) 5kg / bag, 20kg / box (barrel)
