| Detailed Product Description: |
| from chinese,is best beeproduct!Raw propolis is collected by beekeepers and sold in bulk to companies that refine the product and turn it into usable extracts. Most commercial uses of propolis are based on preparations made up from these extracts. Methods include ethanol extraction (EEP), glycol extraction (GEP), aqueous (water) extraction (AEP), oil extraction (OEP), and water-soluble derivatives (WSD). Where solvents are used, reduction or elimination of the solvent is necessary, either by freeze-drying, vacuum distillation, or evaporation. Extraction is used to remove the beeswax which is mixed with the propolis by the bees during use in the hive, as well as other non-active components such asresinous-balsam substances |
