Herbalgem Sanogem organic Spray Strong defense Concentrated gemmotherapy Organic farming Food supplement 15ml SANOGEM helps slow down the development of germs thanks to the combination of poplar and alder bud extracts, the main plant sources of Propolis. To produce propolis, bees collect almost exclusively the resins of poplar and alder buds, rich in flavonoids. Among other things, this propolis plays a hygienic role for bees, creating a protective layer against microbial or fungal invasions. While the poplar was considered a shield tree by the ancients, the black alder is robust and resistant to decay. Herbalgem Place des Chasseurs Ardennais 6690 Vielsalm Belgium
