GEM-SANA helps to slow the development of germs thanks to the combination of poplar and alder, the main plant sources of propolis.
The bees collect the resins of these two buds rich in flavonoids for the production of their propolis.
This propolis has, among other things for bees, a hygienic role by creating a protective layer against microbial or fungal invasions. The poplar bud has long been considered "propolis like" a shield tree, and glutinous alder is a hardy and rot resistant species.
