So bees fly to some plants and they scrape these very, very sticky resins off the leaves, and they take them back to the nest where they cement them into the nest architecture where we call it propolis.
Então, as abelhas voam até certas plantas, raspam estas resinas muito pegajosas das folhas e levam-nas para a colmeia onde as incluem na arquitectura da colmeia, onde lhe chamamos própolis.
