Propolis by ESC Laboratoire is produced by bees as a natural shield to protect and cleanse the hive. Its properties have been recognized for millennia. It is in fact a concentrate of active ingredients: flavonoids, phenols, coumarins, essential oils... which give it virtues both for internal and external use. Applied externally, this care product supports the healing process and used as a food supplement, it helps to strengthen the body and boost the immune system.
