Colombo Wound Spray consists of a concentrated propolis extract. Propolis is a 100% natural product produced by bees. Propolis is a rich source of many herbs with a medicinal effect and vegetable products collected by bees from nature. This is why propolis has strong anti-bacterial and anti-fungal characteristics. Colombo Propolis Wound Spray has good adhesion to tissue but is not water soluble, this means it will stay on the wound for a long period of time providing protection for the wound against re-infection with bacteria and fungus.
