THEY EVEN HEAL WOUNDS
I recently read a report on eggs being used to speed up wound healing. Wounds dressed with egg membrane heal at least 20% faster and less scarring occurred. It makes sense to me that the egg membrane could be used in this way as it has the function in the egg of protecting against bacteria entering into the white and yolk. It is similar in structure to the extracellular matrix of human skin. Apparently in the early 1900s the egg membranes were used for their healing properties so this was known about a long time ago. Seven or eight membranes covered the wound, topped with silver foil and antiseptic bandages; after four days the membranes had grown into the tissue causing new skin to grow!
A company is now taking the membranes from the discarded egg shells used in the food trade, crushing them into powder and then using them in dressings to treat wounds such as leg ulcers that take a long time to heal. A trial is already under way.
