Zinc is a metalic mineral (not an herb) present in trace amounts in the human body, animals, and plants. Zinc, as well as other minerals, are needed in very small amounts in order for the body to function properly. Zinc is considered a coenzyme that helps some enzymes work properly.
Zinc is required for proper wound healing. It was used topically as far back as 1,5OO B.C. by the Egyptians, and to this day bandages often contain zinc oxide to help speed healing. It is also well-documented that people with zinc deficiencies experience delayed wound closure and an increased susceptibility to infection.
