11/15/2018:  I learned today the my patent application for creating a bio active bandage or dressing with protocatechuic acid (PCA) will be published on December 4, 2018.  This bandage has the antibiotic and wound acceleration reagent (PCA) within.  When on a wound that causes the bandage to be moistened, the PCA is activated and kills a broad spectrum of microbes and accelerates the wound healing.  This is particularly important for diabetic and varicose ulcer wounds.
