Kombucha SCOBY can be used as a living Band-Aid! You can use pieces of the culture topically to speed healing of cuts, burns and other wounds. Cut a piece to size and hold in place with a bandage wrap. It will sting a bit, much like iodine. The pH of the culture inhibits the growth of harmful organisms. • The bacteria send out microfibrils which are filament strands that link up with those of other bacteria creating a nano-structure that thickens over time.
