Abstract:This project studied the health benefits of commonly found tree bark left behind in the wood industry. I measured the total polyphenol amounts, antioxidizing activity, microbial inhibition, and antimutagenic effects of four types tree bark. The results showed that tree bark–often considered a waste product–is abundant in polyphenols and antioxidants, and also shows antimicrobial and antimutagenic effects.
