Bismuth which is also known as pepto bismol helps increase ulcer healing by binding to the ulcer base , providing a sense of protection. Applying some to a cold sore after the skin has broken can speed up the healing process because the bicarbonate reestablishes the pH levels. It's a cheap substitution for abreva.hope this helps!
