This is a thirty two years old male patient who work as a software engineer. After he drank lots of alcoholic drinks with his colleague in Nov, 2012, he found that there were mucous lesions in his left side of mouth on the next morning. Those mucosal lesions were very painful and didn’t heal on their own, so he decided to ask for medical treatment. The doctor diagnosed his mucosal lesions as Recurrent Aphthous Stomatitis and gave him no treatment. In the Chinese New Year of 2013 he drank lots of alcohol drinks, his mucosal lesions became very bad this time and went to our hospital for help on 10, Apr, 2013. We found out that he was an imbalanced condition of his yin-yang. We decided to use the traditional Chinese herbal medicine to balance the yin-yang and heal the mucosal lesions. After the treatment, his mucosal lesions were healed and no longer painful, and the accompanying problems all got better, such as bad breath, swelling gum, dry mouth…etc. This is a successful case of treating recurrent aphthous stomatitis by Chinese medicine.
