Abstract: 100 volunteers were employed in this study and divided into two groups randomly with 50 subjects in each group, i.e., treatment and control groups. People in the treatment group administrated TCP orally 2 times per day and 3 capsules per time. TCP was found to be effective in 28 cases, with a total effective rate of 56%. After a 30-day period, the color and area of chloasma decreased significantly as compared with those examined before TCP administration and control group, which indicted that TCP had the function of dispelling chloasma,and no obviously adverse influence on tested persons.
