Figure 3: Changes in epidermal thickness of extract of Woodfordia fruticosa treated mice. Each bar represents mean ± standard error of mean for 6 mice per group. Data were analyzed by one-way analysis of variance, followed by Tukey-Kramer multiple comparisons test, values were significantly different from those of control group: *P < 0.05, **P < 0.01, and ***P < 0.001, a-significant difference as compared to Group I, b-significant difference as compared to Group II, c-significant difference as compared to Group III
