3.2.4 Anti-oxidative stress indicators
The efficacy of Icariin and its derivatives in anti-oxidative stress indicators is also excellent (Table 4) , which can not only significantly up-regulate the SOD level (p = 0.000) under low heterogeneity (I2 = 0.0%, p = 0.047), but also can inhibit the MDA activity (p = 0.000), so as to achieve the effect of anti-oxidative stress, and then inhibit the process of inflammation, details are shown in table.
