In the positive control group did show a significant reduction in total cholesterol compared with the treatment group I (p = 0.347), II (p = 0.251), and III (p = 0.347). While the levels of LDL decline in the positive control group and the treatment also did not differ significantly, with the value of the treatment group I (p = 0.347), II (p = 0.465), and III (p = 0.347).
