The aim of present study was to investigate the effect of chilli pepper (Capsicum annuum L.) extract on adipose tissue, total cholesterol and some of histological characterizes of tissues. The current study used 60 white mice, split into three treatment groups with control group, including 15 mice in each group. The treated groups received three doses that varied in concentration of watery hot chilli pepper extract; Group A was the normal control group. Group B, C and D received orally 0.5 ml of chilli pepper for 30 days with concentrations of 0.4, 0.8 and 1.6%, respectively. The adipose tissue showed significant differences in the biometric dimensions of adipose tissue nuclei after being treated with moderate (0.8%) and high (1.6%) doses of water hot chilli pepper extract. In conclusion, the high concentration of watery chilli pepper extract displayed tissue structure with many histological alterations, in contrast to the prior groups that received the moderate and lower doses.
