Abstract

The ethanol extract of Syzygium aromaticum (clove) has attracted attention for its potential effects on lipid metabolism and body weight. The current study investigated the effects of the ethanol extract of Syzygium aromaticum (clove) leaves on the lipid profile and body weight changes in testosterone-induced benign prostatic hyperplasia (BPH) rats. Thirty-six rats were divided into six groups (n = 6/group): normal control, clove extract only (600 mg/kg body weight), testosterone-induced BPH control, finasteride-treated testosterone-induced BPH (3 mg/kg body weight), clove extract-treated testosterone-induced BPH (300 mg/kg body weight), and clove extract-treated testosterone-induced BPH (600 mg/kg body weight). The animals’ body weight was recorded weekly. Treatment lasted for 28 days, after which blood samples were collected for biochemical analysis. Lipid profile analysis showed significant decreases in triacylglycerol, total cholesterol, low-density lipoprotein, and very low-density lipoprotein concentrations in the treatment groups compared with the testosterone-induced BPH control. A significant increase in high-density lipoprotein cholesterol concentration was observed in the treatment groups compared with the testosterone-induced BPH control. Additionally, body weight increased significantly in the treatment groups compared with the testosterone-induced BPH control. These findings suggest that the ethanol extract of clove leaves has anti-hyperlipidemic effects in BPH and may modulate body weight by promoting metabolic activity.
