Efficacy of mulberry leaf tablets in patients with mild dyslipidemia.

Mulberry leaf is well known for its several biological effects. The purpose of this study was to evaluate the hypolipidemic effect of mulberry leaf in non-diabetic patients with mild dyslipidemia. A within-subjects research design was conducted at the out-patient clinic in Thailand. Twenty-three patients who met the NCEP ATP III criteria guideline for dyslipidemia and failed a 4 week diet therapy were enrolled and assigned to receive three tablets of 280 mg mulberry leaf tablet three times a day before meals for a period of 12 weeks. Routine blood analyses including lipid parameters and liver function tests were performed every 4 weeks. At 4 and 8 weeks of mulberry leaf tablet therapy, triglyceride was significantly decreased by 10.2% (p < 0.05) and 12.5% (p < 0.05), respectively, from baseline. At the end of the study, total cholesterol, triglyceride and LDL were significantly decreased by 4.9% (p < 0.05), 14.1% (p < 0.05) and 5.6% (p < 0.05), respectively, from baseline, whereas HDL was significantly increased by 19.7% (p < 0.05). Even though some patients experienced side effects such as mild diarrhea (26%), dizziness (8.7%) or constipation and bloating (4.3%), mulberry leaf tablet therapy is still capable and safe in reducing cholesterol levels and enhancing HDL in patients with mild dyslipidemia.
