Lemon balm reduces some cardiovascular risk factors in type 2 diabetic subjects.

The purpose of this randomized and placebo-controlled study was to examine the effects of a lemon balm supplementation in subjects with type 2 diabetes. 62 patients have been recruited and have received for 12 weeks either a placebo or a lemon balm capsule (1400 mg/day).

Lemon balm

Results showed that lemon balm had significant effects on fasting blood glucose (p = 0.007), HbA1c (p = 0.002), triglycerides (p = 0.04), HDL-cholesterol (p = 0.05), hs-CRP (p = 0.001) and systolic blood pressure (p = 0.04). No change in total and LDL-cholesterol, insulin and insulin sensitivity have been noted.

These results suggest that lemon balm may improve the metabolic status of type 2 diabetic patients, reducing probably the risk of cardiovascular diseases.
