Erectile dysfunction, an early diabetic indicator, responds to treatment with pine bark extract, Slovakian researchers report. They tested 53 diabetic and non-diabetic patients with erectile dysfunction, giving half of them the extract (marketed as Pycnogenol) and the other half a placebo
for three months. The pine bark extract improved erectile function by 45 percent in the diabetes group and 22 percent in the non-diabetes group. It also lowered LDL cholesterol by 21 percent and reduced blood sugar levels in the diabetes group.
