The pine bark extract group had a significant reduction in hyperactivity and improved attention, visual-motor coordination, and concentration, whereas there were no positive effects noted in the placebo group. One month after pine bark extract treatment ceased, patients had recurrence of symptoms. Treatment was not significantly effective for girls in contrast to boys, but there were only 6 girls in the pine bark extract group.
An extract of pine bark has proven to be one of the most potent antioxidants, a property that may explain why pine bark has been used in folk medicine around the world, according to a new report by scientists at the University of California, Berkeley.
