Pycnogenol Decreases Allergy Symptoms
HOBOKEN, N.J.—A study published in the June 14, 2010 issue of Phytotherapy Research demonstrated Pycnogenol®, an antioxidant plant extract derived from the bark of the French maritime pine tree, substantially improves the symptoms of hay fever.
In a randomized, double blind, placebo-controlled study conducted by KGK Synergize Inc.,60 subjects between the ages of 18 and 65 began treatment three to eight weeks prior to the onset of birch allergy season in Ontario, Canada. All subjects tested positive for birch pollen allergies, a seasonal trigger of hay fever, as determined by skin prick tests. Patients were assigned to a Pycnogenol group or placebo group according to a computer-generated, randomized schedule. Subjects were instructed to take either 50 mg of Pycnogenol or placebo twice daily, once in the morning and once in the evening throughout the allergy season. Patients were allowed to use non-prescription antihistamines as needed and recorded usage and dosage in treatment journals.
