New research shows Pycnogenol French maritime pine bark extract, from Natural Health Science, is effective in relieving tinnitus symptoms and improving inner ear blood flow. The study was recently published in Panminerva Medica. Tinnitus is a hearing condition that causes the constant misperception of sound, including hissing, ringing and rushing noises.
For this study, conducted by the Chieti-Pescara University in Italy, 82 patients between the ages of 35 and 55 with mild-to-moderate tinnitus in only one ear, while the other remains unaffected, were studied throughout a 4-week period. Tinnitus in all subjects was a result of restricted blood supply to the inner ear, as measured by high resolution ultrasonography imaging of their cochlear blood flow. Patients were assigned to one of three groups: A, B and control. Group A consisted of 24 patients who were administered 150 mg/day of Pycnogenol, group B consisted of 34 patients who were administered 100 mg/day of Pycnogenol, and the control group consisted of 24 patients who received no Pycnogenol. None of the patients had previously used medication for their tinnitus symptoms.
At the beginning of the study, patients’ average initial systolic and diastolic blood flow velocities were 14.3 and 4.22 cm/sec in the low dose Pycnogenol group and 13.2 and 3.2 cm/sec in the high dose Pycnogenol group, indicative of insufficient blood perfusion of the ear in both groups. The study found that after four weeks of treatment with Pycnogenol, inner ear systolic and diastolic blood flow velocities in the affected ear rose to an average of 21.2 and 8.23 cm/sec in the low dose group and to 24.3 and 12.5 cm/sec in the high dose group.
The study also indicates Pycnogenol improves vascular function and restores cochlear blood perfusion, which in turn relieves the severity of tinnitus symptoms. For further information: www.pycnogenol.com
