Pijnboomextract tegen tinnitus*
Uit een Italiaanse studie blijkt dat pijnboomschorsextract goed kan werken in
het tegengaan van tinnitus, ook wel
oorsuizen of fantoomgeluid genoemd. Patiënten kregen dagelijks of 100 mg of 150
mg van dit extract dat rijk is aan proanthocyanen.
Alle deelnemers hadden al binnen 4 weken een duidelijke verbetering en zij in de
150 mg groep zelfs nog meer. Proanthocyanen zorgen voor een betere
bloeddoorstroming tot zelfs in de kleine bloedvaatjes in het oor.
Treat tinnitus with pine bark
A new study out of Chieti-Pescara University in Italy has found that extract
from the bark of French maritime pine trees is effective at treating tinnitus, a
hearing condition that can cause severe ringing, hissing, and rushing noises.
Research indicates that pine bark extract, which is rich in antioxidants, helps
to improve blood flow to the ear and thus eliminate tinnitus symptoms.
"Impaired blood flow to the ear is a common cause for tinnitus, a
disturbing and very debilitating condition that can considerably impact overall
health and quality of life," explained Dr. Gianni Belcaro, lead researcher
of the study. "With few options available for treatment, this study gave us
the opportunity to explore a natural solution to tinnitus symptoms and its
causes."
When compared to a group not receiving the treatment, patients given Pycnogenol,
a branded form of the pine bark, experienced a significant improvement in blood
flow to their inner ears after just four weeks of treatment. And among those
taking Pycnogenol, those in the high dose group (150 mg/day) experienced even
greater improvements that those taking lower doses (100 mg/day).
Researchers also observed an overall improvement in felt symptoms among those
taking Pycnogenol. Pain symptoms were reduced by 41 percent in the low dose
Pycnogenol group while the high dose group experienced a 63 percent reduction in
pain symptoms.
"The study clearly indicates Pycnogenol's ability to improve vascular
function and restore cochlear blood perfusion, which in turn relieves the
severity of tinnitus symptoms," stressed Dr. Belcaro. "The results
provide further evidence of the supplement's natural efficacy for a variety of
vascular health problems." (Januari 2011)
