Pine bark extract can alleviate the symptoms of pollinosis

According to the research, it can alleviate the symptoms of pollinosis by adding pine bark extract every day Taking Pycnogenol supplements for seven weeks can also reduce the use of over-the-counter antihistamines, requiring only 12 5% versus 50% for the control group Pollinosis is the most common disease of pollen allergy or mycospore According to the American asthma and Immunology report, there are about 600000 people suffering from allergic rhinitis in the United States When harmful invaders and leukocytes - T-helper type 2 (Th2 cells) - produce proteins such as cytokines such as IL-4, IL-5 and IL-6, the immune system will confuse spores, thus promoting the synthesis of immune immune immune chemicals immunoglobulin, binding with pollen and competing with the immune system The researchers studied the pollen specific immunoglobulin E (IGE) levels in 60 patients with birch pollinosis Throughout the allergy period, participants were given either a continuous pine bark extract supplement (Pycnogenol 100mg daily) or a control The results showed that the IgE level of the control group increased by 32% But the pine bark extract group increased only 19% Pycnogenol can relieve nose and eye symptoms in patients with allergic rhinitis, the researchers said This means Pycnogenol can represent a new and promising treatment for allergic rhinitis Study details Wilson and his colleagues recruited pollen fever patients aged 18-65 in Ontario, Canada These patients took pine bark extract (Pycnogenol) or control for 8 weeks before allergy The results of this randomized, double-blind, control trial showed that after taking Pycnogenol, when they were exposed to pollen, the symptoms of hay fever were prolonged for 5 weeks Our results show that Pycnogenol, taken at the right time and in the right dose, has a good effect on the symptoms of pollinosis, the researchers pointed out Unfortunately, there were only eight patients who took Pycnogenol for seven to eight weeks and then came into contact with birch pollen, which was too small to provide statistical data As a further response variable, the larger the dose of Pycnogenol, for example, the use of previous asthma studies may help to highlight the role of relieving rhinitis symptoms Based on the positive results of this study, it is likely to get a higher sample, which will provide greater significance between Pycnogenol and the control group.
