Quercetin Offers Allergy Relief
"In the video above, chiropractor Dr. Jin Sung highlights quercetin’s role in seasonal
allergies, noting that it demonstrates the greatest anti-allergy activity among avonoids
and works by modulating the release of histamine from basophils and mast cells.
In a study comparing quercetin with herbal water on histamine release from mast cells,
quercetin inhibited cells’ release of histamine by 95% to 97%. Other research shows
quercetin supplementation may reduce allergy symptoms such as sneezing, runny nose
and itchy eyes. The half-life of quercetin is 3.5 to 7.5 hours, so for best results you may
want to take it in divided doses.
Sung recommends a dose of 500 mg to 1,000 mg two to four times a day during allergy
season to help manage the symptoms, starting with the lowest dose — 500 mg, twice a
day — and gradually increasing if necessary.
Synergistic supplements for allergy relief, which you can take along with quercetin,
include stinging nettle, butterbur extract, mangosteen extract, ginger, vitamin C and
vitamin D."

Birch pollen and honey
"During birch pollen season in 2009, BPH patients reported a 60% lower
total symptom score (p < 0.01), twice as many asymptomatic days (p
< 0.01), and 70% fewer days with severe symptoms (p < 0.001), and
they used 50% less antihistamines (p < 0.001) compared to the control
group."
