According to Dr. Daniel More, a new study of persons with pollen allergies shows a decrease in sneezing (60%), runny nose (55%) as well as allergy symptoms generally from drinking Sapporo beer.
From Sapporo:
Sapporo Breweries Ltd, the company that makes Sapporo beer, has found that their beer is useful in treating allergic rhinitis symptoms because of the presence of hop flavonol glycosides, a natural anti-histamine. The company plans to also study the effects of beer on allergy symptoms related to dust exposure.
