Abstract:
Background: As a complementary medicine we have evaluated the efficacy of Benihuuki green tea, which contains methylated form of tea catechin reported stronger anti-allergic activities than ordinary catechin, on Japanese Cedar Pollinosis (JCP) in comparison with Yabukita green tea, contains ordinary catechin. This study was carried out during the pollination season, Feb.–April, in 2005.
Method: Four hundred eighty six patients with JCP, visiting 12 otorhinolaryngology clinics in Fukuoka prefecture were divided into A and B groups and subjected to quasi-single blind clinical trials. Under ordinary conditions, A-group patients took Benihuuki green tea and B-group took Yabukita green tea every day from February 1st to the end of Japanese cedar and Cupressaceae pollination season. We compared nose and eye symptom scores, medication scores and disturbance of quality of life (QOL).
Result: There were no differences observed between the two groups with respect to their symptom scores and the disturbance of QOL. However, decreasing trend of the medication scores was observed in A-group (p < 0.1).
Conclusion: It has been suggested that Benihuuki green tea is a possible candidate as a complementary medicine for JCP during the pollination season.
