Peptide immunotherapy is an attractive approach to relieve allergic symptoms such as rhinitis and asthma. Treatment of Japanese cedar pollinosis (Cryptomeria japonica; Cj), from which over one quarter of Japanese population suffer, is becoming a great concern. Recently, oral feeding of a peptide

Allergic reaction to Cupressaceae and Taxodiaceae pollens appears to be on the increase in the last years in Italy. An epidemiological survey on this pollenosis was conducted in 12 Italian centers. The diagnostic panel consisted of seven Cupressaceae and Taxodiaceae genus (Cupressus sempervirens,
