Anti-allergy composition comprising wood vinegar- or bamboo vinegar-distilled solution

摘要

The anti-allergy composition of the present invention comprises, as an ineffective ingredient, a wood vinegar-distilled solution. A bamboo vinegar-distilled solution obtained using a bamboo as a wood material is preferable. Also, it is preferable that the present composition does not contain benzopyrene, dibenzanthracene, and methylcholanthrene substantially. The anti-allergy composition can exhibit an anti-allergy effect by oral ingestion. In particular, it is useful for inhibiting Type I allergy such as allergic rhinitis, hay fever, allergic conjunctivitis, atopic dermatitis, allergic asthma, urticaria, food allergy, and anaphylaxis. In addition, the composition can be also applied to a skin. When a wood is subjected to smoking treatment at 130 to 170° C., dried, and then carbonized at 350 to 450° C., a smoke discharged during this carbonization treatment is condensed to obtain a crude wood vinegar, and then the crude wood vinegar is distilled at a low temperature of 50 to 60° C. under reduced pressure to obtain a wood vinegar-distilled solution.
