Methods : In order to study the effect of oral administration of phenolic compound extracted from pear and herbal drugs(Platycodon grandiflorum, Prunus armeniaca) on allergic asthma, mice were pre-treated by oral administration of the solution before antigen sensitization four times for 8 days. 2 days later, mice were actively sensitized with a subcutaneous injection of ovalbumin and 13 days later, they were provoked with ovalbumin aerosols. The animals were divided into four groups; Saline, orally administered saline. PC-A, orally administered Phenolic compound extracted from pear peel 10mg/kg/ml. PC-B, orally administered Phenolic compound extracted from pear peel and flesh 10mg/kg/ml. PC-C, orally administered pear 10m/kg/ml, Platycodon grandiflorum 24.4 mg/kg/ml and Prunus armeniaca 33.3 mg/kg/ml. Serum level of IgE, IL-4, cell numbers in the bronchoalveolar lavage fluid(BALF), and in vitro isometric contractile responses of the isolated tracheal smooth muscle(TSM) to acetylcholine(ACh,
