title: A study of western red cedar-induced asthma.
abstract: Seventeen asthmatic patients who were workers dealing with Western Red Cedar in a Japanese wooden frame factory were studied. One fraction from the aqueous extract of the lumber induced a positive skin test, Prausnitz-Kustner test and the inhalation test. This confirms the existence of antigen in Western Red Cedar and its ability to produce allergic asthma in sensitive workers.
