| Abstract: | A 57 years old trader of agricultural goods with chronic asthma had attended our medical department for diagnosis and therapy. Since more than 35 years the patient had always experienced work-related asthma episode and rhinoconjunctivities when he worked in workplace where castor-bean oil cake as fertilizer was sold. With the intensive contact with castor-bean containing goods beginning about eight years ago, his asthma attack had become chronic.
