SUMMARY A waitress, aged 38 years, developed acute contact dermatitis of her hands after chopping salad plants. Patch tests to radish ( Raphanus ) and to allyl wothiocyanate and benzyl wothiocyanate produced positive reactions. Sinigrin, the thioglucoside of allyl iso thiocyanate, was mixed in petrolatum with the enzyme myrosinase; the mixture produced a positive patch test reaction. Based on these preliminary findings, the immunochemical requisites of iso thiocyanates (mustard oils) are discussed. A tabulation has been made of exposure risk to plants of the mustard family (Cruciferae) which yield these compounds; the plants include some commonly used culinary vegetables, salad plants, condiments and also horticultural plants.
