AbstractThe iatex exuding from the freshly sliced stems/leaves of 11 Indian plants was tested on 10 volunteers each by the open patch test and in 5 volunteers each by the 48 hour occluded patch test technique. In the open patch test, there was no reaction with (1) calotropis procera, (2) Alstonia scholaris,(3) Euphorbia splendens, (4) Euphorbia clarkina (5) Nerium indicum, and (6) Padilanthus tithymaloides (Green and white leaf variety), while mild reactions were observed with Euphorbia pulcherrima in 3 volunteers, Ficus elastida in 2 volunteers, and Pedilanthus tithymaloidas (Green leaf variety ) and Plumeria indica in one volunteer each Sapium sebiferum on the other hand produced severe itching, burning and erythema in all the 10 volunteers. The 48 hour occluded patch test produced definite reactions with Pedilanthus tithymaloides (Green leaf variety)in 2 cases and calotropis procera and Euphorbia clarkina in 1 case each. Sapium sebiferum on the other hand produced cauterization type of reactions in all the cases.
