Rosemary contact dermatitis and cross-reactivity with other labiate plants.
Rosemary, a plant belonging to the labiate family, is frequently used in the making of cosmetics and also for medicinal purposes. There are few reported cases of contact dermatitis due to this plant. Here we present 1 case and asses the existence of cross-reactivity with plants from the same family. 53-year-old man with several episodes of a pruritic and erythematous eruption that resulted in peeling of the skin, after applying rosemary alcohol, on the chest reported. Epicutaneous tests were done with the standard European series (GEIDC), with the commercial plant series (Bial-Aristegui) and with plants from the labiate family. Results were positive for 3 of 4 labiate species tested. we present a case of rosemary contact dermatitis, where we have found cross-reactivity with 3 of 4 species tested from the same family.
