Development of Phytophotodermatitis in Two Cases Related To Plantago Lanceolata

Abstract

Plantago lanceolata, also known as snake's tongue, is a perennial herbaceous plant from the family Plantaginaceae. It is a species widely distributed both in Turkey and all over the world. Today, its fresh leaves are still used to soothe and suppress cough, externally for wound healing and draining abscesses. Phytophotodermatitis (PPD) is a dermal photosensitive reaction induced by the contact to or oral intake of a plant and subsequent exposure to sunlight. Its acute course is called phototoxic. In this paper, two cases developed phototoxic reaction with the consumption of Plantago lanceolata and subsequent exposure to the sunlight. These cases were presented since such effect of the plant has not been known previously and there is no resembling case in the literature.
