CHEILITIS CAUSED BY CINNAMON (CASSIA) OIL IN TOOTH PASTE

Abstract
Cheilitis and stomatitis are disorders commonly seen in clinical practice. Zakon, Goldberg, and Kahn1 reported 32 cases of cheilitis due to lipstick (the commonest offenders in this group being the bromfluorescein dyes) and, in reviewing the literature, found many additional causative agents, including actinic or chemically active rays of sunlight, allergy to cold, carmine, aniline, and eosin dyes in lip rouge, trout, methyl heptane carbonate in the perfume of lipstick, dental plates (Hecolite), denture creams containing anise oil, mouth washes, cigarette holders, bromfluorescein dyes, mustache wax, amalgam fillings for teeth, oil of cloves, orange juice, tomato juice, hexylresorcinol, Italian reed, metal containers for lipstick, mango rinds, tincture of Krameria, sage tea, and strong artificial lights such as carbon arcs. Only one case of cheilitis caused by cinnamon (cassia) oil has been reported previously. Miller2 reported the case of a woman who contracted cheilitis after approximately five weeks' exposure
