A Case of Primary Irritant Dermatitis due to Ranunculus Tachiorei / 대한피부과학회지

Ranunculus tachiorei is a member of the buttercup family (Ranunculaceae) which contains unsaturated lactone and protoanemonine. Protoanemonine is formed by the breakdown of the glycoside Ranunculin after injury to the plant and causes severe vesiculation and linear streaks after contact with field buttercups(Ranunculus spp.) The amount of protoanemonine in buttercups varies widely with the species of plant and its stage of growth, the highest content being at the time of flowering. We report a case of primary irritant dermatitis due to contact with Ranunculus Tachiorei which was applied for the folk treatment of Bell palsy.
