This article cites a study on allergic contact dermatitis from Boswellia serrata extract in a naturopathic cream. The application of medicinal plant extracts to the skin may produce adverse effects including irritant contact dermatitis, phytophotodermatitis and allergic contact dermatitis. B. serrata is a tree from the Burseraceae family commonly found in India, northern Africa and the Middle East. Strips of its bark yield a gummy oleoresin which contains oils, terpenoids and gum. Its active principle consists of 4 pentacyclic triterpenes, b-boswellic acid being the major one.
