Temporary henna tattoing has been very popular during recent years. Henna is a greenish powder made from the leaves of Lawsonia alba containing lawsone (2 hydroxyl-1, 4-naphtho-quinone) as the active substance. It is used alone or in combination with other coloring agents, such as paraphenylenediamine (PPD). PPD is a potent contact allergen associated with a high incidence of hypersensitivity reactions.
