Popular painted-on "black henna" tattoos may cause allergic reactions capable of leaving permanent scars, Florida health officials warn.
The advisory comes after the families of three teenage tourists reported bad reactions to the tattoos, some of which may be made by a chemically treated "black henna" that is being billed as all-natural, the Associated Press reports.
The tattoos, painted on the skin with a pen-like tip, typically last three to four weeks. Frequently offered by tourist-luring T-shirt shops and souvenir stores, they often depict flowers, daggers and Asian art. – (HealthDayNews)
