The 19-year-old girl Tempestt Henderson addicted to eating soap and washing powder with a dangerous compulsion doctors say could kill her. A rare medical condition has left Tempestt Henderson, from Florida, eating up to five bars of soap a week. 'I remember the first time I dipped my fingers into the washing powder. I dabbed the powder onto my tongue and it tasted so sweet, and salty…it just felt so right. I was hooked straight away.' she said.
