World's hottest chilli grown, to be used as anaesthetic
Welsh farmer Mike Smith has grown what is being considered the world's hottest chilli pepper, with a Scoville scale rating of 2.4 million units of heat. Dragon's Breath chilli can be used as an alternative to anaesthetic because its oil can numb the skin, Smith said. It can cause anaphylactic shock, and Smith said it "burned" when he tried it.
