A ghost pepper, also known as Bhut Jolokia, is a type of chili pepper known for its extreme spiciness. It is one of the hottest peppers in the world, with a rating of over one million Scoville heat units on the Scoville scale. Ghost peppers are native to the northeast region of India, and are often used in Indian cuisine to add heat to dishes. They are also used in traditional medicine to treat stomach problems. Because of their intense heat, ghost peppers should be handled with care and avoided by those who are sensitive to spicy foods.
