A small kind of pepper grown in the northeast mountainous area of India and locally called "ghost chili" has been listed in the Guinness Book of Records as the spiciest pepper in the world. This blood-red "ghost chili" grows in the northeast mountainous area of India. Local farmers said that once you take a bite, the spicy smell will immediately rush into your mouth. Besides making your tears and nose water flow nonstop, it also creates a death-like hallucination, hence its nickname "ghost chili". Farmers even advise outsiders not to eat the "ghost chili" casually; if swallowed whole, all the body's senses will be overwhelmed by its spiciness. The spiciness of peppers is measured according to the amount of capsaicin they contain; when bitten, capsaicin releases the spicy smell. Scientists use the Scoville sensory assessment method to measure spiciness; the higher the Scoville value, the spicier the pepper. Scientific tests have confirmed that the "ghost chili" contains over one million Scoville units, while the everyday chili sauce used in Western meals only contains 2,500-8,000 Scoville units. The former record holder for the spiciest pepper, the Red Savina Habanero, only had 580,000 Scoville units, showing just how incredibly spicy the "ghost chili" really is.
