Recently, British Welsh chef Mike Smith, with the help of scientists from Nottingham University, cultivated the world's hottest pepper. He named this pepper "Dragon Breathing". According to scovill's spicy degree testing system, the spicy degree of "Dragon Breathing" exceeds 2.48 million units. Scovill's hot degree detection method is to dilute pepper juice until it can't taste hot. 2.48 million units means that the pepper juice is diluted by 2.48 million times to completely neutralize the spicy taste. Experts believe that if one of these peppers is swallowed, anyone may die of anaphylactic shock. Its spicy flavor volatilizes into the air, and even causes anaphylactic shock. Therefore, it must be kept tightly in a special container. Smith said that "Dragon Breathing" has received a certificate from the Guinness World Records Certification Body, confirming that it is the hottest pepper in the world. Smith hopes that "dragon exhaling" can be used in medical treatment rather than used as ingredients.
