After cutting chili peppers, the hand is as painful as being burned by fire, hot and spicy. At this time, some people will use cold water to rinse, but this can only slightly relieve the pain, can not completely solve the problem. In fact, you can use the application of alcohol, vinegar, hot water to wash your hands and other methods to remove the spicy flavor. \x0d\\\x0d\\ The substance that produces the spicy flavor in chili peppers is capsaicin, collectively known as capsaicin. When cutting chili peppers, capsaicin gets on the skin and causes microvascular dilation, leading to redness and heat and accelerating the local metabolic rate. At the same time, it also stimulates the pain nerve, which is why we usually feel burning hands. It is generally believed that this is caused by the chemical transformation of nerve endings in the skin by capsaicin. \x0d\\\x0d\\capsaicin is soluble in ethanol and alkaline aqueous solutions, but not in cold water. In industry, the extraction of capsaicinoids from chili peppers is done by using edible alcohol as an extraction agent. Therefore, according to this principle, in life, you can take the method of applying alcohol to dissolve the capsaicin on your hands. After cutting chili peppers, you can use an alcohol cotton ball to rub your hands in one direction, then wash your hands with water, and then wipe them dry, and rub them three times in a row until the symptoms are relieved. \x0d\\\\x0d\\Additionally, a small amount of vinegar can be used to wash your hands, this is because vinegar is acidic and can be neutralized with capsaicin. If there is no medical alcohol nor vinegar, washing hands with hot water is also good because capsaicinoids will produce irritating evaporation at high temperatures, which is not as good as alcohol and vinegar, but more effective than cold water. \x0d\\\x0d\\ actually when cutting chili peppers, you can use your finger bellies to press on the chili peppers instead of pinching the peppers with your fingernails, so that your hands won't get burned easily
