Pepper has been used to relieve pain since ancient times, but scientists have only recently learned that capsaicin can stimulate and exhaust the neurotransmitter "P", which can spread pain information to the whole nervous system. Through the analgesic principle of capsaicin, pepper paste has been used to relieve pain such as herpes zoster and trigeminal neuralgia.

Pepper will turn the skin red.

When capsaicin is applied to the skin, it will dilate microvessels, promote circulation and make the skin red and hot. At present, some manufacturers have used this principle to put capsaicin into socks and become "Chili socks" for heating in winter.

Pepper can relieve the discomfort caused by a cold.

For thousands of years, spicy food has often been thought to eliminate phlegm, and now it seems to be the same. Spicy food can dilute secreted mucus, help expectorate, and not block the respiratory tract. Professor Evan Ziman of the University of California even said, "Many cold medicines and cough medicines sold in pharmacies have exactly the same effect as Chili, but I think eating Chili is better because it has no side effects at all. 」

Pepper can prevent cancer.

According to epidemiological studies, many spicy ethnic groups, such as Southeast Asia and India, are less likely to get cancer than western countries. Scientists speculate that these spicy foods contain many antioxidants, and oxidation is directly related to chronic diseases, cancer and aging. Recently, a study by the University of Hawaii in the United States pointed out that carotenoids in vegetables such as peppers and carrots can stimulate genes that transmit information between cells, because when organs become cancerous, the system for exchanging information between cells will fail, which may play an important role in preventing cancer.

Pepper can prevent arteriosclerosis.

Red pepper contains the daily required amount of beta carotene, which is a powerful antioxidant and can treat the oxidation of low-density cholesterol into harmful forms. Once the low-density cholesterol is oxidized, it will turn into a bad substance and block the arteries like cream in the refrigerator. In other words, beta carotene began to intervene in the early stage of arteriosclerosis.

The disadvantages of eating Chili

Although pepper is rich in nutrition and has important medicinal value, excessive consumption is harmful to human health. Because too much capsaicin will violently stimulate the gastrointestinal mucosa, make it highly congested, accelerate peristalsis, cause stomach pain, abdominal pain, diarrhea and anal burning and stabbing pain, induce gastrointestinal diseases, and promote hemorrhoid bleeding. Therefore, anyone suffering from esophagitis, gastroenteritis, gastric ulcer and hemorrhoids should eat less or avoid eating Chili. Because pepper is pungent and hot, you should also be careful to eat hot diseases, such as burning eyes, toothache, sore throat, hemoptysis, furuncle, or hypertension and tuberculosis with yin deficiency and fire flourishing.
