Eating puffer fish can cure stomach diseases, which has been a folk prescription since ancient times. All experienced diners, as soon as the puffer fish is served, immediately roll the puffer fish skin into their mouths and can't wait to swallow it. People who eat puffer fish skin say that if you eat it several times a year, your stomach will not hurt. The health care function of puffer fish may be due to the extremely small amount of tetrodotoxin contained in skin and meat.
