Eel is warm and sweet, and has obvious effects of expelling wind and promoting blood circulation, strengthening yang and tonifying deficiency, and strengthening bones and muscles. It is suitable for patients with proctoptosis, internal hemorrhoid bleeding, mouth-eye deviation, earache and limb weakness. Deficiency heat is not suitable for eating.
Eat fresh eels. Eels that have been dead for more than half a day are not suitable for eating. It is better to kill and cook now. Because eel contains more histamine acid and trimethylamine oxide, after eel dies, histamine acid will be decomposed by decarboxylase and bacteria to produce toxic substances, and adults can be poisoned by taking 100 mg once. Trimethylamine oxide is also easy to be reduced to trimethylamine, which aggravates the muddy smell of eels.
