In ancient times, there was a saying that "drinking baijiu and eating raw leeks can lead to illness." In the "Yin Zheng Yao Yao," there are also records such as "leeks should not be eaten with alcohol," and the reasoning is generally related to the medicinal properties of food.
Baijiu is sweet, pungent, slightly bitter, and has a very hot nature. It contains about 60% ethanol. One gram of ethanol burns in the body to produce 7100 calories of heat. Ethanol is metabolized in the liver. For heavy drinkers, it can cause alcoholic hepatitis, fatty liver, and cirrhosis. Alcohol is pungent and hot, with an irritant effect, it can dilate blood vessels, accelerate blood flow, and also cause gastritis and the recurrence of gastrointestinal ulcers. Leeks are also pungent and warm in nature, and can invigorate yang and promote blood circulation. Eating raw leeks and drinking baijiu is like adding fuel to the fire. Long-term consumption can disturb the blood, and patients with bleeding diseases should be especially cautious.
