酒，取“酉”字之意。用米和曲酿造而成，经过长时间发酵味道变得甜美。味辛的酒，具有发散作用，能作为引导药力通行的媒介，可以通行全身体表，到达身体最高最远的部位；味苦的酒，具有下行作用；味甘的酒，居于中焦而作用缓和；味淡的酒，能通利小便且使药力迅速下行。陶隐居说：大寒时节海水凝结，只有酒不会结冰，说明其性质非常热。酒能大补肝、滋养脾，充实肠胃，润泽皮肤，疏散胸中的郁结之气，活血通络以消除肢体间的瘀血，破除积聚的痞块。它能增强药势，引导药物进入各条经络，效果与附子相似。酒能杀灭各种邪气恶毒瓦斯，抵御风寒雾露。过去有三个人在早晨雾气中行走，空腹的人死了，吃粥的人病了，喝酒的人却健康无恙。这就是酒能辟除邪气的例子。《东垣十书》中说：
Jiu (Alcohol/Wine) is derived from the character "You" (酉). It is brewed using rice and Qu (fermented starter), and its flavor becomes mellow and sweet after prolonged fermentation. The pungent taste allows for dispersion; it serves as a guiding agent, capable of circulating through the exterior of the entire body, reaching the highest and most distant parts. The bitter taste facilitates downward movement. The sweet taste resides in the middle and acts gently. The bland taste promotes urination and causes rapid downward action. Tao Hongjing stated: "When severe cold freezes the seas, only wine does not freeze," indicating its intense heat nature. Wine greatly supports the Liver and nourishes the Spleen, thickens the stomach and intestines, moistens the skin, disperses stagnant Qi in the chest, invigorates blood circulation to resolve stagnation in the limbs, and breaks up masses (Pi 癖). It enhances the potency of medicinal herbs, guides them into various meridians without limit, similar to Fuzi (Aconite Lateralis Radix Praeparata). It kills various evil toxins and noxious vapors, and protects against wind-cold, fog, and dew. In ancient times, three individuals walked in the morning mist; the one who was fasting died, the one who ate porridge fell ill, but the one who drank wine remained healthy. This illustrates the ability of wine to ward off evil influences. The *Dongyuan Shishu* (Ten Books of Dongyuan) states:
