或问东垣曰∶生姜辛温入肺，如何是入胃口？曰∶俗皆以心下为胃口者，非也。咽门之
下，受有形之物，系胃之 ，便为胃口。与肺同处，故入肺而开胃口也。又问曰∶人云∶夜
间勿食生姜，食则令人闭气，何也？曰∶生姜辛温，主开发，夜则气本收敛，反食之开发其
气，则违天道，是以不宜食，此以平人论之可也。若有病则不然。姜屑比之干姜，不热；比
之生姜，不润。以干生姜代干姜者，以其不僭故也。

有人问李东垣说：生姜辛温入肺，怎么说是入胃口？回答说：世俗都把心下当作胃口，是不对的。咽门之下，接受有形之物，属于胃的部分，便称为胃口。与肺处于同一位置，所以入肺而开胃口。又问：有人说：夜间不要吃生姜，吃了会让人闭气，为什么？回答说：生姜辛温，主开发，夜间气本应收敛，反而吃它来开发其气，就违背天道，所以不宜吃，这是针对普通人而言的。如果有病则不然。姜屑比起干姜，不那么热；比起生姜，不那么润。用干生姜代替干姜，是因为它不僭越的缘故。
《汤液本草·本草》说：秦椒是它的使药。能杀半夏、莨菪的毒。厌恶黄芩、黄连、天鼠粪。

*Tangye Bencao · Bencao* states: It treats limb pain, hemiplegia with numbness, and necrotic muscle. It removes dark moles and malignant diseases, stops diarrhea, reduces excessive salivation and dry mouth, and clears heat from between the bones. Another prescription treats all kinds of malignant sores with protruding flesh; burn the Wumei (Mume Fruit) to ash, pound into powder, and apply topically, causing the malignant flesh to fall off immediately.

Enters the Hand and Foot Taiyin Meridians.
*Tangye Bencao · Bencao* states: It treats jiaogqi (foot disease) with damp-bi, evil Qi Huoluan (cholera-like syndrome), severe vomiting and diarrhea, and continuous muscle cramps. It benefits the Lung and dispels dampness, harmonizes the Stomach and nourishes the Spleen.
*Yanyi* states: Mugua (Chaenomeles Fruit) obtains the upright Qi of Wood, thus entering the sinews. When coated with Qianbaishuang (Lead White Frost), it loses its sour taste due to Metal controlling it. This substance enters the Liver, thus benefiting sinews and blood. For conditions of weakness in the lower back, kidneys, feet, and knees, this substance is indispensable.
*Dongyuan* states: When Qi escapes, it can astringe; when Qi stagnates, it can harmonize.
*Leigong* states: It regulates Ying and Wei (Defensive and Nutritive Qi) and assists Guqi (Grain Qi).
*Shixi* states: The root bark is very cold, governing xiaoke (wasting-thirst), stopping mental restlessness, and reversing Ben Tun (rushing pig) Qi. Zhang Zhongjing uses it in Bentun Tang (Rushing Pig Decoction).
Qi is warm, taste is pungent and bitter.
*Tangye Bencao · Bencao* states: It repels evil toxins, promotes blood vessels, and unblocks deficient Qi of the Five Zang Organs. It induces sweating and eliminates fatigue-thirst. Pound it, mix with vinegar, and apply to toxic swellings. Remove branches and stems, crush by hand for use; it is miraculous for treating postpartum blood fainting. It may induce thirst. Eating too much smokes the spirits of the Five Zang Organs. It breaks up stagnant Qi.
Qi is warm, taste is pungent. Pungent and sweet, slightly warm, the Qi and Taste are both light, belonging to Yang. Non-toxic.
*Tangye Bencao · Xiang* states: It treats Shanghan (Cold Damage) headache and nasal congestion, cough with rebellious Qi. It stops vomiting and treats phlegm-cough. Raw and dried forms are treated similarly. Used in equal parts with Banxia (Pinellia Rhizome), it treats acute pain below the heart; decoct finely.
*Tangye Bencao · Xin* states: It can counteract the toxicity of Banxia and Houpo (Magnolia Bark). It disperses Wind-Cold, benefits Yuan Qi (Primal Qi); use together with Dazao (Jujube Fruit).

*Zhen* states: It benefits the Spleen and Stomach, disperses Wind-Cold. Long-term use removes bad breath and clarifies the spirit.
Sun Simiao states: It is the supreme medicine for vomiting syndromes.
Someone asked Dongyuan: "Shengjiang (Fresh Ginger) is pungent and warm and enters the Lung; how is it said to enter the Stomach opening?" He replied: "The common people mistake the area below the heart for the Stomach opening; this is incorrect. Below the pharynx, where solid food enters, belonging to the Stomach, is called the Stomach opening. Since it shares location with the Lung, it enters the Lung and opens the Stomach opening." Asked again: "People say: Do not eat Shengjiang at night, as it causes Qi obstruction. Why?" He replied: "Shengjiang is pungent and warm, primarily promoting development. At night, Qi naturally converges; eating it to promote development violates the Heavenly Way, hence it is unsuitable. This applies to healthy individuals. If there is illness, it is different. Jiangxie (Ginger residue) is less hot than Ganjiang (Dried Ginger) but less moistening than Shengjiang. Using Ganshengjiang (Sun-dried Ginger) instead of Ganjiang is because it is not overly acrid."
*Tangye Bencao · Bencao* states: Qinjiao (Sichuan Pepper) is its Shi (Assistant/Guide). It kills the toxicity of Banxia and Langdang (Datura Seed). It is adverse to Huangqin (Scutellaria Root), Huanglian (Coptis Rhizome), and Tianshufen (Sky Rat Feces).
