隔食病 津液干 方书名膈者，以病在膈上是也。又名隔者，以食物不下而阻隔也。津
液干枯为隔食病源。
胃脘闭 谷食难 胃脘干枯闭小，水饮可行，食物难下。
时贤法 左归餐 赵养葵用大剂六味汤主之。高鼓峰仿赵养葵之法以六味加生地、当归
主之。杨乘六用左归饮去茯苓，加当归、生地。以左归饮中有甘草引入阳明，开展胃阴。去
茯苓者，恐其旁流入坎，不如专顾阳明之速效也。
胃阴展 贲门宽 如膏如脂，叠积胃底，即胃阴也。久隔之人，则胃阴亡矣。高鼓峰
云∶治隔一阳明尽之，阳明者胃也。但使胃阴充拓，在上之贲门宽展，则食物入；在下之幽
门、阑门滋润，则二便不闭，而隔症愈矣。
启膈饮 理一般 启膈饮亦是和胃养阴之意。但此方泄肺气之郁，彼方救肾水之枯，一
阴一阳，宜择用之。
推至理 冲脉干 张石顽云∶膈咽之间，交通之气不得降者，皆冲脉上行，逆气所作也。
大半夏 加蜜安 冲脉不治，取之阳明。仲景以半夏降冲脉之逆，即以白蜜润阳明之燥
，加人参以生既亡之津液，用甘澜水以降逆上之水液。古圣之经方，惟仲景知用之。
金匮秘 仔细看 《金匮》明明用半夏，后人诸书，皆以半夏为戒。毁圣之说，倡自何人?君子恶之!
若反胃 实可叹 食得入而良久反出，名为反胃。
朝暮吐 分别看 朝食暮吐，暮食朝吐，与隔食症宜分别而药之。
乏火化 属虚寒 王太仆云∶食不得入，是有火也。食入反出，是无火也。此症属中焦
、下焦火衰无疑。
吴萸饮 独附丸 妙在吴萸镇厥阴逆气，配入甘温，令震坤合德，土木不害。生附子以
百沸汤俟温，浸去盐，日换汤三次。三日外去皮，放地上，四面以砖围，外以炭火烧一时，
则附子尽裂，乘热投以姜汁，又如法制之。大抵一斤附子配一斤姜汁，以姜汁干为度，研末
蜜丸。以粟米稀粥，送下二钱。
六君类 俱神丹 六君子汤加姜附及附子理中汤之类。
隔食病，是由于津液干枯所致。方书之所以将这种病称为“膈”，是因为病变部位在膈肌之上；又被称为“隔”，是因为食物下咽时发生阻隔、无法下行。津液的枯竭干涸，是隔食病的根本病因。
胃脘部干枯闭塞，导致容积变小，此时水饮尚能通行，但固体食物难以吞咽下去。
当代医家多采用左归饮这一方剂进行治疗。赵养葵使用大剂量的六味地黄汤作为主方。高鼓峰效仿赵养葵的方法，在六味地黄汤基础上加入生地黄和当归来主治此病。杨乘六则使用左归饮，去掉茯苓，加入当归和生地黄。因为在左归饮中含有甘草，可以引导药力进入阳明经，从而舒展胃阴；而去掉茯苓的原因，是担心其药性旁流入肾（坎），不如专门顾护阳明经来得迅速有效。
当胃阴得以舒展时，贲门就会变得宽松。所谓胃阴，就像膏脂一样，堆积在胃底。长期患有隔食病的人，胃阴已经耗竭。高鼓峰说：治疗隔食病，关键在于调理阳明经，因为阳明经对应的脏腑就是胃。只要使胃阴充足并得到扩充，上部的贲门就能宽展，食物便能顺利进入；下部的幽门和阑门得到滋润，二便就不会闭塞，这样隔食的症状就能痊愈。
启膈饮的治疗原理与此类似，也是调和胃气、滋养阴液的意思。但是，启膈饮侧重于宣泄肺气的郁结，而前述方剂侧重于挽救肾水的枯涸，一阴一阳，应当根据具体情况选择使用。
推究其深层道理，这与冲脉的干枯有关。张石顽说：膈部和咽部之间，交通的气机不能下降，都是由于冲脉之气上行，逆气作祟所致。
对于冲脉之气上逆，如果不治，可取法于阳明经。张仲景用半夏来降泄冲脉的逆气，同时用白蜜来润燥阳明经，加入人参以生津液，补充已经亡失的津液，使用甘澜水来降逆上行的水液。古代圣人的经典方剂，只有张仲景懂得如何运用。
《金匮要略》中明明记载使用半夏，后世的许多书籍却都告诫禁用半夏。诋毁圣人学说的说法，是谁倡导的？君子对此深恶痛绝！
如果是反胃症，实在令人叹息。食物能够吃进去，但过了很久又吐出来，这叫做反胃。
朝食暮吐或暮食朝吐的情况，需要与隔食症加以区分，并分别用药治疗。
这类病症缺乏火气的温化，属于虚寒证。王太仆说：食物吃不下进去，是有火邪；食物吃进去后又吐出来，是没有火气。此症无疑属于中焦和下焦的火衰。
吴茱萸饮和独附丸是常用的方剂。妙处在于吴茱萸能镇摄厥阴肝经的逆气，配合甘温的药物，使得震卦（肝/木）与坤卦（脾/土）和谐共处，土木不相害。制作独附丸时，取生附子，用滚开水浸泡至温度适宜，浸去盐分，每天更换三次水。三天后去皮，放在地上，四周用砖围住，外面用炭火烧一个时辰，直到附子完全裂开，趁热投入姜汁，再按照同样的方法处理。大致上一斤附子配一斤姜汁，以姜汁被吸干为度，研成粉末，用蜂蜜制成丸剂。服用时用小米稀粥送服二钱。
Ge Shi Disease (Food Obstruction) arises from the dryness and depletion of Body Fluids. Medical texts refer to this condition as "Ge" (Diaphragm) because the pathology is located above the diaphragm; it is also called "Ge" (Obstruction) because food cannot pass down due to blockage. The withering and drying up of Body Fluids is the root cause of Ge Shi Disease.
When the stomach region becomes dry, closed, and narrowed, liquids may still pass through, but solid food is difficult to swallow.
Contemporary physicians often employ the method of Zuo Gui Yin (Left Return Decoction). Zhao Yangkui used a large dose of Liu Wei Di Huang Tang (Six-Ingredient Rehmannia Decoction) as the primary formula. Gao Gufeng imitated Zhao Yangkui’s method, treating the condition with Liu Wei Di Huang Tang supplemented by Sheng Di Huang (Rehmanniae Radix Recens) and Dang Gui (Angelicae Sinensis Radix). Yang Chengliu used Zuo Gui Yin, removing Fu Ling (Poria) and adding Dang Gui and Sheng Di Huang. This is because Zuo Gui Yin contains Gan Cao (Licorice Root), which guides the medicinal action into the Yangming channel to expand Stomach Yin. Fu Ling was removed to prevent its effect from diverting into the Kidney (Kan trigram); focusing solely on the Yangming channel yields faster results.
When Stomach Yin is expanded, the cardia (Bumen) widens. Stomach Yin is likened to grease or fat, accumulating at the bottom of the stomach. In cases of chronic obstruction, Stomach Yin has been exhausted. Gao Gufeng stated: "Treating Ge involves addressing only the Yangming channel, for Yangming corresponds to the Stomach." If Stomach Yin is sufficiently replenished and expanded, the upper Bumen (cardia) will widen, allowing food to enter; if the lower Youmen (pylorus) and Lanmen are moistened, bowel movements and urination will not be obstructed, and the symptoms of Ge will resolve.
Qi Ge Yin (Open the Diaphragm Decoction) shares the same principle of harmonizing the Stomach and nourishing Yin. However, Qi Ge Yin focuses on dispersing Lung Qi stagnation, whereas the aforementioned formulas focus on rescuing depleted Kidney Water. One addresses Yin, the other Yang; selection should be made based on the specific presentation.
Examining the underlying logic, this relates to the dryness of the Chong Mai (Penetrating Vessel). Zhang Shiwan stated: "The qi that facilitates communication between the diaphragm and throat fails to descend due to the ascending of the Chong Mai and the rebellion of Qi."
If the Chong Mai is not treated, one may resort to the Yangming channel. Zhang Zhongjing used Ban Xia (Pinelliae Rhizoma) to subdue the rebellious Qi of the Chong Mai, Bai Mi (White Honey) to moisten the dryness of the Yangming channel, Ren Shen (Ginseng Radix) to generate lost Body Fluids, and Gan Lan Shui (Water Boiled in a Ladle) to descend the rebellious fluids. Among the ancient sage's classic prescriptions, only Zhang Zhongjing knew how to apply them correctly.
Jin Gui Yao Lue (Essential Prescriptions from the Golden Cabinet) clearly records the use of Ban Xia, yet later texts warn against its use. Who initiated these slanderous remarks against the sages? Gentlemen detest such behavior!
Regarding Fan Wei (Regurgitation), it is truly lamentable. When food enters but is vomited out after a long interval, it is termed Fan Wei.
Morning and Evening Vomiting must be distinguished. Vomiting what was eaten in the morning in the evening, or vice versa, requires differentiation from Ge Shi Disease and distinct pharmacological treatment.
This condition lacks the transformational power of Fire and belongs to Deficiency-Cold. Wang Tai pu said: "Inability to ingest food indicates the presence of Fire; vomiting food after ingestion indicates the absence of Fire." This condition undoubtedly stems from the decline of Fire in the Middle and Lower Jiao.
Wu Yu Yin (Evodia Drink) and Du Fu Wan (Single Aconite Pill) are notable. Their efficacy lies in Wu Zhu Yu (Evodiae Fructus) suppressing the rebellious Qi of the Jueyin Liver channel, combined with sweet-warm herbs to harmonize Zhen (Liver/Wood) and Kun (Spleen/Earth), preventing mutual harm. For preparing Du Fu Wan, raw Fu Zi (Aconiti Lateralis Radix Preparata) is soaked in boiling water until warm to remove salt, changing the water three times daily. After three days, the skin is peeled off, the herb is placed on the ground surrounded by bricks, and fired with charcoal for one hour until the Aconite cracks completely. While hot, Ginger Juice is added, and the process is repeated. Generally, one jin of Aconite is paired with one jin of Ginger Juice, processed until the juice is absorbed, then ground into powder and formed into pills with honey. These are taken with millet thin gruel, two qian per dose.
Formulas similar to Liu Jun Zi Tang (Six-Gentleman Decoction), including those augmented with Sheng Jiang (Zingiberis Rhizoma Recens) and Fu Zi, as well as Fu Zi Li Zhong Tang (Aconite Regulate the Middle Decoction), serve as miraculous elixirs for such conditions.
