Ju Pi Zhu Ru Tang (橘皮竹茹汤), known in English as Tangerine Peel and Bamboo Shavings Decoction, is a classical TCM formula for clearing Stomach heat and descending rebellious Qi. It is particularly indicated for nausea, vomiting, hiccups, epigastric discomfort, and acid reflux due to Stomach heat with Qi rebellion, often seen in morning sickness, chemotherapy-induced nausea, gastritis, and hyperacidity. In modern clinical practice, Ju Pi Zhu Ru Tang is used for heat patterns in the Stomach causing upward rebellion of Qi. By clearing Stomach heat while descending rebellious Qi and harmonizing the Stomach, it effectively relieves nausea, vomiting, and epigastric discomfort caused by Stomach heat with Qi rebellion.

I. Origins and History

1. Legend of Origins

The origins of Ju Pi Zhu Ru Tang can be traced to antiquity. According to legend, long ago there was an elderly man who often suffered from epigastric fullness and distension, nausea, and vomiting, with little appetite for food. He tried various remedies without improvement. One day, a travelling physician passed by, listened carefully to the elderly man's symptoms, reflected at length, and prescribed a formula. The physician selected the commonly available Jupi (Tangerine Peel) and Zhuru (Bamboo Shavings), combined them with several other herbs, and instructed the old man to decoct and drink the preparation. After taking it, his symptoms gradually diminished and his appetite slowly recovered. This formula represented the prototype of Ju Pi Zhu Ru Tang — and though the legend carries a touch of the mystical, it reflects the ancient physicians' exploration of illness through long-term medical practice.

2. Classical Records

In the classical canon of Chinese medicine, Ju Pi Zhu Ru Tang has clear documentation. It first appears in the Jin Gui Yao Lue (Essential Prescriptions of the Golden Cabinet) by Zhang Zhongjing of the late Eastern Han dynasty. The Jin Gui Yao Lue is China's earliest medical monograph dedicated to miscellaneous diseases and has exerted a far-reaching influence on the subsequent development of Chinese medicine. The text records: "Ju Pi Zhu Ru Tang treats hiccough and counterflow." In just a few concise words, the formula's primary indication is clearly stated as hiccough — what we now call ènì, the upward counterflow of qi with repeated hiccoughing sounds in the throat, short and frequent, unable to stop on its own. This record provided important precedent for later physicians employing Ju Pi Zhu Ru Tang to treat hiccough and related conditions.

3. Historical Evolution

Over time, Ju Pi Zhu Ru Tang has been continuously applied and developed through the clinical practice of physicians across successive generations. Physicians of different dynasties made appropriate adjustments and additions to the formula based on their own experience and understanding of disease — including changes in herb dosages, processing methods, and combination strategies. Some physicians incorporated additional herbs into the original formula to enhance its efficacy, making it progressively more refined. This historical evolution reflects the flexibility and adaptability of Chinese medicine formulas in the process of transmission, continuously keeping pace with the times to better address diverse conditions.

II. Herb Composition (Sovereign, Minister, Assistant, Envoy)

1. Chief Herb — Jupi (Tangerine Peel)

Flavour, Nature and Channel Tropism

Jupi is acrid and bitter in flavour and warm in nature, entering the Spleen and Lung channels. Its acridity enables it to move and disperse; its bitterness enables it to descend and drain; its warmth enables it to disperse cold. Entering the Spleen and Lung channels, it can regulate qi and strengthen the spleen, dry dampness and transform phlegm.

Actions

It has the action of regulating qi and strengthening the spleen, capable of adjusting the qi movement of the spleen and stomach to ensure their qi flows smoothly. It produces excellent relief of symptoms such as epigastric fullness and distension, belching, nausea, and vomiting caused by spleen-stomach qi stagnation. Simultaneously, Jupi can also dry dampness and transform phlegm, and may be used to treat cough with profuse phlegm and related conditions. In Ju Pi Zhu Ru Tang, Jupi serves as the chief herb with the primary role of regulating qi, harmonising the stomach, and directing counterflow downward — targeting symptoms such as hiccough caused by stomach qi counterflowing upward, and effectively regulating stomach qi to descend, thereby relieving the condition.

2. Deputy Herb — Zhuru (Bamboo Shavings)

Flavour, Nature and Channel Tropism

Zhuru is sweet in flavour and slightly cold in nature, entering the Lung and Stomach channels.

Actions

Zhuru has the actions of clearing heat and transforming phlegm, and relieving vexation and stopping vomiting. It clears stomach heat to arrest vomiting and counterflow, producing good therapeutic results for vomiting and hiccough caused by stomach heat. Simultaneously, its heat-clearing and phlegm-transforming action assists Jupi in regulating qi and transforming phlegm, reinforcing the formula's overall phlegm-transforming and stomach-harmonising potency. In Ju Pi Zhu Ru Tang, Zhuru serves as the deputy herb, assisting the chief herb Jupi in reinforcing the action of directing counterflow downward and stopping vomiting, and producing a heat-clearing and counterflow-descending effect against hiccough caused by stomach heat.

3. Assistant Herb — Shengjiang (Fresh Ginger)

Flavour, Nature and Channel Tropism

Shengjiang is acrid in flavour and slightly warm in nature, entering the Lung, Spleen, and Stomach channels.

Actions

Shengjiang has the actions of releasing the exterior and dispersing cold, warming the middle to stop vomiting, and warming the lungs to relieve cough. In Ju Pi Zhu Ru Tang, Shengjiang primarily exerts its middle-warming and vomiting-stopping action. It reinforces the yang qi of the spleen and stomach, drives out cold pathogen, and relieves the discomfort of cold in the epigastric region. Combined with Jupi and Zhuru, it jointly regulates the stomach qi and reinforces the vomiting-stopping effect. Simultaneously, the acrid-dispersing nature of Shengjiang also promotes the exertion of other herbs' medicinal force, enabling the entire formula to work more effectively.

4. Assistant Herb — Dazao (Jujube)

Flavour, Nature and Channel Tropism

Dazao is sweet in flavour and warm in nature, entering the Spleen, Stomach, and Heart channels.

Actions

Dazao has the actions of tonifying the middle and boosting qi, and nourishing blood and calming the spirit. In the formula, Dazao tonifies the spleen and boosts qi; combined with Shengjiang, it reinforces the spleen and stomach's transforming and transporting function, providing the support of the postnatal root for the entire formula. Simultaneously, Dazao harmonises all the herbs, moderating the potency of the other medicinals and making the formula's medicinal nature more balanced and harmonious, thereby coordinating the sovereign, minister, assistant, and envoy herbs so they work together to produce the therapeutic effect.

5. Envoy Herb — Gancao (Licorice Root)

Flavour, Nature and Channel Tropism

Gancao is sweet in flavour and neutral in nature, entering the Heart, Lung, Spleen, and Stomach channels.

Actions

Gancao has the actions of tonifying the spleen and boosting qi, moistening the lungs to relieve cough, clearing heat and resolving toxicity, and harmonising all the herbs. In Ju Pi Zhu Ru Tang, Gancao primarily exerts its harmonising action. It coordinates the medicinal nature of all herbs in the formula so they work together synergistically, jointly exerting the actions of regulating qi, harmonising the stomach, directing counterflow downward, and stopping vomiting. Simultaneously, Gancao also provides a degree of spleen-tonifying and qi-boosting action, assisting Dazao in strengthening spleen and stomach function, maintaining the body's righteous qi and facilitating recovery from illness.

III. Pathomechanism, Actions, and Indications

1. Pathomechanism Analysis

The pathomechanism targeted by Ju Pi Zhu Ru Tang is primarily stomach deficiency with heat and failure of qi to descend. The stomach governs the reception and ripening of food and water, and stomach qi functions optimally when descending. When the stomach is deficient, the stomach's function weakens and transformation and transport become disordered; and the presence of heat causes the stomach fluids to be scorched, leading to stomach qi counterflowing upward. This intertwining of stomach deficiency and stomach heat readily gives rise to upward qi counterflow and the appearance of hiccough and related symptoms. For example, some people who have long suffered from irregular eating habits and excessive fatigue may have injured their stomach qi; combined with emotional constraint, liver qi stagnation transforming into fire, and the liver fire counterflowing horizontally to invade the stomach — deficiency-heat arises within the stomach, stomach qi counterflows upward, and frequent hiccough, epigastric fullness and distension, dry bitter mouth, and related symptoms appear. This is precisely the pathomechanism presentation for which Ju Pi Zhu Ru Tang is indicated.

2. Actions

Based on the above pathomechanism, Ju Pi Zhu Ru Tang has the actions of regulating qi and directing counterflow downward, and clearing heat and harmonising the stomach. Within the formula, Jupi regulates qi, harmonises the stomach, and directs counterflow downward; Zhuru clears heat, transforms phlegm, relieves vexation, and stops vomiting. The two combined — one warm, one cold; one regulating qi, one clearing heat — target the pathomechanism of stomach deficiency with heat and failure of qi to descend, jointly producing the action of regulating stomach qi, clearing heat, and directing counterflow downward. Shengjiang warms the middle and stops vomiting; Dazao and Gancao tonify the spleen and boost qi and harmonise all the herbs — all jointly assisting the chief and deputy herbs, so that the entire formula both regulates qi and directs counterflow downward and clears heat and harmonises the stomach, restoring the normal ascending and descending function of the stomach qi.

3. Indications

Ju Pi Zhu Ru Tang is primarily indicated for hiccough due to stomach deficiency with heat — with short, discontinuous hiccough sounds, dry mouth and tongue, a burning sensation in the epigastric region, vexing restlessness, and possibly vomiting. In clinical practice, for patients whose hiccough results from irregular diet, emotional disturbance, or prolonged illness and bodily debility giving rise to stomach deficiency with heat, Ju Pi Zhu Ru Tang often achieves good therapeutic results. In addition, for morning sickness (hyperemesis gravidarum) of the stomach deficiency with heat type, this formula may also be used. Morning sickness refers to the nausea, vomiting, dizziness, and aversion to food that arise in early pregnancy; when the pattern is identified as stomach deficiency with heat, Ju Pi Zhu Ru Tang can relieve the symptoms of morning sickness and safeguard the health of both mother and fetus by regulating qi, harmonising the stomach, clearing heat, and directing counterflow downward.

IV. Formula Analysis

1. Regulating Qi, Harmonising the Stomach and Directing Counterflow Downward

Jupi is acrid-warm and can regulate qi, strengthen the spleen, harmonise the stomach, and direct counterflow downward — serving as the chief herb. It is skilled at unravelling spleen-stomach qi stagnation and causing stomach qi to descend, thereby relieving symptoms of stomach qi counterflowing upward such as hiccough. Zhuru is cold in nature and clears heat, transforms phlegm, relieves vexation, and stops vomiting — assisting Jupi in clearing heat and directing counterflow downward in the stomach as the deputy herb. The two combined — one warm, one cold; one regulating qi, one clearing heat — jointly produce the action of regulating qi, harmonising the stomach, and directing counterflow downward against the pathomechanism of stomach deficiency with heat and failure of qi to descend. Shengjiang, warm in nature, warms the middle, stops vomiting, and disperses cold, reinforcing the stomach-harmonising and counterflow-descending potency; Dazao and Gancao tonify the spleen and boost qi and harmonise all the herbs, enabling the entire formula to simultaneously regulate qi and direct counterflow downward while protecting the spleen and stomach righteous qi, preventing excessive medication from damaging the righteous.

2. Simultaneous Use of Heat-Clearing and Yang-Warming

Within the formula, Zhuru clears heat to target deficiency-heat within the stomach, whilst Shengjiang warms yang to address stomach deficiency with cold. These seemingly opposing medicinal natures are in fact mutually complementary. Stomach deficiency with heat readily causes stomach qi counterflowing upward; clearing heat alone may damage stomach yang, whilst warming yang alone may assist stomach heat. The combination of Zhuru and Shengjiang clears heat without cold-suppressing stomach yang, and warms yang without reinforcing stomach heat, allowing the cold and heat within the stomach to reach a balance and the stomach qi to ascend and descend normally. This method of simultaneously using heat-clearing and yang-warming embodies the subtlety of Chinese medicine formula composition, capable of precisely regulating the body's yin-yang balance and treating conditions of stomach deficiency with heat and failure of qi to descend.

3. Harmonising the Spleen and Stomach and Supporting the Righteous

Dazao and Gancao tonify the spleen and boost qi and harmonise all the herbs. The spleen and stomach are the postnatal root and the source of qi-blood generation. In treating the condition of stomach deficiency with heat and failure of qi to descend, tonifying the spleen and boosting qi strengthens the transforming and transporting function of the spleen and stomach, facilitating the recovery of the righteous qi. Simultaneously, Gancao harmonises all the herbs, enabling the medicinal nature of each herb in the formula to be mutually coordinated and to exert their therapeutic effects more effectively. Supporting the righteous and expelling the pathogen together — eliminating the condition through regulating qi, directing counterflow downward, and clearing heat and harmonising the stomach on one hand, whilst protecting the spleen-stomach righteous qi through tonifying the spleen and boosting qi on the other — allowing the body to recover its health as rapidly as possible after treatment. This embodies the Chinese medicine treatment principles of treating the root cause and simultaneously supporting the righteous and expelling the pathogen.

V. Comparison with Related Formulas

1. Comparison with Dingxiang Shidi Tang

Compositional and Functional Differences

Dingxiang Shidi Tang is composed of Dingxiang (Cloves), Shidi (Persimmon Calyx), Renshen (Ginseng), and Shengjiang (Fresh Ginger), with the primary action of warming the middle and directing counterflow downward. Its targeted pathomechanism is stomach-cold hiccough, centred on stomach deficiency-cold. Within the formula, Dingxiang and Shidi warm the stomach and disperse cold, descend qi and arrest hiccough; Renshen tonifies qi and supports the righteous; Shengjiang warms the stomach and disperses cold. Ju Pi Zhu Ru Tang, by contrast, is primarily indicated for hiccough due to stomach deficiency with heat, with the actions of regulating qi and directing counterflow downward, and clearing heat and harmonising the stomach. In terms of composition, Dingxiang Shidi Tang centres on warm-natured herbs and emphasises warming the middle, whereas Ju Pi Zhu Ru Tang contains both cold and warm herbs, emphasising clearing heat, harmonising the stomach, and regulating qi.

Distinguishing Indications

Dingxiang Shidi Tang is suited to stomach-cold hiccough symptoms — hiccough sounds that are deep, slow, and forceful, epigastric discomfort, reduction of symptoms with warmth, and a bland tasteless mouth without thirst. For example, some people develop stomach-cold hiccough from excessive consumption of raw and cold foods, and in such cases Dingxiang Shidi Tang is the more appropriate choice. Ju Pi Zhu Ru Tang is suited to stomach deficiency with heat hiccough symptoms — hiccough sounds that are short and discontinuous, dry mouth and tongue, and a burning sensation in the epigastric region. For instance, those who frequently stay up late and suffer from emotional constraint, developing hiccough from stomach deficiency with heat, are better suited to treatment with Ju Pi Zhu Ru Tang.

2. Comparison with Xuanfu Daizhe Tang

Herb Composition Characteristics

Xuanfu Daizhe Tang is composed of Xuanfuhua (Inula Flower), Daizhe Shi (Haematite), Banxia (Pinellia), Renshen (Ginseng), Gancao (Licorice Root), Shengjiang (Fresh Ginger), and Dazao (Jujube). Xuanfuhua descends qi and transforms phlegm; Daizhe Shi heavily settles and directs counterflow downward — the two combined reinforce the counterflow-descending and phlegm-transforming potency. Banxia dries dampness and transforms phlegm; Renshen, Gancao, and Dazao tonify the spleen and boost qi. Compared with Ju Pi Zhu Ru Tang, Xuanfu Daizhe Tang places greater emphasis on directing counterflow downward and transforming phlegm, with a stronger counterflow-descending potency, whilst also addressing spleen-stomach qi deficiency. Ju Pi Zhu Ru Tang focuses primarily on regulating qi, harmonising the stomach, and clearing heat to direct counterflow downward, with a stronger heat-clearing potency, emphasising the regulation of the pathomechanism of stomach deficiency with heat and failure of qi to descend.

Differing Clinical Emphasis

Xuanfu Daizhe Tang is commonly used to treat epigastric glomus and fullness, belching, and hiccough caused by stomach qi deficiency, interior obstruction by phlegm turbidity, and failure of qi to descend — particularly suited to hiccough arising from phlegm-qi mutual obstruction. For example, patients with a weak spleen and stomach who also have interior phlegm-dampness obstruction presenting with hiccough, epigastric fullness and distension, and nausea and vomiting are better suited to Xuanfu Daizhe Tang. Ju Pi Zhu Ru Tang is primarily used for hiccough due to stomach deficiency with heat, and is more appropriate for hiccough where there is simple stomach deficiency with heat and no pronounced interior phlegm turbidity obstruction — such as hiccough in the late stage of a febrile disease where the stomach yin has been damaged with residual heat lingering, where Ju Pi Zhu Ru Tang can clear heat and harmonise the stomach to relieve symptoms.

VI. Clinical Applications

1. Hiccough

Key Pattern Differentiation Points

For patients with hiccough, the first step in using Ju Pi Zhu Ru Tang is to determine whether the presentation corresponds to the pattern of stomach deficiency with heat. In addition to short, discontinuous hiccough sounds, one should also observe whether the patient has dry mouth and tongue, a burning sensation in the epigastric region, and vexing restlessness. If accompanied by a red tongue with scant coating and a thin and rapid pulse reflecting yin deficiency with heat, this further supports the pattern identification of stomach deficiency with heat. For example, a patient with frequent hiccough, vague aching pain in the epigastric region, dry and bitter mouth, vexing restlessness with insomnia, a red tongue with scant coating, and a thin and rapid pulse may be comprehensively assessed as hiccough due to stomach deficiency with heat, for which Ju Pi Zhu Ru Tang may be considered.

Therapeutic Outcomes

Clinical practice has shown that for hiccough patients whose pattern corresponds to stomach deficiency with heat, Ju Pi Zhu Ru Tang often achieves good therapeutic results. After taking several doses, the hiccough symptoms typically diminish markedly and the epigastric discomfort gradually resolves. For example, one patient with hiccough from stomach deficiency with heat caused by emotional constraint showed a marked decrease in hiccough frequency after taking three doses of Ju Pi Zhu Ru Tang; the epigastric fullness and distension resolved; and the symptoms were essentially cured after taking several additional doses.

2. Morning Sickness (Hyperemesis Gravidarum)

Pattern Differentiation and Herb Selection

When morning sickness is identified as the pattern of stomach deficiency with heat, Ju Pi Zhu Ru Tang may also be applied. In addition to nausea and vomiting, there will also be manifestations such as dry mouth, a bitter taste in the mouth, and a burning sensation in the epigastric region. Within the formula, Jupi and Zhuru regulate qi, harmonise the stomach, clear heat, and direct counterflow downward; Shengjiang warms the middle and stops vomiting; Dazao and Gancao tonify the spleen and boost qi — the formula both relieves morning sickness symptoms and protects the pregnant woman's righteous qi, ensuring normal fetal development. For example, a pregnant woman who in early pregnancy developed severe nausea and vomiting accompanied by a bitter taste in the mouth and epigastric discomfort, with a red tongue and yellow coating and a slippery and rapid pulse, was identified as morning sickness due to stomach deficiency with heat; after taking Ju Pi Zhu Ru Tang, her symptoms gradually resolved, vomiting frequency decreased, and her diet improved.

Precautions

When using Ju Pi Zhu Ru Tang to treat morning sickness, attention must be paid to the dosage and method of administration. As the physiological condition of pregnant women is unique, medication requires particular caution. In general, herb dosages should be adjusted appropriately under medical supervision according to the specific condition of the pregnant woman. Simultaneously, close monitoring of changes in the pregnant woman's symptoms and the fetal condition is necessary to ensure safe and effective use.

VII. Clinical Modifications

1. Pronounced Stomach Heat

When stomach heat is more pronounced, the dosage of Zhuru may be increased to reinforce the heat-clearing potency. Zhuru itself clears heat and transforms phlegm, relieves vexation and stops vomiting; increasing its dosage allows more effective clearing and draining of stomach heat, relieving symptoms such as a burning sensation in the epigastric region and vexing restlessness. For example, where the original formula uses 10 g of Zhuru, those with pronounced stomach heat may increase this to 15–20 g. Simultaneously, Huanglian (Coptis Root) 3–5 g may be added; Huanglian is bitter and cold and can directly break the stomach heat; acting synergistically with Zhuru, it reinforces the heat-clearing effect.

2. Pronounced Counterflow of Qi

When qi counterflow is more pronounced, the dosage of Jupi may be increased to reinforce the qi-regulating and counterflow-descending action. Jupi regulates qi and strengthens the spleen, harmonises the stomach and directs counterflow downward; increasing the dosage enables more effective unravelling of the stomach qi, allowing the qi counterflow to be relieved. The original Jupi dosage may be increased from 12 g to 15–18 g. Zhike (Bitter Orange Fruit) 10–12 g may also be added; Zhike moves qi and widens the centre, and combined with Jupi reinforces the qi-regulating and counterflow-descending potency, producing better improvement in qi counterflow symptoms such as hiccough.

3. Pronounced Spleen-Stomach Qi Deficiency

When spleen-stomach qi deficiency symptoms are prominent, the dosages of Dazao and Gancao may be increased and Dangshen (Codonopsis Root) or Huangqi (Astragalus Root) may be incorporated. Dazao and Gancao themselves have spleen-tonifying and qi-boosting actions; increasing their dosages reinforces the spleen-tonifying potency. Dangshen tonifies the middle and boosts qi; Huangqi tonifies qi and raises yang — with both added, the spleen and stomach's transforming and transporting function is further reinforced and the righteous qi is elevated. For example, Dazao may be increased from 6 pieces to 9 pieces, Gancao from 6 g to 9 g, and Dangshen or Huangqi 10–15 g may be added, to more effectively treat the condition of stomach deficiency with heat accompanied by pronounced spleen-stomach qi deficiency.

VIII. Dosage and Preparation

1. Traditional Method

2. Modern Concentrated Granules

Convenience of Administration

Modern concentrated granules are produced from traditional Chinese herbs through extraction, concentration, and related processes. Administration is more convenient — simply dissolve in hot water to take. For busy modern patients, this saves the time and effort of decocting herbs.

Dosage Differences from Traditional Decoction

The dosage of modern concentrated granules differs from that of the traditional decoction. Generally speaking, for Ju Pi Zhu Ru Tang concentrated granules, each herb's dosage is adjusted according to the content of its active constituents. For example, the dosage of Jupi concentrated granules may be equivalent to approximately one-third of the Jupi quantity used in the traditional decoction, with Zhuru, Shengjiang, Dazao, Gancao, and other herbs adjusted accordingly. The specific dosage should be taken according to the product instructions or the physician's guidance to ensure therapeutic effects similar to those of the traditional decoction.

IX. Precautions and Contraindications

1. Dietary Restrictions

During the course of taking Ju Pi Zhu Ru Tang, spicy, greasy, and irritating foods should be avoided. Such foods readily add burden to the gastrointestinal tract, impairing the transforming and transporting function of the spleen and stomach and hindering recovery. Foods such as chilli peppers, fried foods, strong tea, and coffee should be avoided as far as possible. At the same time, a light diet should be maintained with an emphasis on easily digestible foods such as rice porridge and noodles, which helps to nourish the spleen and stomach.

2. Special Populations

Pregnant women using Ju Pi Zhu Ru Tang must do so under strict medical supervision. Although Ju Pi Zhu Ru Tang may be used to treat morning sickness, the physiological condition of pregnant women is unique and medication requires particular caution; herb dosages and administration methods must be adjusted appropriately according to the specific condition of the pregnant woman, ensuring safe and effective use. In addition, those with spleen-stomach deficiency-cold should use this formula with caution. Spleen-stomach deficiency-cold manifests as cold pain in the epigastric region, preference for warmth and pressure, a bland tasteless mouth without thirst, and cold limbs with loose stools. As Ju Pi Zhu Ru Tang is inclined towards clearing heat and harmonising the stomach, it may worsen deficiency-cold symptoms in those with spleen-stomach deficiency-cold, which is unfavourable to the condition.

3. Drug Interactions

If currently taking other medications, a physician or pharmacist should be consulted before using Ju Pi Zhu Ru Tang, as drug interactions may exist. Certain medications may react with the constituents of Ju Pi Zhu Ru Tang, affecting drug efficacy or producing adverse reactions. For example, concurrent use with medicinals containing Lilu (Veratrum) may produce toxic reactions and should be avoided.

X. Modern Research

1. Pharmacological Research

Ju Pi Zhu Ru Tang governs the pulse patterns, diagnosis, and treatment of vomiting, hiccough, and diarrhoea, applicable for stomach-heat or deficiency-heat vomiting and hiccough among the vomiting, hiccough, and diarrhoea conditions. It is often compared with Jupi Tang in clinical application for stomach-heat vomiting and hiccough patterns.

Modern research has demonstrated that Ju Pi Zhu Ru Tang possesses multiple pharmacological actions. Among these, it has a regulatory effect on gastrointestinal function: Jupi, Shengjiang, and related herbs promote gastrointestinal peristalsis and enhance digestive function, helping to improve gastrointestinal discomfort symptoms such as epigastric fullness and distension, nausea, and vomiting. Zhuru has certain anti-inflammatory and antibacterial properties, capable of reducing gastric mucosal inflammatory responses and providing some reparative benefit for gastric mucosal damage caused by stomach deficiency with heat. In addition, Gancao has immune-regulatory actions, enhancing the body's resistance and facilitating recovery from illness.

2. Clinical Efficacy Verification

In clinical research, through observation of large numbers of patients treated with Ju Pi Zhu Ru Tang for hiccough, morning sickness, and related conditions, good clinical efficacy has been verified. Research has found that Ju Pi Zhu Ru Tang can significantly relieve hiccough symptoms, shorten the duration of hiccough, and improve patients' quality of life. For patients with morning sickness, it can effectively reduce nausea and vomiting, improve the nutritional status of pregnant women, and ensure normal fetal development. These clinical research findings further confirm the effectiveness and safety of Ju Pi Zhu Ru Tang in treating related conditions.

3. Dosage Form Improvement Research

With the development of modern science and technology, research into dosage form improvement for Ju Pi Zhu Ru Tang has been ongoing. In addition to the modern concentrated granules mentioned above, research is also underway to produce capsule and oral liquid forms. These new dosage forms, while maintaining the efficacy of the original formula, offer the advantages of convenient administration and easy storage, better meeting the needs of modern clinical application. For example, capsules allow precise control of drug dosage and are convenient for patients to carry and take; oral liquids are rapidly absorbed and have better palatability, suiting the needs of different patient groups. Dosage form improvement research provides more options for the clinical application of Ju Pi Zhu Ru Tang and helps better realise its therapeutic potential.
