5 Chinese Herbs for Slow Gastric Emptying

Herbs for slow gastric emptying can offer a natural and holistic option for managing symptoms of slow gastric emptying, a condition in which the stomach empties food into the small intestine more slowly than normal, often causing nausea, bloating, and early satiety. This condition is commonly seen in individuals with diabetes and other chronic health issues, and conventional treatments may be limited by side effects or inconsistent results. 

Traditional Chinese Medicine (TCM) provides alternative strategies, including the use of herbal remedies to support digestive health and improve gastric motility. In this blog, we’ll introduce five Chinese herbs and formulas that are backed by scientific research for their potential to aid those struggling with slow gastric emptying.

1. Xiangsha Liujunzi Decoction (XSLJZD)

One classical TCM formula that has shown promise for managing slow gastric emptying is Xiang Sha Liu Jun Zi Decoction (XSLJZD). This herbal blend combines key ingredients such as Codonopsis pilosula (Dang Shen), Atractylodes macrocephala (Bai Zhu), and Citrus reticulata (Chen Pi), among others, and is traditionally used to strengthen the spleen and regulate qi. 

Modern research supports its traditional use. A systematic review of 10 randomized controlled trials involving 867 patients found:

• XSLJZD significantly improved gastric emptying
• It reduced common symptoms such as nausea, bloating, and early satiety
• It performed better than standard prokinetic drugs in managing diabetic gastroparesis

These findings highlight XSLJZD as a compelling herbal alternative or complement to conventional therapies, especially for individuals seeking a more holistic approach to digestive health.

2. Zhiqiao-Houpu Herb Pair (Fructus Aurantii & Magnolia officinalis)

Another notable herb pair is the combination of Fructus Aurantii (Zhiqiao) and Magnolia officinalis (Houpu), which has long been used to regulate qi and relieve digestive stagnation. This duo is often included in formulas aimed at easing abdominal fullness, bloating, and sluggish digestion—key symptoms associated with functional gastrointestinal disorders.

Modern pharmacological studies have revealed that the Zhiqiao-Houpu herb pair can modulate gastric motility in a dose-dependent, bidirectional manner, meaning:

• Low doses tend to stimulate gastric emptying, aiding those with delayed digestion.
• High doses may inhibit gastric emptying, which can be beneficial in cases of hypermotility or rapid transit.

Animal studies have supported this dual regulatory effect, suggesting the Zhiqiao-Houpu combination holds potential as a targeted therapeutic option for functional dyspepsia and other motility-related issues. This ability to adapt based on dosage adds to the versatility and value of this herb pair in managing complex digestive conditions.

3. Zhizhu Pills (Aurantii Fructus Immaturus & Atractylodis Macrocephalae Rhizoma)

Zhizhu Pills are a traditional Chinese herbal formula commonly used to enhance digestive function and relieve symptoms such as bloating and abdominal distension. This formula typically includes herbs like Fructus Aurantii (Zhi Shi) and Atractylodes macrocephala (Bai Zhu), which work synergistically to promote the movement of qi and improve digestive efficiency.

Modern research has shown that Zhizhu Pills can improve gastrointestinal motility by modulating key digestive hormones and receptors, including:

• Upregulating the GHSR protein (growth hormone secretagogue receptor), which enhances the body’s responsiveness to ghrelin
• Increasing levels of ghrelin and serotonin (5-HT), both of which stimulate gastric motility and appetite
• Reducing calcitonin gene-related peptide (CGRP), which is associated with delayed gastric emptying and gastrointestinal discomfort

These effects contribute to improved gastric emptying and a reduction in functional dyspepsia symptoms, making Zhizhu Pills a scientifically supported option for individuals dealing with slow or irregular digestion.

4. Xiao-Banxia-Tang (Pinellia ternata Decoction)

Xiao-Banxia-Tang is a traditional Chinese herbal formula featuring Pinellia ternata (Banxia), a key herb used to treat nausea, vomiting, and digestive upset. Often prescribed for conditions involving stomach qi rebellion, this formula is valued for its calming effects on the digestive tract.

In modern studies, Xiao-Banxia-Tang has demonstrated antiemetic properties and the ability to influence gastrointestinal hormones, including:

• Modulating motilin levels, a hormone that plays a critical role in regulating gastric motility
• Reducing nausea and vomiting, particularly in cases of chemotherapy-induced gastrointestinal distress

Animal research further supports its potential in managing gastric motility disorders, suggesting that Xiao-Banxia-Tang could be a useful option for individuals experiencing functional dyspepsia or gastroparesis-related symptoms.

5. Ginger (Zingiber officinale)

Ginger (Zingiber officinale) is widely used for its warming properties and ability to support digestion. Often included in formulas to treat cold-related digestive issues, ginger helps promote the flow of qi and dispel stagnation in the stomach.

Modern research supports ginger’s traditional use, showing that it can:

• Stimulate gastric emptying, making it beneficial for those with delayed digestion or gastroparesis
• Reduce gastrointestinal discomfort, including symptoms like nausea and bloating
• Provide anti-inflammatory, antioxidant, antitumor, and antiulcer effects

Clinical trials have found that a divided daily dose of 1500 mg of ginger can effectively relieve nausea, which highlights its potential role in managing slow gastric emptying and related digestive disorders. 

Conclusion

These five herbs and formulas—XSLJZD, the Zhiqiao-Houpu herb pair, Zhizhu Pills, Xiao-Banxia-Tang, and Ginger—have shown promising results in improving gastric emptying and relieving common symptoms of gastroparesis, such as nausea, bloating, and early satiety. Each offers unique mechanisms, from hormone modulation to anti-inflammatory and prokinetic effects, making them valuable options for supporting digestive health.

For many individuals, combining TCM with conventional treatments may offer enhanced therapeutic benefits, addressing symptoms more holistically while potentially reducing side effects. However, it’s essential to consult with a qualified healthcare practitioner or licensed TCM provider before starting any herbal regimen, especially if you are currently taking medications or managing a chronic condition.

Slow Gastric Emptying FAQs

Q: What is slow gastric emptying (gastroparesis)?
A: Slow gastric emptying, or gastroparesis, is a digestive disorder where the stomach takes longer than normal to empty its contents into the small intestine. This can lead to symptoms like nausea, bloating, early fullness during meals, and abdominal discomfort.

Q: What causes gastroparesis?
A: Gastroparesis can be caused by a variety of factors, including diabetes (especially long-term or poorly managed), nerve damage (particularly to the vagus nerve), certain medications, post-surgical complications, and autoimmune conditions. In some cases, the cause remains unknown (idiopathic gastroparesis).

Q: How does TCM view slow gastric emptying?
A: In TCM, slow gastric emptying is often related to spleen qi deficiency, stomach qi stagnation, or dampness accumulation. These imbalances disrupt the normal flow of qi and digestion, leading to symptoms like bloating, nausea, and early satiety. Treatment focuses on tonifying the spleen, regulating qi, and resolving dampness to restore digestive function.

Q: Can TCM herbs really help with gastroparesis?
A: Yes, several classic TCM formulas and herbs—such as XSLJZD, Zhizhu Pills, and ginger—have been traditionally used for digestive complaints and are now supported by modern research showing improvements in gastric motility and symptom relief. However, it’s important to work with a qualified TCM practitioner to create a personalized treatment plan based on your unique pattern of imbalance.

Q: Can acupuncture help with slow gastric emptying?
A: Yes, acupuncture is often used in TCM to stimulate the digestive system and regulate the flow of qi and blood. Points like ST36 (Zusanli) and CV12 (Zhongwan) are commonly used to support spleen and stomach function, reduce nausea, and enhance gastric motility. Some clinical studies have also shown positive effects of acupuncture in managing gastroparesis symptoms.

Q: What kind of dietary changes does TCM recommend for gastroparesis?
A: TCM typically recommends a warm, soft, and easy-to-digest diet that supports spleen and stomach health. This may include congee, lightly cooked vegetables, and warm broths, while avoiding cold, raw, greasy, or overly sweet foods that can weaken the digestive system. Eating smaller, more frequent meals and chewing thoroughly can also support smoother digestion.
