Functional dyspepsia — the medical term for recurring indigestion without an identifiable structural cause — is among the most common digestive complaints worldwide. A 2021 meta-analysis of randomized controlled trials published in BMC Complementary Medicine and Therapies (PMID: 33407405) found that therapies based on Si Jun Zi Tang (Four Gentlemen Decoction), a foundational digestive formula made from four food-grade herbs, were associated with improved symptom response and reduced relapse compared with placebo or conventional treatment across 12 trials involving 1,241 participants.
A separate 2021 network meta-analysis in Chinese Medicine (PMID: 34930390), which pooled 47 randomized controlled trials, found that several Chinese herbal formulas demonstrated overall efficacy comparable to or exceeding prokinetic drugs for functional dyspepsia, with certain formulas suggested as options for people who do not respond to prokinetics.
These findings are preliminary and the underlying studies vary in quality; they describe patterns of evidence rather than a recommendation. TCM approaches remain individualized and are best used alongside, not in place of, conventional care.
The ingredients discussed on this page — including hawthorn, malt, radish seed, and Chinese yam — are widely used as food ingredients and are generally recognized as safe in dietary amounts. However, herbal formulas are concentrated and can interact with medications; for example, hawthorn may interact with certain heart and blood-pressure medications. If you are pregnant, breastfeeding, taking prescription medication, or have a diagnosed digestive condition, consult a qualified healthcare provider before making significant changes to your diet or taking any herbal formula.

In TCM, this concern is differentiated into several patterns, each with a classical herbal formula. Patterns are identified by a practitioner through the overall symptom picture, and formulas are selected to match the individual pattern:
Fullness and distension after overeating, sour belching, aversion to food, and a thick greasy tongue coating. Addressed by harmonizing the stomach and removing food stagnation.
Formula: Baohe Wan (Harmony-Preserving Pill) — from Teachings of Master Danxi
Poor appetite with bloating that worsens after eating, loose stools, and fatigue. Addressed by strengthening the spleen and moving qi.
Formula: Xiang Sha Liu Jun Zi Tang (Aucklandia and Amomum Six-Gentleman Decoction) — from Discussion of Famous Physicians' Formulas Past and Present
Weak digestion with poor appetite, fatigue, and a pale complexion. Addressed by tonifying qi and strengthening the spleen and stomach.
Formula: Liujunzi Tang (Six-Gentleman Decoction) — from Yi Xue Zheng Chuan
Epigastric distension and discomfort triggered or worsened by stress or emotional upset, often with belching. Addressed by soothing the liver and harmonizing the stomach.
Formula: Chaihu Shugan San (Bupleurum Liver-Coursing Powder) — from Jingyue's Complete Works
Dull epigastric discomfort relieved by warmth and pressure, with a preference for warm drinks. Addressed by warming the middle and dispelling cold.
Formula: Li Zhong Wan (Center-Regulating Pill) — from Treatise on Cold Damage
A mix of symptoms such as upper abdominal fullness with rumbling, nausea, or loose stools. Addressed by harmonizing cold and heat and regulating the middle burner.
Formula: Banxia Xiexin Tang (Pinellia Heart-Draining Decoction) — from Treatise on Cold Damage
These formulas are for reference under TCM syndrome differentiation and should only be used under the guidance of a qualified practitioner.
Food therapy is the gentler, everyday counterpart to herbal formulas. Simple congees and teas made from food-grade ingredients are traditionally used to support comfortable digestion — most of the recipes below emphasize hawthorn and Chinese yam, which are classically associated with aiding digestion and gently strengthening the spleen and stomach.
In traditional Chinese medicine, indigestion is understood as arising from irregular eating with food stagnating in the stomach, emotional disturbance causing liver qi to attack the stomach, or a weak spleen and stomach failing to transform and transport, so that the qi mechanism of the middle burner is impaired and its ascending-descending function is disordered.
In Traditional Chinese Medicine, indigestion is understood as food stagnation in the stomach, a weakness of the spleen and stomach, or liver qi affecting the stomach. It is traditionally described as an impairment of the middle burner — the digestive center where food is transformed and transported. Different patterns are addressed with different approaches, from formulas that move food stagnation to those that strengthen the spleen and stomach.
Hawthorn (shan zha), Chinese yam (shan yao), malt (mai ya), radish seed (lai fu zi), and tangerine peel (chen pi) are traditionally used in soups, teas, and congees to support comfortable digestion. Simple congees combining these ingredients with rice are a staple of TCM food therapy for occasional indigestion.
Herbal formulas have been studied for functional dyspepsia, and some meta-analyses suggest they may support symptom relief. However, herbs can interact with medications and are not appropriate for everyone. Anyone considering an herbal formula should consult a qualified practitioner and their healthcare provider, especially if pregnant, breastfeeding, or taking medication.
Occasional indigestion after a heavy meal is common, but persistent or worsening symptoms — especially unexplained weight loss, difficulty swallowing, persistent vomiting, black or bloody stools, or pain that spreads to the arm or jaw — warrant prompt medical evaluation.
