Does Ginger Help Indigestion?The Preparation and Outcome Matter

“Helps digestion” can refer to a stomach-emptying measurement, less nausea or a lower symptom score after several weeks. Ginger studies have measured all of these, using preparations that differ considerably. A favorable result needs its food or capsule, comparison and outcome attached.¹²³⁴

Indigestion can involve discomfort or burning in the upper abdomen, feeling full too soon, uncomfortable fullness after eating, bloating or nausea. Heartburn can occur alongside it, but the two are separate conditions. The trials below concern functional dyspepsia, rather than every cause of post-meal discomfort.⁵

Ginger powder moved soup faster without improving symptoms

Published in 2011, a randomized crossover experiment tested 11 patients with functional dyspepsia on two afternoons. They took three capsules containing a total of 1.2 grams of ginger-root powder or starch placebo, then drank 500 milliliters of low-calorie soup an hour later. Researchers estimated stomach emptying through ultrasound.¹

The median estimated half-emptying time was 12.3 minutes with ginger and 16.1 minutes with placebo. Yet the reported gastrointestinal sensations did not differ between study days. The patients had not been selected for delayed stomach emptying.¹

The short observation, limited to 90 minutes for the reported emptying assessment, and the light liquid meal leave questions about repeated treatment and ordinary meals. This experiment showed a physiological change; it did not demonstrate symptom relief or test treatment for diagnosed gastroparesis.¹

The ginger-and-artichoke trial tested both ingredients together

The four-week randomized trial published in 2015 included 126 adults, assigned to the combination or placebo. Each active capsule contained 100 milligrams of standardized artichoke extract and 20 milligrams of standardized ginger extract. Participants took one before lunch and one before dinner.²

At four weeks, 41 of 65 combination recipients reported marked or complete improvement, compared with 15 of 61 placebo recipients. This was the participants’ overall rating. Indena supplied the products, and three authors had affiliations with its research and development unit.²

The combination had no ginger-only arm. Its result cannot identify which ingredient contributed, whether both were necessary or whether adding ordinary ginger to food would reproduce the benefit.

A before-and-after study supplies a weaker comparison

A study published in 2023 followed 51 patients who completed four weeks of ginger supplementation, including 40 women. They took two 540-milligram capsules daily. Several symptom measures improved from baseline, but the heartburn change was not statistically significant.³

Everyone received ginger. Without a placebo or untreated comparison, the study cannot establish how much improvement came from the supplement, expectations or the fluctuation of symptoms. Its observations help frame another trial; they should not be described as a placebo-controlled treatment effect.

A steamed extract improved scores over 12 weeks

The trial published in 2025 randomized 80 adults with mild to moderate functional dyspepsia at two Bangalore hospitals. There were 52 men and 28 women. Participants received 480 milligrams daily of steamed ginger extract GGE03 or placebo for 12 weeks.⁴

Average total Gastrointestinal Symptom Rating Scale scores fell by 15.8 points with the extract and 1.8 with placebo, a significant between-group difference. The scale collects patients’ symptom reports.⁴

This provides controlled evidence of symptom benefit for that extract. It did not compare GGE03 with tea or powder, or establish lasting benefit after stopping. Authors included staff from SD Biotechnologies, Daewon Pharmaceutical and 3H-LABS; the paper declared no conflicts of interest. Six extract recipients and nine placebo recipients reported adverse events, which investigators judged unrelated to treatment. That does not guarantee safety for every user.⁴

Match a product claim to the product tested

Before buying a capsule advertised with one of these studies, check the preparation. Was it powder, a standardized extract or a steamed extract? Was artichoke also present? Does the label describe the same ingredient, or merely use the word “ginger”?

Then check the promised outcome. A shorter estimated emptying time does not tell you whether fullness or pain improved. Improvement from baseline does not tell you whether the product outperformed placebo. Those are practical questions to bring to a pharmacist or clinician with the label and cited paper.

The NCCIH⁶ notes that oral ginger can itself cause abdominal discomfort, heartburn, diarrhea, and mouth or throat irritation. It advises discussing ginger or other herbal products with a health care provider when taking medicines. Its findings on pregnancy-related nausea should not be repurposed as proof of benefit for chronic indigestion.⁶

Persistent indigestion needs an explanation

Treatment depends on its cause. NIDDK⁷ describes options such as acid-lowering medicines, treatment of H. pylori infection and other medicines or therapies chosen for the person’s symptoms. Its advice includes a supplement discussion with a doctor before use. Ginger studies do not replace that assessment.⁷

See a doctor if indigestion does not improve. Difficulty or pain with swallowing, frequent vomiting, bloody vomit, black tar-like stools, severe constant abdominal pain or unintended weight loss require prompt medical attention, according to NIDDK⁵.⁵

If a gastric-emptying test has been ordered, our guide to the test explains how to ask about its purpose and preparation. A supplement trial’s ultrasound measurement is not your diagnostic test result.

Bloated by Dinner, Chapter 11’s “Week 1: Start the Clock,” describes logging meal times, symptoms, medicines and supplements. Use those entries to show when discomfort begins and how it affects eating. The log can inform an appointment; it cannot determine whether your stomach empties slowly or whether ginger treats the cause.
