Ginger and Nausea: What the Research Shows

Ginger for nausea is one of the oldest and most universal uses of this root, well beyond Ayurvedic tradition alone. It's also one of the areas where scientific research offers relatively solid data. Here is what it shows, and the key nuances worth knowing before expecting too much.

What the gastric-emptying study shows

A study by Wu, Rayner and colleagues, published in 2008 in European Journal of Gastroenterology & Hepatology, observed in healthy volunteers that taking ginger accelerated gastric emptying compared to placebo (see the study on Google Scholar). Faster gastric emptying is consistent with reduced nausea, since nausea is often linked to a stomach that empties too slowly. This biological mechanism offers a plausible explanation for ginger's traditional use against nausea.

What a broader digestion review confirms

A systematic review of clinical trials published in 2019 in Food Science & Nutrition by Nikkhah Bodagh and colleagues reports that ginger improves digestive symptoms such as nausea and bloating across several controlled trials, in addition to its effect on gastric emptying (see the study on Google Scholar). This synthesis reinforces the idea of a real effect for ginger across several types of nausea, without making it a universal remedy.

Which types of nausea are involved?

Type of nausea	What the data suggests
Mild digestive nausea, after a heavy meal or sluggish digestion	Traditional use consistent with the observed effect on gastric emptying
Motion sickness	Common traditional use, though the scientific data is less consistent than for digestion
Nausea during pregnancy (morning sickness)	Widespread traditional use, but medical or midwife advice is essential before regular use
Nausea linked to chemotherapy or a medical condition	Never a matter of self-medicating with ginger alone; medical follow-up is required

A plausible mechanism, not a guarantee for every situation

These studies were conducted in healthy volunteers or in specific contexts: they don't support extrapolating a guaranteed effect for every type of nausea, particularly when an underlying medical cause is at play. Our guide Ayurveda and science explains why a plausible, even well-documented, biological mechanism never replaces a diagnosis when nausea is frequent, severe or unexplained.

Using ginger for everyday digestion

As a general guide, fresh grated ginger at the start of a meal, or as a tea like our ginger-turmeric tea, is the most common traditional use. Our article on sluggish fall digestion details how to work it into a broader routine of digestive support, particularly during seasonal shifts in pace.

Precautions

Ginger in usual culinary amounts is generally well tolerated. It's worth moderating for people on anticoagulant treatment or with gallstones: ask for medical advice if in doubt or for concentrated, regular use. During pregnancy, ginger used in ordinary culinary amounts is generally well tolerated, but morning sickness is worth discussing with your doctor or midwife before regular, concentrated consumption. Frequent, severe, unexplained nausea, or nausea accompanied by other symptoms (abdominal pain, weight loss, fever) calls for medical advice, not simply using ginger. General guidelines are detailed in our safety and precautions guide.
