Ginger for nausea - Does it really work?

Ginger for nausea - Does it really help?

23 Nov 2022 • 2 min read

Does ginger really help feelings of sickness and nausea? The quick answer is yes, research has shown that ginger can increase the responsiveness of the digestive system and speed stomach emptying, which leads to reduced feelings of nausea.1 The spicy herb also has anti-inflammatory properties that also improve digestion, but also supports blood-pressure-regulating hormones that calms the body and also reduces nausea.2

How does ginger relieve feelings of nausea?

So, we already know that ginger has a positive effect on the digestive system and blood pressure, which leads to reduced feelings of nausea, but what's the science behind it all? Ginger gets most of its health benefits  from the main bioactive component gingerol and related compounds called shogaols. Shogaols is what gives ginger its pungent taste. Gingerols and shogaols work by blocking the actions of the neurotransmitters acetylcholine and serotonin in the body. Acetylcholine triggers involuntary stomach contractions, while serotonin can stimulate the vomiting reflex. By preventing these chemicals from working, this is how ginger may help with nausea.3

Is fresh or dried ginger better?

Shogaols are more concentrated in dried ginger, whereas gingerols are more concentrated in raw ginger. The active components in ginger are called gingerols. When ginger is dried or cooked, gingerols form substances called shogaols. Gingerols and shogaols have similar antimicrobial and antioxidant effects, but shogaols are twice as potent. This means that supplements made from dried ginger may be more biologically active than fresh ginger.4

Different types of nausea

Below are the common types of nausea and how ginger can help:

1. Ginger for motion sickness

Several studies suggest that ginger may help with motion sickness. In a double-blind randomized placebo trial carried out in 1988, 80 Danish naval cadets were given 1g of either ginger or a placebo before undertaking a sea voyage. Ginger reduced vomiting and cold sweats significantly better than the placebo over a four-hour period.5 In a 2003 joint study by Taiwan’s National Yang-Ming University and the University of Michigan, researchers gave 13 volunteers with a history of motion sickness a 1g or 2g dose of ginger before seating them in a rotating drum. They found that pre-treatment with ginger effectively reduced nausea.6

2. Ginger for pregnancy sickness

Ginger may support women who experience pregnancy sickness. A 2016 review reported that ginger may stop vomiting for one in three women, or improve nausea and vomiting during the first trimester.7 However, it is unlikely to help with the symptoms of the more serious hyperemesis gravidarum, which causes persistent vomiting resulting in weight loss, dehydration and electrolyte imbalance; it is a leading cause of hospital admissions during early pregnancy. Despite some trials historically suggesting ginger is better than placebo for hyperemesis gravidarum (HG), these trials had various flaws and more recent research has shown that for around 50% of women with HG ginger actually made symptoms worse, increased acid reflux and caused pain on vomiting. Most striking, was that woman with HG reported that people suggesting ginger as a remedy had a negative emotional effect on them. HG is a serious and potentially life-threatening medical condition and suggesting ginger as a treatment was reported to de-validate or belittle their experience and undermine the seriousness of their illness. Check with your GP before taking ginger supplements, as they may not be suitable for everyone. There is some evidence that ginger taken as a supplement may affect the way blood clots so patients who have conditions such as thrombocytopenia, are on some cancer treatments or who are at increased risk of bleeding, should avoid high doses of ginger.

3. Ginger for nausea caused by medication

For many people, nausea and vomiting are unwanted yet unavoidable side effects of certain medicines and medical treatments, such as chemotherapy. Could ginger help? In a study of 576 patients receiving chemotherapy, researchers at New York’s University of Rochester Medical Center found that taking 0.5-1g ginger every day for six days, beginning three days before the first session, significantly helped to reduce nausea.8

Side effects of taking ginger

Negative side effects such as heartburn, indigestion, diarrhoea and a burning or painful mouth are usually due to ingesting too much ginger.9 Side effects depend on many factors such as the individual, dosage, frequency and how the ginger is ingested. If you are pregnant, breast-feeding or taking any medication, talk to your GP before upping your intake of ginger, either fresh or as supplements.

How much ginger should I take for nausea?

The Food and Drug Administration recommends consuming no more than 4 grams of ginger per day is safe.70 Currently there isn’t a unanimity around the most effective amount of ginger for easing feelings of sickness and nausea. Studies tend to use between 200 and 2,000mg.11 Saying this, taking the condition out of the equation, most research has found that dividing between 1,000 and 1,500mg of ginger into smaller doses is the best way to treat nausea. Higher does have been found to be less effective and can cause more negative side effects.12 If you are taking a ginger supplement, there will be a recommended dosage on the back of the packaging. Never exceed recommendations and always talk to your GP before taking supplements, especially if you have existing medical conditions, take medication, are pregnant or breastfeeding.
