Ginger is a flowering plant that originated in Southeast Asia. It’s among the healthiest (and most delicious) spices on the planet.

It belongs to the Zingiberaceae family, and it’s closely related to turmeric, cardamom, and galangal.

The rhizome (underground part of the stem) is the part commonly used as a spice. It’s often called ginger root or, simply, ginger.

Ginger can be used fresh, dried, powdered, or as an oil or juice. It’s a very common ingredient in recipes. It’s sometimes added to processed foods and cosmetics.

Here are some health benefits of ginger that are supported by scientific research.

Contains gingerol, which has powerful medicinal properties

Ginger has a very long history of use in various forms of traditional and alternative medicine. It’s been used to aid digestion, reduce nausea, and help fight the flu and common cold, to name a few of its purposes.

The unique fragrance and flavor of ginger come from its natural oils, the most important of which is gingerol.

Gingerol is the main bioactive compound in ginger. It’s responsible for much of ginger’s medicinal properties.

Gingerol has powerful anti-inflammatory and antioxidant effects, according to research. For instance, it may help reduce oxidative stress, which is the result of having an excess amount of free radicals in the body

Can treat many forms of nausea, especially morning sickness

Ginger appears to be highly effective against nausea .

It may help relieve nausea and vomiting for people undergoing certain types of surgery. Ginger may also help chemotherapy-related nausea, but larger human studies are needed

However, it may be the most effective when it comes to pregnancy-related nausea, such as morning sickness.

According to a review of 12 studies that included a total of 1,278 pregnant women, 1.1–1.5 grams of ginger can significantly reduce symptoms of nausea.

However, this review concluded that ginger had no effect on vomiting episodes

Although ginger is considered safe, talk with your doctor before taking large amounts if you’re pregnant.

It’s recommended that pregnant women who are close to labor or who’ve had miscarriages avoid ginger. Ginger is contraindicated with a history of vaginal bleeding and clotting disorders as well .

Ginger may play a role in weight loss, according to studies conducted in humans and animals.

A 2019 literature review concluded that ginger supplementation significantly reduced body weight, the waist-hip ratio, and the hip ratio in people with overweight or obesity

A 2016 study of 80 women with obesity found that ginger could also help reduce body mass index (BMI) and blood insulin levels. High blood insulin levels are associated with obesity.

Study participants received relatively high daily doses — 2 grams — of ginger powder for 12 weeks .

A 2019 literature review of functional foods also concluded that ginger had a very positive effect on obesity and weight loss. However, additional studies are needed

The evidence in favor of ginger’s role in helping prevent obesity is stronger in animal studies.

Rats and mice who consumed ginger water or ginger extract consistently saw decreases in their body weight, even in instances where they’d also been fed high fat diets

Ginger’s ability to influence weight loss may be related to certain mechanisms, such as its potential to help increase the number of calories burned or reduce inflammation

May drastically lower blood sugars and improve heart disease risk factors

This area of research is relatively new, but ginger may have powerful anti-diabetic properties.

In a 2015 study of 41 participants with type 2 diabetes, 2 grams of ginger powder per day lowered fasting blood sugar by 12% .

It also dramatically improved hemoglobin A1c (HbA1c), a marker for long-term blood sugar levels. HbA1c was reduced by 10% over a period of 12 weeks.

There was also a 28% reduction in the Apolipoprotein B/Apolipoprotein A-I ratio and a 23% reduction in malondialdehyde (MDA), which is a byproduct of oxidative stress. A high ApoB/ApoA-I ratio and high MDA levels are both major risk factors of heart disease.

However, keep in mind that this was just one small study. The results are incredibly impressive, but they need to be confirmed in larger studies before any recommendations can be made.

In somewhat encouraging news, a 2019 literature review also concluded that ginger significantly reduced HbA1c in people with type 2 diabetes. However, it also found that ginger had no effect on fasting blood sugar.

Can help with osteoarthritis

Osteoarthritis (OA) is a common health problem.

It involves degeneration of the joints in the body, leading to symptoms such as joint pain and stiffness.

One literature review found that people who used ginger to treat their OA saw significant reductions in pain and disability

Only mild side effects, such as a dissatisfaction with the taste of ginger, were observed. However, the taste of ginger, along with stomach upset, still prompted nearly 22% of the study participants to drop out.

Study participants received between 500 milligrams (mg) and 1 gram of ginger each day for anywhere from 3 to 12 weeks. A majority of them had been diagnosed with OA of the knee

Another study from 2011 found that a combination of topical ginger, mastic, cinnamon, and sesame oil can help reduce pain and stiffness in people with OA of the knee

Can help treat chronic indigestion

Chronic indigestion is characterized by recurrent pain and discomfort in the upper part of the stomach.

It’s believed that delayed emptying of the stomach is a major driver of indigestion. Interestingly, ginger has been shown to speed up emptying of the stomach.

People with functional dyspepsia, which is indigestion with no known cause, were given either ginger capsules or a placebo in a small 2011 study. One hour later, they were all given soup.

It took 12.3 minutes for the stomach to empty in people who received ginger. It took 16.1 minutes in those who received the placebo

These effects have also been seen in people without indigestion. In a 2008 study by some members of the same research team, 24 healthy individuals were given ginger capsules or a placebo. They were all given soup an hour later.

Consuming ginger as opposed to a placebo significantly accelerated emptying of the stomach. It took 13.1 minutes for people who received ginger and 26.7 minutes for people who received the placebo

May significantly reduce menstrual pain

Dysmenorrhea refers to pain felt during the menstrual cycle.

One of the traditional uses of ginger is for pain relief, including menstrual pain.

In a 2009 study, 150 women were instructed to take either ginger or a nonsteroidal anti-inflammatory drug (NSAID) for the first 3 days of their menstrual period.

The three groups received four daily doses of either ginger powder (250 mg), mefenamic acid (250 mg), or ibuprofen (400 mg). Ginger managed to reduce pain as effectively as the two NSAIDs.

More recent studies have also concluded that ginger is more effective than a placebo and equally as effective as drugs such as mefenamic acid and acetaminophen/caffeine/ibuprofen (Novafen)

While these findings are promising, higher quality studies with larger numbers of study participants are still needed.

Gingerol can help lower the risk of infections.

In fact, ginger extract can inhibit the growth of many different types of bacteria

According to a 2008 study, it’s very effective against the oral bacteria linked to gingivitis and periodontitis. These are both inflammatory gum diseases 

Fresh ginger may also be effective against the respiratory syncytial virus (RSV), a common cause of respiratory infections.

Ginger is loaded with nutrients and bioactive compounds that have powerful benefits for your body and brain. Consider adding ginger to your diet.
