Ginger root, the edible portion used for culinary and health purposes, is actually a stem that is found in the soil, called a rhizome.
This herb is known for its pungent yet pleasant smell, which stems from two of its chief compounds, namely, gingerol and shogaol.
Besides its widespread culinary use, ginger is also credited with considerable therapeutic potential for relieving a wide array of health complaints, such as nausea, coughing, chest congestion, and gastrointestinal distress.
This article will discuss the many uses of ginger, its health benefits, and some recipes that use this popular herb.
Nutritional Value of Ginger
Ginger is a good source of vitamins A, B, C, and E, as well as minerals including calcium, iron, magnesium, phosphorus, potassium, sodium, and zinc.
Only 80 calories are found in 100 grams of fresh ginger, along with 2 grams of protein, 1 gram of fat, and 2 grams of fiber. (1)
This herb is known to exhibit significant anti-inflammatory, antibacterial, antiseptic, antifungal, and antiviral properties.
Health Benefits of Ginger
Ginger has been used as a medicinal herb for centuries and continues to be an important home remedy.
1. May help with gastrointestinal distress
Ginger works as a digestive aid that can help in breaking down a heavy meal and the faster emptying of the stomach. By relaxing the gastrointestinal muscles, ginger can help relieve abdominal gas and cramping. (2)(3)
2. Relieves cough and cold
The phenolic compounds that make ginger so aromatic – the gingerols, paradols, and shogaols – are powerful antioxidants as well as anti-inflammatory and antimicrobial agents.
All these properties can help fight viral infections such as the common cold and can also help relieve their discomforting symptoms.
Ginger is also known to relieve nausea and vomiting. (6) Moreover, ginger functions as a natural analgesic and can reduce the pain or irritation caused by a sore throat, coughing, postnasal drip, and mucus in the lungs.
3. Alleviates morning sickness
Ginger is found to be effective in treating nausea during pregnancy, but more studies are needed to determine the exact efficacy of this herb and appropriate dosage. (8)
Caution: While no studies have found any evidence that ginger consumption increases the risk of harm during pregnancy, it is unknown if and how much ginger is safe for pregnant women. Always consult your doctor before starting any over-the-counter medication, supplement, herbal medication, or tea.
4. Reduces arthritic pain
Some studies have shown that ginger extracts that contain gingerol and nongingerol components can prevent joint inflammation and degeneration. (9)
It was also found that ginger essential oils that contain both gingerol and nongingerol compounds are more effective in treating inflammation from rheumatoid arthritis. (9)
Another study found that the powerful compounds in ginger may help with the discovery and development of new drugs and therapies that relieve symptoms of rheumatoid arthritis and the bone destruction caused by the disease. (11)
- To treat pain, make a paste of fresh ginger and turmeric. Warm the paste and apply it to the affected area twice a day.
- Consume raw and cooked ginger as a regular part of your diet.
- Add ginger essential oil to your bathwater to help relieve joint and muscle pain.
5. Relieves menstrual symptoms
Ginger may also help reduce the volume of menstrual flow, especially during the first 3–7 days. (14)
You can take this herb in the form of tea or capsules, but only in recommended amounts.
6. Eases migraines
There is evidence to support that ginger may help relieve migraines and other discomforts associated with it, both in children and adults. (16)
Ginger can also provide some relief to dizziness and nausea often suffered as a side effect of the migraine. The medicinal intake of ginger may not only reduce the severity but also the frequency of migraine attacks.
7. Promotes heart health
Ginger does help in maintaining cholesterol levels. However, for a healthy heart, you cannot ignore the importance of a healthy lifestyle and diet.
8. Provides respiratory relief
Ginger contains multiple compounds that may help suppress allergic reactions, fight inflammation of the airways, improve asthmatic reactions, and fight respiratory viruses. This is largely due to its anti-inflammatory and antimicrobial properties.
Ginger helps curb the inflammatory response in the respiratory airways triggered by an allergy, infection, or asthma to restore normal breathing.
One study found evidence that fresh ginger can help fight the plaques in the airway that are caused by human respiratory syncytial virus (HRSV), a leading cause of respiratory infections, but found dried ginger to be ineffective. (20)
Other Health Benefits
As more research is done on this herb, more potential benefits are being discovered. Here are a few interesting ways that ginger may help your health:
- Lightens skin: Gingerol is a powerful compound found in ginger that may help counter reactive oxygen species and reduce the production of melanin (melanogenesis), which causes pigmentation in the skin. (21)
- Elevates testosterone: Ginger supplementation may increase testosterone production in males, but more research is needed to confirm this claim. (22)
- Improves brain function: The antioxidants and other powerful compounds in ginger may stop inflammation in the brain. Inflammation can accelerate age-related cognitive decline and pave the way for Alzheimer’s disease and other such mental disorders. (23) Additionally, ginger extract was found to improve the working memory and reaction time in middle-aged women. (24)
- May help with drug withdrawal: One animal study found that ginger extract may help lessen morphine-induced addictive behaviors. (25)
How Ginger Is Used
Ginger has many different uses and applications. Because ginger has a peppery, warm, and slightly sweet taste as well as a strong aroma, it has been popular for many centuries and used in various ways.
Some of the popular and widely used forms of ginger include candied ginger, crystallized ginger, dried ginger, fresh ginger, pickled ginger, and ground ginger.
Ginger can be eaten raw or cooked safely, although many people prefer the cooked form, as raw ginger can have a strong, spicy taste.
Fresh ginger is often used to make ginger tea, ginger ale, and other beverages. The dried, ground, powdered, and preserved forms of ginger are traded internationally.
Ground ginger as a cooking ingredient is used around the world. It is also used in food processing as a flavoring agent.
Ginger can also be found often in baked goods and desserts. Preserved ginger is also often used in baked goods, candies, jams, and marmalades.
How to Store Ginger
Ginger is a staple in many kitchens around the world. If stored properly, it can last for quite some time. Fresh ginger can be kept for up to 3 weeks in the refrigerator if unpeeled.
Keep ginger powder in a tightly sealed glass container. Store this bottle in a cool, dry, and dark place, such as a pantry. It can also be stored in the refrigerator for about 1 year.
Many people take ginger supplements that come in capsule form for a variety of health reasons, but it is necessary that you consult a doctor before starting.
Like any other supplement, ginger supplements are safe only when taken in the appropriate dosage.
The essential oil from ginger has the characteristic flavor and aroma of the herb but is not as pungent. It is often used to flavor beverages and as an ingredient in candy, cosmetics, perfumes, and pharmaceutical applications.
Ginger extract is just as pungent as fresh ginger and works as a substitute for ground ginger. It is mainly used to flavor drinks and manufacture pharmaceuticals.
Adverse Effects of Ginger
Although ginger is generally recognized as safe and is widely used in cooking and baking, certain people should exercise caution when taking ginger supplements or consuming a lot of ginger.
Here are a few important considerations to avoid any unforeseen reaction to the medicinal use of ginger:
- Adverse side effects of ginger are rare but can include irritation in and around the mouth, heartburn, and diarrhea. Those who drink ginger tea may want to limit their intake to 1–2 cups per day as it may cause heartburn and upset stomach.
- People who suffer from gallstones may also want to be careful when consuming ginger, as it is believed that ginger can increase the flow of bile. (26)
- Ginger can thin the blood. Therefore, it should be stopped 2 weeks before any surgery and should not be used after surgery.
- Some patients like to take ginger supplements after surgery to help control the associated nausea and vomiting, but this can increase the risk of bleeding and should be avoided.
- Due to its anticoagulant effect, medicinal intake of ginger is not advisable for people with bleeding disorders or those who are already taking blood thinners.
- Pregnant or lactating women should also avoid taking this herb in more than food amounts.
