What is Ginger?

The part of the ginger plant that we use is called the rhizome, which is also known as ginger root. You can use ginger in different forms, such as fresh, dried, powdered, or as oil or juice. It’s common in many recipes, home remedies, and beauty products.

Ginger can help with nausea, vomiting, and indigestion. Its unique smell and taste come from oils, particularly gingerol, which is responsible for many of ginger’s health benefits.

Ginger Uses, Dosage and Medicinal Properties

Most research on ginger benefits and side effects has focused on dosages ranging from 250 milligrams (mg) to 1 gram, taken one to four times daily. The Food and Drug Administration (FDA) considers ginger root generally safe and recommends a daily intake of up to 4 grams.

Ginger is rich in antioxidants but doesn’t provide many vitamins, minerals, or calories. According to the Department of Agriculture, 2 teaspoons of ginger contain just 4 calories and no significant amount of any nutrient.

Benefits of Ginger for Women and Men

1. Can Treat Morning Sickness and Other Nausea

Ginger might help with nausea, including morning sickness during pregnancy. It may also relieve nausea and vomiting for people having certain surgeries or undergoing chemotherapy according to a 2020 study. 

While several studies on ginger benefits and side effects suggest that ginger is generally safe, it’s a good idea to consult a doctor before taking large amounts if you’re pregnant. Ginger may not be suitable for those close to labour, with a history of pregnancy loss or bleeding, or those with clotting disorders.

2. Contains Anti-inflammatory Properties 

Several research on ginger shows that gingerol has strong anti-inflammatory and antioxidant effects. 

For example, it may help lower oxidative stress, which happens when there are too many free radicals in the body.

Medical researchers also recommend more studies to determine the best doses and types of ginger extract to use.

Similarly, a 2015 review found that taking ginger by mouth is “modestly effective and reasonably safe” for treating inflammation from osteoarthritis. However, the researchers pointed out that the studies they analyzed were small and might not apply to everyone.

3. May Improve Brain Function and Protect Against Alzheimer’s Disease

Animal studies indicate that the antioxidants and bioactive compounds in ginger can reduce inflammatory responses in the brain, potentially helping to prevent cognitive decline. Oxidative stress and chronic inflammation are thought to play a significant role in Alzheimer’s disease and age-related cognitive decline.

However, research on ginger benefits and side effects shows that it contains compounds like 6-shogaol and 6-gingerol, which might help prevent degenerative diseases such as Alzheimer’s, Parkinson’s, and multiple sclerosis.

4. Can Help Treat Chronic Indigestion

Ginger may improve digestion by increasing movement through the digestive tract, potentially preventing constipation. It seems to positively affect pancreatic lipase, an enzyme that aids digestion in the small intestine.

Functional dyspepsia, which involves symptoms like belching, nausea, abdominal pain, bloating, fullness without a clear cause, often occurs with irritable bowel syndrome (IBS) could also be managed by ginger.

Likewise, according to a study on ginger benefits and side effects, consuming ginger and artichoke preparation taken before a main meal significantly improved indigestion symptoms in people with functional dyspepsia compared to a placebo.

5. May Improve Heart Disease Risk Factors and Lower Blood Sugar 

There is also some evidence that ginger may benefit heart health. A study found that consuming ginger daily protects against various cardiovascular conditions like high blood pressure. 

Another study showed that ginger extract reduced heart abnormalities in diabetic rats, likely due to its antioxidant properties. 

Some researches suggest that ginger might help manage blood sugar levels as well.

6. May Help with Weight Loss

Studies on ginger benefits and side effects in both humans and animals suggest that ginger might aid in weight loss. Ginger might help with weight loss through various mechanisms, including its potential to lower inflammation.

A research found that ginger supplements significantly reduced body weight, waist-hip ratio, and hip ratio in people who were overweight or obese. 

7. Supporting the Immune System

Many people use ginger to help recover from a cold or the flu, although the evidence for this is mostly based on personal experiences. Ginger contains properties that fight infections. A certain study found that fresh ginger might help protect the respiratory system from certain viruses, while dried ginger did not have the same effect.

Another study suggested that daily ginger consumption might support the immune system, potentially protecting against chronic diseases and aiding recovery from illnesses like the common cold or flu. 

8. May Reduce Menstrual Pain

Ginger might help relieve menstrual pain, also known as dysmenorrhea. This could be through the anti-inflammatory and pain-relieving effects of its gingerol compounds. Some research on ginger benefits and side effects suggests that ginger could be as effective as acetaminophen/caffeine/ibuprofen (Novafen) for easing this type of pain. 

9. May Help Lower Cholesterol Levels

A research discovered that consuming ginger significantly lowered triglycerides and LDL cholesterol while increasing HDL (good) cholesterol. Even small doses of less than 1,500 mg per day were effective. 

note that adding such high doses of ginger into your diet might be challenging, especially if you don’t enjoy its taste.

10. Can Help Fight Infections

Ginger’s antimicrobial properties might make it helpful in fighting bacterial and fungal infections.

Lab studies on ginger benefits and side effects have shown that ginger may be effective against Escherichia coli (E. coli), which can lead to intestinal infections; Candida albicans (C. albicans), responsible for fungal infections in the mouth, vagina, and other areas; and Staphylococcus aureus (S. aureus), which causes various diseases.

11. May Help Reduce Cancer Risk

Although many studies on ginger concentrating on cancer risk haven’t involved humans, research shows that ginger is a rich source of antioxidants. 

These antioxidants can reduce oxidative stress, which occurs when too many free radicals build up in the body. This buildup can cause cellular damage, potentially leading to conditions like rheumatoid arthritis, heart attacks, chronic inflammation, and cancer.

A recent study suggested that ginger might be effective against certain gastrointestinal cancers by inhibiting cancer cell growth or promoting cancer cell death. However, more research is needed to confirm these effects in humans.

Ginger benefits for women

While ginger is likely safe during pregnancy and breastfeeding, it’s best to consult a healthcare professional first. The FDA considers ginger safe as a food, but it does not regulate its use as a medicine or supplement. Many of the compounds in ginger haven’t been thoroughly studied, and not all claims about its healing properties are scientifically supported. 

Before adding more ginger to your diet or taking a ginger supplement, it’s important to Speak to a Doctor, as some supplements may interact with medications or cause other health issues.
