Ginger root is an herbal supplement and cooking spice derived from the Zingiber officinale plant. Historically, ginger root has been used to reduce stomach upset symptoms, including nausea, vomiting and diarrhea, resulting from motion sickness, morning sickness during pregnancy or chemotherapy or anesthesia. Ginger root may also be effective in treating flu-like or cold symptoms. Always consult your medical provider before beginning treatment with an herbal supplement, including ginger root.

For Children

Generally, children between the ages of 2 and 6 should not consume more than 2 milligrams of ginger root each day. However, the maximum amount of ginger root your child may take in a day may vary depending upon body weight. Always consult your child's pediatrician before giving your child ginger root to ensure you provide your child with the correct dose of this supplement.

For Adults

Adults should limit their intake of ginger root to no more than 4 grams daily, the University of Maryland Medical Center reports. This dosage recommendation includes ginger root consumed from food sources, such as ginger bread, ginger ale and ginger snaps.

During Pregnancy

While pregnant, women should not take more than 1 gram of ginger root daily, the University of Michigan Health System reports. Typically, expectant mothers are advised to take 250 milligrams of ginger root up to four times daily to reduce pregnancy-related nausea.


Treatment with ginger root may not be appropriate for everyone. Children under age 2 should not be administered ginger root. If you have gallstones, consult your doctor before taking ginger root, as this supplement may exacerbate your symptoms. Additionally, avoid taking ginger root if you have a personal history of heart problems, a bleeding disorder or diabetes.

Do not take ginger root in conjunction with blood-thinning medications, such as warfarin. This treatment combination may increase your risk of developing bruising or bleeding complications. Ginger root may also significantly lower your blood sugar or blood pressure levels when used in conjunction with diabetes drugs or high blood pressure medications, respectively.

Side Effects

Mild stomach-related side effects may occur following treatment with ginger root. You may experience nausea, heartburn, belching or stomach pain. Diarrhea may also occur and may cause abdominal cramping or bloating. If ginger root comes in contact with your hands or the skin around your mouth, you may experience mild skin irritation, including redness or burning. Typically, these side effects are temporary and subside shortly after treatment. If you experience severe or persistent stomach discomfort after taking ginger root, seek additional care from your primary medical provider.
