- Dosing considerations for Ginger.
Ginger is commonly used to treat various types of "stomach problems," including motion sickness, morning sickness, colic, upset stomach, gas, diarrhea, irritable bowel syndrome (IBS), nausea, nausea caused by cancer treatment, nausea caused by HIV/AIDS treatment, nausea and vomiting after surgery, as well as loss of appetite.
Other uses include pain relief from rheumatoid arthritis (RA), osteoarthritis, menstrual pain, upper respiratory tract infections, cough, respiratory problems, migraine headache, bronchitis, and diabetes. Ginger is also sometimes used for chest pain, low back pain, and stomach pain, discontinuing use of drugs called selective serotonin reuptake inhibitors (SSRIs), anorexia, to stimulate breast milk, as a diuretic, and to increase sweating. It is also used to treat cholera, bleeding, bacterial bloody diarrhea, baldness, malaria, inflamed testicles, poisonous snake bites, and toothaches.
Some people pour the fresh juice on their skin to treat burns. The oil made from ginger is sometimes applied to the skin to relieve pain. Ginger extract is also applied to the skin to prevent insect bites.
In foods and beverages, ginger is used as a flavoring agent.
In manufacturing, ginger is used as for fragrance in soaps and cosmetics.
One of the chemicals in ginger is also used as an ingredient in laxative, anti-gas, and antacid medications.
Ginger might also help prevent morning sickness, but it should not be used for this purpose. The safety of ginger in pregnancy has not been proven.
There is also evidence that ginger can relieve joint pain and help movement in people who have rheumatoid arthritis. But ginger doesn't seem to be helpful for people with another kind of arthritis called osteoarthritis.
There isn't enough information to know if ginger is effective for the other conditions people use it for including: upset stomach, loss of appetite, colds, flu, and others.
Possibly Effective for...
- Nausea and vomiting caused by HIV/AIDS treatment. Research suggests that taking ginger daily, 30 minutes before each dose of antiretroviral treatment for 14 days, reduces the risk of nausea and vomiting in patients receiving HIV treatment.
- Painful menstrual periods. Research shows that taking ginger powder 500-2000 mg during the first 3-4 days of a menstrual cycle modestly decreases pain in women with painful menstrual periods. Some specific doses that have been used include 500 mg of ginger three times daily and a specific ginger extract (Zintoma, Goldaru) 250 mg four times daily. Doses were given for 3 days starting at the beginning of the menstrual period. The specific ginger extract (Zintoma) seems to work about as well as the medications ibuprofen or mefenamic acid.
- Morning sickness. Taking ginger by mouth seems to reduce nausea and vomiting in some pregnant women. But it might work slower or not as well as some drugs used for nausea. Also, taking any herb or medication during pregnancy is a big decision. Before taking ginger, be sure to discuss the possible risks with your healthcare provider.
- Osteoarthritis. Some research shows that taking ginger can modestly reduce pain in some people with a form of arthritis called "osteoarthritis." One study shows that taking 250 mg of a specific ginger extract (Zintona EC) four times daily reduces arthritis pain in the knee after 3 months of treatment. Another study shows that using a different ginger extract (Eurovita Extract 77; EV ext-77), which combines a ginger with alpinia, also reduces pain upon standing, pain after walking, and stiffness. Some research has compared ginger to medications such as ibuprofen. In one study, a specific ginger extract (Eurovita Extract 33; EV ext-33) did not reduce arthritis pain as well as taking 400 mg of ibuprofen three times daily. But in another study, taking 500 mg of ginger extract twice daily worked about as well as 400 mg of ibuprofen three times daily for hip and knee pain related to arthritis. In another study, a specific ginger extract combined with glucosamine (Zinaxin glucosamine, EV ext-35) worked as well as the anti-inflammatory medication diclofenac slow release (100 mg daily) plus glucosamine sulfate (1 gram daily). Research also suggests that massage therapy using an oil containing ginger and orange seems to reduce short-term stiffness and pain in people with knee pain.
- Nausea and vomiting following surgery. Most clinical research shows that taking 1 to 1.5 gram of ginger one hour before surgery seems to reduce nausea and vomiting during the first 24 hours after surgery. One study found ginger reduced nausea and vomiting by 38%. Also, applying 5% ginger oil to patients' wrists before surgery seems to prevent nausea in about 80% of patients. However, taking ginger by mouth might not reduce nausea and vomiting in the period 3-6 hours after surgery. Also, ginger might not have additive effects when used with medications for nausea and vomiting. In addition, ginger might not lower the risk of nausea and vomiting after surgery in people who have a low risk for this event.
- Dizziness (vertigo). Taking ginger seems to reduce the symptoms of dizziness, including nausea .
Possibly Ineffective for...
- Preventing motion sickness and seasickness. Most research suggests that taking ginger up to 4 hours before travel does not prevent motion sickness. Some people report feeling better, but actual measurements taken during studies suggest otherwise. But in one study, ginger appears to be more effective than the drug dimenhydrinate at reducing stomach upset associated with motion sickness.
Insufficient Evidence to Rate Effectiveness for...
- Sudden respiratory system failure (Acute respiratory distress syndrome). Research suggests that administering 120 mg of ginger extract daily for up to 21 days increases the number of days without ventilator support, the amount of nutrients consumed, and reduces the time spent in intensive care units in people with sudden respiratory system a failure. However, ginger extract does not seem to affect death rates in people with this condition.
- Nausea and vomiting due to chemotherapy. There is contradictory evidence about the effectiveness of ginger for nausea and vomiting caused by chemotherapy for cancer. Some evidence suggests that taking ginger by mouth might help reduce nausea caused by chemotherapy. However, other evidence suggests that adding ginger is no more effective than standard anti-nausea treatments alone. Reasons for the conflicting results may be the type and dose of ginger used, as well as the time at which ginger treatment was started.
- Chronic obstructive pulmonary disease (COPD). Research shows that taking two capsules of a specific combination product (AKL1, AKL International Ltd) containing ginger twice daily for 8 weeks does not improve respiratory symptoms in people with COPD.
- Diabetes. There is inconsistent evidence about the effects of ginger on blood sugar control in people with diabetes. Some research suggests that taking ginger daily in two divided doses for 8 weeks reduces insulin levels, but not blood sugar. Another study shows that ginger affects blood sugar, but not insulin levels. Although it's not clear, the conflicting results may be due to the dose of ginger used or the length of time the patients had been diagnosed with diabetes.
- Upset stomach (dyspepsia). Research suggests that taking a single dose of 1.2 grams of ginger root powder one hour before eating speeds up how quickly food empties out of the some in people with dyspepsia.
- Alcohol hangover. Early research suggests that taking a combination of ginger, pith of Citrus tangerine, and brown sugar before drinking decreases symptoms of alcohol hangovers, including nausea, vomiting, and diarrhea.
- High cholesterol. Research suggests that taking 1 gram of ginger three times daily for 45 days lowers triglyceride and cholesterol levels in people with high cholesterol.
- Insect bites. Early research suggest that applying Trikatu to the skin, which contains ginger, long pepper, and black pepper extracts, does not reduce mosquito bite size.
- Irritable bowel syndrome (IBS). There is inconsistent evidence about the effects of ginger on IBS symptoms. Some research suggests that taking ginger daily for 28 days does not improve symptoms. However, other research suggests that using an herbal mixture containing English horsemint, purple nut sedge tuber, and ginger tuber three times daily for 8 weeks is as effective as the drug mebeverine at reducing IBS symptoms. But it's not clear if ginger or the other ingredients promote symptom relief.
- Joint pain. Research shows that taking capsules of a specific combination product (Instaflex Joint Support, Direct Digital, Charlotte, NC) containing ginger for 8 weeks reduces joint pain by 37%. But this product does not seem to reduce joint stiffness or improve joint function.
- Speeding up labor. Early evidence suggests that bathing in water containing ginger oil does not shorten the length of labor.
- Migraine headache. Some reports suggest that taking a combination of ginger and feverfew might reduce the length and intensity of migraine pain. However, it is not clear if the effects are from ginger, feverfew or the combination.
- Muscle pain after exercise. There is contradictory evidence about whether ginger helps for muscle pain caused by exercise. Some research shows benefits, while other research does not.
- Recovery after surgery. Evidence suggests that inhaling and applying a combination of lavender and ginger oils to the skin before surgery does not reduce distress in children after surgery.
- Rheumatoid arthritis (RA). There is some early evidence that ginger might be helpful for decreasing joint pain in people with RA.
- Trouble swallowing. Evidence suggests that spraying a product containing ginger and clematix root (Tongyan) to the back of the throat improves severe problems swallowing in stroke victims. However, it is not beneficial in people with less severe problems swallowing.
- Weight loss. Research suggests that taking a supplement containing ginger, rhubarb, astragalus, red sage, turmeric, and gallic acid (Number Ten) daily for 8 weeks does not increase weight loss or reduce body weight in people who are overweight. But other research suggests that taking a combination supplement (Prograde Metabolism) containing ginger and other ingredients twice daily for 8 weeks reduce body weight, fat mass, waist circumference and hip circumference, when used along with dieting. But it's not clear if ginger is the cause for the weight loss.
- Bacterial infection of the intestine (Cholera).
- Discontinuing use of drugs called selective serotonin reuptake inhibitors (SSRIs).
- Loss of appetite.
- Other conditions.
