Ginger Also known asAfrican Ginger, Black Ginger, Gan Jiang.

Scientific name: Zingiber officinale.

Botanical Family: Zingiberaceae.

Part used: The parts of ginger used medicinally are the rhizome (root-like stem) and root.

Traditional use.

Ginger is used for: motion sickness, morning sickness, colic, dyspepsia, flatulence, chemotherapy-induced nausea, rheumatoid arthritis, osteoarthritis, loss of appetite, nausea and vomiting following surgery, and migraine headaches. It is also used for upper respiratory tract infections, coughs, bronchitis, for the promotion of sweating, as a circulatory stimulant and for treating stomach-ache, diarrhea and nausea for any reason.

Ginger is commonly used as a flavoring agent in foods and beverages.



There are no concerns regarding safety when used appropriately. Ginger has been safely used in several clinical trials.(1,2,3,4,5,6,7,8,9,10,11,12,13)


Pregnancy: There are no concerns regarding safety. Studies in pregnant women suggest that ginger can be used safely and effectively for morning sickness without harm to the fetus. As with any medication given during pregnancy, the potential benefit to risk must be weighed. See dose guidelines for use in pregnancy.


Breastfeeding: There are no problems with food levels of ginger in the diet. No scientific studies have been undertaken on therapeutic doses. All herbs and spices cross into breastmilk so only use therapeutic doses of ginger if there is a clinical indication that warrants therapy, weighing up relative risks and benefits of using the herb.


Volatile oil; predominantly hydrocarbons including zingiberene, ar-curcumene and bisabolene.

Pungent principles; a mixture of phenolic compounds with carbon side chains. These are referred to as gingerols, gingerdiols, gingerdiones, dihydrogingerdiones and shaogaols. The shaogoals are formed during the drying process and are twice as pungent as the gingerols. Hence the dried ginger is more pungent than the fresh herb.


Oleoresin; including gingerol homologues including derivatives with a methyl sidechain.


6-gingesulphonic acid.

Starch, proteins (amino acids including arginine) and fat.

Vitamins; including niacin, and vitamin A.


Scientific evidence.

Morning sickness. Taking ginger orally seems to reduce the severity of nausea and vomiting with morning sickness. Ginger seems to be more effective than placebo and comparable to vitamin B6. (1,4,10,14,15,16)

Vertigo. Taking 1 gram of ginger orally seems to reduce symptoms of vertigo, including nausea.(9)

Osteoarthritis. Severalstudies have shown evidence of symptom relief as effective as ibuprofen and diclofenac (NSAIDs). One study showed benefit after twelve weeks of treatment. (5,6,7,23,24,25)

Muscle Soreness. One study showed reduction in muscle soreness in women. (26)

Painful periods. Two recent clinical trials in women demonstrated that  ginger for 3 days from the start of their menstrual period was as effective as mefenamic acid (Ponstan) and ibuprofen (Nurafen) and placebo in relieving period pain. (27,28)

Migraine headache. Anecdotal evidence suggests that ginger might reduce the severity and duration of migraine headache.(9)


Mechanism of action.

Active constituents of ginger include gingerol, gingerdione, shogaol, and sesquiterpene and monoterpene volatile oils.(17,18) The chemical constituents of ginger vary among fresh, semi-dry, and dry forms of ginger.(17) Ginger has a variety of pharmacological properties including; lowering fever, analgesia, cough inhibition, anti-inflammatory, sedative, antibiotic, weak antifungal, and other properties.(19,17)


The mechanism by which ginger reduces nausea and vomiting might be due to the 6-gingerol constituent.(20) Other ginger constituents such as 6-shogaol and galanolactone seem to act on serotonin (a chemical transmitter in the nervous system, especially in the brain and gut) receptors.(20) Galanolactone seems to act primarily on serotonin receptors in the small intestine. Ginger has been shown to possess free radical scavenging, antioxidant, inhibition of lipid peroxidation and that these properties might have contributed to the observed gastro-protective effects.

Ginger is sometimes used for inflammatory conditions such as osteoarthritis and rheumatoid arthritis. Some researchers speculate that certain constituents of ginger might inhibit pro-inflammatory enzymes.(21) Compounds found in ginger are capable of inhibiting PGE-2 production and that the compounds may act at several sites.(29)



Adverse reactions.

Ginger is usually well tolerated when used in usual doses.


Interactions with herbs and supplements.

None reported.


Interactions with drugs.

None reported.

Interaction with warfarin is generally cautioned. However a study showed that in healthy subjects there was no alteration in the metabolism of warfarin.(30,31) Undertake weekly monitoring for one month as an additional precaution.


Interactions with foods.

None known.


Interactions with laboratory tests.

None known.



Recommended dose: 1.5-6mls per day 1:5 tincture 70% alcohol.

Or for a stronger 1:2 tincture 90% alcohol the dose is from 0.25-0.5ml per day.

Decoction: range from tsps. per day.

Powder/capsule: range from 0.75-3gms per day.


Oral: For morning sickness, 250 mg ginger 4 times daily, or 500 mg twice daily, has been used. (1,4,12,18) A higher dose of 650 mg 3 times daily has also been used.(16) It may take 3-4 days of regular use to be effective. For motion sickness, 1 gram of dried powdered ginger root 30 minutes to 4 hours before travel has been used.(8,22)
