Ginger is a warming spice with a stimulating effect on the body. I have recommended ginger to treat Vertigo and motion sickness. Ginger has been recommended to alleviate nausea, and it is a safe remedy for morning sickness.
It is also used to help colds, indigestion, joint pain, diarrhea and nausea; ginger has analgesic, sedative, and antibacterial properties and it contains essential fatty acids, phytochemicals, iron, magnesium, manganese, phosphorus, potassium, B-vitamins, and zinc.
I especially like Ginger for its anti-inflammatory properties. It is useful for treatment of most kinds of arthritis and offers a big advantage over NSAIDs and aspirin, both of which are irritating to the stomach.
The underground stem, or rhizome, is the part that is used as a spice; it is in the same family as turmeric and cardamom. There are several forms of ginger: fresh, dried, pickled, preserved in syrup, crystallized and powdered.
Excessive doses of ginger may cause mild heartburn, diarrhea and irritation of the mouth; it may also cause some mild gastrointestinal side effects, such as belching, heartburn, or stomach upset. This may be controlled by taking ginger supplements in capsules.
