Osteoarthritis is a common type of arthritis characterized by inflammation and swelling of the joints. It occurs when cartilage, material that cushions the joint, begins to wear away and allow the bones to rub against each other. It is a degenerative condition for which there is no cure, but exercise and drug therapies can help to prevent further cartilage loss and alleviate pain. Some herbs, including ginger, have anti-inflammatory effects and may help to alleviate symptoms. Don't use ginger in place of drugs your doctor prescribes, as evidence to prove it works is limited.
Properties
Ginger is commonly used to flavor foods and drinks, but may have also have therapeutic properties. According to the Memorial Sloan-Kettering Cancer Center, it is sometimes used as an alternative treatment for a variety of conditions including indigestion, colic and arthritis. It contains a number of biologically active chemicals, including monoterpenes, volatile oils and amino acids. An article published in the Summer 2005 issue of the "Journal of Medicinal Food," notes that ginger modulates biochemical pathways activated in chronic inflammation.
Administration
Ginger can be taken in a variety of ways, either as a tea or liquid tincture, or in capsules or tablets. You can also eat this herb raw. The University of Maryland Medical Center suggests taking up to 2 g of ginger per day, in divided doses, to help reduce joint inflammation and pain. Ask your health care provider whether this dose is suitable for you.
Effectiveness
The results of a randomized, placebo-controlled clinical trial that included 261 patients with osteoarthritis of the knee, published in the November 2001 issue of "Arthritis and Rheumatism," found that standardized ginger extract had a statistically significant effect on reducing symptoms of osteoarthritis of the knee. More up-to-date studies are lacking, but research by T. Therkleson, published in the October 2010 issue of "Journal of Advanced Nursing," found that applying a ginger compress to affected joints improved comfort and, joint flexibility and mobility.
Side Effects and Contraindications
RxList notes that ginger is safe for most people, but adds that it may cause side effects including heartburn and stomach upset. Applying a ginger compress to affected joints may irritate the skin. Ginger is not a suitable remedy for everyone. Don't use it if you have a bleeding disorder or diabetes. Also avoid it if you have a heart condition. It may also add to the effects of diabetes medicines and anticoagulants.
