Ginger is being tested as an alternative to painkillers for toothache.

The spice is a traditional remedy for ailments such as diarrhoea and nausea, but scientists are assessing its effect on stopping dental pain and swelling following the removal of impacted teeth.

Researchers conducting the study at the Qazvin University of Medical Sciences in Iran say ginger contains chemicals that have the benefits found in some painkillers, but cause fewer side-effects.

“The effectiveness of ibuprofen in the treatment of post-operative dental pain has been investigated in several clinical trials, but drugs such as this cannot be used in patients with gastrointestinal ulcers, bleeding disorders or renal problems,” they say.

“There is a need for an effective oral painkiller with a more favourable safety profile.”

Patients taking part in the study will take capsules containing 500mg ginger powder every six hours for five days. - Daily Mail
