One lab study showed powdered ginger could kill ovarian cancer cells.
In the latest experiments, American scientists gave participants 2g of raw ginger, or a similar amount of heat-treated ginger as some evidence shows heat treatment boosts the spice's potency for 11 days.
A third group was given a placebo. They were then put through a series of testing arm exercises.
The results showed that 24 hours after exercise, pain levels in the raw ginger-eating group were 25 per cent lower than those on the placebo.
And in the heat-treated group, pain levels were 23 per cent lower.
Researchers say this supports anecdotal evidence that ginger has a pain-killing effect. The results have been published in the Journal of Pain.
