The above article specifically notes that a ginger product named Zinaxin, produced in Australia, was used in the story - it is formulated from ginger varieties with the greatest anti-inflammatory effects and is enclosed in a capsule that arrives intact in the bloodstream and can be delivered directly to the joints.
Further investigation into the ginger study led me to this site: HealthWatcher.net, a Canadian site that tries to expose quackery. The writers of the articles on Zinaxin are apoplectic over the claims its makers make, based on the above study. Their complaints are two:
- Health Canada has not yet studied this supplement and therefore cannot determine if the claims are valid; and
- The study was conducted for only six weeks, and it appears to healthwatcher that that is not long enough for a disease like osteoarthritis.
