An October 2021 paper (1) suggests that ginger extract suppresses inflammatory arthritis. Here is what the researchers said: “Rheumatoid arthritis (RA) is a disabling inflammatory disorder. Ginger is used for food and medicine to treat arthralgia, sprains, and muscle aches. Anti-inflammatory effects of ginger have been observed.” In this animal study, rats with induced arthritis were treated with ginger extract. It was found that ginger could suppress NF-κB activity (pro-inflammatory gene activity) and Wnt pathway (an inflammation regulatory system).
