As of May 2015, no medical evidence shows gin-soaked raisins are effective for treating arthritis, according to WebMD. Raisins offer only a minimal amount of anti-inflammatory benefits.
Gin-soaked raisins have become a fairly popular home remedy for arthritis, as noted by About.com. Arthritis sufferers who use this treatment put white raisins in a shallow dish and then pour gin over the raisins. After a few weeks, the raisins absorb some of the gin, while the rest has evaporated. Individuals with arthritis then eat several raisins each day. Most directions for this unproven home remedy recommend nine raisins as the daily dosage.
