Ease a Jellyfish's Sting
The vast majority of jellyfish stings aren't harmful—but even so, the pain can put a damper on your day at the beach. Dr. Oz has a fast-relief remedy: Fill a bucket with vinegar and soak the affected area for 15 to 30 minutes; the acetic acid in the vinegar stops the tiny darts that a jellyfish injects into your skin from releasing more venom. (However, Dr. Oz says that some people are allergic to jellyfish, so if you're experiencing hives or wheezing, seek emergency help ASAP.)
