What is it? Umeboshi plums, available in jars at Asian markets and health food stores, reportedly have medicinal qualities.

How does it help? People who eat a lot of meat tend to have very acidic bodies. Umeboshi plums have an alkalinizing effect on the body, which neutralizes fatigue, stimulates digestion and eliminates toxins.

How much? For a normal hangover, bite off about a quarter of a plum and keep it in your mouth until it dissolves. For a whopper hangover, herbalists recommend popping a whole plum into your mouth. Continue to suck on it for about an hour after the plum has dissolved.
