Armpits laced with lemon juice
In Puerto Rico it is common practice to rub a slice of lemon in one’s armpit before commencing a night of drinking. Puerto Rican lore states that lemon prevents sweating, which thereby retains internal fluids and thus prevents dehydration and headaches.
Sweating it out
According to Native Americans, the best way to rid oneself of a night of drinking and debauchery is to kick up a sweat, lick that sweat and then spit it out.
There are also various animal-laced cures around the world for hangovers. Mongolians drink pickled sheep’s eyes in tomato juice; cowboys used to drink tea with rabbit droppings; some Vietnamese people crush Rhino horns into hot water; and Sicilians eat a dried bull’s penis.
