Last summer, a group of doctors reported in The Archives of Internal Medicine that an extract from the fruit of the prickly pear cactus, taken in capsule form, was effective in staving off hangover symptoms like dry mouth and nausea.
Perfect Equation of Vista, Calif., financed the research and has patented the extract, which it says is derived from the skin of the prickly pear, Opuntia ficus.
Dr. Linda C. Degutis, an associate professor of emergency medicine and public health at Yale, said hangovers were "incredibly understudied."
