Mexico's spas combine familiar beauty treatments with indigenous rituals, using local materials like cactus, volcanic ash, chocolate, vanilla and honey. For example, the Four Seasons Resort in Punta Mita, Mexico, offers a tequila-and-sage oil massage, but if that sounds a little too rowdy for your taste, try the hakali massage instead. Hakali involves the application of a warm mixture of cactus. The treatment supposedly removes toxins and rehydrates the skin, leaving you feeling rejuvenated. It costs $180 for 50 minutes of treatment [source: Four Seasons Resort].
