BERN, SWITZERLAND—Angered by rising international tariffs against his nation, Swiss president Gunter Klima threatened a worldwide Ricola embargo Tuesday. "If these unfair tariffs are not lifted," Klima said, "we will have no choice but to withhold our natural Alpine-herb throat lozenges, causing billions of throats across the globe to go tragically unsoothed." An estimated 2.1 billion people rely on Swiss menthol for their throat-calming needs.
