Areca nut, commonly known as betel nut, is the fruit of the Areca palm (), which is found in tropical areas of the Pacific, south Asia and eastern Africa. The major use of areca nut is as a recreational stimulant typically chewed wrapped in betel leaves (), powdered with calcium hydroxide (slaked lime), and flavored with mint, clove or tobacco. Areca nut has also been used as an extract in traditional medicine as a cathartic or as treatment of intestinal parasites. Areca nut has not been linked to cases of clinically apparent acute liver injury, but epidemiologic studies from Asia have found a strong link between habitual betel nut chewing and oral cancer, and it may also increase the risk of cirrhosis and hepatocellular carcinoma.
槟榔，通常被称为槟榔果，是槟榔树的果实，生长在太平洋、南亚和东非的热带地区。槟榔的主要用途是作为一种消遣性兴奋剂，通常与蒌叶一起咀嚼，加入氢氧化钙（熟石灰）粉末，并添加薄荷、丁香或烟草调味。槟榔也被用作传统医学中的提取物，用作泻药或治疗肠道寄生虫。槟榔与临床明显的急性肝损伤病例没有关联，但亚洲的流行病学研究发现，习惯性咀嚼槟榔与口腔癌之间存在密切联系，它还可能增加肝硬化和肝细胞癌的风险。
