肉桂，在当地被称为madeu，是南太平洋东卡罗来纳州波恩佩岛火山山脉的特有树种。这种树皮是从树上收获的，并被酿造成药茶和热饮，经常被消费。许多品种的肉桂含有已知的致癌物质黄樟素，这引发了人们对这种饮料习惯性消费的担忧。高效液相色谱分析证实，在0.435%(w/w)的香桂树皮的乙醇提取物中存在致癌物质，但在茶叶中未检测到黄樟素。黄樟素的检出限为1.2 5μg/m L，定量下限为3.75 m in g/m L。传统的制备方法是煮树皮屑，会降解黄樟素。
Cinnamomum carolinense, locally known as madeu, is a tree endemic to the volcanic mountains of the Island of Pohnpei in the Eastern Carolines of the South Pacific. The bark is harvested from trees and brewed to make a medicinal tea and hot beverage that is regularly consumed. Many species of Cinnamomum contain the known hepatocarcinogen safrole, sparking concern regarding habitual consumption of this beverage. HPLC-PDA analysis confirmed the presence of the carcinogen in alcoholic extracts of Cinnamomum carolinense bark shavings (0.435%, w/w), but safrole was not detected in the tea. The limit of detection and limit of quantitation of safrole were determined to be 1.25 and 3.75μg/mL, respectively. The traditional preparation method, which boils the bark shavings, degrades the safrole.
