   据新华社电 美国研究人员发现,薰衣草和茶树等精油中含有的8种化学物质会干扰人体激素分泌,可能与青春期男孩乳腺组织不正常发育相关。

   薰衣草和茶树精油由数百种化学物质构成。美国国家环境卫生科学研究所研究人员审视其中8种关键成分,在实验室中让它们作用于人体癌细胞,观察可能引起的变化。他们发现,所有8种化学物质均不同程度地激活雌激素,同时抑制睾丸素。这8种化学物质中,4种为薰衣草和茶树精油所共有,另外4种分别存在于两种精油中,部分化学物质存在于其他至少65种精油中。

   植物提取的精油广泛存在于洗发水、乳液、香皂等日用化学用品中。精油同时是颇受欢迎的清洁和医学治疗用品。人体对精油的反应因人而异。研究领头人拉姆齐认为,研究结果显示人们应该慎用精油。“我们的社会认为精油安全,”他说,“然而其中含有多种化学成分,应该谨慎使用,因为一些成分是潜在的内分泌干扰物。”研究人员将向正举行的美国内分泌协会年会报告这项发现。
