▎精油简介

甜桦树（Betula lenta）又称「桦木」，也称为「黑桦树」、「樱桃桦树」、「桃花心木桦树」或「香料桦树」，相较其他桦木，是较为矮小的树种，有明亮的绿叶与深红棕色的芳香树皮。具甜美的木质香气，类似白珠树的味道，主要化学成分含有水杨酸甲酯，是阿司匹林的主要成分之一。

甜桦木精油是从该树木的树皮中蒸汽蒸馏而来，在蒸馏前必须将树皮浸软、浸湿至12个小时，这种精油具有香甜的、刺鼻的、薄荷的、新鲜的、樟脑香气，让人联想到杀菌药膏。目前桦木精油质量较好的产区为美国。

▎成分解析

｜主要成分：酯类

透过水蒸馏获得的天然甜桦木精油中鉴定出60 多种化合物。油主要是水杨酸甲酯(93.24-99.84%)，次要成分o-愈创木酚、藜芦醇、2- E -4- Z -癸二醛和2- E -4- E -癸二醛被确定为正宗甜桦木油的天然基本化合物。

｜研究认证

▸ 复方水杨酸甲酯由多种成分组成，如水杨酸甲酯、薄荷醇、樟脑、氯菲安敏、百里酚等，在临床使用中是可信赖的。

▸ 含有水杨酸甲酯和L-薄荷醇的局部镇痛剂可加速运动引起的体温过高的皮肤冷却过程中的热量损失。
