原料介绍｜红桧 (Chamaecyparis formosensis)

▎精油简介

优选产自台湾高山，桧木主要分布在海拔1500公尺至2500公尺之间的山地，桧木于冰河时期时落脚于台湾，由于台湾提供相当优异的生长纬度与地理环境，造就了质地优越桧木生态与质量，也让如此珍贵的木材得以保存。

第一批被发现的红桧标本被运往东京，于 1901 年正式命名为台湾红桧。台湾红桧与日本花柏（Chamaecyparis pisifera）为近缘种，在早起都拥有大量的原始林，后因砍伐而产量大减，因此非常珍贵。

台湾桧木为台湾特别的种类，树干皮平滑而薄，木材无辣味，常用于高级建筑及家具建材。

▎成分解析

｜主要成分：倍半萜醇

台湾桧木的桧木醇(Hinokitiol)含量特别高，其自然散发的桧木醇香味能够舒缓紧张的情绪与压力。目前，世界珍贵的台湾桧木已经越来越少了，而树体所分泌的桧木醇能保护自己不受虫蛀与病害的侵袭，故能存活千年以上，而成为人称的神木。

枝干萃取的桧木精油以倍半萜醇类为主，针叶萃取的则以单萜烯类为主。另外还有其他成分，如：桃金娘醇(myrtenol)、桃金娘醛(myrtenyl)、γ-杜松烯(g-cadiene)、松油萜、樟烯、对伞花烃、萜烯醇、樟脑等。
