▎精油簡介
茶樹(Tea Tree)為桃金孃科(Myrtaceae)、白千層屬之多年生常綠喬木,它生長在熱帶至亞熱帶地區,沿海沼澤濕地,樹型直立呈圓錐形,具細長如羽毛的葉片,葉線形互生,嫩葉呈黃綠色,成熟時變翠綠色,頂生花序白色瓶刷形,會開黃色或紫色的花。植株高約三米~7公尺,生長速度很快,最早發現於澳洲,因此,也稱為「澳洲茶樹」。
雖然字面直譯為Tee Tree茶樹,但它不是紅茶或其他茶,卻何以有此命名,其實還得從茶樹被發現地說起,在一片四面環繞有茶樹的湖水,傳說由於茶樹的成分滲透湖水,使其變成濃鬱的紅茶色,因此當地人就將四周生長的樹木稱其為Tee Tree。傳說原住民女性在產前、產後或有婦科困擾時,便會浸泡在前述紅茶色湖水中進行自我療愈,所以茶樹自古以來,相傳也是呵護女性的植物。
茶樹具備提升集中力的作用,開啟良好的溝通能力,幫助適應環境,消解工作帶來的疲憊。
