▎精油簡介
優選產自馬達加斯加東部雨林，是地球生態系統中的一顆「璀璨明珠」，擁有獨特的地理位置，島上各地氣候差異較大，低緯度、全年高溫多雨的東部的熱帶雨林氣候為羅文莎葉提供了優質的生長環境。
由於多受日光直射的作用，羅文莎葉葉片也蘊含了滿滿的有效精粹。因為其對幫助人們身體健康有著不凡的表現，被譽為馬達加斯加的國樹，當地總統府內外也種植著多株樹齡200年以上的羅文莎葉樹。
羅文莎葉精油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。
▎成分解析
｜主要成分：氧化物
主要成分為桉油醇(具有疏解黏液的作用)，α-Terpineol萜品醇，另外還有微量成分，如:α-蒎烯、香檜烯、檸檬烯等。
▸ 羅文莎葉具有苯丙烷，木脂素，類黃酮，香豆素和萜類化合物等成分，在體外試驗對於發炎有相關研究。
｜成分1：1.8-桉油醇 (1,8 cineole)
▸ 化學特性：高達62.6%的氧化物(1.8-桉油醇)成分，使得羅文莎葉精油對呼吸系統的調節變得更加強大，上揚清新的氣味能提振情緒，同時還能激發人體對環境抵抗的機制。
▸ 一項體外實驗顯示1.8-桉油醇可刺激單核白血球，進而調解細胞素LTA4和前列腺素PGE2生成，它們都是花生四烯酸AA代謝途徑。顯示1,8-cineole適合治療支氣管不適。
｜成分2：萜品醇(α-Terpineol)
萜品醇(也稱松油醇)，具紫丁香香氣，是常用的化合物，如α-T和T-4-on，對人類，動物以及植物都具有廣泛的不同生物學作用。
- 用途：它們不僅是用於香水，化妝品和家用清潔產品的流行香料成分，而且還用 於調味食品和飲料。它們還具有多種重要的生物學和藥物特性。此外萜品醇也用於肥皂、農藥、醫藥、塑料、電訊和儀 表工業中，亦用作玻璃器皿上色彩的溶劑。
