What is an essential oil?/什麼是精油

Essential oils are natural aromatic compounds found in the seeds, bark, stems, roots, flowers, and other parts of plants. They can be both beautifully and powerfully fragrant. If you have ever enjoyed the gift of a rose, a walk by a field of lavender, or the smell of fresh cut mint, you have experienced the aromatic qualities of essential oils. In addition to giving plants their distinctive smells, essential oils provide plants with protection against predators and disease and play a role in plant pollination. 

Essential oils are non water-based phytochemicals made up of volatile organic compounds. Although they are fat soluble, they do not include fatty lipids or acids found in vegetable and animal oils. Essential oils are very clean, almost crisp, to the touch and are immediately absorbed by the skin. Pure, unadulterated essential oils are translucent and range in color from crystal clear to deep blue.

Try this at home: Squeeze the peel of a ripe orange. The fragrant residue on your hand is full of essential oils.

In addition to their intrinsic benefits to plants and being beautifully fragrant to people, essential oils have been used throughout history in many cultures for their medicinal and therapeutic benefits. Modern scientific study and trends towards more holistic approaches to wellness are driving a revival and new discovery of essential oil health applications.

精油是什麼?

精油是由種子、樹皮、樹幹、樹根、花卉和植物的其他部位所提煉的自然萃取物。它們的香味既能提供美好的感覺又具有保健益處。任何人只要有機會嗅嗅玫瑰花、走過一片薰衣草田或聞聞新鮮的薄荷葉，就已經體驗到精油芳香的奇妙特質了。精油可以提振心情，舒緩情緒和引發情懷，但，精油的好處絕不僅是氣味芳香而已，還可以保護植物不受蟲害侵入，並在花粉的傳授上擔任重要的角色。

精油是非水質的植物化學物質，由具揮發性的有機物質所組成。雖然是油溶性的，但是並不含有植物油和動物油中的飽和或不飽和脂肪酸。精油的質地非常純凈，幾近清爽，能立即被皮膚吸收。完全純質的精油是半透明的，顏色從晶瑩無色到深藍色都有。

在家試試看：用手擰擠一個成熟的橘子，手上留下的芳香油脂，就是精油。

除了對植物本身固有的利益和帶給人類芳香的氣味之外，精油在整個人類歷史的各文化中一直因為它的效果而廣受利用。現代的科學研究和趨勢越來越朝著整體健康的方向前進，這種趨勢促使人們對精油在健康上的效益又再度有了新的發現和關注。

大體而言,精油是從植物的根莖葉花困實,種子和其他部位,萃取而來的.在西方,精油的使用就如同東方的藥草一樣是用來治療,保健的,唯一不同的是,咱們的中藥草,採收的藥草要先曬乾烘乾來保存,否則發霉,在烘乾的同時藥草的活性流失了,藥效當然也就大大打了折扣了.所以我們煎藥,才能把其中的藥效精華釋出.但精油不同,精油要從大量,活生生的原料中萃取出少量的精華,所以精油保留了植物100%的活性,所以精油的效能比通藥草效力強50-70倍.最重要的是,精油是完全沒有副作用的.doTERRA Taiwan
