H****s 发帖数: 1130 | 1 香薰油,Essential oils, or 'essences' as they are also called,
are highly concentrated substances extracted from various parts of aromatic
plants and trees.
通常萃取自植物的花、叶、根、籽、皮、果、茎等部位。
和一般的vegetable oil不同,比如corn and olive, 香薰油极易挥发。
构成的化学成分也极其复杂,大多数都有上百种成分,such as terpenes, alcohols,
aldehydes, and esters.
因此,单一的香薰油的作用就很多。
例如,lavender(薰衣草),就有antiseptic, antibacterial, antibiotic, antidepr
essant, analgesic,
decongestant and sedative的特性。 |
