Hydrosols and Floral Waters 

What is a Hydrosol? This term is derived from the Latin words hydro and sol meaning "water solution".  Hydrosols come by many names including floral waters, herbal distillates, hydroflorates all of which are pertaining to the water that is a by-product of creating essential oils.    

In my case, I only collect essential oil for lemon grass. Flowers produce very little essential oils.

 纯露/花水

纯露,又称水精油(Hydrolate),是指精油在蒸馏萃取过程中,在提炼精油时分离出来的一种100%饱和的蒸馏原液,是精油的一种副产品,成份天然纯净,香味清淡怡人。
纯露就是芳香植物蒸馏所得的冷凝水溶液。在蒸馏萃取过程中油水会分离,因密度不同,精油会漂浮在上面,水分则沉淀在下面,这些水分就叫纯露。纯露中除了含有少量精油成分之外,还含有全部植物体内的水溶性物质。拥有百分之百植物水溶性物质的纯露,其所含矿物养分(如单宁酸及类黄酮)是精油所缺乏的。其低浓度的特性容易被皮肤所吸收,完全无香精及酒精成份,温和不刺激,纯露可以当做每天使用,亦可替代纯水调制各种面膜等。

到目前为止,我只在蒸馏柠檬香茅才有收集精油,其他的都属饱和纯露。
