The term hydrosol designates the aromatic water that remains at the end of the distillation process of essential oils. The hydrosol is, therefore, the water that has been used for the distillation of the plants and which is little loaded with aromatic molecules that have not been grouped together in the essential oil. Hydrolat is, in fact, the generic and technical term that describes the aqueous product of distillation, regardless of the part of the plant distilled (flower, leaf, root, twigs, bark, etc.), whereas the term floral water should specify the flowery nature of the hydrosol. The lavender hydrosol collected in this photo notably has refreshing, purifying, cleansing, softening, healing, anti-infectious, anti-inflammatory, and astringent properties for the skin.
