Produced from steam-distilling plant materials. Hydrosols have similar properties to essential oils but are much less concentrated. True steam-distilled hydrosols contain all the beneficial components that whole plant materials have to offer.
Hydrosols are usually a by-product of essential oil production, but the highest quality comes from devoted distillers who, with artist-like precision, steam small batches of fresh floral and plant material strictly to produce hydrosol!
