Hydrosols, also known as floral waters, hydroflorates, flower waters or distillates are products from steam distilling plant materials. Hydrosols are like essential oils but in far less of a concentration. When a distiller brews plant material with water in a large cooker the steam fills the pot and, as it rises, it causes the glands of the plants to burst and release the oils and essence of the plant into the steam. The oil rises through a condenser and collects in a separate vessel. This is what we know as essential oil, but what about all that fragrant water that was steamed with the original plant material? That is our hydrosol, or floral water.
Hydrosols are usually the result of essential oil production as a by-product but the highest quality hydrosols come from the devoted distillers who, with artist like precision steam the floral and plant material strictly to produce a hydrosol. Hydrosols contain all of the essence of the plant in every drop, just like essential oils but in a milder form; making them suitable for all manner of applications where essential oils would be too strong.
Clinically, the chemical components in the hydrosol are primarily acids. Why do they work? Because they acidify the water or the product and bacteria do not live well in acidic environments. This is why acidic liquids such as vinegar make good preservatives for food items. Acidic environments are astringent and so the hydrosols are useful in skin care products as astringents constrict and contract the tissues. Hydrosols can be used externally in skin care products, taken as a tonic or combined in a beverage drink. We love using hydrosols for room/linen aromatherapy sprays. The Medicine Garden hydrosols all come in a spray bottle.
