Simply put, hydrosol is the aromatic water that remains after steam-distilling botanical material. During essential oil distillation, pressurized steam passes through the plant product extracting the essential oils contained within the plant material. The steam and oil are condensed, the essential oil is decanted from the top of the oil/water mixture, and the water-based product left is hydrosol.
Hydrosol contains trace amounts of essential oils, as well as other hydrophilic (water-soluble) compounds native to the plant material. Generally speaking, the hydrosol contains the water-soluble chemicals from the plant, while the essential oil contains the hydrophobic, or non-water-soluble, chemicals. This helps explain the subtle differences in aroma and therapeutic quality between the essential oil and hydrosol derived from the same plant. Hydrosols still have the beautiful scent of the plant but tend to be gentler in nature.

Essential Oil and Hydrosol Distillation

In her book Hydrosols: The Next Aromatherapy, Suzanne Catty states the following, “Hydrosols contain all of the plant in every drop… Here we have the water-soluble components, the essential-oil molecules, the very fluid that was flowing through the plant cells when the plant was collected. It’s all there in a matrix of water that is so much more than water…”.
It’s important to note that hydrosols are not simply essential oils blended into the water to form a mixture, rather they are the result of essential oil distillation. The best hydrosols are distilled from fresh, vibrant plant material and aren’t a byproduct of an essential oil distillation – they are the focus of the distillation!

Hydrosol Safety and Storage

There are some things to consider when working with hydrosols. Hydrosols have a 1-2 year shelf life and should be used within this period to avoid bacterial growth and keep the therapeutic vibrancy this product intact. Hydrosols are perfect candidates for the refrigerator! If you do notice any kind of bloom-forming in your hydrosol, you would want to replace this product with a fresh batch right away. Hydrosols do best in a sterile environment and anytime you are putting hydrosol into a bottle, and you want it or a blend to last for more than 1 week, you would want to sterilize the container with grain alcohol before filling it with hydrosol.
Hydrosols are gentle and perfect for young kids and children in general. A little German chamomile on a bruise or scrape is perfect for active kids to help them heal even faster from injury. A teaspoon of elderflower hydrosol in a tall glass of water can really help boost the immune system.
