All about hydrosols
What is hydrosol?
Hydrosols are aromatic waters.
When aromatic plant material is steam distilled, the water becomes infused with the plant’s water-soluble components.
Here’s how it works…
- The botanical material is loaded into a still along with pure water. (At Aromatics, we use pristine mountain well water).
- Pressurized steam passes through the plant, breaking open its essential oil “sacs.”
- As the steam passes through a cooling coil, it condenses back into a liquid—a combination of water and essential oil.
- The essential oil naturally separates, floating to the top.
- And the water is now hydrosol!
Hydrosols offer aromatherapists another way to work with therapeutic plants, which has gentler effects than essential oils.
Hydrosol vs essential oil: how are they different?
Simply put, the hydrosol is a water-based product, while the essential oil is… well, oil! A hydrosol contains the plant’s hydrophilic (water-loving) components, while the essential oil contains its lipophilic (fat-loving) components. Hydrosols do contain very small trace amounts of essential oil, but not enough to where the oil will separate and float to the top (you don’t have to shake a hydrosol before using it).
In her book, Hydrosols: The Next Aromatherapy, author Suzanne Catty says:
“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…”
When essential oils aren’t the right choice, hydrosols give aromatherapists a more delicate option to work with.
And using a hydrosol in addition to an essential oil allows an aromatherapist to get the full spectrum of the plant’s benefits—the oil-based components and the water-based ones.
Another interesting difference between hydrosols and oils is their aromas. Since the two substances contain different components, an essential oil and hydrosol produced from the same plant will often (but not always) have different aromas. For example, myrrh hydrosol often smells different from myrrh essential oil. Lavender hydrosol, however, smells similar to lavender essential oil.
Using hydrosols safely
Another difference between hydrosols and essential oils is that hydrosols tend to be much gentler in nature.
The safe, effective practice of aromatherapy relies on a common principle of natural care: less is more.
We want to give the body what it needs to rebalance itself, without becoming overwhelmed. “Less is more” is also better for the plants, as we use ecologically sustainable practices to harvest only what we need, and use every part of the distillation.
Hydrosols can help rebalance the body, especially when used regularly. While they’re gentler than essential oils, their effects can be profound.
Most hydrosols can be applied to your skin undiluted, without concerns that they’ll cause irritation. Spraying them directly onto your face is generally safe, and some hydrosols—such as German chamomile and cornflower—are even gentle enough to use in a compress for your (closed) eyes. People with sensitive skin tend to love the soft yet soothing effects of hydrosols.
Hydrosols can even be used for babies and animals. (You’ll learn more about using hydrosols for babies in the “Using Hydrosols for Kids” section below. For animals, you should always let the animal choose whether or not it wants a hydrosol, instead of immediately spraying it on the animal’s skin or fur.)
*Though hydrosols do contain trace amounts of essential oils, the quantity of oil present is so small that it doesn’t render the hydrosol unsafe to drink. That said, some are unsuitable for drinking either because they don’t taste good, or their components are too strong. Check each hydrosol’s individual product page on our website to see its specific safety guidelines.
Benefits & uses of hydrosols
Hydrosols can add so much natural beauty to your daily life!
For example, you can incorporate them in your skin care. Use them to make water-based cleansers, and to tone your skin to help reduce breakouts. If your face often feels warm and red, a few sprays with lavender or rose hydrosol can help quiet your complexion and cool you down.
Hydrosols are also excellent for natural cleaning. Use them to freshen your home by themselves, or blend with them to customize your own cleaning products. Learn more in chapter 4 of our free learning guide, Going green at home: Natural cleaning with essential oils:
Along with skin care and natural cleaning, here’s a short list of more ways you can use hydrosols every day…
- Air freshener
- Belly support
- Beverage flavoring
- Care for damaged, sore skin
- Cool hot, tender skin
- Facial toner
- Immune support
- Insect repellent
- Linen spray
- Lymph support
- Open your breath
- Perfume sprays
- Relieve stress and anxious feelings
Hydrosol safety & storage
Since they’re water-based products, hydrosols are best stored in a sterile, cool environment to avoid bacterial growth. (They’re perfect candidates for the refrigerator!)
If they’re stored well, hydrosols can have a shelf life of 1 to 2 years.
Any time you’re pouring a hydrosol from one container into another, it’s best to sterilize your new container with grain alcohol first. And if you ever notice any kind of bloom forming in your hydrosol—or in blends you’ve made with hydrosol—don’t hesitate to throw that product away and replace it with a fresh batch.
Using hydrosols with kids
Caring for children and babies naturally becomes a lot less confusing if you have hydrosols to work with!
At Aromatics, we don’t usually recommend using essential oils for babies. Essential oils are simply too highly concentrated, and babies’ systems are very sensitive and responsive. It’s too easy for them to get overwhelmed. Hydrosols are a safer choice for babies’ delicate skin. Use a few sprays of German chamomile to comfort a baby’s skin during diaper rash, or put a bit of lavender artisan hydrosol on a cotton ball to dab tenderly at baby acne.
If you’re reluctant to diffuse essential oils around a baby, try using hydrosol in your diffuser instead of water. It makes the room smell amazing, and is gentle enough for a baby to breathe in.
For bigger kids, hydrosols come in handy for minor bumps, bruises, and scrapes they get while running around. If the skin is broken, be sure to wash the area with soap and water first… then spray it with helichrysum, calendula, or frankincense hydrosol.

What to look for in a quality hydrosol
Most producers treat hydrosols as a by-product of essential oil distillation. (Some even throw the hydrosol away.) This results in a lower quality hydrosol, because the distillation session isn’t allowed to continue for the right length of time to create a high-quality product.
At Aromatics, we distill our lavender specifically for hydrosol.
Our good friend Ann Harmon, one of the world’s foremost experts on hydrosols, taught us this natural art form.
One of our distillation sessions can go on for an entire afternoon as we patiently allow the plant to release all of its water-soluble therapeutic components.
Those hydrosols that we don’t personally distill, we get from close friends who follow Ann Harmon’s innovative process of distilling plants to craft the finest hydrosols in the world.
