What is hydrosol?

Hydrosols are aromatic waters.

When aromatic plant materials are steam distilled, the water becomes infused with the plant’s water-soluble components. 

Here’s how the hydrosol distillation process works…

  1. The botanical material is loaded into a still along with pure water. (At Aromatics, we use pristine mountain well water). 
  2. Pressurized steam passes through the plant, breaking open its essential oil “sacs.” 
  3. As the steam passes through a cooling coil, it condenses back into a liquid—a combination of water and essential oil. 
  4. The essential oil naturally separates, floating to the top. 
  5. And the water is now hydrosol!

Hydrosols offer aromatherapists another way to work with therapeutic plants, which has gentler effects than essential oils, but with similar properties. Hydrosols, also referred to as floral waters, also contain carboxylic acids which have antioxidant and anti-inflammatory properties that can help to soothe and heal the skin. 

Hydrosols vs essential oils: 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. They 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 matter will often (but not always) have a different aroma. For example, myrrh hydrosol often smells different from myrrh essential oilLavender 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 of them can be applied to your skin undiluted, without concerns that they’ll cause irritation. Unlike essential oils, 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.

They 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.)

Some hydrosols also taste delicious, such as blood orange and peppermint. Adding a tablespoon or two to a glass of water makes a refreshing drink! *

*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

benefits and uses of hydrosol

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 as facial toners can help quiet your complexion and cool you down. 

Hydrosols are also excellent aromatherapy products 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 using them as skin care products or for 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
  • Calming facial toners
  • 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. These essential oil counterparts make the room smell amazing, and their fragrances are 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.

Kids love the taste of some hydrosols, too. A spoonful of peppermint hydrosol in a glass of water can help soothe their bellies, while a dash of elderflower can support immunity.

Hydrosol recipes

What to look for in a quality hydrosol

Most producers treat hydrosols as merely a by-product of essential oil distillation. (Some even throw the hydrosol away.) This results in a lower quality hydrosol with lowered effectiveness, because the distillation session isn’t allowed to continue for the right length of time to create a higher 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 hydro distillation sessions can go on for an entire afternoon as we patiently allow the plant to release all of its water-soluble therapeutic components into a floral water. 

Those hydrosols that we don’t personally distill, we get from close friends who follow Ann Harmon’s innovative process of distilling other plant material to craft the finest hydrosols in the world.
