What Are Hydrosols?

If you have been following our blog, by now you know the process of steam distilling essential oils. Within our blog, you will find a lot of information on essential oils, their benefits, and ways to use them. However, aromatherapy isn’t just limited to essential oils. There are floral waters called hydrosols too.

So, what are hydrosols?

To extract essential oils out of the plant, a process called steam distillation is the most common way to accomplish this.  Large amounts of plant material are put into a vat and water is boiled underneath it. The tiny sacs of oil in the plant material pop open from the steam. The steam then goes through a cold pipe and separates the essential oil from the water (hydrosol). As they are not as potent as the oil, they are safer for animals, children, and even ingesting. Essential oils can be too concentrated for children, most animals, and ingesting. Hydrosols provide aromatherapeutic benefits with fewer safety concerns.

Hydrosol’s name is rooted in Latin; hydro meaning water while sol means solution. Hydrosols are called hydrolates, plant waters, and floral waters. The term late in hydrolate originated from the French word laite (milk); fresh hydrosol straight out of distillation often has a milky color until they settle. The plant material used for hydrosols and essential oils come from the roots, flowers, bark, resin, and even trunk of the plants. Hydrosols have unique aromas just like the oil but are far less potent making them safer for topical use, children, pets, and for diluting in water and drinking.

Hydrosol Quality

As with any product, especially essential oils, quality is important; therefore hydrosols should also be of the purest quality. Here are a few ways to distinguish the quality of a hydrosol.

  1. Knowing the distillation date of the hydrosol is a fine marker of quality. Hydrosols’ distillation dates are important because hydrosols have a much shorter shelf life than the oils.
  2. The term “flower water” is another marker of quality. Typically, at least from our encounters, most flower waters are not hydrosols.
  3. The ingredient label should only say hydrosol. For example, frankincense hydrosol. The ingredient name is Boswellia carteri (Frankincense) Water.
  4. Batch code numbers are another sign of quality. This allows the manufacturer or producer to trace that hydrosol back to its distillation date.

Storage and Shelf Life

Because hydrosols are aqueous, or water-based, they are much more susceptible to bacteria contamination and have a shorter shelf life.  A good rule of thumb is to use your hydrosols within a year of purchasing them. All of our hydrosols have a best by date on the label. I recommend storing your hydrosols in the fridge.  This will extend their shelf life to their full potential. If there’s a hydrosol you use every day, say as your face toner, it’s okay to keep it in the bathroom cabinet because you’ll use it up quickly. It’s also important not to introduce bacteria into them.  Keep opening the cap for times when you are going to add them to water to drink.  

Peppermint Hydrosol

Peppermint hydrosol is quite energizing and stimulating. Peppermint hydrosol can be drunk in the morning (diluted or undiluted) and gives you similar energy as a cup of coffee would. Peppermint is known for its digestive-supporting benefits and energy boosts. It calms and cool nerves while stimulating the brain. Peppermint hydrosol is anti-inflammatory and cooling. A digestive tract cleaner, peppermint hydrosol is supportive for all digestive issues including irritable bowel syndrome, heartburn acid reflux, and indigestion.
