Ever wondered about hydrosols? These gentle plant waters offer a softer alternative to essential oils and can be used for skincare, home care, and even pets. Let’s explore how they work and how you can use them!


Understanding Hydrosols

In aromatherapy, "less is more" philosophy emphasizes providing the body with gentle support without overwhelming it. Hydrosols, also known as hydrolats, perfectly embody this principle. These aromatic waters are produced during the steam distillation of plants that yield essential oils. Unlike essential oils, which are highly concentrated and require dilution for safe use, hydrosols are the gentle, water-based byproduct of this process. They retain the therapeutic properties of the plant in a milder form, making them safe and suitable for sensitive skin, including that of babies and animals.


It is important to distinguish hydrosols from floral waters. Floral waters are typically created by adding essential oils or fragrance oils to water, whereas hydrosols are therapeutic aromatic waters obtained directly from steam distillation.

Versatility of Hydrosols

Hydrosols bring a fragrant touch of nature to your daily life, offering a wonderful variety of uses that enhance both your skincare routine and household cleaning. In skincare, they shine as gentle toners, healing sprays for minor wounds, or ingredients in water-based cleansers and DIY bug-repellent sprays. For example, lavender or rose hydrosols can soothe overheated skin, while German chamomile or cornflower hydrosols offer relief for allergy-irritated eyes.


Beyond skincare, hydrosols can enhance your home environment. Use them as room sprays, linen mists, or even natural cleaning solutions. Their versatility and gentle nature make them a must-have in any natural wellness toolkit.

How to Make Your Own Hydrosols

Interested in creating your own hydrosols? You don’t need specialized equipment—just a few kitchen items will do. Here’s a simple method to get started:


What You’ll Need:

  • A large stockpot with a lid

  • Aromatic plant material (preferably fresh, but dried can work; about 2-3 cups)

  • Distilled water (enough to cover the plant material by about an inch)

  • A heat-safe dividing device (e.g., a bowl, stone, or steamer tray)

  • A heat-safe collection bowl

  • Optional: A bag of ice

  • Dark glass bottles for storage


Instructions:

  • Prepare the Pot: Place aromatic plant material (e.g., lavender, spearmint, or rosemary) in the bottom of the stockpot. Add distilled water until it covers the material by about an inch.

  • Set Up the Divider: Place your dividing device (e.g., a steamer tray or stone) on top of the plant material to create separation.

  • Position the Collection Bowl: Place a heat-safe bowl on the divider to collect the distilled hydrosol.

  • Add the Lid: Place the pot lid upside down so the handle directs condensed steam into the collection bowl.

A plastic bag of ice is placed on a lidded pot, viewed from above.  The bag of ice will promote condensation which will then be collected in the bowl.

  • Optional Ice: Add a bag of ice on top of the inverted lid to enhance condensation.

  • Heat the Pot: Gently heat the water on low to medium heat to create steam (avoid boiling to prevent scorching or pressure buildup). Steam for about 20-30 minutes, refreshing the ice as needed.

  • Cool and Collect: Turn off the heat and let the setup cool completely. Carefully remove the collection bowl and transfer the hydrosol to a dark glass bottle.

  • Store Properly: Label and date the bottle, then store it in the refrigerator. Use within 2-3 months for optimal freshness. Discard if the scent changes, the liquid becomes cloudy, or you notice any signs of spoilage.


A Personal Example

I recently made a spearmint hydrosol using this method with dried spearmint leaves. I’ve been using it on my dog, who has been suffering from allergies, evident from red, itchy patches on her stomach. After applying the spearmint hydrosol, her symptoms have significantly improved, and her licking has nearly stopped.


Final Thoughts

Hydrosols are a gentle, versatile, and natural way to incorporate the benefits of aromatic plants into your life. Whether you purchase them or craft your own, they offer endless possibilities for skincare, wellness, and home care. Experiment with different hydrosols and enjoy the delightful results of bringing nature into your daily routine!
