What Hydrosols Are

When plant matter is steam distilled, both essential oils (oil-soluble constituents), and hydrosols (water-soluble constituents) are produced. Hydrosols contain all of the wa-ter-soluble chemical constituents of distilled plant matter.

Hydrosol comes from the Latin hydro, meaning “water,” and sol, which means “solution.” “Hydrosol” indicates any water-based solution, not specifically the type we are discussing here – but it is the word we will be using in this article.

Technically, “hydrolate” is the most accurate word to use. It comes from the Latin words hydro, meaning “water,” and lait, meaning “milk.” The “milky” reference reflects how it appears when it comes off the still. Hydrolate can also be spelled “hydrolat.”

Floral water is not a very accurate representation, as hydrosols can be steam distilled from more than just flowers.

Aromatic water is an acceptable way to describe a hydrolat, as they are full of aroma. They don’t always smell like their essential oil counterpart, however. Some smell better than others. If you find you don’t like the aroma of a hydrosol that you acquired for its therapeutic benefit, you can blend it with a more pleasant-smelling hydrosol, or make it into a lotion, adding essential oils that you do enjoy.

The Hydrosol Quick-Start Guide

How Hydrosols Are Made

Hydrosols are made during the steam distillation of plant matter that produces both es-sential oils and hydrosols.

Steam distillation has a simple, yet effective, design. A gentle fog-like steam enters through pipes with small vents located under a grate in the bottom of a large, tall pot containing plant matter. A tightly-fitting lid rests snugly on the pot, ensuring the steam makes its way into the tube leading to the condenser. The condenser contains coils, inside of which run cold water. This water cools down the steam, turning the steam back into water (hydro-lat), and oil (essential oil).

Many distillers use a Florentine flask for collecting the water and oil. This container is de-signed to efficiently separate the essential oil, which floats on the top, from the aromatic water underneath. One drain is located on the bottom of the container, allowing the over-flow of hydrosol to flow out during distillation. A second drain is located near the top, and is used to decant the essential oil after distillation is complete. Once complete, and the oil is drained and collected, the remaining waters are again drained from the bottom drain. The end result will produce many more times hydrosol than essential oil.

It can take an hour or longer to create a gallon of hydrosol, as best results are produced when slowly distilled under low pressure. This gallon will contain 0.2 – 0.8 milliliters of dissolved essential oil, which is not separated out due to its density..

The Difference Between Hydrosols and Essential Oils

Essential oils and hydrosols are both products of steam distillation, but their chemical makeup and uses are very different. It is known that there are safety considerations that must be respected when using essential oils. For example:

• there are dozens of essential oils that are unsafe for children

• there are dozens of essential oils that are unsafe for pregnant and/or nursing mothers

• there are several essential oils that are unsafe if you are on blood thinners

• all essential oils need dilution – some need more than normal dilution

• no essential oils should be ingested without guidance from a qualified health care provider

• essential oils can cause sensitization

• essential oils can be phototoxic

• essential oils are unsafe for use on pets

Hydrosols have very few safety issues. So few, I am going to list them all right here.

If you are pregnant, it is best to avoid consuming Cypress, Cornflower/Bachelor’s Button, Juniper Berry, Greenland Moss/Labrador Tea, Sweet Gale/Bog Myrtle, Rosemary, and Sage hydrosols.

If you have renal/kidney disease, it is best to avoid consuming Cypress, Juniper Berry, and Goldenrod.

If you have cancer, you will want to avoid consuming Bay Laurel/Bay Leaf.

For kids under age 2, it is recommended Sweet Gale/Bog Myrtle hydrosol be avoided (presumably internally only); for kids under age 6 it is recommended that Greenland Moss/Labrador Tea be diluted (doesn’t say how much) before use.

If you have a seizure disorder, it is recommended Greenland Moss/Labrador Tea be avoided.

Note: one sources prefers Peppermint be avoided on children under age three, but doesn’t cite any research. The same source suggests Eucalyptus be diluted when used topically and inter-nally for kids under age 4, but again doesn’t cite a reference. I personally feel this caution is not warranted, but the ultimate decision is yours to make.

When to Use Essential Oils, and When to Use Hydrosols

Both hydrosols and essential oils have their place. Here are some examples of when hydrosols are the best choice, and when essentials oils are preferred.

WHEN TO USE HYDROSOLS

Generally speaking, hydrosols should be considered first for the following:

• use on pets

• use on children

• undiluted topical use

• use on sensitive skin

• many topical skin issues

• consuming either as a water flavoring or for therapeutic use

• cuts and scrapes, linen sprays, perfumes, and as a base for making lotions

WHEN TO USE ESSENTIAL OILS

Essential oils are much stronger than hydrosols and can be used in other ways, such as:

• diffusing into the air

• more serious topical skin issues (diluted)

• killing germs and helping with colds

• cleaning solutions

• suppositories and ingestion for acute health conditions (always under supervi-sion from a qualified practitioner)

Shelf Life of Hydrosols

Many hydrosols have a shelf life of two years, but because they contain very little natural preservatives, some only last a year.

Expected Shelf Life of 16 Hydrosols (alphabetical order)

Hydrosol Name and Latin name Estimated Shelf Life

Balsam Fir Abies balsamea 16 months

Cedarwood Cedrus atlantica 14 months

Cinnamon Bark Cinnamomum zeylanicum 24 months

Cypress Cupressus sempervirens 14 months

Frankincense Boswellia carterii 18 months

Helichrysum Helichrysum italicum 24 months

Lavender Lavandula angustifolia 24 months

Neroli Citrus arurantium var. amara 24 months

Peppermint Mentha piperita 12 months

Roman Chamomile Chamaemelum nobile 24 months

Rose Geranium Pelargonium graveolens 16 months

Rosemary Rosmarinus officinalis 24 months

Sandalwood Santalum Album 24 months

Tea Tree Melaleuca alternifolia 16 months

Witch Hazel Hamamelis virginiana 12 months

Yarrow Achillea millefolium 24 months

Refrigerating your hydrosols can extend the shelf life. If you don’t have room in your food fridge, you can purchase a small dorm-sized refrigerator on amazon (I like this purple mini fridge!).

HOW TO TELL WHEN YOUR HYDROSOLS ARE GOING BAD

Beyond the visual signs of cloudiness or floating bits of growth in your bottle, you can also use pH strips to get a head’s up when your hydrosols are going bad.

Hydrosols have their own range of expected pH values which vary from 2.9 to 6.5 (es-sential oils have a pH of between 5.0 and 5.8). Test the hydrosols once when you receive them, and then again every three weeks. If you start to see the numbers drop, you know the hydrosol is starting to go bad.

Hydrosols for Home and Topical Use

There are so many ways to use hydrosols in your home and on your body. I am going to present some ideas, but I am sure you can come up with more ways to use hydrosols as you familiarize yourself with them. Here are a few ideas:

• linen sprays

• iron water

• makeup remover

• facial toner

• replace the water in your facial mask recipe with a hydrosol

• replace the water in your lotion recipe with a hydrosol

• use as perfume

• add to baths

Hydrosols for Internal Use

Hydrosols contain a higher concentration of volatile substances than herbal teas and are useful for therapeutic benefits when consumed. Some reasons you might want to con-sume hydrosols:

• to help soothe digestive issues such as cramping, diarrhea, constipation

• to help urinary tract infections

• to soothe arthritic pain from the inside

• to fight insomnia

• to eliminate a headache

• to calm nerves

• to eliminate cellulite

Hydrosols can be also used as food flavorings when added to water, juice, sauce, soups, salad dressings, cake mixes, yogurt, homemade ice cream, popsicles, and ice cubes.

The Hydrosol Quick-Start Guide

18

Dilution Guidelines for Hydrosols

Hydrosols do not require dilution before topical application. If you prefer to dilute for young children, you can, but it isn’t necessary, except perhaps in the case of Peppermint and Eucalyptus.

Dilution guidelines for internal use vary depending on the reason for use. It must be noted that diluting is more about taste and therapeutic use than safety. Hydrosols can be consumed with little dilution, but they are so effective, there is no reason to use a lot when less will do.

For basic daily maintenance, ingesting 1-3 teaspoons per day should be enough. Forth-erapeutic benefits, ingesting up to 3 tablespoons is suggested. Although you can’t “over-dose” on hydrosols, there is no need to use more than necessary. If you do feel compelled to consume more, listen to your body’s urges, and do so. This likely won’t last for more than a few days or weeks, and then you will probably find yourself backing off.

• Babies old enough to eat solids can ingest a 5% dilution – roughly 1/2 teaspoon in 1 cup water.

• Children up to age 10 can ingest a 10% dilution – roughly 1 teaspoon in 1 cup water.

• Children over age 10 can ingest a 25% dilution – roughly 3 teaspoons in 1 cup water
