What is the best way to store dried herbs for freshness and longevity?
In general, you’ll want to store dried herbs and other medicinal preparations in airtight glass jars inside a cabinet, on a dark shelf, or anywhere out of direct sunlight. A location that is cool and dry will further increase the shelf life of your remedies. Keep your medicines out of the reach of small children and always label each bottle, as it’s all too easy to forget the contents of an unmarked medicine over time!
Dried leaves and flowers will typically last one to two years, and roots can last two to three years.
If you store dried herbs correctly, you’ll find the following to be a useful guideline:
- Dried leaves and flowers have a shelf life of 1-2 years
- Roots, seeds, and barks can last 2-3 years
Use your senses—smell, sight, and taste—to determine the vitality of stored herbs. If an herb looks vibrant and has retained most of its flavor and/or aroma, it’s still good medicine!
Label your jars of dried herbs with the name of the plant, the part gathered, and the date they were stored.
Where can I find high-quality dried herbs?
To source the most vibrant herbs, look first to small herb farmers and medicine makers (and even some top-notch larger suppliers). When purchasing herbs, we recommend sourcing them in this order when possible:
Local Growers and Small Sellers. This is an opportunity to visit local herb farms and see their medicine for yourself (plus you’ll be supporting small businesses and your local economy). Some growers even offer you-pick herbs. To find sources near you, see Rosalee de la Forêt’s List of Sustainable Herb Farms and Ethical Wildcrafters and our List of Bulk Herb Suppliers.
Local Medicine Makers. Check with your local apothecaries and medicine makers for freshly stocked bulk herbs and tea blends. Feel free to inquire where they source their herbs!
Mail-Order and Online Sellers. This is a straightforward option for purchasing bulk dried herbs online or by catalog. Check out our Sources of Bulk Herbs and Medicine Making Supplies list.
Dry Your Own Herbs. For a tutorial on drying fresh herbs from your garden, check out Mountain Rose Herbs’ article on How to Harvest, Dry, & Store Herbs from the Garden.
Storing freshly made tincture in an amber glass bottle will extend the medicine’s shelf life.
How do I store tinctures and other herbal preparations? And how long do tinctures last?
Like dried herbs, other herbal remedies will benefit from storage in a cool, dark space—a cabinet, hutch, pantry, wooden pie safe, or the like. Below you’ll find nuanced storage details and shelf life expectancies for:
To prevent ink from running due to dribbles from the bottle, place clear packing tape over your labels.
Storing Herbal Tinctures
Properly stored tinctures—prepared with high-percentage alcohol (50% or higher)—can last for years, even decades. We store our tinctures (and syrups, vinegars, oxymels, infused oils, and simple syrups) in amber glass dispensing bottles with polyseal caps. These bottles have several helpful attributes:
- The brown glass excludes light, which can degrade medicine over time.
- The inside of the polyseal cap is resistant to solvents, as it is manufactured for chemical storage. While I don’t like that the inside of the cap is plastic, I haven’t yet found a better system.
- The bottles are a small investment, but they are washable and reusable—I have dozens that have been with me for over a decade.
As an alternative, people often store their medicine in glass canning jars. If you go this route, be aware that alcohol and vinegar will corrode canning lids over time, contaminating the medicine with plastic compounds. To prevent this, use natural waxed paper as a barrier on the inside of the lid.
Finally, make sure to store your alcohol-based tinctures some distance from the stove and potential kitchen fires as they are very flammable.
To protect your medicine from potential contamination due to corroded canning lids, place a layer of natural waxed paper on the inside of the lid while your herbs are infusing in vinegar.
Storing Herbal Vinegars
Vinegar-based extracts have a shorter shelf life than alcohol-based tinctures and should generally be used within six months to one year when prepared with fresh herbs (and ideally refrigerated), and one to five years for vinegars prepared with dried herbs. As with alcohol tinctures, we prefer to store vinegar extracts in amber glass bottles with polyseal caps.
Storing Herbal-Infused Honeys
Herbal honeys made from dried herbs have a very long shelf life—decades to perhaps centuries, or even millennia! We store infused honeys in glass jars of varying shapes and sizes. If you prepare honey from fresh herbs, the water weight will dilute the honey and its shelf life will be much shorter. We recommend refrigerating herbal honeys made from fresh herbs. Some of our favorite honeys to infuse include:
- Hawthorn, berries (Crataegus spp.)
- Angelica, root (Angelica archangelica and other Angelica species)
- Elecampane, root (Inula helenium)
- Elderberry, fruit (Sambucus nigra var. canadensis and Sambucus nigra)
- Schisandra, berries (Schisandra chinensis)
Elderberry-infused honey is a delicious stand-alone remedy, or it can be transformed into a medicinal herbal syrup.
Storing Herbal-Infused Oils and Salves
Herbal-infused oils and salves will typically last two to three years when refrigerated and one year unrefrigerated, depending on the stability of the oil used. Using dried herbs will greatly increase the shelf life of your herbal-infused oils.
Storing Powdered Herbs and Capsules
Herbal powders have a shorter shelf life than cut and sifted herbs (loose teas and bulk herbs) because the plant material is ground to such a fine consistency. Use powdered herbs within 6-12 months, storing them in the refrigerator or freezer for maximum freshness.
