The short answer: keep dried herbs in clean, dry, airtight containers in a cool, dark place; label every container; and store all of them where children cannot reach. The checklist below turns those habits into steps you can follow at home.
This guide is general education about household storage. It is not medical advice, and it does not tell you whether any herb is right for you. The storage sources we cite are university Extension guides written about drying and storing herbs for kitchen use, so they speak to flavor, quality and mold risk, not to the strength or safety of herbal products taken for health. For packaged products, follow the storage directions printed on the label.
Quick Storage Checklist
Moisture
- Make sure herbs are fully dry before they go into a jar. Alabama Cooperative Extension suggests placing them in tightly sealed jars in a warm place for about one week and checking the jars regularly for moisture.
- If moisture appears on the inside of the glass or under the lid, take the herbs out and dry them further. The same Extension guide says that otherwise there is a chance of mold growth.
- Choose dark glass jars or tins. The Extension guide advises against cardboard or paper containers because they absorb oils and leave dried herbs tasteless.
- Keep jars away from the stove, dishwasher and sink, where heat and steam build up. This placement tip is our own editorial suggestion, not a point taken from the sources below.
Mix-ups
None of the sources we reviewed address label or mix-up practices, so the steps below are editorial suggestions rather than cited requirements.
- Label each container with the plant's common name and, if you know it, its botanical name. Add the date you stored it.
- Keep one herb per container. A blend of leftovers cannot be identified later.
- If a jar loses its label, or you cannot say with certainty what is inside, do not guess. Discard it.
- Store herbs apart from spices, cleaning products and medicines so one is less likely to be mistaken for another.
Children
- Store herbs and supplements out of children's sight and reach, for example in a high cabinet or a closed box. This is our editorial suggestion.
- Do not count on the packaging to protect children. The National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health, says that child-resistant packaging is not required for dietary supplements, and that about 4,600 children go to the emergency room every year because of dietary supplements, most of whom took a vitamin or mineral while unsupervised.
- If a child may have swallowed something, call Poison Help at 1-800-222-1222. According to the Health Resources and Services Administration, the call is free and confidential, and the line operates around the clock.
Why Cool, Dark and Dry Matter
Oregon State University Extension recommends placing dried herbs in an airtight container and storing them in a cool, dark, dry location for the best flavor and color. Alabama Cooperative Extension adds that heat affects quality, and that dried food keeps longer when it is kept cool.
Both guides also favor storing leaves and seeds whole. Oregon State says crushing or grinding herbs and seeds for storage increases the loss of aroma and flavor, and that whole seeds and leaves have the longest shelf life. The practical habit is to keep leaves whole and crush them just before use.
How Long Do Dried Herbs Last?
For kitchen herbs, Oregon State Extension says that for best flavor you should use them within six months to one year, and that airtight containers can also go in the freezer. Those figures are about flavor. We did not find a source that sets a safe-to-use date for herbs taken for health purposes, so we will not give you one. A date printed on a product label, or advice from a pharmacist, is a better guide than a rule of thumb.
When to Throw Herbs Out
The Alabama Extension guide connects trapped moisture with the chance of mold growth. Beyond that point, the following is our editorial judgment, not a statement from the sources: if you see damp patches, clumping, or anything that looks like mold, or if you cannot identify what is in a jar, discard the contents and wash the container well before reusing it. Please do not try to rescue herbs that may be moldy by re-drying them.
Who Should Ask a Professional First
Storage is only one part of using herbs safely. As a general caution, if you are pregnant or nursing, have a medical condition, take prescription or over-the-counter medicines, or are thinking about giving any herb to a child, talk with a pharmacist or your healthcare provider before using it. It also helps to keep a written list of everything you take. Our guide on preparing a safer pharmacist conversation with an herb and medicine list walks through how to do that.
What to Do Next
- Pull out every jar, bag and tin of dried herbs you own.
- Discard anything unlabeled, damp, clumped or moldy.
- Label and date what remains, one herb per container.
- Move the containers to a cool, dark, dry cabinet that children cannot reach.
- Save the Poison Help number, 1-800-222-1222, in your phone.
