How To Store Herbs: 5 Ways To Make Them Last Longer

1. Store in airtight containers

Air, moisture, and light are the biggest enemies of dried herbs. To maintain their potency, store them in airtight glass jars or metal tins with tight-fitting lids. Avoid using plastic, as it can retain odours from other products or plants, this can compromise the quality of the herbs over time.

Always label your jars with the herb name and the date you purchased or dried them to keep track of freshness. Aim to replace dried herbs after 6–12 months for optimal effectiveness.

2. Control moisture

Even in airtight containers, dried herbs can be affected by humidity. Adding a silica gel packet or a small muslin bag filled with uncooked rice to your jars can absorb excess moisture and prevent mould growth. This is especially helpful in damp or humid climates. Often the silica gel packs come with supplements or other products so save them to use later!

3. Freeze fresh herbs

Some herbs, like peppermint, calendula, or nettle, are best used fresh but can be frozen to extend their shelf life. Here's how to store herbs by freezing them: rinse them, pat dry, chop finely, and spread them on a baking tray to freeze individually. Once frozen, transfer them to a sealed container or bag. Frozen herbs retain much of their medicinal properties and can be used in teas, poultices, or cooking.

4.  Transform your herbs into tinctures, oils, or vinegars

Fresh or dried herbs can be preserved by making tinctures, infused oils, or herbal vinegars. These preparations not only extend the life of your herbs but also concentrate their properties. Tinctures, made by steeping herbs in alcohol, can last for years when stored in dark glass bottles. Infused oils and vinegars are equally effective for preserving and can double as practical remedies for topical or internal use.

5.  Avoid heat, sunlight, and frequent opening

Heat and light degrade the active compounds in herbs, so always store them in a cool, dark place. Avoid placing them near stoves, windows, or other warm areas. For convenience, keep frequently used herbs in smaller containers and refill them from larger storage jars to reduce exposure to air and light.

Bonus tip: Regularly check your herbs

Part of knowing how to store herbs is knowing how to identify when they're past their use-by date. Inspect your stored herbs every few months for signs of degradation. Degradation can look like: faded colour, reduced aroma or mould growing on the plants. If a herb no longer smells like it used to and has developed a musty smell, it's best to replace it.
