Drying & Storing Medicinal Herbs Properly

Dried herbs only develop their full aroma and active compounds if harvesting, drying, and storage are done right.

The Right Time to Harvest

Just before or during flowering is when the active compound content is highest. Harvest in the morning after the dew has dried, but before the midday heat.

Drying Methods

Hang-drying – Hang small bundles upside down in a shady, airy spot. Ideal for rosemary, thyme, and lavender. No direct sunlight – it bleaches the color and destroys essential oils.

Rack/screen drying – For delicate herbs like lemon balm or mint. Max. 35 °C, good air circulation.

Dehydrator – Fast and controlled, especially handy for large quantities or humid weather.

Done When It Rustles

Well-dried herbs rustle to the touch and crumble easily. Stems that are still pliable mean: not done yet.

Storage

Dark, dry, and airtight – ideally in dark glass jars. Always label with the plant and harvest year. Quality declines after a year.
