Quick Answer
Yarrow remains effective when dried or ground, although its potency may decrease depending on the quality of drying and storage. Dried yarrow retains its medicinal properties for up to 6 months, but ground yarrow loses potency more quickly, requiring more frequent replacement.
Drying Techniques
Proper drying is crucial to preserve yarrow’s efficacy. Air-drying, either by tying the plants in small bunches or spreading them out in a warm, dry, dark place, helps maintain the integrity of its essential oils. To avoid mold and bacterial growth, drying should be completed within 2-3 days. Dried yarrow can be stored in airtight containers, like glass jars, to preserve its potency for up to 6 months.
Ground Yarrow Preparations
When using ground yarrow, it’s essential to note that its potency decreases rapidly, especially in moist environments. Ground yarrow can be stored for up to 1 month in airtight containers, but its effectiveness may be significantly reduced within 2 weeks. To maximize the shelf life and potency of ground yarrow, store it in the refrigerator or freeze it in airtight containers.
Preparing Yarrow Remedies
For herbal remedies, use dried or ground yarrow in the following proportions: 1-2 teaspoons of dried yarrow or 1/2 teaspoon of ground yarrow per 8 ounces of water. For poultices and salves, combine 2-3 tablespoons of dried yarrow with 1 tablespoon of plantain and 1 tablespoon of willow bark, mixing well to create a paste. Apply the paste directly to the affected area, securing it with a bandage if necessary.
