How is yarrow prepared for medicinal uses?

Preparing yarrow (Achillea millefolium) for medicinal uses involves several steps to ensure proper harvesting, drying, and storage. Here's how yarrow is typically prepared for traditional and herbal medicine:

1. Harvesting:

- Yarrow is harvested during the blooming season, usually from mid-summer to fall (around June to September in temperate regions).

- Gather both the flowers and leaves when they are fully open and before the seeds start to disperse.

- Cut the yarrow plant just above the base, leaving the taproot undisturbed for future growth.

2. Cleaning:

- Gently shake the harvested yarrow to remove any loose dirt or debris.

- Rinse the yarrow in cool, running water to remove any remaining impurities.

3. Drying:

- Bunch the yarrow together and hang upside down in a warm, well-ventilated space, such as a shed, barn, or attic.

- Alternatively, spread the yarrow in thin layers on drying racks or screens, ensuring airflow throughout.

- Avoid direct sunlight as it can degrade the active constituents in yarrow.

4. Storage:

- Once completely dry, yarrow can be stored in airtight glass jars or opaque containers to protect it from light and moisture.

- Ensure the containers are labeled with the name of the herb and the harvest date.

- Store in a cool, dry place away from direct sunlight.

Remember, it's always recommended to consult a qualified herbalist or healthcare professional before using yarrow or any other medicinal plant for therapeutic purposes. The dosages and preparations can vary depending on the intended use and individual circumstances.
