About Yarrow

Yarrow (Achillea millefolium) is a herb used in the Western Herbalism and Mediterranean traditions to help with Fever, Wound Healing, High Blood Pressure, and Inflammation, among 3 other conditions it addresses. The aerial parts are the part traditionally used, used both internally and topically.

Botanical background

Achillea millefolium, commonly known as yarrow /ˈjæroʊ/ or common yarrow, is a flowering plant in the family Asteraceae. It is native to temperate regions of the Northern Hemisphere in Asia, Europe, and North America. It has been introduced as a feed for livestock in places like New Zealand and Australia. However, it is a weed in those places and sometimes also in its native regions.

Quality tips

When buying Yarrow, look for: certified organic labelling, clearly stated country of origin, third-party lab testing for heavy metals and pesticides, and a batch expiry date. Standardised extracts offer consistent dosing; bulk dried herbs are more economical for regular use. Avoid very cheap, unlabelled products — quality varies enormously.
