Brinjasif, commonly known as Yarrow (Achillea millefolium), is a hardy plant found across temperate regions of Europe, Asia, and North America. It typically grows upright, with finely divided, feathery leaves and flat-topped clusters of tiny, white flowers. Often seen along meadows and roadsides, Yarrow has played a role in various traditional folk practices throughout history. Its natural composition includes several plant compounds, notably tannins, which contribute to its distinctive character in herbal blends.
