Achillea millefolium var. borealis
Nordic variety of yarrow used by Vikings and Norse peoples as a wound herb, digestive bitter, and fever remedy.
Norse Yarrow (Achillea millefolium var. borealis) is a Nordic variety of yarrow traditionally used by Vikings as a wound herb, bitter tonic, and fever remedy. Modern research supports its hemostatic, anti-inflammatory, and bitter tonic properties, attributed to active compounds such as achillin, azulene, camphor, and flavonoids. It is commonly administered as a tea (2-4 g dried herb) or tincture (3-5 mL).
The hemostatic effect is primarily due to achillin, which promotes platelet aggregation and vasoconstriction via activation of thromboxane A2 receptors. Azulene and flavonoids (e.g., apigenin, luteolin) inhibit cyclooxygenase-2 (COX-2) and lipoxygenase (LOX) pathways, reducing prostaglandin and leukotriene synthesis, thereby exerting anti-inflammatory activity. The bitter tonic effect is mediated by camphor and sesquiterpene lactones, which stimulate bitter taste receptors (TAS2Rs) on the tongue, triggering vagal reflexes that increase gastric acid secretion and digestive enzyme release. Additionally, flavonoids modulate GABA-A receptors, contributing to mild anxiolytic and sedative effects.
