Achillea Millefolium Var

Yarrow promotes wound healing through multiple mechanisms. Its tannins provide astringent effects that contract tissues and reduce bleeding, while flavonoids and azulene exert anti-inflammatory activity. The herb demonstrates antimicrobial properties against various bacteria, helping prevent wound infection. Achillicin contributes to styptic (blood-stopping) action. These combined effects make yarrow effective for minor cuts, abrasions, and superficial wounds when applied as a poultice or washed with cooled tea. Evidence level: C (preliminary clinical evidence and traditional use).

Yes, yarrow may interact with anticoagulant and antiplatelet medications. The herb contains compounds that affect blood clotting, potentially enhancing the effects of drugs like warfarin, aspirin, clopidogrel, or heparin. This interaction could increase bleeding risk significantly. Patients taking blood thinners should avoid yarrow or consult a healthcare provider before use. This contraindication is well-documented in herbal pharmacology references. Evidence level: C.

The standard adult dosage for yarrow tea is 4 grams of dried herb steeped in hot water, taken up to three times daily. This equals approximately 1-2 teaspoons of dried herb per cup. For wound healing, a cooled infusion can be applied externally as a compress or wash. Always start with lower doses to assess individual tolerance. Consult a qualified herbalist or healthcare provider for personalized dosing recommendations. Evidence level: Traditional use.

No, yarrow is considered unsafe during pregnancy. The herb has traditionally been used to stimulate menstrual flow and may cause uterine contractions, potentially leading to miscarriage. Animal studies suggest emmenagogue effects. Pregnant women, those attempting to conceive, and breastfeeding mothers should avoid yarrow in all forms, including teas, tinctures, and topical applications. This contraindication is well-established in herbal medicine practice. Evidence level: Traditional use and pharmacological evidence.

Pink yarrow (Achillea millefolium var. rosea) has been used in Celtic and Slavic folk medicine for wound healing, fever reduction, menstrual disorders, and digestive complaints. The herb's antimicrobial and anti-inflammatory properties make it valuable for treating minor wounds and skin conditions. Internally, it has been used to support digestion and regulate menstrual cycles. The pink-flowered variety shares similar medicinal properties with common white yarrow. Evidence level: C.
