1. Botanical Overview of Yarrow
Yarrow is a perennial herbaceous plant that can reach heights of 30 to 60 cm. It is distinguished by its upright stems covered with fine hairs and its leaves divided into narrow segments, which give it the characteristic “thousand-leaf” look. Its small white, pink, or sometimes yellow flowers cluster in flat-topped corymbs, typically blooming from June to September.
This plant thrives in meadows, roadside areas, and wastelands, preferring well-drained and sunny soil. It is easy to identify and is among the most commonly used wild plants in European herbal medicine.
2. History and Traditional Uses
Since antiquity, yarrow has been famed for its medicinal properties. Its name derives from Achilles, the Greek hero who reportedly used this plant to treat the wounds of his soldiers during the Trojan War.
In the Middle Ages, it was commonly used to stop hemorrhages, reduce inflammation, and treat digestive disorders. Herbalists and healers also employed it to relieve cramps, promote wound healing, and as a general tonic. Yarrow remains a staple in traditional European medicine due to its versatile benefits.
3. Chemical Composition and Active Compounds
The therapeutic efficacy of yarrow comes from its rich and complex composition:
- Essential oils: camphor, thujone, eucalyptol, which provide antiseptic, anti-inflammatory, and antispasmodic properties.
- Flavonoids: apigenin, luteolin, which act as powerful antioxidants.
- Tannins: astringent compounds that help contract tissues and promote healing.
- Alkaloids: substances affecting the nervous and muscular systems.
- Phenolic acids and coumarins, contributing to anti-inflammatory effects.
- Vitamin K, essential for blood coagulation.
This unique combination explains the plant’s versatility and effectiveness.

Anti-inflammatory Action
Flavonoids and essential oils work synergistically to reduce both local and systemic inflammation. This property is useful for relieving joint pain, rheumatism, and skin inflammations.
Hemostatic Properties
Yarrow is particularly well-known for its ability to stop bleeding, whether external (cuts, wounds) or internal (heavy menstrual bleeding). Tannins help tighten blood vessels, while vitamin K plays a key role in coagulation.
