Common yarrow (Achillea millefolium) is at first glance an unassuming meadow plant that grows almost everywhere – in meadows, field margins, by roads and in gardens. Under the white or pinkish flowers and finely divided leaves, however, hides an herb with a long medicinal tradition. It was used by the ancient Greeks and Romans, herbalists in the Middle Ages and our grandmothers. And why? Yarrow has a wide range of effects that can support health in a natural and gentle way.
This article summarizes the verified effects of yarrow, safe ways to use it and traditional uses that have stood the test of time. The text is written to be useful for the reader while also corresponding to modern knowledge about herbs.
What does yarrow contain and why is it so effective?
Yarrow is rich in bioactive compounds, which make it one of the most valuable European medicinal plants:
- flavonoids – strong natural antioxidants that protect cells from damage,
- tannins – soothe mucous membranes and support healing,
- essential oils (for example chamazulene) – act anti-inflammatory and mildly antiseptic,
- bitter principles – support the production of digestive juices and better digestion,
- vitamin C and minerals – in smaller amounts strengthen immunity and overall vitality.
The combination of these substances makes yarrow a versatile herb that works for both external and internal complaints.
Proven effects of yarrow on health
1. Support for digestion and gallbladder function
Yarrow is one of the most commonly recommended herbs for digestive problems. It helps especially with:
- bloating,
- a feeling of heaviness after eating,
- mild irritation of the digestive tract,
- insufficient bile production.
The bitter compounds stimulate appetite and improve natural digestion, while the essential oils help calm an irritated stomach and intestines.
2. Anti-inflammatory and healing effects
Yarrow has a long tradition of use for minor injuries and skin problems. Traditionally it is used:
- to help stop minor bleeding,

In the past, fresh leaves were applied directly to the wound; today a decoction or yarrow ointment is more commonly used.
3. Support for immunity and defenses
Thanks to its antioxidants and essential oils, yarrow can contribute to strengthening the body’s natural resistance. It is often part of mixtures for colds and flu, where it:
