Christopher Hobbs:
“Yarrow tea is slightly bitter and aromatic and is a well-known European remedy used to ease the symptoms of colds, flu, and painful digestion, “liver stagnation” (weak bile flow) accompanied by poor fat digestion and a feeling of fullness after meals, especially fatty ones. Laboratory studies have established that yarrow has anti-inflammatory, antispasmodic (relaxing the smooth muscles found in the uterus and digestive tract), antifever, and antiviral effects. As an extra bonus, yarrow seems to have a calming effect, which can help with PMS and other nervous conditions, and it stops bleeding when applied to a wound.
Yarrow is a well-known diaphoretic herb which has long been used to reduce fevers and clear up congestive colds, flu, and other upper respiratory infections. It is also an excellent herb for cleansing programs, for which 2-3 dropperfuls of the tincture are added to hot water or cleansing teas and used in conjunction with saunas and sweating therapy.
There is a fair amount of variation in the chemistry and biological actions in wild yarrow populations, so we recommend growing your own from seed or from plants from a reliable source, rather than purchasing plants from nurseries or gathering them from wild populations.
Yarrow has a taste of BITTER, SALTY, AROMATIC and a temperature of COOL.”
Historical Uses
- Ancient Medicine: Yarrow has been used for centuries, dating back to Ancient Greece, where it was used for wound healing by soldiers (hence the genus name “Achillea” from Achilles). It was also used for fevers, digestive issues, and to stop bleeding.
- Traditional Practices: Native Americans, European herbalists, and Chinese medicine practitioners have utilized yarrow for various ailments, including as a remedy for menstrual problems, colds, and as an anti-inflammatory.
Modern Clinical Uses by Herbalists & Naturopaths
- Anti-inflammatory: Commonly used to reduce inflammation and treat skin conditions like eczema and psoriasis.
- Wound Healing: Applied topically for cuts, bruises, and to stop bleeding.
- Digestive Health: Used for gastrointestinal issues, including indigestion, bloating, and cramps.
- Circulatory Health: Promotes blood circulation and is used in cases of varicose veins.
- Women’s Health: Supports menstrual health, alleviating cramps and promoting regular cycles.
Chemistry & Pharmacology
- Active Compounds: Yarrow contains alkaloids (e.g., achilleine), flavonoids (e.g., quercetin), and essential oils (e.g., chamazulene, a potent anti-inflammatory). It also has tannins and coumarins that contribute to its therapeutic effects.
- Mechanism of Action: Known for anti-inflammatory, antimicrobial, and analgesic properties, largely attributed to its volatile oils and flavonoids. It has also been shown to stimulate blood circulation and support the immune system.
Clinical Trials
- Clinical Evidence: Several clinical studies suggest that yarrow may have moderate effectiveness in reducing inflammation and promoting wound healing. However, evidence for its use in other areas (e.g., digestive or menstrual health) is less conclusive.
- Wound Healing: Studies have shown that yarrow extracts can promote tissue regeneration and reduce wound healing time.
- Pain Relief: Preliminary trials suggest that yarrow may have mild analgesic effects for conditions like headaches or menstrual cramps.
In conclusion, yarrow has a long history of use in traditional medicine, and modern herbalists continue to use it for various conditions. Though its active compounds show promise in clinical trials, more research is needed to solidify its efficacy in mainstream medical applications. As with any herb, it’s essential to consider safety precautions and appropriate dosages.

Cautions
Common Side Effects: Generally safe, but can cause allergic reactions in some people (especially to ragweed, daisies, or chrysanthemums). It may also cause skin irritation when applied topically.
Contraindications: Should be avoided in pregnancy due to its potential to stimulate uterine contractions. It may also interact with blood-thinning medications or anticoagulants.
Precautions: People with allergies to plants in the Asteraceae family should avoid it. Overuse of the essential oil could lead to skin irritation or toxicity.
Occasional photosensitivity has been reported from eating the plant.
