What is Yarrow?
Yarrow is the common name for the above-ground parts of the plant Achillea millefolium L., herba. Its scientific name, Achillea millefolium, comes from Greek mythology. In Greek mythology, Achilles was the strongest warrior and hero in the Greek army during the Trojan War. The genus name Achillea is in fact derived from the belief that Achilles, used this plant to treat the wounds of his comrades-in-arms. In Latin the Romans referred to it as “Militaris herba”, meaning official military herb. Its name in Irish was “Lus chosgadh na fola”, the plant that stops bleeding or “Lus na fola”, the blood weed. It is clear that the healing and medicinal benefits of yarrow have been coveted for thousands of years.

Evidence from studies
There are limited human clinical trials investigating the use of Yarrow in wounds but those that have been conducted have shown positive benefits without any undesirable effect 1,2. Oil based Yarrow extracts demonstrated significant anti-inflammatory effect in a study with 23 volunteers on artificially irritated skin2. Skin parameters assessed in the study; skin capacitance which relates to skin hydration levels, pH and erythema or irritation index were restored to the starting values after three- and seven-day treatment with the tested extracts, and the effects were proven not to be attributed to just the sunflower and olive oil vehicles themselves2. Another study used alcohol extracts of Yarrow which were incorporated into sterile Vaseline and applied to episiotomy wounds of 140 women following childbirth3. In the study it was observed that the Yarrow extract ointments were more effective in reducing redness, swelling and bruising of episiotomy wound (p<0.05) compared to the placebo which was Vaseline ointment alone3.
Animal studies have also found that Yarrow extracts have potential as wound healing agents. An ointment composed of both oil and alcohol extracts of Yarrow was seen to exert a wound healing effect on incision, excision, and thermal burn wounds in rats compared to the control or blank ointment in a study conducted in 20204. Additionally, a lipophilic extract of Yarrow was been tested for antimicrobial activity in a disk diffusion assay against 5 bacteria (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Salmonella enteritidis) and 2 fungi (Aspergillus niger and Candida albicans). The extract possessed a broad spectrum of antimicrobial activity against all tested strains5.
