Yarrow tea, brewed from the medicinal herb Achillea millefolium, has a storied history that dates back thousands of years. Named after the Greek warrior Achilles, who is said to have used it to treat wounds on the battlefield, yarrow has gained a reputation for its potential therapeutic properties. With over 140 species characterised by clustered flowers and aromatic, hairy leaves, yarrow is more than just a decorative plant—it may hold promise for various health concerns.Promoting Wound HealingSince ancient Greece, yarrow has been used in poultices and ointments to accelerate wound healing. A 2019 study found that yarrow leaf extracts exhibited anti-inflammatory and antioxidant properties, potentially aiding in wound recovery. Additionally, a small 2017 study indicated that an ointment combining yarrow and St. John’s wort helped heal episiotomy sites, surgical cuts made during childbirth. Despite these promising findings, more extensive human studies are needed to confirm the effectiveness of yarrow in wound treatment.Supporting Digestive HealthYarrow has also been traditionally used to address digestive issues such as ulcers, bloating, and irritable bowel syndrome (IBS). The aerial parts of the plant are believed to contain bitter digestive compounds that support bile flow and function as a diuretic. Research has also suggested that yarrow’s alkaloids may possess gastroprotective and antioxidant properties, potentially improving overall digestive health. However, comprehensive clinical trials in humans are necessary to establish these effects definitively.Alleviating Symptoms of Depression and AnxietyYarrow tea may also have mood-enhancing effects. A 2016 literature review highlighted the potential of yarrow-derived alkaloids as natural antidepressants. The researchers suggested that these compounds could serve as a basis for antidepressant drug development. However, most studies included in the review focused on animal models, making it essential for future research to explore the impact of yarrow tea on mental health in human populations.Boosting Brain HealthPreliminary studies have also examined the impact of yarrow on brain health. A 2017 study suggested that yarrow extracts might help manage certain neurodegenerative disorders, including Alzheimer’s, Parkinson’s, and multiple sclerosis. Similarly, a 2018 review pointed to the alkaloids in yarrow as potential agents in reducing inflammation associated with brain and spinal cord conditions. While these findings are intriguing, they are primarily based on preclinical studies, underscoring the need for rigorous human research.Reducing InflammationChronic inflammation is associated with various health conditions, ranging from skin infections to liver diseases. Yarrow’s anti-inflammatory properties have been explored in multiple studies. A 2023 study conducted after the COVID-19 pandemic suggested that yarrow’s anti-inflammatory compounds might also help mitigate virus-induced inflammation. Nonetheless, further research is required to confirm these potential benefits.Addressing Insulin ResistanceEmerging evidence also suggests that yarrow may influence insulin sensitivity. A 2020 study observed that mice fed with yarrow extract for three months showed improved insulin responses. However, given the limited scope of the study and its focus on animal models, the implications for human health remain speculative.Yarrow tea, a traditional herbal remedy, has garnered attention for its potential health benefits, ranging from wound healing and digestive support to brain health and inflammation reduction. While early studies indicate promising effects, the majority of the research has been conducted on animals or in small-scale trials. As such, it is advisable to consult a healthcare professional before incorporating yarrow tea or its extracts into one’s diet, particularly for individuals with pre-existing health conditions or those taking medication.
