Yarrow Flowering Top Extract
Also known as: Yarrow, Common Yarrow, Milfoil, Achillea millefolium
Overview
Yarrow, scientifically known as *Achillea millefolium* L., is a perennial herb native to Europe and Asia. It boasts fern-like leaves and small white or yellow flowers, and has been a part of traditional herbal medicine for centuries. Yarrow is primarily recognized for its potential benefits in wound healing, digestive health, and its antiseptic properties. Recent studies suggest that yarrow has antioxidant and anti-inflammatory properties, with compounds such as flavonoids, alkaloids, and essential oils contributing to its health effects. While preliminary research indicates potential anticancer effects as well, particularly against lipid metabolism in colorectal cancer cells, the overall scientific evidence in humans is still limited, necessitating further rigorous investigations into its safety and effectiveness.
Benefits
Yarrow offers several evidence-based benefits, chiefly its antioxidant and anti-inflammatory effects, supported by in vitro and some animal studies. The herb's high antioxidant capacity is linked to reductions in oxidative stress, which is beneficial for overall health. Additionally, yarrow may possess anticancer properties, particularly in inhibiting lipid metabolism in colorectal cancer cells. Populations seeking natural remedies for inflammation or oxidative stress may gain the most advantages from yarrow, although substantial studies focused directly on human subjects remain scarce. The variability in the quality of evidence raises uncertainties regarding the robustness of these claims and underscores the need for more clinical research to establish effect sizes and significance.
How it works
Yarrow’s health benefits are largely due to its antioxidant and anti-inflammatory actions. The plant actively scavenges free radicals, which diminishes oxidative stress and modulates several inflammatory pathways, impacting immune response and metabolism. Research demonstrates that it may inhibit critical lipid biomarkers like *SREBF1*, *FASN*, and *ABCA1*, which could alter lipid metabolism in cancerous cells. Although the absorption and bioavailability of its active ingredients are not thoroughly explored, it is theorized that they can be absorbed through the gastrointestinal tract.
Side effects
Yarrow is generally regarded as safe for most individuals when used properly; however, comprehensive safety data is lacking. Common side effects include allergic reactions and gastrointestinal disturbances, reported in over 5% of users. Less frequent adverse effects, such as skin irritation and photosensitivity, occur in approximately 1-5% of users. Rare side effects are poorly documented. Caution is advised for those on anticoagulant therapy due to the presence of coumarins, which may intensify bleeding risks. Pregnant and breastfeeding women are recommended to avoid yarrow due to insufficient safety data, and individuals allergic to plants in the Asteraceae family should exercise caution.
Dosage
There are currently no well-defined specific dosing guidelines for yarrow, with the minimum effective dose remaining unestablished and dosages varying widely. Yarrow is typically consumed in forms like herbal teas or capsules, with recommended amounts dependent on the product and preparation. No maximum safe dose is documented, and specific timing for intake is not recommended; following product labels is advised. Careful identification of the plant is essential to avoid confusion with similar species. Bioavailability may differ based on extraction methods, yet no co-factors have been established as necessary for its effectiveness.
