Yarrow Flowers Powder

Also known as: Yarrow, Milfoil, Thousand-leaf, Achillea millefolium L.

Overview

Yarrow, scientifically known as Achillea millefolium, is a perennial herb indigenous to Europe and Asia. Its leaves and flowers are rich in essential oils, flavonoids, and phenolic compounds, which contribute to its medicinal properties. Traditionally, yarrow has been employed to address various health conditions, particularly wound healing, digestive issues, and menstrual disorders. Studies have focused on its potential antioxidant, anti-inflammatory, and antitumor effects, though high-quality evidence from systematic reviews and meta-analyses remains limited, specifically concerning its use as a dietary supplement. Current research indicates yarrow's involvement in protecting against oxidative stress and modulating hormonal balances, but clinical significance still requires further investigations, particularly involving human subjects.

Benefits

Yarrow shows potential therapeutic benefits particularly for women with polycystic ovary syndrome (PCOS), where it may improve reproductive parameters due to its antioxidant and antiandrogenic properties. Evidence points towards yarrow's efficacy in inhibiting lipid metabolism in colorectal cancer cells, suggesting antitumor activity. Additionally, there are indications that yarrow might enhance insulin sensitivity and aid in lowering cholesterol levels, although the strength of evidence remains moderate. The lack of adequately sized human trials limits the understanding of its clinical significance. Thus, while several animal-based studies illustrate promising outcomes, further research is essential to establish definitive benefits in human populations.

How it works

Yarrow's bioactive components, including flavonoids and phenolic acids, are believed to influence various biological pathways, particularly through interactions with estrogen receptors and modulation of lipid metabolism. These components exert antioxidant and anti-inflammatory effects, which may positively impact reproductive and metabolic systems. Additionally, molecular targets such as SREBF1 and FASN have been identified in yarrow extracts, indicating a specific engagement in lipid regulation pathways. However, comprehensive studies on the absorption and bioavailability in humans remain scarce.

Side effects

Yarrow is generally deemed safe for use, but data concerning its side effects in humans are not well-documented. Potential side effects may include allergic reactions and gastrointestinal discomfort, while severe adverse effects appear absent in the current literature. Caution is warranted for individuals on anticoagulant medications due to yarrow's antiplatelet activity, and its use is contraindicated during pregnancy and breastfeeding due to insufficient safety data. Additionally, those with bleeding disorders should exercise caution before using yarrow supplements, underscoring the need for further safety assessments in specific populations.

Dosage

Recommended dosage for yarrow has not been clearly established for humans, with animal studies suggesting effective doses ranging from 1.2 to 5 g/kg of body weight depending on specific effects. However, maximum safe doses have not been determined. Yarrow is typically consumed as a dried herb or extract, with its absorption potentially influenced by the method of extraction. No specific timing for administration has been established, reflecting the need for further investigation into optimal dosages and timing considerations for human use. Safety thresholds and upper limits remain undefined.

FAQs

Can I use yarrow safely?

While generally considered safe, yarrow should be used under medical supervision due to limited human study data and potential interactions with anticoagulants.

What are the common side effects of yarrow?

Common side effects may include allergic reactions or gastrointestinal upset, though detailed reports are scarce.

How should I take yarrow?

Yarrow can be used as a dried herb or extract; however, specific guidelines on timing and administration are not well established.

What benefits can I expect from yarrow?

Yarrow may offer reproductive health benefits and improve metabolic parameters, although results can vary based on individual conditions.

Is yarrow effective for PCOS?

Preliminary studies suggest yarrow may positively influence reproductive health in women with PCOS, yet more research is needed for conclusive evidence.
