Health Benefits & Sources
Why You Need It
- Reduces Inflammation: Helps calm internal and external inflammation.
- Stops Minor Bleeding: A classic astringent for cuts and scrapes.
- Soothes Digestion: Eases cramps, bloating, and gas.
- Promotes Relaxation: Helps lower stress and anxiety levels.
Deep Dive
Yarrow is a complex botanical containing over 100 active compounds, including flavonoids (like apigenin and luteolin) and sesquiterpene lactones. These compounds work synergistically. Its astringent quality comes from tannins, which tighten tissue and reduce secretions—this is why it stops bleeding and helps with diarrhea. The flavonoids act as powerful antioxidants, neutralizing cellular damage. Furthermore, Yarrow has been shown to relax smooth muscle tissue in the digestive tract, relieving spasms and cramping. It also contains a compound called achilleine, which directly aids in blood clotting. Finally, it interacts with GABA receptors in the brain, acting as a mild sedative to reduce anxiety without heavy side effects.
Natural Food Sources
Yarrow is an herb, not a fruit or vegetable. You won't find it in a grocery store produce aisle. It grows wild in temperate regions across the globe. You can forage it (with expert guidance) or buy dried yarrow from herbal suppliers to make tea or tinctures.
Supplementation
Dosage: There is no official FDA RDA for Yarrow. Typical herbal dosages are:
- Tea: 1-2 teaspoons of dried herb steeped in hot water, 2-3 times daily.
- Tincture: 2-4 ml (approx. 40-80 drops), 3 times daily.
Who Should Use It: It is ideal for those seeking natural relief for digestive upset, mild anxiety, or topical first aid for minor cuts. It is particularly popular among women for managing menstrual cramps.
