Does Yarrow Help with Fever Reduction?

April 6, 2026

Quick Answer

Yarrow may help reduce fever due to its anti-inflammatory properties and ability to act as a diaphoretic, promoting sweating and relieving the body's temperature regulation imbalance.

Understanding Yarrow’s Properties

Yarrow (Achillea millefolium) is a common wild herb found in many regions, known for its medicinal and culinary uses. Its leaves, flowers, and roots contain compounds like sesquiterpene lactones, which exhibit anti-inflammatory and antipyretic effects. In traditional herbal medicine, yarrow is often used to treat fever, headache, and other conditions characterized by inflammation.

Using Yarrow for Fever Reduction

To use yarrow for fever reduction, identify the herb in the wild and harvest its leaves, flowers, or roots. Make a tea by steeping 1-2 teaspoons of dried yarrow in 1 cup of boiling water for 5-7 minutes. Drink 1-2 cups of yarrow tea 2-3 times a day to promote sweating and reduce fever. You can also combine yarrow with other fever-reducing herbs like plantain (Plantago major) or willow bark (Salix alba) to enhance its effects.

Precautions and Identification

When foraging for yarrow, be sure to correctly identify the plant, as it can be confused with other species like hawk’s beard (Crepis spp.) or salsify (Tragopogon spp.). Wear protective gloves and eyewear when harvesting yarrow, as its sap can cause skin irritation and eye irritation in some individuals. Use yarrow in moderation and under medical supervision if you have underlying health conditions or are taking medications.
