Yarrow

A useful traditional first-aid and fever-support herb, but one with limited modern trial data.

A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.

Yarrow has hemostatic, anti-inflammatory, and bitter-aromatic properties in traditional practice. Most evidence is historical or preclinical rather than modern randomized trials.

• Used traditionally for minor wound support
• Fits old-school fever-and-sweating tea formulas
• Provides bitter-aromatic digestive action

Usually used as tea, tincture, or topical wash according to traditional practice.

• Allergic reactions
• GI upset
• Skin irritation

May trigger allergy in ragweed-sensitive individuals and should be avoided during pregnancy.

Traditional use is long, but modern randomized evidence is thinner than the reputation suggests.
