Background

Yarrow (Achillea millefolium) has a long history as an herbal remedy applied to the skin for wounds, cuts, and abrasions. The genus name Achillea is derived from the mythical Greek character, Achilles, who reportedly carried it with his army to treat battle wounds. Dried yarrow stalks are used as a randomizing agent in I Ching divination.

Currently, there are no high-quality trials available investigating yarrow. Although a laboratory study demonstrated yarrow's antibacterial effects, one poor-quality study using an herbal combination of yarrow, juniper, and nettle did not find any benefit on plaque or gingivitis inhibition.

Evidence

DISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Plaque/ gingivitis: Based on laboratory study, yarrow grass water extract showed antibacterial effects on Staphylococcus aureus. However, human study using a combination formula (including yarrow, juniper, and nettle) found no effect on gingivitis or plaque inhibition. Additional human study is needed in this area.
