Yellow dock / Rumex crispus

A common weed and wayside plant, yellow dock has a deep taproot that draws up iron and other minerals from the soil, presenting them in an accessible form for absorption. The root is therefore prescribed in cases of iron-deficiency anemia, although its main use is for sluggish bowels and mild constipation.

Yarrow / Achillea millefolium

Used as something of a cure-all, yarrow is an excellent remedy for colds, flu, and fever. It is equally good for healing cuts and bruises and slowing or stopping bleeding, for example, nosebleed. The Ancient Greek hero Achilles reputedly used yarrow on his wounded troops during the Trojan War.
