A plant with reddish flowers or stems, or any plant associated with blood in traditional herbal knowledge.
Compound of 'blood' and 'weed,' referring to plants with red coloring or traditionally used to treat bleeding in folk medicine. Common names like this date back to medieval herbalism when plant appearance determined medicinal use.
Plants were named by what they looked like before we had microscopes—the 'Doctrine of Signatures' claimed red plants healed the blood, resulting in dozens of blood-named plants like bloodroot and bloodwort. Modern medicine proved this wrong, but the names survive.
