2. Stops Bleeding
In addition to helping to heal wounds and prevent them from becoming infected, yarrow can also be used to help slow and even stop bleeding. This can be particularly helpful when treating a person in a remote location, when it may take a long period of time for medical help to arrive.
Crushed yarrow root, when sprinkled onto an open wound, can help to slow and even stop bleeding altogether. Ancient civilizations would use yarrow root to stop an injured person from bleeding out until they could find more long-term solutions to stop the blood flow and seal the wound.
It is the presence of the chemical achilleine within the herb that makes it so effective in stopping bleeding, but the chemical makeup should only be one reason that yarrow is used, the centuries upon centuries of the application give us far more justification and evidence of its effectiveness.
