The plant that closes a wound.
Yarrow's oldest job is stopping blood, and the chemistry behind it is real.
- Styptic: crushed leaf packed onto a cut helps the blood clot and slows bleeding.
- Achilleine: the compound behind the clotting, studied as far back as the 1950s.
- Antiseptic: the aromatic oils help keep a fresh wound clean.
- Fever: a hot yarrow tea opens the pores and brings on a sweat, the old way of moving a fever through.
- Bitter: as a digestive bitter it stirs the appetite and the gut before a meal.
Most of yarrow's record is traditional. The wound-clotting part has the firmest ground under it.
