大靑 Daecheong (대청)
Daecheong is a plant that comes up in spring. The text describes a blue-purple stem, red-purple flowers, and a yellow root, with stem and leaf gathered in the third and fourth months and dried in shade. The name has attached itself to more than one plant over the centuries, so telling them apart has never been simple.
