Instead it refers to a plant that is indigenous to Europe and North America, including the area (probably North Carolina) where Doodle lives. A member of the Boraginaceae family, Cynoglossum officinale (also known as dog's tongue, houndstongue, houndstooth, and gypsy flower) is an herb with reddish-purplish blossoms that is believed to have some healing capabilities. In the past, it has been used to treat
- lung disease
