About

Andersonglossum virginianum, known as southern wild comfrey, is a flowering plant in the borage family native to North America. It is also sometimes called blue houndstongue.

Formerly placed in the genus Cynoglossum, it was transferred to the genus Andersonglossum in 2015.

Where it grows

Andersonglossum virginianum is native to the eastern United States. It densely populates the central and southeastern parts of the U.S. and is often found in open uplands, such as in southern New England, from New York to Illinois, Louisiana, Oklahoma, and from the south to Florida. A closely related species, Andersonglossum boreale, is disappearing from the southern part of its range in the United States.

Uses

Herbalists from the nineteenth-century suggested that A. virginianum could be a replacement or a substitute for Symphytum officinale (also known as comfrey). A. virginianum was traditionally used to help treat wounds and to flush out any internal digestive disorders and respiratory infections. It also acts as a sedative medication.
