Also known as Dyer’s Bugloss, Alkanet’s roots yield a burgundy red to purple dye in an alkaline dye bath. Extracting first with alcohol enhances the color, and then add the extract solution to pre-mordanted wool or silk in a dye bath. Used since ancient times (300 BC!), it is also used for wood stains and food and makeup colorings.
