Woad

woadIsatis tinctoria

In China a variety of woad root is treated to form Banlangen Keli, a popular herbal medicine claimed to remove toxic heat, treat sore throats and ameliorate a variety of diseases. In Britain it has a long tradition as a dye-plant but is thought too astringent for internal use, though it has been used externally as ointment or plaster.



The popular belief that Julius Caesar saw the Picts, or northern Britons, tattooed with woad, is based on a 17th Century mistranslation.
