woad

Woad is one of those plants which yield the deep blue colouring matter so greatly valued in the arts — Indigo.

To prevent this, it was enacted, that no wines of Gaſcony and Guienne, or woads of Tholouſe, should be imported into England, except in ships belonging to the King, or some of his ſubjects; and that all ſuch wines and woads imported in foreign bottoms ſhould be forfeited.
