- n. See bishop's-weed.
Sorry, no etymologies found.
Anyhow, this particular weed was held to be a specific for the bishop's evil; and, being introduced and cultivated for the purpose, it came to be known indifferently to herbalists as bishop-weed and gout-weed.
Nevertheless, it continues to grow all about our lanes and hedges, side by side with another quaintly-named plant, bishop-weed or gout-weed, whose very titles in themselves bear curious witness to its original uses in this isle of Britain.
