Yes, ground elder was known as Bishops Wort. It was brought here by the Romans, who used a tea made from the young shoots to ease the pain of, among other things, gout. Only Bishops could afford to eat well enough to get gout it was thought, hence Bishops Wort. it does make a good tea for anyone with pain from osteoarthritis, as it is mildly sedative and really does help with the aches after a good day weeding it out.
We cannot get rid of it as the garden backs onto an old quarry - where ground elder reigns supreme. it is quite satisfying to drink the tea, some slight revenge I suppose.
Ground elder tea: Take a good cupful of very young leaves, steep in boiling water for two or three minutes. Strain well, sweeten with a little honey if liked, drink warm just before bedtime. It tastes and smells a bit like cabbage water, but is not actually revolting, I think they were on to something there. Pity it became such a detested weed.
