You can also make tea from it.
If a plant looks like a stinging nettle (Urtica dioica), but doesn’t sting, it’s probably the (rarer) fen or stingless nettle (Urtica dioica subsp. galeopsifolia - or a crossbreed, which can exhibit traits from both parents to varying degrees, e.g. have fewer stinging hairs. A safe id needs a microscope and chromosome count, though.
Wildflowerfinder.org.uk has useful photos comparing both.
