Stinging Nettle, burning weed, common nettle, all names for the same plant Urtica dioica. the stinging is not produced from an oil product like poison ivy, but instead is caused by barb like hairs on the plant surface, that do contain irritating chemicals (formic acid)
But it has been used for hundreds of years as a diuretic, to treat joint and muscle pain, hay fever and a plethora of other conditions. It is packed with Vitamins and minerals because the roots can grow to be quite extensive and deep, and as such can pull minerals from deep soil.
The stinging properties of the plant are removed if the plant is dried or cooked. I actually quite enjoy cooked nettles, they taste very similar to spinach.
supposidly when you pick the nettles, if you make sure to only grab the plant on the stem and move up you can crush the hairs and allow you to touch the plant. i have always used gloves however
i would think if you made a nettle tea, and then tested acid and added tannin to taste, then sugar to your level you could get a fairly decent wine. Sounds cool!
