Good stuff, the herbal Stinging Nettle. That's something I purposely grow in my yard. A friend of mine got me some starts of Urtica dioica, then later I grew more from seed...it's a nonnative species used for all kinds of things. There's native nettles in Texas, but one of them gives very bad stings! Urtica dioica is less stingy than that one. I put them in a part of my yard that's out of the way, then have a little sign for a warning. I could also put a little fence around it, but there's just the two of us living here and DH seldom goes in the yard...just doesn't seem necessary. As far as sting remedies, Jewelweed doesn't grow here...too hot, I guess...wish it would grow! Anyway, Urtica dioica does fine in shadier areas here as long as I water it from time to time. It really makes a great addition to my teas and really helps me sometimes when I'm not feeling good.
