I have one final word on stinging nettles: fresh is always better. After making my own tea and trying packaged tea, I can tell you that tea you brew yourself both tastes better and seems to have stronger effects. However, when I was out of fresh stinging nettle and desperate for allergy relief, I still found a good amount of help in the packaged tea. I just MUCH prefer the fresh tea. I think it's out of season now - so sad. I'll still keep my eye out for it.
Glad you're all sharing the little tidbits I share - that's what this is for!
