Sandi, I thought of you today when my leg started itching a while ago! Not from PI...hadn't been near any lately. But I do grow Stinging Nettle in the yard, and must have gotten careless while planting seeds today. Not that it's such a big deal...no rash, just itching for a while. I grow it well out of the way of where I usually go in the yard and mark it clearly. The plant makes such a great herbal for tea and a friend of mine got me started growing it. It really does seem to do me some good when I'm feeling a bit poorly and tastes great in tea.
