I have stinging nettle in my yard and it is one of the best things you can put in your body! It is a cleansing agent for your liver, a blood tonic, very light taste, overall it is a wonderful thing to add to any tea. Once the needles are exposed to heat, they simply collapse and are no longer a threat. I cut young, tender shoots in the spring-wear gloves as they are nasty for hours after you touch them. Then I dry them on screens, or if I have gathered older leaves I string bundles and hang from the garage rafters-but this is an herb you don't want to bump up against so usually I just toss the leaves on a screen. Then when dry I crumple them up and use them like any other herbal tea. Not bad tasting at all, and with a little honey, a nice light beverage.
