There are two ways to do a nettle infusion:
1. Put about a few tablespoons of dried nettle in a jar (if making a cup just cover the bottom of the cup with dried nettles), cover with hot water and let steep for 20 minutes. Strain and enjoy. Optionally, you can add a little raw honey or coconut palm sugar for a little sweetness.
2. The second method is exactly the same as the first except that you add room temperature water (i.e. not boiling hot). If done this way, leave your infusion to steep overnight. This method is often used at night, and while the first method is ideal in the morning - strain and enjoy all day long.
