Harvesting
Leaves can be harvested on their own, or the whole stalk can be taken. Nettles do sting, so it is suggested to use gloves.
Drying
Spread out in a thin layer on a sheet of paper (not a newspaper) or clean cotton fabric. Stalks can be tied in bouquets and hung. The plants should be dried in a well-aerated and shady place out of direct sunlight.
Use
Nettles strengthen the immune system and hematology: they are a good source of iron and other vitamins and minerals. Nettles help to normalize the menstrual cycle.
1-2 tablespoons of dried nettle leaves are submerged in a glass of boiling water. Allow to infuse for 15 minutes. Drink 1/3 of a glass three times per day.
Use with caution if you are prone to blood clots.
Nettle chips
Editor-in-chief of eng.lsm.lv, Mike Collier, also makes a healthy version of chips from nettles. "Grill the leaves for 5-10 seconds and snack away," says Mike.
