We all know the nettle plant with its associated sharp sting. We do not all know how beneficial this plant is, especially as it is full of iron and other minerals it reaches deep down into the soil to bring into its leaves and stems. So it is a fine nutritional boost to drink nettle tea (unless you have a rare condition of too much iron in the blood called haemachromatosis).
It is a safe herb but traditionally would be used for 4-6 weeks with a break for 2-4 weeks.
