The stinging hairs do disappear once it is dried or steamed.
As a diuretic tea though, it is invaluable. High in iron that the body can easily absorb, it stimulates circulation and helps clear uric acid.
The plant has a creeping rhizome that can establish itself quite permanently in the garden so it is best planted where it will not be brushed past often.
It is best planted in groups of plants to enable the fertilisation of the summer flowers. Thus ensuring a constant supply.
Combined with Comfrey leaves, it helps to make a fantastic compost tea that helps with mildews and fungus.
