A nutritious, herbaceous perennial with a long history of medicinal use. Nettle leaves can be eaten like spinach or used to make a nutritious tea. We use our harvest every spring to make a large batch of Nettle Pesto - you can find that recipe on our blog. Fibres from nettle stems can also be used for spinning and weaving. Harvest young leaves, before the plants flower. Older leaves, and leaves after flowering, contain gritty particles called cystoliths, which may irritate the kidneys. We harvest young nettle leaves here in April. Trichomes (tiny hairs) on the plant's leaves and stems can cause skin irritation, hence the common name Stinging Nettle. It's advisable to wear gloves when handling. The stinging nature of the hairs is neutralized by heating briefly (cooking) or drying.
