A leaf-only extract of *Urtica dioica* that removes the stinging hairs and fibrous material found in whole-leaf preparations. This form is valued for its milder gastrointestinal profile compared to crude nettle leaf, making it a common choice for those new to the plant or with sensitive digestion.
Traditionally used to support joint comfort and to promote healthy urine flow during minor seasonal discomfort. The extraction process concentrates water-soluble compounds such as flavonoids and caffeoylquinic acids, which are associated with antioxidant and anti-inflammatory activity in laboratory models.
Dosage varies by extract concentration and brand. The leaf extract is generally taken with food to minimise any residual stomach upset. As with all nettle forms, it may act as a mild diuretic.
