Scientific Summary
Nettle root and leaf (Urtica dioica) is a perennial herb whose dried roots and foliage are used medicinally. The herb is employed primarily as a diuretic and for relief of benign prostatic hyperplasia and rheumatic joint pain. Because it contains high levels of silicates, calcium, and potassium, it can irritate the skin when handled raw and may interact with blood‑thinning medications; it should be used cautiously during pregnancy and by people with kidney issues.
