Nettle
A remineralising herb traditionally used to support mineral balance.
Nettle (Urtica dioica, Urtica urens) is a widespread herb recognised for its stinging hairs and nutrient-rich leaves and roots. Containing minerals and trace elements (including iron and calcium), vitamins, flavonoids and other phytochemicals, it is traditionally valued for remineralising properties and used as a mild diuretic and depurative in herbal practice.
Employed since antiquity for issues such as fatigue associated with mineral deficiency, rheumatic and urinary complaints, digestive irregularity and some skin conditions, nettle’s effects vary between individuals and cannot be guaranteed. Common formats include infusions, dried powders, standardized extracts and tinctures; pregnant or breastfeeding people and children should exercise caution, and fresh plant material can irritate eyes and mucous membranes.

Origin & History
Nettle belongs to the Urticaceae family and the genus Urtica, with more than twenty species distributed across temperate regions worldwide. The best-known species, Urtica dioica (a perennial) and Urtica urens (an annual), favour fertile, nitrogen-rich soils and are commonly found in fields, gardens, meadows and woodland margins; leaves and roots are typically harvested in spring and summer for culinary or herbal use.
Used since antiquity in Europe and beyond, nettle appears in the writings of classical authors and in medieval herbals and has long featured both as a food (soups, stews and salads) and as a medicinal plant in traditional systems. Ancient physicians such as Dioscorides and Hippocrates mentioned nettle in medical writings, and it remained a recognised remedy through the Middle Ages into more recent herbal traditions. In many cultures nettle’s practical uses extended to fiber and animal feed, and contemporary interest reflects both its nutritional composition and its historical role in folk medicine.
Composition & Active Compounds
Nettle is a tall herb with a square stem and opposite, toothed leaves covered in stinging hairs; Urtica dioica typically produces creeping roots while Urtica urens has a taproot. The plant’s leaves and roots contain a nutrient-dense mix of minerals and trace elements, vitamins, essential amino acids and a range of phytochemicals including flavonoids, tannins, phytosterols, chlorophyll and biogenic amines in the irritant sap.
Leaves and roots are the parts most commonly used in supplements.
