Materia Medica: Nettles
David Hoffman, an eminent medical herbalist, believes, "when in doubt, use nettle."
These spring greens get the spotlight as one of the most nutritious and safe herbal remedies on land. Nettle strengthens and support the whole body. It is one of the most widely applicable plants we have.
Nettles are used medicinally as a cleansing spring tonic and a nourishing vegetable if gathered when leaves are young. Some of its many medicinal uses include - gout, rheumatism, anemia, exhaustion, menstrual difficulties, skin problems, and hay fever.
It can also be cooked and eaten, brewed as a beer, infused as a teas or tincture. One cup of super-infused nettle leaf tea offers approximately 500 mg of bone-building calcium in a highly bioavailable form.
It was one of the most important plants used in the manufacture of cloth, and many judged nettle fabric to be finer then cotton or linen.
The ancient Greeks and Romans cultivated more acres of nettle than any other crop, and they used it extensively as food and medicine as well as in clothing
According to tradition, Caesar’s troops introduced the Roman Nettle into Britain because they flailed themselves with nettles to keep warm and treat arthritic or swollen joints, which was called urtication. The resulting nettle rash was reported to improve circulation to the area, relieving aches and pains.

Physical Description of the Plant: Stinging nettle is a common perennial herb to 8 feet found on moist forest edges, meadows and disturbed sites with rich soil. The dark green leaves are ovate and sharply toothed with a heart-shaped base and a pointy tip. They are located in opposite pairs and become progressively smaller toward the top of the stem. The leaves and stems are covered with tiny, hollow hairs tipped with silica. Nettle spreads by rhizomes, so each plant can have multiple stem and thus nettle typically grows in dense colonies. The tiny, inconspicuous green flowers droop in bunches from the leaf axils. Hollow hairs on the leaves and stems inject folic acid into the skin, causing a stinging sensation.
Habitat: It grows wild in the USA and Canada and is easily propagated from runners. Native to Europe and Asia.
Harvest and Collection: Aerial parts should be collected when the flowers are in bloom. Harvest the root in the Fall. Use gloves as the leaves sting.
