Laportea canadensis
North American woodland nettle; used by many Indigenous peoples as nutritive food and medicine for pain and arthritis via urtication.
Wood Nettle (Laportea canadensis) is a North American herb traditionally used by Indigenous peoples for arthritis pain relief via urtication and as a nutritive spring vegetable. Its active compounds include formic acid, histamine, quercetin, and rutin, which contribute to anti-inflammatory and analgesic effects. Modern evidence supports its use in urtication therapy for osteoarthritis and as a nutrient-dense green.
Urtication with fresh leaves delivers formic acid and histamine, causing a localized inflammatory response that may stimulate blood flow and activate counter-irritation pathways to modulate pain. Flavonoids such as quercetin and rutin inhibit cyclooxygenase (COX) and lipoxygenase (LOX) enzymes, reducing prostaglandin and leukotriene synthesis. The high iron content supports its traditional use as a nutritive tonic, potentially improving iron status.
