Modern Research on Urtica dioica in Integrative Medicine
🌿 Abstract
Stinging nettle (Urtica dioica) has emerged as one of the most scientifically investigated traditional medicinal herbs in modern integrative medicine. Historically used across Europe, Asia, and Indigenous healing systems for inflammatory disorders, urinary health, circulation, mineral nourishment, seasonal allergies, and vitality, stinging nettle now attracts growing attention in clinical and phytochemical research.
Modern scientific investigations increasingly explore nettle’s role in:
benign prostatic hyperplasia (BPH)
inflammatory modulation
allergic rhinitis
oxidative stress reduction
metabolic health
joint discomfort
immune signaling
mineral replenishment
