The stinging leaves are applied directly to the skin as a poultice (urtication) to alleviate rheumatic pain, arthritis, muscle aches, and sprains by stimulating circulation and reducing localized inflammation. Less commonly, some preparations are used internally as a diuretic, but this requires extreme caution due to potential toxicity.
