Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Nettle (Urtica dioica), particularly in the form of teas or extracts, has a long-standing use in traditional herbal medicine for the treatment of skin conditions such as rashes and hives (urticaria). Folk medicine practices in Europe and Asia have used nettle for centuries to alleviate itching, redness, and swelling associated with various skin disorders. The plant contains bioactive compounds, including flavonoids, phenolic acids, and polysaccharides, which are believed to contribute to its anti-inflammatory and antihistamine effects.

Scientific studies investigating nettle’s efficacy for rashes and hives are limited, but some preliminary research supports its traditional use. In vitro and animal studies indicate that extracts of nettle can inhibit histamine receptors and reduce pro-inflammatory cytokines, offering a plausible mechanism for symptom relief in urticaria. A small randomized controlled trial published in 1990 ("Effect of Urtica dioica on histamine-induced urticaria," J Ethnopharmacol) showed that freeze-dried nettle reduced symptoms in people with allergic hives compared to placebo, but the study was limited by its small sample size.

Overall, while the scientific evidence is not robust, the traditional use of nettle for rashes and hives is well-established, and current pharmacological findings provide some support for its potential benefit. More rigorous clinical trials are needed to fully substantiate its effectiveness and safety in this context.
