Synopsis

Source of validity: Traditional
Rating (out of 5): 1

The use of Iris (unspecified species, though often Iris versicolor or “blue flag”) for the treatment of boils is primarily based on traditional herbal medicine practices rather than scientific validation. In North American and European herbal traditions, Iris roots—particularly those of Iris versicolor—were historically used as a topical poultice or internal remedy for various skin conditions, including boils, abscesses, and other "impurities of the blood." Herbalists believed that Iris had "alterative" (blood-cleansing) and mild anti-inflammatory or detoxifying properties. The Eclectic medical movement of the 19th century in the United States is a notable source for these uses, where Iris was documented as a remedy for eruptions and glandular swellings. However, there is a lack of rigorous scientific research or clinical trials supporting the efficacy or safety of Iris for treating boils. The plant also contains toxic compounds and can cause irritation or poisoning if misused. Modern herbal medicine rarely employs Iris for skin infections today, and its use is largely of historical interest. Thus, the evidence for its effectiveness is weak (rated 1/5), based on anecdotal and traditional use without scientific corroboration.
