Synopsis

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

Blue Flag (Iris versicolor) has a history of use in traditional herbal medicine, particularly among Native American tribes and 19th-century North American herbalists. It was employed for a range of ailments, including as a remedy for nausea and vomiting, though more commonly for liver complaints, skin diseases, and as a purgative. The roots were sometimes decocted or infused to help "settle the stomach" or as part of formulas intended to treat nausea or induce vomiting, particularly in cases of perceived toxicity.

However, there is no substantial scientific evidence validating Blue Flag’s efficacy for nausea or vomiting. Modern phytochemical studies have focused primarily on its content of iridin and other glycosides, which are known to have strong purgative and potentially toxic effects rather than antiemetic actions. Most reputable herbal texts and clinical reviews do not recommend Blue Flag for nausea or vomiting due to its toxicity profile and lack of demonstrated benefit. The root is considered potentially hazardous, with side effects including gastrointestinal distress and possible poisoning.

In summary, Blue Flag’s use to support nausea and vomiting is justified only by sparse traditional references, and there is negligible modern clinical or pharmacological support for this application. Caution is strongly advised against its use for this purpose.
