Rating (out of 5): 2

Blue Flag (Iris versicolor) has been traditionally used in North American herbal medicine, especially by Native American tribes and 19th-century Eclectic physicians, to support the lymphatic system. Historical records indicate that Blue Flag root was considered a "blood purifier" and was employed for conditions thought to involve sluggish lymphatic drainage or glandular issues, such as swollen lymph nodes, skin eruptions, and certain chronic conditions. The rationale was based on the doctrine of cleansing or detoxifying the body, rather than on an understanding of the lymphatic system as recognized today.

Despite its historical use, there is scant modern scientific research substantiating Blue Flag's effects on the lymphatic system. Most available data relate to its historical applications and general uses as a mild laxative or for skin conditions. No clinical trials or robust pharmacological studies confirm its effectiveness or mechanisms for lymphatic support. The presence of potentially toxic constituents (such as iridin) has also limited contemporary use. Therefore, while Blue Flag's use for the lymphatic system is well-documented in herbal tradition, there is little to no scientific validation for its efficacy in this regard.
