Blue Flag has a wide application in the treatment of skin diseases, apparently aiding the skin by working through the liver, the main detoxifying organ of the body. It may be used in skin eruptions such as eczema and psoriasis; it is also valuable as part of a wider treatment program.

Blue Flag may be used with value where there is constipation associated with liver problems or biliousness. Blue Flag is a positive alternative for chronic, torbid conditions because it influences the glandular system, lymphatic, liver and gal ducts, and intestinal glands. It is also useful for treating hepatic congestion due to venous or lymphatic stasis.

Specific indications include chronic hepatitis and rheumatic conditions, scrophulous skin conditions, herpes, eczema, psoriasis, enlarged thyroid gland, and uterine fibroids. Blue Flag combines well with Echinacea, or Burdock and Yellow Dock.
