Blue Flag (Iris versicolor)

Blue Flag consists of the dried rhizome of Iris versicolor. It is primarily used in the treatment of skin diseases, and is thought to work in this area due to its effect on detoxification pathways in the liver. Herbalists often use it as part of a wider treatment for eczema and psoriasis. It’s primary actions are:

  • cholagogue
  • hepatic
  • alterative
  • laxative
  • diuretic
  • anti-inflammatory

Traditional usage

Kings American Dispensatory (1898) lists specific indications and usage for Blue Flag:

The specific indications for iris may be stated as fullness of thyroid gland; enlarged spleen; chronic hepatic complaints, with sharp, cutting pain, aggravated by motion; nausea and vomiting of sour liquids, or regurgitation of food, especially after eating rich pastry or fats; watery, burning bowel discharges; enlarged lymphatics, soft and yielding; rough, greasy conditions of the skin; disorders of sebaceous follicles; abnormal dermal pigmentation; menstrual wrongs, with thyroid fullness; unilateral facial neuralgia; muscular atrophy and other wastings of the tissues; bad blood.
