Know Your Remedies: Iris versicolor (Iris.)

Common Names: Iris; harlequin blueflag; larger blueflag.

General Information

The symptoms of Iris versicolor (Iris.) mostly come from the gastrointestinal and nervous systems. The whole digestive tract may burn – anywhere from the mouth to the anus –  and can involve sour, acrid or burning vomit or stool. Right-sided headaches and migraines that are preceded by visual disturbances are also helped by this remedy.  Vomiting will not relieve the pain of the migraine and profuse urination may occur after the migraine or headache. The headaches may be triggered by sweets, and milk will worsen indigestion.

  • Headaches and migraines – especially on the right side.
  • Pain in the right temple or above or below the right eye.
  • Migraine with sour and acrid vomiting.
  • Visual disturbances and blurring before the headache.

  • Headaches or migraines that occur once a week, especially on weekends or Sunday.

Eye and Vision

  • Visual disturbances and blurring before a headache.

Gastrointestinal (Digestive) Problems

  • Burning through the length of the gastrointestinal tract – from mouth to the anus.
  • Sour, bilious and acrid vomiting, especially with a headache or migraine.
  • Vomiting with headache or migraine which doesn’t relieve the pain.
  • Profuse ropy saliva.
