ESSENTIALS
The main pathologies that you will be called upon to treat with this remedy are cases that combine problems of the gastrointestinal tract, whether diarrhoea or constipation, coupled with one sided headaches or migraines. These migraines are usually affecting the eyesight, by blurring the vision, most of the times at the beginning of their onset. The patient knows that a severe headache is coming when they start to have the blurring in their vision. As the headache progresses, the blurring becomes more but at a certain point the blurring is clearing and nausea starts which may end up in vomiting.
An interesting keynote of such migraines is that the vision is blurred on the side where the migraine is. The Iris headache is often de- scribed as being a right – sided headache but in my experience the pain can also be at one time situated on the left side affecting only the left eye and next time on the right side affecting the right eye.
Another keynote is that the vomiting comes in the first hours of the migraine and not at the peak of the crisis, as is usually the case with Sanguinaria. Both these remedies get periodical headaches every 7 or 8 days and both have vomiting, but the main difference is the location of the pain and the time of vomiting. In Iris the pain is frontal and the vision is affected in the commencement or even before the actual migraine starts. In Sanguinaria the migraine starts from the right occipital protuberance and extends to the right eye. In Iris the vomiting, which is bilious, extremely sourish or sweetish, comes early in the beginning of the headache and does not ameliorate. In Sanguinaria it comes in the end of the crisis when
