To the Editor:—
In connection with a recent report of many cases of intestinal irritation from the use of karaya gum, I would say that I recently saw a patient who suddenly began to have three severe attacks of migraine in a week. When it was found that these attacks of headache started when she began to use a gummy laxative, this use was stopped and that was the end of the headaches.
