Therapy: This agent has not yet received much attention from the profession. Dr. Jennings, of Chicago, in October, 1896, published in the New York Medical Journal a letter containing the following statement:
"To this date I have successfully treated with crataegus one hundred and eighteen patients who were suffering with various forms of heart disease, not including fatty degeneration and tachycardia, and of the two latter forms of the disease. I have fourteen still under treatment.
Of one hundred and fifty-seven reports from other physicians using the drug in their practice, all but nine are commendatory and favorable, and of the nine, eight of them discontinued its use because the medicine made them sick at the stomach, and the ninth, a physician, said it gave him a fullness in the head. If these latter had reduced the dose to five or six drops it would have had full therapeutic effect, and would have obviated the nausea, and they, too, could then have reported favorably. ..."
