DIGITALIS: A NEW USE FOR THE OLD VENERABLE HEART MEDICATION Morris Weiss, MD O nce upon a time in 1775, Mother Hutton, a little old lady in Shrop- shire on the left band of the languid Severn River and in the shadow of the stately ruins of Roman Wroxeter, had a secret family recipe for the cure of dropsy administered after the more regular physician had failed. William Withering, who was born in Shropshire, a young, hand- some and energetic physician to the General Hospital in Birming- ham, learned her (Mother Hutton's) tea contained 20 herbs. After arriving in his horse-drawn carriage and learning of the contents, this educated English gentleman physician and world renowned botanist felt Foxglove was the only herb in her concoction that was of medical value. Foxglove (Digitalis Purpura) is a ubiquitous English garden flowering plant. Withering made a preparation of the leaves and flowers and described the benefit of relieving dropsy (peripheral edema). His patients received various concentrations of his herbal tea. His classic monograph described the benefits and deleterious side effects, most commonly nausea and vomiting. To this day, 300 years later, his observations have no peer. He showed digitalis relieved edema in patients with large hearts but little to no effect in those with shrunken kidneys. He also describes slowing of the pulse in those with rapid irregular heartbeats (possibly atrial fibrillation) and all this with simply taking a history, bedside observation and using his fingers to examine the pulse. But why waste time on a bit of cardiology history most of this Journals’ readers memorized in sophomore pharmacology? MARCH 2017 11
