Dr. Melanie Lipinska, in her "Histoire des Femmes Medecins," a thesis presented for the doctorate in medicine at the University of Paris in 1900, subsequently awarded a special prize by the French Academy, reviews Hildegarde's work critically from the medical standpoint. She says that the saint distinguishes a double mode of action of different substances, one chemical, the other physical, or what we would very probably call magnetic. She discusses all the ailments of the various organs, the brain, the eyes, the teeth, the heart, the spleen, the stomach, the liver. She has special chapters on redness and paleness of the face, on asthma, on cough, on fetid breath, on bilious indigestion, on gout. Besides, she has other chapters on nervous affections, on icterus, on fevers, on intestinal worms, on infections due to swamp exhalations, on dysentery, and a number of forms of pulmonary diseases. Nearly all of our methods of diagnosis are to be found, hinted at at least, in her book. She discusses the redness of the blood as a sign of health, the characteristics of various excrementitious material as signs of disease, the degrees of fever, and the changes in the pulse. Of course, it was changes in the humors of the body that constituted the main causes for disease in her opinion, but it is well to remind ourselves that our frequent discussion of auto-intoxication in recent years is a distinct return to this. Some of Hildegarde's anticipations of modern ideas are, indeed, surprising enough. For instance, in talking about the stars and describing their course through the firmament, she makes use of a comparison that is rather startling. She says: "Just as the blood moves in the veins which causes them to vibrate and pulsate, so the stars move in the firmament and send out sparks as it were of light like the vibrations of the veins." This is, of course, not an anticipation of the discovery of the circulation of the blood, but it shows how close were men's ideas to some such thought five centuries before Harvey's discovery. For Hildegarde the brain was the regulator of all the vital qualities, the centre of life. She connects the nerves in their passage from the brain and the spinal cord through the body with manifestations of life. She has a series of chapters with regard to psychology normal and morbid. She talks about frenzy, insanity, despair, dread, obsession, anger, idiocy, and innocency. She says very strongly in one place that "when headache and migraine and vertigo attack a patient simultaneously they render a man foolish and upset his reason. This makes many people think that he is possessed of a demon, but that is not true." These are the exact words of the saint as quoted in Mlle. Lipinska's thesis.
