In the Middle Ages, lovesickness was regarded as a genuine medical condition, deeply rooted in the humoral theory of medicine. This theory, based on the writings of ancient physicians like Galen, posited that the human body was governed by four humors: blood, phlegm, black bile, and yellow bile. A balance among these humors was essential for good health, and any imbalance could lead to illness. Lovesickness, or \"amor hereos,\" was believed to result from an excess of black bile, leading to melancholy. Symptoms included insomnia, loss of appetite, palpitations, and obsessive thoughts about the beloved. Medieval physicians treated lovesickness with a variety of remedies aimed at restoring humoral balance and soothing the afflicted soul.
Treatment for lovesickness often involved exposure to light and nature, as it was thought that the beauty of gardens and the calming effect of natural surroundings could alleviate the symptoms. Rest and relaxation were also prescribed to help the patient recover from the emotional turmoil. Inhalations of fragrant herbs and warm baths were used to soothe the body and mind. Dietary recommendations included foods believed to have a cooling and calming effect, such as lamb, lettuce, eggs, fish, and ripe fruit. These treatments reflect the medieval understanding of the interconnectedness of body and soul, and the belief that physical and emotional health were deeply intertwined. The concept of lovesickness highlights the medieval approach to medicine, where emotional states were considered just as important as physical symptoms in diagnosing and treating illness
