This handbook is intended for physicians who, beyond relying on well-established and approved medications, are seeking new remedies in the field of folk medicine and wish to incorporate their clinical experience in phytotherapy and herbal healing. Their motivation may stem not only from curiosity but also from the individual needs of certain patients who prefer natural treatments—those inclined toward “herbal medicine” and avoiding chemical, potent, and aggressive drugs. These patients are not self-medicating but want to be treated under a doctor’s supervision. However, the demanding conditions of modern life often leave doctors little time to explore literature on folk medicine to find the necessary information for treating various ailments. To meet their needs and respond to their requests, the author has revisited and compiled therapeutic insights from his previously published work, *Medicinal Plants in Folk Medicine*, along with other similar texts, organizing this knowledge by specific diseases for easier reference.
