Abstract. Abstract. A more detailed and accurate clinical picture of asthma was described by Aretheus of Cappadocia (1st century AD) in his essay “On the Causes and Symptoms of Chronic Diseases”, devoting a separate chapter to it. Areteus in his essay described two forms of the disease, accompanied by difficulty in breathing, noting that one of them, characterized by orthopnea, is associated with heart disease; the second, provoked by cold moist air and accompanied by spastic difficulty in breathing and wheezing, is a disease of the lungs—thus. Aretaeus divided asthma into two forms: cardiac and bronchial. Claudius Galen, who wrote, among other works, the work “On Difficulties in Breathing” (lat. De difficultate respirationis), adhered to the Hippocratic approach to explaining the causes of asthma, explaining them by the accumulation of viscous sputum in the bronchi and, following Areteus, accepting the division of asthma into two forms.
