Asthma in historyAsthma in history

... A disease, emphasizing the wheezing, the dry, often non productive cough, and the inability to sleep in a prone position. The disease called ortopnoia is also called asthma ..... ....They eagerly go into the open air, since no house sufficieth for their respiration.........cough incessant and laborious, expectoration small, thin, cold, resembling the efflorescence of foam........if these symptoms increase, they sometimes produce suffocation......

Page 4: RHINITIS AND ASTHMA: UNITED AIRWAY DISEASE Dr. İ.Kıvılcım Oğuzülgen Gazi University School of Medicine, Department of Pulmonary Medicine Ankara, Turkey.

Aretaeus of Cappadocia described asthma with care, attributing it to thick and viscid phlegm caused by coldness and humidity suffered by the patient.

Rhinitis in historyRhinitis in history

About the beginning or middle of the June every year....

... a sensation of heat and fulness is experienced in the eyes...

... to this succeeds irritation of the nose producing sneezing

To the sneezing are added a further sensation of thightness of the chest, a difficulty of breathing
