Respiratory Disease History
circa 1550 BCE, Ebers Papyrus, ancient Egypt
Asthma is one of the oldest recorded respiratory conditions in human history, with descriptions appearing in ancient Egyptian and Greek texts. For centuries, physicians debated whether it originated in the heart, lungs, or nervous system, and treatments reflected the dominant medical theories of each era. The gradual shift toward understanding asthma as a condition of the airways unfolded over more than two millennia of observation and experimentation.
Historical Narrative
The earliest known written reference to a condition resembling asthma appears in the Ebers Papyrus from ancient Egypt, dating to around 1550 BCE. Egyptian healers prescribed a mixture of herbs heated on bricks, with patients inhaling the resulting vapors — a practice that reflected an empirical, if not fully understood, approach to respiratory relief. The word 'asthma' itself comes from the ancient Greek word meaning 'to pant,' and Hippocrates in the 5th century BCE used it to describe episodes of labored breathing, though he did not fully distinguish it from other respiratory ailments.
Galen of Pergamon, writing in the 2nd century CE, theorized that asthmatic episodes resulted from mucus accumulating in the bronchi and partially obstructing the passage of air. His explanations, rooted in the humoral theory of disease, dominated Western medical thinking for over a thousand years. Medieval Islamic physician Ibn Sina, known in the West as Avicenna, provided detailed descriptions of breathing difficulties in his monumental Canon of Medicine, recommending treatments that included chicken soup, specific herbal preparations, and changes in living environment — advice that was considered authoritative well into the Renaissance period.
During the 17th century, the Belgian physician Jan Baptist van Helmont was among the first to suggest that asthma originated specifically in the bronchial tubes rather than in the stomach or heart. His observations helped begin a slow conceptual shift in European medicine. Around the same time, Thomas Willis, an English physician known for his work on the nervous system, proposed that asthmatic episodes might be connected to nervous system spasms affecting the lungs — a hypothesis that kept the neurological theory alive for generations.
The 18th century brought more systematic investigation. John Floyer, an English physician who himself experienced breathing difficulties throughout his life, published 'A Treatise of the Asthma' in 1698, providing one of the earliest sustained clinical observations of the condition across a lifetime. He noted the episodic nature of the illness and its apparent relationship to environment, physical exertion, and season. His work was influential in pushing asthma toward being understood as a distinct condition rather than a symptom of other diseases.
In the 19th century, French physician René Laënnec, who invented the stethoscope in 1816, used his new instrument to listen to the lungs of patients during breathing episodes, providing clearer physical evidence of what was happening inside the chest during an attack. His observations helped reinforce the bronchial origin theory. By the late 19th century, Henry Hyde Salter in Britain published extensively on asthma's episodic nature and its apparent links to allergy and nervous system activity, laying groundwork for the immunological investigations that would follow in the 20th century.
Throughout this long history, asthma was variously blamed on damp climates, nervous temperament, hereditary weakness, and even moral character. Treatments ranged from inhaling tobacco smoke, burning stramonium herb preparations, and drinking strong coffee to elaborate spa cures and changes in altitude. Each era's treatment reflected its theoretical framework rather than a unified understanding of what was actually occurring in the lungs.
