Nazla (Catarrh) is a condition in Unani medicine that involves the flow of catarrhal fluids, or mucus, from the brain downwards into the throat and chest, leading to symptoms similar to what we consider a cold today. This condition is characterized by congestion, irritation in the respiratory pathways, and in some cases, can progress to more serious respiratory complications if left untreated. While preparing a detailed catalogue of Unani medical manuscripts housed at the Telangana Government Oriental Manuscripts Library and Research Institute (TGOMLRI) in Hyderabad, a significant discovery was made: a concise yet vital manuscript titled Risala Tahaffuz min al-Nazla (A Treatise on the Prevention of Cold and Catarrh), cataloged under Accession No. 8880. This manuscript, written by the eminent physician Muhammad ibn Zakariyyā al-Rāzi (865–925 AD), offers invaluable insight into the traditional understanding and prevention of the common cold. Al-Rāzi, also known as Rhazes in the Latin world, was one of the most influential figures in the history of medicine, contributing profoundly to clinical practices and medical theories that remained relevant for centuries. This treatise, written in Arabic, reflects al-Rāzi's keen focus on preventive medicine, specifically on measures to avoid the onset of cold and catarrhal conditions. It is a paper manuscript, notable for its brevity, consisting of only 8 pages. Each page contains 14 lines, with an average of 16 letters per line, displaying a compact and highly structured layout that suggests its use as a practical guide. Its focus on prevention rather than solely treatment is particularly notable, as it aligns with al-Rāzi’s broader medical philosophy emphasizing lifestyle and precautionary health measures. Moreover, Risala Tahaffuz min al-Nazla outlines remedies based on herbal medicine, prescribing specific herbs and natural compounds known to alleviate symptoms of cold and prevent its occurrence. These herbal prescriptions include ingredients that are easily available in Unani medicine and have historically been used for their anti-inflammatory, expectorant, and warming properties, which can relieve respiratory congestion and discomfort. Interestingly, another copy of this treatise exists in Iran, underscoring the historical and scholarly connections between Indian and Persian centers of Unani medicine. This manuscript’s discovery in Hyderabad adds to the rich collection of Unani medical texts in India, showcasing the traditional medical knowledge that continues to be studied for its relevance to modern alternative medicine practices. Through such manuscripts, Unani medicine remains an enduring part of the cultural and scientific heritage in regions with strong historical ties to Persian medical traditions. The concise nature of Risala Tahaffuz min al-Nazla and its practical content makes it a valuable text for both historical research and contemporary applications, providing insights into how ancient Unani physicians approached the common cold with holistic, plant-based remedies.
