Sinusitis is the inflammatory condition involving paranasal sinuses. The paranasal sinuses are air filled spaces in certain bone of skull and they are in direct communication with nasal cavity through their opening called ostia. The clinical manifestation of sinusitis is nasal discharge, headache, blocking of nose, changed nasal resonance, post nasal drip and pain with tenderness in affected sinus. It may be associated with fever occasionally. If the symptoms of sinus inflammation lasting >3 months, then the condition is called chronic sinusitis. 1,2,3,4,5 . There is no separate description of chronic sinusitis (Iltehahabe Tajaweef-e-Anaf Muzmin) in Unani literature. Several Unani physicians have described Nazla in lieu of the signs and symptoms of Warm Tajaweef-e-Anaf (sinusitis), with its types haad and muzmin 6,7,8 . Therefore the search for sinusitis in unani literature seems evasive, but the Unani physicians have rendered the description of Warm (inflammation), tajaweef (Cavities) and Majari (ducts), which can be correlated to present modern concept of sinusitis 9,10 . The terms Iltehahabe Tajaweef-e-Anaf, Nazla, Zukam and Catarrah are used as synonymous for sinusitis which is classified in haad and Muzmin (acute and chronic). So, keeping the fact in mind want to established the clinical correlation with anaemia in the light of classical Unani literature as well as modern medicine.
