RESUMEN
Temperament [mizaj] occupies a very important place in Unani medicine. Every normal person has a different temperament in different period of age as Sin-e-Namoo [birth to 25 years] and Sin-e-Wayoof[26 to 40 years] demonstrate sanguine and phlegmatic temperament respectively. However, it is yet to be tested clinically. In this study, temperament of two age groups was tested clinically. A total of 100 normal volunteers of either sex were examined by psychological, physiological and morphological parameters to determine the temperament of two age groups Sin-e-Namoo and Sin-e-Wagoof. Majority of the volunteers was related to sanguine and phlegmatic temperament. Sanguine and phlegmatic temperament of Sin-e-Namoo and Sin-eWagoof age groups justified the reported claim of Unani medicine
