Asbab Musakhkhina are the causative factors that increase heat in the body according to Unani medicine.
Examples include excessive movement (Harkat), blockage due to waste (Sudda basabab Fuzlat), and putrefaction or infection (Ufoonat).
These all lead to increased heat production or retention in the body.
However, Mo’tadil Miqdar ki Ghiza means taking food in moderate quantity — this supports balance and does not generate excess heat.
Hence, it is not considered an Asbab Musakhkhina but rather a part of healthy regimen to maintain Mizaj.
Therefore, option (1) is the correct answer.
