In Unani medicine, Jhaw (wild mustard) is known to have an irritant effect on the throat when used internally or inhaled.
The term Muzir Halaq specifically means harmful to the throat.
Therefore, Jhaw is classified as producing the effect of Muzir Halaq.
Muzir Sar means harmful to the head, Muzir Bah means harmful to virility, and Muzir Basar means harmful to eyesight — none of these are specifically linked to Jhaw’s primary irritant property.
So, option (2) is the correct answer.
