(L.) b2:  أَصَابَهُ مِنَ الحَرِّ لَفْحٌ وَمِنَ البَرْدِ نَفْحٌ [A blast of heat smote him, and a blast of cold].

(TA.) [It seems that the application of the term لفّاح to both the mandrake and the شمّام has led to confusion, and occasioned Linnæus to call the latter “ cucumis  dudaim. ” See also يَبْرُوحٌ, and مَغْدٌ.]لَافِحَةٌ: see لَفْحٌ.
