باِسْمِ اللَّهِ تُرْبَةُ أَرْضِنَا بِرِيْقَةِ بَعْضِنَا يُشْفَى (بِهِ) سَقِيْمُنَا بِإِذْنِ رَبِّنَا

Bismil-laahi, turbatu ardina, biriqati ba`dina, yushfa (bihi) saqimuna, bi 'idhni Rabbina

In the Name of Allah The earth of our land and the saliva of some of us cure our patient. Ayesha (RA) said that if there was any illness, pain or wound on any part of the body, Rasulullah (ﷺ) would place his (Shahadat) finger on the ground and lift it and recite this Dua. In another narration, he would put a little saliva of his mouth on his finger and put his finger on the ground and then put it in the place of pain and say this dua.
