Abu Ali Sina (known in the West as Avicenna) placed his hand on the patient’s pulse, and mentioned the names of the different districts and continued until he reached the name of a quarter at the mention of which, as he uttered it, the patient’s pulse gave a strange flutter. Then Abu Ali repeated the names of different streets of that district and different houses till he reached the name of a house at the mention of which the patient’s pulse gave the same flutter. Finally, he uttered the name of different households of that house until he reached a name at the mention of which that strange flutter resumed. Thereupon he said: This man is in love with such-and-such a girl, in such-and-such a house, in such-and-such a street, in such-and-such a quarter: the girl’s face is the patient’s cure” ....This is how the Iranians used the pulse rate in ancient times long before western knowledge....It might surprise you that till 400 years ago the only texts in western medical universities were of Abu Ali ibn Sina ....
