Cauterization(Perian:Dāgh/Arabic:Al-Kayy or Al-Wasm)is one of the oldest methods of treatment in most ancient cultures and medical schools;the history of these methods,with archaeological studies,is estimated to be more than a few thousand years,and this issue can determine the reason for the spread of cauterizing methods in the traditional medicine of ancient civilizations,including Iran and China.The present research,as a descriptive/historical research,tries to examine the text of the manuscript of Tanksuq-nāmeh;and identify the theoretical foundations and practical methods of cauterization in Chinese and Khitans medicine,based on one of the key texts of the Ilkhanid period.(Text translated from Chinese to Persian in the 14th century AD)The results of the present study show that cauterization has a long history among the Chinese and Khitans peoples and has been performed in different ways and for different diseases.
