藏药佐太炮制工艺历史沿革探析及炮制辅料使用原理解析OA

The processing technology of Tibetan medicine Zuotai was established by OrgyenPa Rinchenpal in the 13 th century after studying mercury processing technology in India,Wuzhangna and other places.Its core processes include rust removal,rust removal solution,detoxification and shaping.At present,the research on the inheritance of Zuotai's processing techniques and the history of the use of auxiliary materials is not in-depth enough.In addition,the processing technology of Zuotai is complex,and uses a large variety of auxiliary materials,making its processing principle difficult to understand.In view of this,this article has systematically sorted out the historical evolution of Zuotai processing technology and processing materials,organized the changes in processing materials across different periods,analyzed the principles behind the use of processing materials in Tibetan medicine,and,by combining with the theory of Tibetan medicine processing,preliminarily explored the processing principles of Zuotai.The historical evolution of Zuotai's processing techniques has gone through three stages of inheritance:Absolute one-way inheritance from the 13 th to the 15 th century,relative one-way inheritance from the 15 th to the 17 th century,and branching inheritance from the end of the 17 th century.During this evolution:In the 15 th century,the types of saline and alkaline drugs were enriched;In the 17 th century,the rust-removing solution step was supplemented with adjuvants such as sour wine,garlic water,meat broth,and ghee,while the use of"Eight Metals Ash"(Ba Jin Hui)was restored;In the 18 th and 19 th centuries,the washing and boiling process was refined;and since the 20 th century,based on the inheritance of the use of excipients from ancient texts,the processing excipients have become more abundant,and the processing techniques have been further refined.Zuotai's processing ingredients are mainly used to raise gastric temperature and promote digestion,while also possessing detoxifying effects.They can be used to treat conditions such as diminished gastric fire and indigestion caused by mercury toxicity.The principle of Zuotai processing involves removing the"rough"nature of mercury's"rust-like"toxicity through the rubbing-rust and rust-removing solution steps;reducing the"heavy"and"sharp"properties of mercury via the washing and boiling detoxification steps and then transforming the nature of mercury through combination with processed sulfur to form a stable product.In this way,mercury is converted into non-toxic and effective Zuotai medicine.This article clarifies the historical evolution of the processing technology and auxiliary materials of Zuotai,and preliminarily explores the principles of medication and processing principle of auxiliary materials,providing theoretical basis for the inheritance and research of Zuotai processing technology.
