藏医妊娠学说的来源

Origin of Gestation Theory in Tibetan Medicine

学术界对藏医妊娠学说的来源，向来认为只一种且是本土的妊娠学说，本文证明有两种并都来自印度。一种为《四部医典》，它是印度《八支医方要集》和《大宝积经》妊娠论的综合；另一种为《月王药诊》，是依据《大宝积经》而来。藏医经典《月王药诊》和《四部医典》（有关妊娠论）现行版本写定年代向未确定。本文根据文献的语文特征，认为前者写定于藏文《大宝积经》译出（９世纪）以前；后者写定在藏文《八支医方要集》译出（１０～１１世纪）以后。

Generally,it is claimed that gestation theory was originated locally in Tibet,with only a single origin.This author proves that there are two sources,both derived from India.One is a combination of gestation theory from rGyud-bzhi,i.e.Astangahrdayasamhita,and the Great Ratnakuta,and the other,from Somaradza,also derived from the Great Ratnakuta.The dates of writing of modern edition of Somaradza and rGyud-bzhi are still uncertain yet.Based on the linguistic features,this author claims that Somaradza was written before the Tibetan version of Great Ratnakuta(9century),while rGyud-bzhi,after the translation of Astangahrdayasamhita(10～11 century).
