초록
Gageum annotated the text of Sanghannon - Rigor with fever comes from yang and rigor without fever comes from yin. - that 'comes from yang' was the state already shown the fever and 'comes from yin' was the state not yet shown the fever, so he told that yang disease without fever belonged in 'comes from yin' and yin disease with fever belonged in 'comes from yang'. And he annotated the text - If one purges the disease comes from yang, the fever goes into the inside and it becomes Gyeolhyung. And if one purges the disease comes from yin, it becomes Bijjeung. - that yin meant the inside and yang meant the outside. That is to say, he distinguished two texts independently. And he presented the pathological reason that cold medicines such as sorts of Sasim-tang were used to cure Bijjeung.
