龟板是重要的滋阴药物。由于传统习惯,至今临床使用的龟板一般为龟的下甲,即腹甲,而龟上甲即外壳一般视为无药用价值被废弃,因而长期以来加重了龟板药源的紧缺,不能满足临床需要。据有关中医文献证实,我国宋代以前是以龟全甲(上、下甲)入药的,主要取其活血止痛的功效,用于治疗伤科、妇科等疾病。只是到了元代,朱丹溪发现了龟板(下甲)有滋阴作用后,上甲才被废弃。1986年,中国中医研究院的杨梅香等同志对龟的上、下甲的化学成分,药理、毒理等做了大量的实验研究工作,证明:(1)龟上、下甲具有相同的化学成分,且龟上甲的 Turtle is an important nourishing medicine. Due to traditional practice, the turtle shells used so far are generally the lower armor of the turtle, that is, the plastron, while the shell of the turtle is generally regarded as having no medicinal value to be discarded. Therefore, the shortage of the turtle shell medicine source has been aggravated for a long time and cannot meet the clinical requirements. need.

It was only in the Yuan Dynasty that Zhu Danxi discovered that turtle shells (a lower armor) had nourishing yin. The upper armor was abandoned.

It was proved that: (1) Turtle upper and lower armor have the same chemistry Ingredients, and Turtle on a
