即使是有的古文献有记载的东西,还必须全面考虑它是否在中医药发展过程中产生过影响,是否占主流,是否能成为中医的代表性意见。只择一家之说,便指为整个中医的看法,这是不合历史唯物观的。整理、甄别古文献记载,从源流上阐明其历史原貌,可以增强实验研究的说服力。如张颖才全面考虑了古代有关麦冬去心的记载,指出历史上也有很多认为麦冬不必去心,甚至反对去心的记载;金世元考证连翘在古代一般足连心(种子)用的,去心仅见于部分医药书中。这些考证为麦冬,连翘是否应去心提供了重要的文献依据。而不注意文献考察,有时所下结论则不免差强人意。如有人从抑菌试验结果出发,认为银花藤具有与银花相同的作用,于是提出可用银花藤作为银花解毒的“代用品”。可是实际上中医早就认识到银花藤的解毒作用,用藤解毒比用花还要早好几百年。从理论上说,在中药研究课题设计中,文献考察应该先行,这样有利于找出问题的症结,完善整体研究方案。同时文献考察本身常常可以解决部分实际问题。例如有些地方加工桔梗时要刮去外皮,这一作法是不是有其实践经验呢?《本草纲目》记载桔梗只须 Even if there are records in some ancient documents, it must be fully considered whether it has had an impact in the development of Chinese medicine, whether it has become mainstream, and whether it can become a representative opinion of Chinese medicine. Only the one-choice one refers to the view of the entire Chinese medicine. This is not compatible with historical materialism. Sorting out and screening ancient documentary records and clarifying their original appearance from the source stream can enhance the persuasiveness of experimental research. If Zhang Yingcai fully considered ancient records about Ophiopogon’s heart, he pointed out that there are also many records in history that Ophiopogon don’t need to go to heart, and even object to the record of the heart; Jin Shiyuan’s textual research on forsythia used in ancient ancient foot (seed) The heart is only found in some medical books. These researches provide important literature basis for Ophiopogon japonicus and forsythia. Without paying attention to literature inspections, sometimes conclusions are inevitably conveyed. If someone starts from the results of the antibacterial test, it is believed that Yinhuateng has the same effect as silver flower, so the silver vine can be used as a “substitute” of Yinhua detoxification. However, in fact, traditional Chinese medicine has long recognized the detoxification effect of silver flower vines, and using vines to detoxify them hundreds of years earlier than using flowers. In theory, in the research project design of traditional Chinese medicine, literature review should be conducted first, which is helpful to find the crux of the problem and improve the overall research program. At the same time, the literature review itself can often solve some practical problems. For example, in some places, when processing Campanulaceae, it is necessary to scrape the outer skin. Is this practice practical experience? The “Compendium of Materia Medica” records only
