馬錢子是中西医都用的一种毒性較强的生药。中医一般使用炮制过的药品,据說炮制操作可以降低其毒性。現在全国各地炮制方法不尽相同,有油炸法、砂炒法(砂烫法)、水煮法等等;有要求刷净茸毛的,也有不要求刷净茸毛的。各种炮制方法对其主要有效成分变化的影响究竟如何,尚未見到报道。为了进行这方面的探討,我們以北京地区习用的砂炒法炮制过 Ma Zhongzi is a more toxic crude drug used by both Chinese and Western medicine. Chinese medicine generally uses concocted medicines, and it is said that concoctions can reduce its toxicity. Now the processing methods are not the same throughout the country, there are fried method, sand frying method (sanding method), boiled method, etc.; there are requirements to brush the net hair, but also does not require the brush net hair. The effect of various processing methods on the changes in its main active ingredients has not yet been reported. In order to carry out this discussion, we have used the sand-shaving method commonly used in the Beijing area.
