查阅有关北沙参的文献资料,对北沙参原药材的采收与产地加工方式进行了综述。北沙参的采收主要在夏秋两季,一般是秋季播种,第2年秋季采收并加工,2~3年生参也可以夏季采收。采收后加工前注意避免日晒,否则会干后不好去皮,可用湿砂掩埋,或用湿麻袋覆盖。加工时,先去掉茎叶,再把根部洗净、稍晾,按粗细大小进行分级、捆把,再用水烫,注意控制好水的温度及时间,再手工去皮、晒干,即得。实验证明:北沙参沸水烫后剥皮的加工方法,费工费时,而且损失了药材大部分有效成分,显著降低了疗效,因此建议北沙参应带根皮入药。较早文献有炒制、蜜制、米制的记载,现临方炮制仍用到蜜制的方法。
Refer to the literature about Beigang ginseng, and summarize the methods of harvesting and producing the origin of Radix isatidis. North ginseng harvest mainly in summer and autumn, usually autumn seeding, autumn harvest and processing the second year, 2 to 3 years of raw ginseng can also be harvested in the summer.
