山东“莱阳沙参”是商品“沙参”中全国闻名的一种,而且还是主要出口药材之一,在国内外都有相当高的信誉。以其为我国北方产品,所以又叫“北沙参”以与南方产沙参相区别。“莱阳沙参”是(?)形科植物,珊瑚莱(滨防风)Glehnia littoralis Fr.Schmidt ex Miq,(Phellopteruslittoralis Benth)的根部。以植物基源来说,就和“南沙参”(桔梗科)有着根本上的不同。本植物茎高一尺左右,叶为二回三出复叶,质厚而有光泽,边缘具锯齿,叶柄红紫色。夏日茎顶密生红色小花,排列成复(?)形花序,花轴和花梗密生红色毛茸,花药暗紫色,果实为双悬果,其上留存的花柱亦带紫色,根直而长,身细而均匀。仅就根的外形来说,也和“南沙参”有着明显的区别。“莱阳沙参”在山东多为栽培品,主产于莱阳、牟平、海阳等县,其中尤以莱阳为最多;此外,在掖县、黄县、抬远、蓬莱、乳山、海阳沿海1600余里的沙滩上也都有野生。
