槟榔为种子类中药,因个实质坚硬在饮片切制前常用冷水长时间浸泡,可是槟榔的有效成分——槟榔碱易溶于水,长时间水处理会导致有效成分流失,而影响药材质量;有些地方为了防止槟榔碱的流失,而用捣碎的办法,这又影响了饮片的形状。若采用河砂埋润槟榔的办法,既能减少有效成分的流失,又能保证饮片形状的美观。其方法如下:取一能漏水而不能漏河砂的容器,在底层铺一层河砂,在砂上放一层槟榔,用水淋 The betel nut is a kind of seed traditional Chinese medicine. Because it is hard and hard to soak in the cold water for a long time before cutting the pieces, but arecoline, an active ingredient of the betel nut, is easily dissolved in water, and long-term water treatment will lead to the loss of active ingredients and affect the quality of the herbs. In some places, in order to prevent the loss of arecoline, smashing methods were used, which in turn affected the shape of the pieces. If river sand is used to bury betel nut, it will not only reduce the loss of active ingredients, but also ensure the beauty of the shape of the pieces. The method is as follows: Take a container that can leak water without leaking sand, lay a layer of river sand on the bottom layer, put a layer of betel nut on the sand, and apply it with water.
