中药由原药材加工成饮片,一般要经过洗、浸、泡、漂、润、切、烘等工序。经过这些工序对药物的质量将会受到不同程度的影响,甚至使有效成分大量流失。例如大黄、天花粉等置水中浸泡1小时后有效成分即开始溶出,在浸泡过程中也容易发粘、发臭、变色等现象,尤其在热天更甚。肉质的肉苁蓉在产地处理有二种:即春季采者通常半埋于沙土中干燥称甜苁蓉;秋季采者因水分多,不易晒干,须投入盐湖中,1—3年后取出晒干称盐苁蓉(又称咸苁蓉)。前者切片前要浸润至透;后者更要浸漂三日,每天换水,漂去
Traditional Chinese medicines are processed into raw pieces from raw herbs, which are usually washed, soaked, soaked, rinsed, moistened, cut, and dried. After these procedures, the quality of the drug will be affected to varying degrees, and even a large amount of active ingredients will be lost. For example, rhubarb, trichosanthin, etc. in the water after soaking for 1 hour after the active ingredient began to dissolve, in the soaking process is also easy to stick, odor, discoloration and other phenomena, especially in hot days. There are two kinds of succulent Cistanche at the place of production: Spring growers are usually semi-buried in sand and dry as sweet cistanche; autumn cultivars have more water and are not easy to dry, they must be thrown into the salt lake, and they should be taken out after 1-3 years. It is called salt cilia (also known as salt cilia). The former must be infiltrated thoroughly before slicing; the latter should be immersed in water for three days.
