藤、木类药材根据炮制规范,入药需要劈成碎块。但这类药材质量坚硬,操作时劳动强度大,工作效率低。笔者在实际工作中摸索出了一些规律,可减轻劳动强度,提高工作效率。一、木类药材劈法技巧: 1.分清根和梢:苏木、松节、檀香、降香等均为木质坚硬的药材,这些药材一般情况下根粗梢细可明显区分。但购进药材大多已分成一段一段的,在一段范围内两端粗细无明显区分。这时可根据“根重梢轻”的道理,在药段中间系一细绳,提起细绳,下垂的一端为根部,另一端为梢部。2.锯时作标记:需要劈成碎块的药
According to the concocted specifications, rattan and wood medicines need to be chopped into pieces. However, such medicines are of a hard quality, have a large labor intensity during operation, and have low work efficiency. The author has worked out some laws in practical work, which can reduce labor intensity and increase work efficiency. First, the wood medicine herbs method tips: 1. Distinguish the roots and shoots: hematoxylin, pine knot, sandalwood, incense and other are all hard wood medicine, these herbs under normal circumstances can clearly distinguish the root tips. However, most of the purchased herbs have been divided into one segment, and there is no clear distinction between the thickness of the two ends within a certain range. At this time, according to the principle of “light weight”, a string is tied in the middle of the medicine segment and the string is lifted. The hanging end is the root and the other end is the tip. 2. Marking when sawing: drugs that need to be crushed
