水牛角是牛科动物水牛的骨质角（BS加NSbubalisL．）。本品具有清热解毒，凉血定惊之功效。以前我院炮制水牛角，均采用传统的切片或铁成细粉方法。该法因切片厚薄不均，且易粘刀，难于保证饮片质量，经试验采用WZQ－3型转盘切药机（长春市药材机械厂产）刨片的方法炮制水牛角 Buffalo horn is the bony angle of the bovid buffalo (BS plus NSbubalis L.). This product has the effect of clearing heat and detoxifying, cooling blood and getting scared. In the past, buffalo horns were made in our hospital using traditional methods of slicing or iron into fine powder. This method is not uniform because of the thickness of the slice, and easy to stick knife, it is difficult to guarantee the quality of the pieces. After the test, the WZQ-3 rotary table cutting machine (produced by the Changchun Medicinal Materials Machinery Factory) was used to make the buffalo horn.
