Application of glabrous sarcandra herb injection in atomization, rectum, oral administration and acupoint injection and preparation method of glabrous sarcandra herb injection

The invention relates to a preparation method of a glabrous sarcandra herb injection, the preparation method of the glabrous sarcandra herb injection is concise and ingenious in steps and easy to control, glabrous sarcandra herb is cleaned through a glabrous sarcandra herb cleaning step, and the cleaned glabrous sarcandra herb is crushed through a glabrous sarcandra herb crushing step. According to the step of soaking and boiling the glabrous sarcandra herb, the crushed glabrous sarcandra herb is soaked, heated and boiled to obtain a glabrous sarcandra herb mixed solution. The glabrous sarcandra herb mixed liquor is filtered through the glabrous sarcandra herb mixed liquor filtering step, and glabrous sarcandra herb filtrate is obtained. The glabrous sarcandra herb filtrate is concentrated and dried through the glabrous sarcandra herb filtrate concentration step to obtain the glabrous sarcandra herb extract. And drying the glabrous sarcandra herb extract through a glabrous sarcandra herb extract drying step t
