临床处方中不常用的或用量少的药材我们称之为小宗药材。由于此类药材,价格低、流通不畅经常造成品种短缺。如果一个方剂中缺药少药配方不齐,医生处方再科学合理也会影响疗效,达不到治疗目的。因此,搞好小宗药材合理购销,保证中药配方齐全具有临床意义。历来小宗药材购销都存在困难,不是积压就是脱销。原因是:在药材经营部门中存在着“重大宗轻小宗”、的思想。小宗药材价格低而且用量不大,产量低不易采收;这些品种一般多为野生,如:柽柳、密蒙花、芫花、蚤体、桔络、豨莶 The medicines that are not commonly used or used in small amounts in clinical prescriptions are called small medicines. Due to the low price and poor circulation of these herbs, there is often a shortage of varieties. If a formula lacks prescriptions for missing drugs and drugs, the doctor’s prescription will be scientifically reasonable and will also affect the therapeutic effect, failing to achieve therapeutic goals. Therefore, it is of clinical significance to do a reasonable purchase and sale of small medicinal herbs to ensure that the complete preparation of traditional Chinese medicines is complete. Historically, there have been difficulties in buying and selling small medicines, which are either out of stock or out of stock. The reason is: In the medicinal materials business department, there exists the idea of ​​“major cases of minorities, minorities, and minorities.” Small medicinal herbs are low in price and small in usage, and their yield is low and they are not easy to harvest. These varieties are generally mostly wild, such as Tamarix chinensis, Buddleja officinalis, coriander flowers, coriander seeds, orange colander and coriander seeds.
