部分中药有毒,但经过炮制后,毒性降低或消除。但毒性中药炮制前后微量元素的变化却研究的很少,现我们选半夏、天南星、白附子三种中药,关于其炮制前后的微量元素变化未见报道,下面将其炮制前后微量元素作含量测定,报告讨论如下。 Some Chinese herbs are toxic, but after concoction, the toxicity is reduced or eliminated. However, little research has been done on the changes of trace elements before and after processing of toxic Chinese medicines. Now we have selected three kinds of Chinese herbs: Pinellia ternate, Arisaema, and Aconite. There are no reports on the changes of trace elements before and after processing. The trace elements before and after processing are used as the contents below. Assay, the report is discussed below.
