中药产生的药理作用不完全归因于其特有的化学组分及成分结构，还与药物的物理状态密切相关。将纳米技术引入现代中药制剂的研究与开发，有望将中药制成高效、速效、长效、剂量小、不良反应少、服用方便的现代制剂，可以提高中药的临床疗效，扩大中药的应用范围，并且丰富中药的理论研究。对近年来纳米技术在中药制剂研究中显现的优势与应用进行综述。

The pharmacological function of Chinese medica medica (CMM) does not entirely due to its unique chemical composition and constituent structure, it is also closely related to its physical condition. Introducing modern nanotechnology into the research and development of CMM preparation, CMM is expected to be made modern formulations which is efficient, quick, long-lasting, small doses, little adverse reactions, and easy to take. That can expand the research of the theory of CMM and enlarge the range of the application in TCM. In this article the recent application of nanotechnology in the research of TCM preparation has been reviewed.
