写作思路首先是介绍中医药材的来源，其次讲中医药材的应用。具体介绍描述如下：Speaking of Chinese Medicine Culture， as it has a long history of thousands of years， so its details are very rich.说到中国的药文化，由于它有着数千年的悠久历史，所以其底蕴十分丰富。 However， both Chinese and foreigners lack a comprehensive and profound understanding of its rich cultural connotation， which leads to some misunderstandings.然而，无论是中国人，还是外国人，对其丰富的文化内涵缺乏全面深刻的理解，故而导致某些误识。The earliest monograph of Chinese Materia Medica in China was the Shennong Ben Cao Jing in the Han dynasty.我国最早的一部中药学专著是汉代的《神农本草经》.Traditional Chinese Medicine is an indispensable part of Chinese culture. It has made great contributions to the prosperity of China.中医是中华文化不可分割的一部分，为中华的繁荣昌盛做出了极大的贡献。Nowadays， both Traditional Chinese Medicine and western medicine are being used to cure people all around the world. 如今，中医和西医都被世界各地的医生用来治疗疾病。The TCM， with its unique diagnostic methods， long history and remarkable effects， have been used to treat cancer and other serious diseases. 中医，以其独特的诊断手法、悠久的历史和显著的疗效被用来医治各种癌症和重大疾病。Unlike the western medicine， the TCM has fewer side effects.中药不像西药那样会产生许多副作用。
