通过对紫苏Perilla frutescens(L.)Britt.的名称、产地、功效、基原植物四方面进行本草考证,认为“紫苏”与“白苏”只是种内形态差异,在植物分类学上应命名一种;但颜色的差别可以作为传统鉴定的方法之一,选择色紫者入药。为“紫苏”和“白苏”的植物学命名和紫苏的正本清源提供参考依据。 Through the research on the name, origin, and efficacy of the perilla frutescens (L.) Britt., the four basic aspects of the original plant, it is considered that the “perilla” and the “white susu” are only morphological differences within the plant. Taxonomy should be named one; but the difference in color can be used as one of the traditional methods of identification, choose purple color as the drug. It provides reference for the botanical nomenclature of Perilla and Perilla and the original source of perilla.
