Perilla is the common name for a herb of the mint family, Lamiaceae. Though known to several cultures by different names, the disparate varieties are now classified under the single species Perilla frutescens.

The overall plant resembles the stinging nettle, though the leaves are somewhat rounder.

The culinary variety is known as shiso, from its name in Japan, where it is an important part of diet and cuisine, or beefsteak.[1] It comes in both green- and purple-leafed forms. They are also used in China, although there it is not a mainstay herb. It is also used among many other mint and basil type herbs in Southeast Asian countries. The distinctive aroma and pungency of the shiso type might be compared to that of mint or fennel.
