Perilla, also known as Eun, Hongsu, Xiangsu, etc., is native to East Asia and is now mainly distributed in China, South Korea, Japan and some Southeast Asian countries. China is the country with the largest planting area and annual export volume of perilla , both as spice and edible.

Perilla seeds are the dried and mature fruits of the medicinal plant Perilla frutescens, generally gray-brown or gray-brown spherical shape, with patterns on the surface, crushed and fragrant. "Compendium of Materia Medica" records that "the seeds are harvested when the September is half dry, the seeds are as fine as mustard seeds and the color is yellow and red, and the oil is like stubble oil."

The main components are oil, protein, flavonoids, polyphenols, Sterols, etc. Perilla seeds are rich in oil, and perilla seed oil is the vegetable oil with the highest linoleic acid content, generally not less than 60%. The oil content of perilla seeds is 30% to 45%, of which the content of unsaturated fatty acids is up to More than 90%. In addition, there are large number of bioactive components such as flavonoids and phenolic acids in perilla seeds.

It has developed potential and has been used in health food, medicine and other fields. In recent years, researches on the biological activities of perilla seeds mainly include lowering blood lipids, anti-aging, improving memory, antibacterial and anti-inflammatory, anti-oxidation, anti-cancer, immune regulation, etc.

Perilla seeds are rich in oil, protein, polyphenols, vitamin E and a variety of mineral elements.

Scholars at home and abroad have done a lot of pharmacological research on perilla in recent years, but most of them focus on the medicinal mechanism of perilla leaves, and less attention has been paid to perilla seeds. The ingredients of traditional Chinese medicine preparations such as Huoxiangzhengqi series, children's Qingfei series, Ganmao Qingre granules, and Shensu series, and the development of medicinal products of perilla seeds need to be strengthened.
