Perilla (Latin: Perilla frutescens (L.) Britton), also known as Perilla, it is distributed in Hubei, Jiangsu, Hunan, Zhejiang, Anhui, Henan, Gansu and other regions. It likes warm and humid climate, and has strong resistance to humidity, waterlogging and drought. It is widely cultivated in China for medicinal and spice use.

Perilla Seed Extract is extracted from Perilla Seed, and rosmarinic acid is a component of Perilla Seed Extract, which is a natural multifunctional phenolic acid compound. Rosmarinic acid has antibacterial, anti-inflammatory, antiviral, anti-tumor, anti-allergic, anti-oxidation, anti-thrombotic, anti-platelet aggregation, anti-radiation and immunosuppressive effects. Rosmarinic acid has anti-anxiety effect on the nervous system and protective effect on cell damage, and is widely used in medicine, food, cosmetics and other aspects.

1. Inhibiting bacteria: Rosmarinic acid from Perilla Seed Extract can significantly inhibit subtilis, luteococcus and Escherichia coli.
2. Inhibition of fungi: The inhibitory activity of rosmarinic acid on mycelial growth and spore germination of different plant pathogenic fungi.
3. Inhibiting mold: Rorosemary acid in Perilla Seed Extract can inhibit phytophthora and mold spores causing soil-borne diseases, effectively reducing the germination of zoospores.
4. Anti-nephritis effect: Rosmarinic acid can inhibit mesangial cell proliferation and glomerular expansion.
5. Anti-hepatitis effect: Rosmarinic acid can reduce lipopolysaccharide (LPS) -induced liver injury and significantly inhibit the increase of plasma transaminase levels, proving that the liver protective effect of rosmarinic acid is produced by clearing or reducing superoxide or nitrite oxide rather than by inhibiting TNF-α.
6. Anti-pneumonia effect: Rorosemary acid inhibits lung injury characterized by neutrophil retention and interstitial edema induced by diesel exhaust particles.
7. Anti-arthritic effect: Rosmarinic acid can inhibit collagen-induced arthritis, significantly reducing the number of arthritis and affected joints.
