Modern research shows that perilla is rich in alpha-linolenic acid, volatile oils and flavonoids, which have significant benefits for respiratory system and cardiovascular health. The following will systematically analyze the value of perilla from three aspects: traditional application, pharmacological effects and modern research.

#### **Second paragraph: Traditional application and antitussive and asthmatic effects**

Su Zi returns in the theory of traditional Chinese medicineLung, large intestine meridian, often used to treat cough, asthma and phlegm symptoms. Classic prescriptions such asSanzi Yangqin Soup(Perilla seeds, white mustard seeds, radish seeds) take advantage of their properties of lowering qi and resolving phlegm.

Studies have shown that daily intake of 10g perilla powder can significantly improve dyslipidemia (see Table 1).

research indicators	Perilla group (10g/day)	control group
total cholesterol	12% reduction	No change
LDL	15% reduction	No change
Triglycerides	18% reduction	No change

#### **Paragraph 4: Antioxidation and immune regulation**

Su Zizhong'sflavonoids(such as luteolin) has strong antioxidant activity, can scavenge free radicals and delay cell aging. Animal experiments show that perilla extract can increase superoxide dismutase (SOD) activity and enhance the body's anti-stress ability. In addition, its polysaccharide component can stimulate macrophage proliferation and indirectly enhance immunity, making it suitable for daily conditioning of sub-healthy people.
