Perilla seed is the dry and mature fruit of Perilla perillata, a plant of the Labiatae family. It is warm in nature and pungent in taste. It belongs to the lung and large intestine meridian. It hasLowers qi and resolves phlegm, relieves cough and asthma, moistens intestines and relieves constipationand other effects. Its core functions focus on the respiratory and digestive systems. Modern research also shows that it is rich in active ingredients such as alpha-linolenic acid, which has certain auxiliary effects on cardiovascular health. The following will start from three aspects: traditional application, modern research and precautions, and analyze its value clearly.

---### **Traditional application: relieving cough, reducing phlegm and laxative**

Perilla seeds have long been recorded in traditional Chinese medicine classics, and the "Compendium of Materia Medica" states that it "maintains the lowering of Qi, removing cold and warming".Relieves cough and asthmaOn the other hand, it is often used in combination with almonds and tangerine peel to treat coughs and asthma caused by phlegm and qi.Soothing and laxativeIt is often used together with hemp seeds to improve intestinal dryness and constipation.

The traditional usage is mainly to decoct and take it, and the daily dosage is 3 to 9 grams.

---### **Modern Research: Active Ingredients and Health Potential**

In recent years, studies have found that Perilla frutescensalpha-linolenic acid(Omega-3 fatty acids) content is as high as 50%~60%, which can help regulate blood lipids (see table). In addition, its volatile oil components such as perillaldehyde have anti-inflammatory and antioxidant effects, and animal experiments have shown that it can improve chronic bronchitis models. However, it should be noted that most of these studies are in the preliminary stage and the clinical evidence still needs to be improved.

Ingredients	Content (%)	Potential role
alpha-linolenic acid	50~60	Regulate blood lipids, anti-inflammatory
protein	about 20	Nutritional supplements
volatile oil	1~3	Antibacterial, antitussive

---### **Usage Precautions and Taboos**

Although perilla seed is a product of the same origin as medicine and food, itUse with caution in those with chronic cough due to yin deficiency and slippery diarrhea caused by spleen deficiency., overdose may cause diarrhea.

---### **Summary: Reasonable application to bring out value**

Perilla seeds combine traditional wisdom with modern science to play an important role in respiratory and digestive system health. Treatment needs to be based on syndrome differentiation when using it, and avoid blind pursuit of efficacy. Future research may further clarify the mechanism of action of its active ingredients and provide a basis for the development of functional foods.
