Perrilla frutescens, commonly referred to as perilla, is a food and traditional medicine in Asian countries, particularly Japan and China. A member of the mint family, the leaves are used in Chinese herbal medicine for symptoms of asthma and cough and contain calcium, iron, and vitamin C. Its seeds support healthy immune function and are a rich source of omega-3 alpha-linolenic acid (ALA).
Benefits of Perilla Frutescens
Research has found that perilla is effective at fighting harmful organisms, especially in the mouth.  Japan’s Asahi University School of Dentistry tested the action of perilla seed and found that it contains a compound, Luteolin, which may help reduce cavities and lessen the occurrence of some dental concerns. 
Like many botanicals, perilla is a great source of antioxidants. Also known as nature’s answer to aging, antioxidants help lessen the systemic damage caused by free radicals. Japanese research suggests that perilla’s antioxidant action supports healthy circulation and has a positive effect on cholesterol.  
Perilla contains rosmarinic acid, which is known to resist redness and swelling. If you have allergies, you’ve liked experienced allergic rhinitis, an irritation of the airways. Perilla leaf extract has been reported to promote a healthy response when such irritations flare up. 
Supplementing With Perilla
The benefits of therapeutic plants are available through many forms of ingestion. Sometimes a tea is made from the leaves, sometimes extracts can offer much more potent and concentrated servings of the active, beneficial compounds.
