Perilla frutescens, commonly known as perilla, is an aromatic herb in the mint family. This versatile plant has distinctive leaves and a rich history of culinary and medicinal use across Asia.

Perilla Overview

Perilla is an annual herb native to Southeast Asia. It grows 1-3 feet tall with broad, serrated leaves that can be green or purple. The plant belongs to the Lamiaceae family, which includes other aromatic herbs like basil and mint. Perilla has several common names, including shiso, beefsteak plant, and Chinese basil.

Perilla leaves have a unique flavor profile, combining notes of mint, basil, and citrus. The leaves are often described as having a peppery or anise-like taste. Both the leaves and seeds of perilla are edible and used in various Asian cuisines.

Cultivation and Varieties

Perilla is easy to cultivate and grows well in temperate climates. It prefers full sun to partial shade and well-draining soil. The plant is frost-sensitive and typically grown as an annual outside its native range.

Several varieties of perilla exist, each with distinct characteristics:

  • Green Perilla: Most common variety, used in Korean cuisine as kkaennip
  • Red Perilla: Purple leaves, popular in Japanese cuisine as shiso
  • Curly Perilla: Frilly leaves, often used as a garnish

Perilla is valued for its ornamental qualities and is sometimes grown as a decorative plant. It self-seeds readily, which can lead to it becoming invasive in some regions if not properly managed.

Perilla leaves offer numerous health benefits due to their rich nutrient profile and bioactive compounds. These leaves contain vitamins, minerals, and phytochemicals that contribute to various aspects of well-being.

Anti-Inflammatory and Antioxidant Effects

Perilla leaves are packed with powerful antioxidants, including rosmarinic acid, luteolin, and apigenin. These compounds help protect cells from oxidative stress and reduce inflammation in the body. Rosmarinic acid, in particular, has shown strong anti-inflammatory properties in studies.

The antioxidants in perilla leaves may help prevent chronic diseases associated with oxidative damage. Regular consumption of these leaves could potentially lower the risk of certain cancers and neurodegenerative disorders.

Perilla’s anti-inflammatory effects may also benefit skin health. Topical application of perilla leaf extracts has been found to soothe irritated skin and reduce inflammation.

Respiratory and Digestive Health

Perilla leaves have traditionally been used to support respiratory health. The anti-inflammatory properties of perilla may help alleviate symptoms of asthma and allergic reactions. Some studies suggest that perilla extract can reduce airway inflammation and improve lung function.

In terms of digestive health, perilla leaves may aid in preventing and treating gastrointestinal issues. The fiber content in these leaves supports healthy digestion and promotes regular bowel movements. Perilla also contains compounds that may help reduce stomach acid and protect against ulcers.

The leaves’ antimicrobial properties could potentially help combat harmful bacteria in the digestive tract, promoting a healthier gut microbiome.

Cardiovascular and Immune Support

Perilla leaves may contribute to heart health through their omega-3 fatty acid content, particularly alpha-linolenic acid (ALA). ALA has been associated with a reduced risk of cardiovascular diseases. The leaves’ antioxidants may also help lower blood pressure and improve cholesterol levels.

The immune-boosting properties of perilla leaves stem from their high vitamin C content and other antioxidants. These nutrients support the body’s defense mechanisms against infections and diseases. Regular consumption of perilla leaves may help strengthen the immune system and increase resistance to common illnesses.

Perilla’s anti-inflammatory effects may also indirectly support immune function by reducing chronic inflammation, which can compromise immune responses.
