Perilla
Perilla is a leafy herb from East and South Asia rich in polyphenols and, in seed form, omega-3 fatty acids. Commonly used in Korean and Japanese cuisine, it has mild antioxidant and anti-inflammatory properties supported by laboratory evidence. Nutritional contributions from typical culinary portions are modest but include meaningful amounts of vitamins A and C, calcium, and iron.
Also known as: shiso, kkaennip, perilla leaf, perilla leaves, Perilla frutescens, Korean mint, beefsteak plant, zi su

Perilla (Perilla frutescens), also called shiso or Korean mint, is an aromatic leaf used across East Asian cuisines as a garnish, seasoning, or wrap. The plant is native to South and Southeast Asia, with a long history of cultivation in China, Korea, and Japan. It appears in Korean banchan side dishes, Japanese sushi accompaniments, and traditional medicine preparations throughout the region. The herb has a distinctive anise-like or minty flavor profile and is typically consumed fresh, though dried and oil forms exist.
Perilla leaves contain polyphenolic compounds including rosmarinic acid and luteolin, which have demonstrated antioxidant activity in laboratory studies. The seeds are notably higher in alpha-linolenic acid (ALA), an omega-3 precursor, comprising roughly 50–60% of seed oil by weight. Fresh perilla leaves also provide meaningful amounts of vitamins A and C, calcium, and iron relative to their weight. When consumed as a culinary herb in typical garnish amounts, the absolute contribution of these nutrients to daily intake is small.
Anti-inflammatory and Antioxidant Activity
Rosmarinic acid and other phenolic compounds in perilla exhibit antioxidant and anti-inflammatory properties in cell and animal models. However, human clinical trials demonstrating systemic anti-inflammatory effects from culinary perilla consumption are sparse. The polyphenol content is real but modest at culinary portions; perilla should not be relied upon as a primary anti-inflammatory intervention. Regular consumption as a seasoning or garnish contributes phytonutrients as part of a varied diet.
Safety and Consumption Guidance
Perilla is generally recognized as safe for culinary use at typical food portions. Perilla ketone, a naturally occurring compound in some perilla varieties, has caused pulmonary toxicity in grazing livestock at high exposures; culinary consumption by humans at normal food amounts does not present this concern. Individual allergic reactions are possible but uncommon. Perilla seed oil supplements, when taken in concentrated doses, may theoretically interact with anticoagulant medications due to high ALA content; consultation with a healthcare provider is prudent before supplementation. Culinary use of the fresh leaf poses no such concern.
Frequently Asked Questions
Is perilla the same as basil or mint?
Perilla is botanically distinct from both basil and mint, though all three belong to the Lamiaceae family. Perilla (Perilla frutescens) has a unique flavor—often described as anise-like or minty—and a distinct nutritional profile. It is primarily used in Korean and Japanese cuisines, whereas basil is common in European and Southeast Asian cooking and mint is used globally.
Does perilla contain omega-3 fatty acids?
Perilla seeds are exceptionally rich in alpha-linolenic acid (ALA), an omega-3 precursor, making up roughly 50–60% of perilla seed oil. However, typical culinary use of the fresh leaf provides negligible ALA; only concentrated seed oil or supplements deliver meaningful omega-3 content.
Is perilla safe for people taking blood thinners?
Culinary portions of fresh perilla leaf are considered safe. Perilla seed oil supplements taken in high doses may theoretically interact with anticoagulant medications due to their high ALA content. Consult a healthcare provider before taking perilla oil supplements if you use blood thinners.
What is perilla ketone and is it dangerous?
Perilla ketone is a naturally occurring compound found in some perilla varieties that has caused pulmonary toxicity in grazing livestock exposed to large quantities. At the trace levels present in culinary perilla, it poses no known risk to humans consuming the herb as a food. Concerns about perilla ketone relate specifically to livestock grazing scenarios, not to normal human culinary use.
