Perilla (Deulkkae)

Health Benefits

Omega-3 and heart health. Perilla seed oil is very high in alpha-linolenic acid (18:3), making it a key plant-based source of omega-3. ALA is partly converted in the body to EPA and DHA, supporting cardiovascular and brain health, and it serves as an alternative to fish oil in plant-forward diets.

Anti-inflammatory and liver protection. Animal studies have shown that perilla seed oil has anti-inflammatory activity that eases chronic inflammation along the gut-liver axis. The combined action of alpha-linolenic acid and rosmarinic acid is proposed as the mechanism, and the oil shows potential as a supportive dietary aid for non-alcoholic fatty liver disease.

Functional food. A comprehensive review of perilla seed nutrition and bioactivity highlighted its potential as a multipurpose functional food, driven by active compounds including alpha-linolenic acid, rosmarinic acid, and luteolin. Beyond its place as a traditional Korean ingredient, it is gaining attention as an emerging material in the global functional-food market.

Effect of ALA supplementation on cardiovascular risk factors (meta-analysis). A 2023 meta-analysis pooling 19 RCTs and 1,183 participants found that alpha-linolenic acid (ALA) supplementation from sources such as perilla and flaxseed significantly lowered systolic blood pressure, triglycerides, C-reactive protein, and tumor necrosis factor-alpha in obese and overweight groups. This strengthens the clinical case for plant-based omega-3 as a supportive therapy for metabolic syndrome.

Nutrition

• Alpha-linolenic acid (omega-3) (Abundant in perilla oil) — Heart health, anti-inflammatory, brain function
• Rosmarinic acid (Found in the leaves) — Antioxidant and anti-inflammatory

Pairings

○ Raw fish, raw meat, and crab — Perilla leaves cut the fishy and gamy notes of raw fish or meat and help neutralize toxins from fish and shellfish, a benefit recognized in both the Donguibogam (a classic Korean medical text) and modern pharmacology. This is the medicinal basis behind the Korean custom of wrapping a slice of raw fish in a perilla leaf.

○ Pork belly and pork — Wrapping pork in a perilla leaf (kkaennip-ssam) is a Korean classic. The alpha-linolenic acid in perilla balances the saturated fat of pork, giving the pairing a nutritional logic that lightens a heavy meal.

○ Seaweed — Perilla seaweed soup (deulkkae miyeok-guk) is a classic postpartum recovery dish in Korea. The minerals in seaweed, the omega-3 in perilla, and chlorophyll come together in one bowl to supply the nutrients needed for recovery after childbirth.

○ Mushrooms and bean sprouts — Adding mushrooms and bean sprouts to perilla noodle soup or perilla stew makes a balanced bowl of protein, omega-3, and fiber. The nutty richness of perilla rounds out the plainness of the vegetables for deeper flavor.

○ Steamed rice — Drizzling perilla oil over bibimbap, in place of soy sauce and sesame oil, makes a meal that helps prevent constipation. The fiber and alpha-linolenic acid in perilla stimulate the bowels and support regularity naturally.

△ High-heat cooking — Omega-3s break down under heat, so perilla oil is best used in dressings, in seasoned vegetable dishes, or drizzled on just before a dish is finished. Using it for frying or long stir-frying not only destroys the nutrients but can generate harmful oxidation byproducts.

△ Patients on blood thinners — Perilla oil and ground perilla seeds are rich in omega-3s with anti-clotting effects, so patients on anticoagulants such as warfarin should avoid large amounts. Normal dietary use poses little concern, but supplement-level doses call for medical advice.
