Overview

Perilla frutescens (L.) Britton is an annual in the Lamiaceae — the mint family, and it looks it: square stems, opposite leaves in pairs, small two-lipped flowers in slim spikes. It grows fast and tall for a herb, 60 to 120 cm in a season, with broad serrated leaves that may be green, deep purple-red, or green on top and purple beneath depending on the variety.

It is native to East and Southeast Asia and has been cultivated for well over a thousand years in China, Japan, Korea, Vietnam and the northeastern Indian hills. Two quite different crops come from it. In Japan, Vietnam and China it is grown as a leaf herb, picked young and used raw. In Korea and parts of northern India it is also grown as an oilseed — deulkkae, whose seeds are pressed for cooking oil or ground into soups. The leaf crop and the seed crop are usually different cultivars of the same species.

Perilla has also naturalised across much of the eastern and midwestern United States, where it is a common weed of fencerows, woodland edges and pastures under the names "beefsteak plant" and "purple mint." That naturalised American population is the source of the toxicity problem described below; it is not the same material as the cultivated food crop.

Names and Identification

The sesame trap. Korean kkaennip is routinely translated as "sesame leaf" on restaurant menus and grocery packaging in the West. It is not sesame. Sesame is Sesamum indicum, a completely unrelated plant in the Pedaliaceae, and its leaves are not eaten. The confusion comes from Korean usage: chamkkae ("true kkae") is sesame, deulkkae ("wild kkae") is perilla, and kkaennip is literally "kkae leaf." For people avoiding sesame because of an allergy, this means a packet of Korean "sesame leaves" is perilla, not sesame (perilla itself can be an allergen, as the Cautions section notes) — and perilla oil is quite different in flavour from the nutty toasted taste of sesame oil.

The ornamental trap. Deep-purple perilla is sold in Western garden centres as a bedding plant, sometimes labelled "beefsteak plant" and sometimes confused with coleus, which it superficially resembles. Ornamental nursery stock is grown as a decorative and may carry pesticides not permitted on food crops, so it is not food-grade material.

Distinguishing the culinary types. Japanese green shiso has strongly crinkled, saw-toothed leaves and a bright, unmistakable aroma with notes of cumin, cinnamon and citrus. Red shiso has the same crinkle but is purple through and through, with a duller aroma — its job is colour and pickling. Vietnamese tía tô is typically green on the upper surface and purple underneath, less crinkled, and noticeably more anise-like. Korean kkaennip leaves are much larger, flatter, rounder and softer, with a milder, greener flavour; they are built to be a wrapper. They are not interchangeable in cooking.

Safety Flag: Chemotypes and Perilla Ketone

This is the single most important thing on this page, and it is very poorly known outside veterinary medicine.

Perilla frutescens is a textbook chemotype species. Its essential-oil composition is controlled by a small number of genes and falls into discrete, sharply different types — plants that look almost identical can produce completely different dominant compounds. Botanists name the chemotypes after the compound that dominates:

The chemotype letters follow the 1995 genetic study of the plant's essential-oil variants (Yuba 1995); the variety and seed-crop entries follow a 2016 survey of perilla in China (Wei 2016) and a 2009 analysis of Korean perilla leaf (Seo & Baek 2009).

What perilla ketone does. Perilla ketone is a substituted furan — chemically, 3-furyl isoamyl ketone. Furans are generally harmless until an enzyme opens the ring. In the lung, the club cells lining the small airways are unusually rich in cytochrome P450 monooxygenases, and those enzymes convert perilla ketone into a highly reactive intermediate that attacks the surrounding cells. The lung, in other words, poisons itself in the act of processing the compound. The result in cattle is acute pulmonary oedema and emphysema — a syndrome sometimes called "perilla mint toxicosis," and one of the recognised causes of acute bovine pulmonary emphysema.

The chemistry was pinned down in 1977, when a group publishing in Science isolated perilla ketone from the mint plant and identified it as a potent lung toxin. Follow-up work in the 1980s established which species are susceptible and produced in-vivo evidence that the lung monooxygenase system is required for the damage, and field reports documented cattle deaths in Tennessee and neighbouring states.

The pattern on American farms is consistent and seasonal: perilla grows in shady fencerows and around barns; in late summer, when pasture is short and the plants are flowering and seeding, cattle browse it; and the animals are found dead or in severe respiratory distress within a day or two. It is a real and recurring agricultural problem, not a laboratory curiosity.

What the chemotype research means in practice:

1. Grocery perilla is not all one chemotype. Japanese shiso (var. crispa) is mainly the perillaldehyde type (Wei 2016). Korean perilla leaf is not: in a 2009 analysis, perilla ketone made up 81–95% of its volatile compounds, depending on the extraction method, with egomaketone and isoegomaketone among its characteristic aroma compounds (Seo & Baek 2009). Millions of people eat these leaves daily. There is no evidence of lung toxicity from the food crop.
2. Wild North American perilla is not the same material as shiso. Naturalised American populations are the ones linked to cattle poisoning, and chemotype cannot be told by looking or, reliably, by smell.
3. Perilla essential oil is the concentrated form of the concern. Essential oil is the concentrated volatile fraction, which is precisely where the chemotype difference lives. Commercial perilla essential oil is sold for aromatherapy and is not standardised for internal use.
4. Perilla seed oil is a separate product and is not implicated. Pressed seed oil is a fatty oil — triglycerides — not the volatile essential oil. Perilla ketone is not a meaningful component of cold-pressed culinary seed oil.

Traditional Use

Chinese medicine has used perilla for a very long time and splits it into three separate drugs. Zi su ye (the leaf) is classified as acrid and warm, used for the earliest stage of a wind-cold common cold — the stage of chills, stuffy nose and no sweating — and classically for seafood and crab poisoning, which is the traditional rationale behind serving shiso with raw fish. Zi su geng (the stem) is used to settle nausea in pregnancy and to move stagnant qi in the chest. Zi su zi (the seed, formally Perillae Fructus) is used quite differently — to "descend qi," loosen phlegm and quiet a wheezy cough, and it appears in the classical formula San Zi Yang Qin Tang.

Japanese Kampo inherited these uses. Perilla leaf (so-yo) is a component of hange-koboku-to, a formula prescribed for the sensation of a lump in the throat with no physical cause — the symptom Western medicine calls globus — and for anxiety-linked chest tightness. It also appears in koso-san, a gentle cold formula.

In Vietnam, tía tô is the household cold remedy: leaves torn into hot rice porridge (cháo tía tô) with ginger and spring onion, eaten to raise a sweat at the first sign of chills. In Korea, perilla is food first, but perilla seed powder is folk-credited with easing coughs and, in older practice, with helping a mother's milk supply.

None of this is proof of anything. It is a record of what people did, and it is a useful guide to where a researcher might look — nothing more.

Active Compounds

Perillaldehyde — the defining aroma compound of perillaldehyde-type perilla such as Japanese shiso, often 50–60% or more of the leaf essential oil. It is the smell of shiso. It also has a curious derivative: perillartine (the oxime of perillaldehyde), which is roughly two thousand times sweeter than sucrose and has been used as a sweetener in Japan.

Rosmarinic acid — the main water-soluble polyphenol of the leaf, and the compound behind most of perilla's tested anti-allergic activity. It is not unique to perilla: rosemary, lemon balm, sage and Vietnamese balm all contain it, sometimes in higher amounts. Any claim about "perilla's" anti-allergy effect is really a claim about rosmarinic acid.

Luteolin, apigenin and their glycosides — flavones with the usual in-vitro anti-inflammatory profile.

Anthocyanins, chiefly shisonin (a malonylshisonin-type cyanidin glycoside) — the red pigment of akajiso. Like all anthocyanins it is pH-sensitive: dull purple in neutral conditions, brilliant magenta-red in acid. That reaction is not chemistry trivia; it is exactly why salted red shiso packed with sour ume plums produces the electric red of umeboshi, and why shiso juice turns vivid the moment you add citric acid or lemon.

Alpha-linolenic acid (ALA) — the dominant fatty acid of the seed, discussed in its own section below.

Perilla ketone, egomaketone, isoegomaketone — the furanoketones of the perilla-ketone chemotype, which includes Korean perilla leaf (Seo & Baek 2009). The safety section covers them.

Perilla Seed Oil and Alpha-Linolenic Acid

This is the most solid, most checkable nutritional fact about the plant.

Perilla seed oil typically contains 55–60% alpha-linolenic acid (ALA, an 18-carbon omega-3 fatty acid), with roughly 14% linoleic acid and 13–16% oleic acid. For comparison, flaxseed oil — the plant omega-3 everyone has heard of — usually runs about 50–58% alpha-linolenic acid. Perilla generally edges it out, and the two are the richest widely available plant sources by a wide margin. Rapeseed oil is around 9%, soybean oil around 7%, walnut oil around 10%.

The honest caveat, and it matters. Alpha-linolenic acid is not eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA), the long-chain omega-3s that most of the cardiovascular and brain research is actually about. Your body can elongate alpha-linolenic acid into eicosapentaenoic acid and docosahexaenoic acid, but the conversion is poor: commonly cited figures are around 5–8% of alpha-linolenic acid reaching eicosapentaenoic acid and well under 1% reaching docosahexaenoic acid, with the rate lower in men than in women. So perilla oil raises alpha-linolenic acid intake substantially and docosahexaenoic acid very little. For people who eat no fish, algal oil is a direct source of docosahexaenoic acid; perilla oil is not a substitute. What perilla oil does offer is a way to displace omega-6-heavy seed oils in the overall balance of dietary fats — and, in the trials below, it measurably raised the alpha-linolenic acid content of participants' cell membranes.

Handling and storage. With three double bonds on most of its fatty acids, perilla oil oxidises fast. It goes rancid at room temperature in weeks and is not suited to frying; it is usually sold in small dark bottles, and the common storage guidance is refrigeration once opened and use within a couple of months. Rancid oil is not neutral — it delivers oxidised lipids. Korean deulgireum (toasted perilla seed oil) is used as a finishing oil, drizzled over vegetables at the end.

Allergy and Rhinitis: The Human Trials

Mechanism. Rosmarinic acid suppresses allergic antibody responses and dampens the recruitment of neutrophils and eosinophils in animal models of allergic inflammation. That is the rationale for testing it in hay fever.

The human trial. One randomised, double-blind, placebo-controlled study tested a rosmarinic-acid-enriched perilla extract in adults with mild seasonal allergic rhinoconjunctivitis, over 21 days. Participants received 200 mg of rosmarinic acid, 50 mg, or placebo. Compared with placebo, the extract significantly increased responder rates for itchy nose, watery eyes, itchy eyes and total symptom score, and significantly reduced neutrophil and eosinophil counts in nasal lavage fluid. No adverse events were reported and routine blood tests were normal.

Now the size. The three groups were ten, nine and ten people. Twenty-nine participants in total, for three weeks, in mild disease. That is a pilot study. The reduction in nasal inflammatory cells is genuinely interesting because it is an objective measurement rather than a diary score, and it points at a real mechanism. But a positive result in twenty-nine people has not been replicated at a size that would change practice, and it is now two decades old. In short: plausible, encouraging, unconfirmed. Perilla extract is not an antihistamine, and this pilot trial did not test it as a replacement for one.

Bone and Brain: Two Small Oil Trials

Two Japanese randomised trials of perilla seed oil are worth reporting accurately, because they are the strongest human data the plant has and they are still modest.

Bone. A 12-month randomised, double-blind, placebo-controlled trial gave 52 healthy Japanese adults (mean age 54) either 7.0 mL of perilla seed oil or 7.0 mL of olive oil daily. After a year, the perilla group showed a significant increase in calcaneal (heel-bone) ultrasound density expressed as percentage of the young adult mean, and a significant fall in serum TRACP-5b, a marker of bone resorption. Bone alkaline phosphatase, a marker of bone formation, did not change — so the mechanism, if real, is slowed breakdown rather than increased building. Red-cell membrane alpha-linolenic acid rose and an antioxidant-balance ratio improved, confirming the oil was actually absorbed.

What to make of it: 52 people, one site, and heel ultrasound is a screening surrogate, not the DXA hip-and-spine scan that defines osteoporosis. A twelve-month duration is respectable. Call it a promising signal that needs a bigger trial with real bone-density endpoints and fracture follow-up.

Cognition. A second 12-month randomised, double-blind trial in 49 healthy elderly Japanese adults compared perilla seed oil alone (1.47 mL a day, 0.88 g of alpha-linolenic acid) with the same oil plus nobiletin-rich ponkan citrus powder. At the end, the combination group had significantly higher cognitive index scores than the oil-only group. There was no placebo arm, so the result concerns the added ponkan powder, and the oil's own effect cannot be separated out. It cannot support a claim that perilla oil improves memory.

Colds, Cough, and the Kampo Uses

What is claimed. Perilla leaf for the first day of a cold; perilla seed for a phlegmy cough; hange-koboku-to for the lump-in-the-throat sensation.

What is known. Perillaldehyde has antibacterial and antifungal activity in culture, and perilla extracts show anti-inflammatory effects on airway cells in the laboratory. Kampo formulas containing perilla have been studied in Japan for globus sensation and for functional dyspepsia, but almost always as whole multi-herb formulas, often without placebo control, and usually in small numbers. No controlled trial shows that perilla leaf shortens a cold or reduces cough.

The sashimi question. The traditional claim that shiso protects against food poisoning from raw fish is charming and partly grounded — perillaldehyde does inhibit bacterial growth in a dish. But the amount of leaf on a sashimi plate, in contact with the fish for a few minutes, is nowhere near enough to sterilise anything. The green leaf under sashimi is a flavour element and a garnish, not a food-safety measure.

Culinary Use

Perilla is a major food across four cuisines that each use it completely differently. This is where the plant genuinely earns its place.

Japan — shiso, two colours, four forms. Aojiso (green shiso) is the aromatic one. It is shredded fine over sashimi and cold noodles, wrapped whole around fish or chicken before grilling, folded into rice balls, laid over umeboshi in a maki roll, and — best of all — battered on one side only and deep-fried as tempura, so the leaf shows green through a lace of batter. It has an affinity for cold soba dipping sauce and for tomato, which is why it turns up in Japanese-Italian cooking. Akajiso (red shiso) is a colouring and preserving agent: massaged with salt and packed with ume plums, it turns umeboshi their characteristic red; dried and ground with salt it becomes yukari furikake; and simmered with sugar and citric acid it makes shiso juice, the electric-magenta summer drink whose colour change on adding acid delights every child who watches it. Two more forms garnish sashimi plates: mejiso, the tiny sprouts, and hojiso, the flower spikes, which are stripped into soy sauce with the back of a chopstick.

Korea — kkaennip as wrapper and pickle. The broad soft leaf is a ssam wrapper: a piece of grilled pork belly, a smear of ssamjang, a sliver of raw garlic, folded up and eaten in one bite. It is also the basis of kkaennip jangajji — leaves stacked in a jar with soy sauce, garlic, chilli flakes and sesame, then peeled off one at a time over rice, a side dish that is genuinely addictive. Battered and pan-fried as kkaennip jeon, sometimes stuffed with seasoned pork, it becomes a main dish. Separately, the ground seed (deulkkae garu) is a Korean pantry staple: stirred into gamjatang pork-bone stew, folded into blanched vegetable namul, and used to make deulkkae kalguksu, a pale, nutty, almost creamy noodle soup that contains no dairy at all.

Vietnam — tía tô on the herb plate. It is one of the standard rau thơm served raw alongside noodle soups and grilled meats — with bún riêu, bún bò Huế, bún chả, and rolled into fresh spring rolls next to fish mint and Vietnamese balm. Its anise-menthol edge is more assertive than Japanese shiso, and it holds up against strong fermented dipping sauces. It is also torn into hot rice congee as the household cold remedy, and eaten with snails and with bò lá lốt.

China. Zi su leaves are cooked with crab, clams and freshwater fish, both for flavour and on the traditional reasoning that a warm herb balances a cold food. Fried perilla leaf appears in Hunan and Guizhou cooking.

Buying, storing, growing. Fresh perilla wilts fast. Stiff, unblemished leaves keep best; stood in a glass of water like a bouquet, loosely bagged and refrigerated, they last three or four days. Korean kkaennip is usually sold in stacked plastic packs and keeps a little longer. Perilla is one of the easiest herbs to grow from seed in a warm summer — the seed needs light to germinate, so it is sown shallowly — and it self-seeds enthusiastically, which is exactly how it became an American weed; a pot contains that spread.

Substitutions. There is no true substitute for shiso. A mixture of Thai basil, mint and a little tarragon gets you into the right neighbourhood for aroma. Nothing substitutes for kkaennip as a wrapper except a large butter-lettuce leaf, which brings no flavour at all. Red and green shiso are not interchangeable: red is for colour and pickling, green is for aroma.

Forms and Preparations

• Fresh leaf — the primary culinary form. Green shiso, red shiso, Vietnamese tía tô and Korean kkaennip are distinct products.
• Salted red shiso — sold in vacuum packs for pickling; also the ground yukari seasoning.
• Dried leaf and leaf tea — much of the aroma is lost; the rosmarinic acid survives.
• Perilla seed (deulkkae) and ground seed powder — a Korean staple ingredient, sold whole or ground. Ground seed goes rancid quickly and keeps best in small amounts, refrigerated.
• Perilla seed oil — two versions. Cold-pressed (pale, mild, for dressings and supplements) and toasted (Korean deulgireum, dark and nutty, a finishing oil). Neither suits frying.
• Perilla leaf extract capsules — usually standardised to rosmarinic acid; this is the form used in the allergy trial.
• Perilla essential oil — the concentrated volatile fraction, sold for aromatherapy. Not standardised for internal use — this is where the chemotype issue lives.
• Kampo and TCM formulas — hange-koboku-to, koso-san, San Zi Yang Qin Tang, prescribed as whole formulas.

Dosage

• Fresh leaf as food: no upper limit has been set. Korean and Japanese diners commonly eat 10–30 g a day.
• Perilla seed oil: the 12-month bone trial used 7.0 mL per day. General alpha-linolenic acid guidance gives a comparison — most dietary bodies suggest roughly 1.1 g/day of alpha-linolenic acid for women and 1.6 g/day for men, and a single teaspoon (about 5 mL) of perilla oil supplies roughly 2.5–3 g, comfortably above either figure.
• Rosmarinic acid extract: the allergy trial used 50 mg or 200 mg a day of a perilla extract enriched for rosmarinic acid for 21 days. In that small study (29 people with mild seasonal allergies) the extract improved itchy nose, watery and itchy eyes and total symptoms compared with placebo; the published summary reports the two doses together.
• Dried leaf in decoction (TCM): zi su ye is commonly prescribed at roughly 5–10 g per day and zi su zi (seed) at roughly 3–10 g, always as part of a formula. These are traditional prescribing ranges, not doses validated against a diagnosis.
• Perilla essential oil: no internal dose has been established; it is sold for aromatherapy, not for ingestion.

Cautions and Contraindications

• Wild perilla in North America. Naturalised "purple mint" and "beefsteak plant" populations may be perilla-ketone chemotypes. The compound is a documented lung toxin in livestock, and foraged wild plants are not the cultivated food crop.
• Perilla essential oil. The same concern, concentrated. Aromatherapy oils are not standardised for chemotype and are not food.
• Perillaldehyde is a contact sensitiser. It belongs to the family of fragrance aldehydes that cause allergic contact dermatitis, and hand dermatitis has been described in people who handle large quantities of the fresh leaf.
• Perilla itself can be an allergen. Allergic reactions to perilla leaf and seed have been reported, mostly from countries where it is eaten daily and in quantity. It is not a common allergen in the West, but it is not a non-allergen either.
• Rancid oil is a real risk. Perilla seed oil oxidises faster than almost any other culinary oil. Oil that smells of paint or old fish has oxidised; small bottles, refrigeration after opening and no frying are the usual ways of limiting it.
• Bleeding risk is theoretical rather than demonstrated. Omega-3 fats have mild antiplatelet effects, and the standard advice is to mention any high-dose omega-3 supplement to a surgeon or to a clinician managing warfarin, apixaban or clopidogrel. That said, alpha-linolenic acid has a much weaker antiplatelet effect than the eicosapentaenoic acid and docosahexaenoic acid in fish oil, and clinically significant bleeding attributable to culinary perilla oil has not been demonstrated.
• The alpha-linolenic acid and prostate cancer question. An older body of observational research suggested a weak association between high alpha-linolenic acid intake and prostate cancer risk. Later and larger analyses have been inconsistent, and the association is not considered established. The question is most relevant to people taking high-dose alpha-linolenic acid supplements long term who have a strong family history; the research does not point against perilla as a food.
• Pregnancy and breastfeeding. Perilla leaf in food amounts is traditional across East Asia, including in Chinese formulas specifically used for pregnancy nausea. Concentrated extracts and essential oil have no safety data in pregnancy.
• Drug interactions. Poorly studied. No clinically important interaction has been established for perilla leaf; the omega-3 note above is the practical one.
