Uses and Pharmacology

Antioxidant properties of perilla leaf and seed extracts, as well as individual chemical constituents, have been extensively studied in experimental models,  with limited therapeutic applications evaluated.

Anti-inflammatory and antiallergic effects

In vitro modeling has been used to describe anti-inflammatory properties of perilla. A marked influx of neutrophils and formation of leukotriene B4, along with changes in thromboxane B2 levels, was demonstrated in 1 experiment. In another, large increases in prostaglandin levels were seen. In a contact dermatitis model, perilla induced hypersensitivity mediated by leukotrienes, prostaglandins, histamine, inflammatory cytokines, and immunoglobulin E (IgE).  Extracts of perilla have also been shown to suppress the overproduction of tumor necrosis factor-alpha, a cytokine important in immunologic and inflammatory reactions. Several anti-inflammatory components of perilla leaf have been identified, including luteolin and tormentic acid. In vitro and in vivo immunoenhancing effects have been described for a crude polysaccharide extract isolated from the leaves of perilla. 

Animal data

Topically applied triterpene acids isolated from dried perilla leaves produced a marked reduction in induced ear inflammation in mice.  Greatest improvement was observed with the  of tormentic acid, an ursane triterpene. Inhibition of inflammation with this agent was similar to that produced by hydrocortisone and indomethacin. In another study, orally administered perilla leaf extract inhibited acute inflammation in 3 different models, including one for contact dermatitis. 

Clinical data

Improvement in the symptoms of seasonal allergic rhinoconjuctivitis was reported in a small study (N = 30) of perilla extract enriched with rosmarinic acid. Although objective symptom scores were not affected, patient evaluation of symptoms showed improvement scores of 30%, 55.6%, and 70% for patients receiving placebo, rosmarinic acid 50 mg, and rosmarinic acid 200 mg, respectively ( P = 0.05; placebo vs rosmarinic acid 200 mg). Numbers of inflammatory cells in nasal lavage fluid were significantly lower at 3 days in patients receiving rosmarinic acid. However, this effect was no longer apparent at 21 days.

Animal data

The inhibitory effects of topically applied tormentic acid on carcinogenesis have been investigated in mice. Similar results have been observed with topical application of a perilla leaf extract; the active principle in this study was thought to be luteolin. The effects of orally administered perilla leaf extract were less marked, and no difference in numbers of tumors was observed between controls and perilla-treated groups at 20 weeks. Reduction in the incidence of mammary and colonic tumors has been associated with perilla oil dietary supplementation in laboratory animals.  In vitro experiments with human leukemia and hematoma cell lines have demonstrated apoptotic and cell cycle-arresting properties for perilla leaf extract of greater effect than with rosmarinic acid alone. 

Clinical data

The constituent perilla alcohol has been studied in skin, prostate, and breast cancers, as well as for glioblastoma.

CNS effects
Animal data

In a model of age-related deficits in learning and memory, mice fed a diet enriched with perilla oil exhibited better learning performance and less hyperactive behavior than those fed an alpha-linolenate–deficient diet. Apigenin extracted from perilla was found to have limited antidepressant-like effects in mice.  In mice with stress-induced depression, perillaldehyde reduced the duration of immobility in the forced swimming test.  An anorexigenic effect has been demonstrated in mice fed apigenin both acutely and after 30 days, with no effect on blood glucose or total cholesterol but with decreased triglycerides.  In vitro studies suggest chemical constituents of perilla may act via the monoamine transport system to increase monoamine levels and via inhibition of beta-sectretase enzymes to reduce the production of amyloid protein. 

Clinical data

Research reveals no clinical data regarding the use of perilla in diseases of the central nervous system.


Other uses

Luteolin, extracted from perilla seed oil, showed marked antimicrobial activity against bacteria commonly associated with dental caries.  Activity of perilla oil against toxins produced by Staphylococcus aureus has been demonstrated. 


Perilla leaf extract has been shown to inhibit tyrosinase and melatonin synthesis in mice melanoma cells, suggesting potential applications for skin lightening. 


Perilla oil is rich in alpha-linolenate; health benefits have been theorized with its use. Serum cholesterol and triglyceride levels decreased in rats fed perilla oil. Beneficial changes in the levels of eicosapentaenoic acid and arachidonic acid were also observed in these animals. A trend toward decreased lipid peroxidation was observed in a small study among healthy volunteers who consumed 5 g of powdered perilla leaves for 10 days. 


An orally administered perilla leaf decoction resulted in reductions in proteinuria and in the numbers of glomerular and proliferative cell nuclear antigen-positive cells in animals with mesangioproliferative glomerulonephritis. 



Clinical trials are lacking to provide dosage recommendations. An extract of perilla enriched to contain 200 mg of rosmarinic acid has been used to treat the symptoms of seasonal allergy.  Healthy volunteers consumed 5 g of powdered perilla leaves for 10 days in another study. 


Information regarding safety and efficacy in pregnancy and lactation is lacking.


None well documented.

Adverse Reactions

Dermatitis has been reported in perilla oil workers. Patch testing suggests that 1-perillaldehyde and perilla alcohol contained in the oil are responsible for the effect.  Two cases of anaphylaxis resulting from oral consumption of 500 mg of perilla seeds have been reported. An IgE-mediated response was documented. 


Animals grazing on perilla have developed fatal pulmonary edema and respiratory distress.  Perilla ketone, chemically related to the toxic ipomeanols derived from moldy sweet potatoes, is a potent agent for the induction of pulmonary edema in laboratory animals.  Highest levels of perilla ketone occur in the plant during the flowering and seed stages.  It acts by increasing the permeability of endothelial cells and may not require the presence of cytochrome P450 to increase vascular permeability. 

The toxicity of perilla ketone has been examined in several animal species.  Low intraperitoneal median lethal dose values were observed for mice and hamsters (5 and 13.7 mg/kg, respectively), with far higher lethal doses being required for dogs and pigs (106 and 158 mg/kg, respectively). Perilla ketone-related pathology in dogs and pigs was primarily hepatic, with only minor pulmonary effects, while mice and hamsters displayed only pulmonary lesions. Enzyme bioactivation of perilla ketone may be required for toxicosis, with species unable to produce the perilla metabolite having reduced susceptibility to its poisoning. The volatile perilla oil contains the aldehyde antioxide that has been used in the tobacco industry as a sweetener; however, this compound may be toxic.
