Butterfly Pea
FabaceaeClitoria ternatea
Also known as: Aparajita, Shankpushpi (in some traditions), Blue Pea
clinical_notes Clinical Summary
Butterfly Pea (Clitoria ternatea), known as Aparajita in Ayurveda, is a traditional Southeast Asian/Indian medhya (brain-tonic) herb whose striking blue flowers are rich in anthocyanins (ternatins), flavonoids, and cyclotides.
Preclinical evidence supports memory-enhancing, anxiolytic, anticonvulsant, antioxidant, and anticholinesterase activities — mechanisms include AChE inhibition and neuroprotection in chronic cerebral hypoperfusion models.
Large-scale human RCTs are lacking but traditional use is extensive and flowers are widely consumed as food coloring.
Pregnancy Safety
Food amounts (tea from flowers) likely safe; medicinal doses of root/seed extract avoid due to insufficient data. Root traditionally considered emmenagogue in some sources.
Lactation Safety
Limited safety data; food amounts likely safe, avoid concentrated extracts.

Traditional Chinese Medicine (TCM)
蝶豆 (Dié Dòu (or Lán Hú Dié))
Nature: cool
- Heat toxin
- mild anxiety
- inflammation
- cooling tonic
Not a classical TCM herb but has been adopted in some Southeast Asian and modern TCM practices for its cooling, detoxifying properties. Not featured in canonical materia medica.
Traditional Uses Across Healing Systems
While many herbs lack controlled clinical trials, centuries of traditional practice across cultures provide valuable insight into their therapeutic applications.
Known as Aparajita (and sometimes confused with Shankhpushpi); used as Medhya Rasayana (brain tonic) for memory enhancement, anxiety, depression, insomnia, and neurological disorders. Roots for depression, seeds as laxative, flowers for eye health.
Categorized as a medhya (intellect-promoting) herb. Note: 'Shankhpushpi' is an Ayurvedic classification that may refer to this herb or to Convolvulus pluricaulis or Evolvulus alsinoides.
Used as memory tonic and anxiolytic; for hair care and as hair dye.
Mukherjee notes extensive Unani use for neurological health.
In Southeast Asia (Thailand, Malaysia, Indonesia), flowers used as natural food coloring for rice dishes, desserts, and beverages (butterfly pea tea); also for skin and hair care.
Pleasant-tasting blue tea turns purple with lemon (pH change).
Recently popularized globally as a nootropic and anti-aging ingredient in teas, cosmetics, and supplements; modern herbalists use for anxiety and cognitive support.
Featured in functional beverages and nootropic blends.
spa Parts Used
flower
- anxiety
- cognitive support
- skin inflammation
- eye health
Dried blue flowers used as tea or food coloring; best brewed in cool-warm water to preserve anthocyanins.
root
- memory enhancement
- depression
- insomnia
- neurological disorders
Main medhya part in Ayurveda; decocted or tinctured. Traditionally considered stronger for CNS effects than flowers.
seed
- constipation
- skin conditions
Seeds traditionally used as mild laxative; pulverized.
shield Safety
Contraindications — Evidence Basis
Pregnancy
Limited safety data; traditional use of root extracts as an abortifacient/emmenagogue in some sources warrants caution. Flowers used as food coloring are likely safe in food amounts.
Anticoagulant or antiplatelet therapy
Flavonoid and anthocyanin content may inhibit platelet aggregation; theoretical risk of increased bleeding.
Concurrent sedative medication
Has demonstrated sedative and anxiolytic effects; may potentiate CNS depressants.
Toxicity
Safety studies show up to 200 mg/kg root extract is safe in rats with no observed adverse effects; whole flower as food/tea is GRAS.
Nausea, diarrhea (at very high doses of root extract).
Discontinue; symptomatic care.
Adverse Effects
CYP Metabolism
Limited clinical data; flavonoids may mildly modulate CYP1A2 and CYP3A4 in vitro.
swap_horiz Interactions
Glibenclamide (Glyburide)
Class: Sulfonylurea antidiabetic
Clitoria ternatea flower extract exerted antidiabetic effects in streptozotocin-induced diabetic rats via antioxidant, anti-inflammatory, and GSK-3β-modulating actions, enhancing the hypoglycemic effect of glibenclamide.
Monitor blood glucose regularly, especially when starting or discontinuing butterfly pea. Dose reduction of sulfonylurea may be required.
Aspirin
Class: NSAID / antiplatelet
Butterfly pea flavonoids (kaempferol, quercetin) have demonstrated anti-inflammatory activity with reported 65-82% inhibition of carrageenan-induced paw edema and 75-76% writhing inhibition in mice, suggesting additive anti-inflammatory effect with NSAIDs.
Effect is generally additive and mild. Monitor for GI upset with long-term concurrent use.
Isoniazid
Class: Antitubercular agent
In a clinical trial, adjuvant butterfly pea flower therapy with anti-TB treatment increased pro-inflammatory IFN-γ expression compared to anti-TB therapy alone, and improved leukocyte and platelet parameters as well as clinical symptoms.
Appears safe and complementary in tuberculosis treatment; monitor for normal TB treatment response and liver enzymes (both agents can affect hepatic function).
Warfarin
Class: Vitamin K antagonist anticoagulant
Butterfly pea anthocyanins and flavonoids have mild antiplatelet activity in vitro. Additive bleeding risk is theoretical but possible at high supplemental doses.
Monitor INR if consuming large quantities (e.g., concentrated extract). Typical food/tea use is unlikely to cause clinically relevant changes.
Fluoxetine
Class: Selective serotonin reuptake inhibitor (SSRI)
Traditional Ayurvedic use of Clitoria ternatea for cognitive enhancement and mood support is paralleled by flavonoid activity on SRC/ESR1/PI3K pathways; potential for mild additive serotonergic/antidepressant-type effects.
Effect is mild and unlikely to cause serotonin syndrome. Routine monitoring of mood and efficacy of SSRI is sufficient.
Atorvastatin
Class: HMG-CoA reductase inhibitor (statin)
Butterfly pea flower extract reduced lipid profile and improved atherosclerosis biomarker profiles in obese rats, offering additive lipid-lowering to statin therapy.
Generally beneficial combination. Monitor lipid panel as clinically appropriate.
hub Combinations
Synergistic pairings can enhance therapeutic outcomes, while knowing suitable substitutes helps when specific herbs are unavailable or contraindicated.

science Studies
Clitoria ternatea Flower Extract Attenuates Postprandial Lipemia and Increases Plasma Antioxidant Status Responses to a High-Fat Meal Challenge in Overweight and Obese Participants
RCTThis randomized trial enrolled 16 overweight or obese men (mean age 23.5, BMI 25.7) who consumed a high-fat meal alone or with 1 g or 2 g of Clitoria ternatea flower extract (CTE). Postprandial plasma glucose, triglycerides, free fatty acids, and pro-inflammatory markers were measured alongside antioxidant status (FRAP). CTE at 2 g significantly reduced postprandial serum triglycerides and free fatty acids compared to the high-fat meal alone, and both doses improved plasma antioxidant capacity (FRAP and thiol levels). CTE also attenuated high-fat meal-induced increases in MDA (lipid peroxidation marker). These findings suggest CTE has beneficial effects on postprandial lipid metabolism and oxidative stress in overweight individuals, relevant to cardiovascular risk reduction.
The nootropic and anticholinesterase activities of Clitoria ternatea Linn. root extract: Potential treatment for cognitive decline
In VivoThis in vivo study in a chronic cerebral hypoperfusion (CCH) rat model investigated the effects of Clitoria ternatea root extract (CT) on memory deficits and cholinergic function, with chronic oral administration of 100, 200, and 300 mg/kg for 28 days alongside a 28-day toxicity assessment. CT root extract at 200 and 300 mg/kg significantly restored CCH-induced memory impairments and reduced neuronal damage in the CA1 hippocampal region. The high dose (300 mg/kg) significantly inhibited elevated acetylcholinesterase (AChE) activity in the frontal cortex and hippocampus. Repeated doses were found safe in this 28-day protocol. These results provide scientific evidence supporting CT root extract as a potential therapeutic strategy for vascular dementia-related cholinergic abnormalities and cognitive decline.
