What exactly is butterfly pea flower tea?
Butterfly pea flower tea comes from the vivid blue petals of the Clitoria ternatea plant, native to Southeast Asia. This striking blue drink has been used for centuries in traditional medicine and cooking across Thailand, Malaysia, and other parts of Southeast Asia.
The tea is made by steeping dried butterfly pea flowers in hot water, creating a caffeine-free beverage that’s gaining fans worldwide. Unlike many herbal teas, butterfly pea flower tea offers more than just flavor – it provides a visual experience that changes with simple kitchen ingredients.
In its native regions, the plant has deep cultural roots. Traditional healers have used it in Ayurvedic medicine for memory enhancement, stress relief, and hair health. The flowers have also colored foods naturally for generations, adding vibrant blues to rice dishes and desserts.

- India: Aparajita or Shankhpushpi
The science behind the magic: why does it change color?
The color-changing property of butterfly pea flower tea isn’t magic – it’s chemistry at work! The secret lies in compounds called anthocyanins, which are natural pigments in the flowers.
These anthocyanins act as pH indicators, changing their molecular structure when they contact acids or bases. When you brew the tea, it appears blue. Add something acidic like lemon juice, and the anthocyanins shift their structure, turning the liquid from blue to purple and even pink!
The science is simple:
- In neutral or slightly basic environments: The tea remains blue
- In acidic environments: The tea shifts to purple or pink
- The more acidic the addition: The more dramatic the color change
This reaction happens instantly, making it both fun to watch and a perfect natural pH indicator for science experiments.
Specific anthocyanins in butterfly pea flowers
Butterfly pea flowers contain unique anthocyanins called ternatins (specifically ternatin A1-A3 and B1-B4), which differ from those found in blueberries (primarily malvidin) or purple cabbage (primarily cyanidin). These specific compounds:
- Create a more stable blue color than most other plant sources
- Provide potentially higher antioxidant activity
- Demonstrate exceptional pH sensitivity for dramatic color changes
- Show better stability in various food applications
Research from Thailand’s Chulalongkorn University (2018) found that butterfly pea anthocyanins maintain their color better in neutral foods compared to other blue plant sources.
What does butterfly pea flower tea taste like?
The flavor of butterfly pea flower tea often surprises first-time drinkers. Despite its striking color, the taste is subtle and earthy with mild floral notes. Many compare it to a light green tea but without the grassy undertones.
On its own, the tea has:
- A woody base note
- Subtle floral hints
- A clean, smooth finish
- A gentle sweetness (mild, not strong)
The mild flavor makes butterfly pea flower tea an excellent canvas for other ingredients. Adding honey brings out its natural sweetness, while lemon not only changes the color but adds brightness to the taste profile.
Unlike some herbal teas that have strong medicinal flavors, butterfly pea tea remains pleasant and approachable. Its taste doesn’t change when the color transforms – only the added ingredients alter the flavor.

Potential health benefits of butterfly pea flower tea
Rich in antioxidants
Butterfly pea flowers contain powerful antioxidants, particularly anthocyanins – the same compounds responsible for the vivid blue color. These antioxidants help fight free radicals in the body, which can damage cells and contribute to aging and disease.
Research suggests the antioxidant activity in butterfly pea extract is comparable to vitamin E in some studies. Regular consumption might help reduce oxidative stress, though more human studies are needed to confirm these effects.
Potential nootropic effects
Traditional medicine systems have long used butterfly pea tea to boost memory and cognitive function. Modern research has begun to examine these claims.
Some studies suggest compounds in the tea may affect acetylcholine levels in the brain – a neurotransmitter linked to memory and learning. Animal studies have shown promise for memory enhancement and neuroprotective effects, though human research remains limited.
Researchers at Khon Kaen University (Thailand, 2019) found that butterfly pea extract improved memory scores in animal models, potentially through its effects on the cholinergic system.
May support skin & hair health
The antioxidants in butterfly pea tea may benefit skin health when consumed regularly. Traditional uses include applying the tea directly to hair to enhance growth and reduce graying.
These traditional uses have some scientific backing – the antioxidants can help protect against environmental damage, and some compounds may support collagen production.
Potential anti-inflammatory properties
Test tube and animal studies suggest butterfly pea flower extract has anti-inflammatory properties. The flowers contain cyclotides and flavonoids that may help reduce inflammation markers.
These properties could explain its traditional use for treating inflammatory conditions, though clinical evidence in humans remains preliminary.
A 2020 study published in the Journal of Ethnopharmacology confirmed moderate anti-inflammatory effects of butterfly pea extract on cellular inflammation markers.
May help regulate blood sugar levels
Early research indicates butterfly pea flower extract might help maintain healthy blood sugar levels. Animal studies have shown promising results for improving insulin sensitivity.
The tea contains compounds that may slow carbohydrate absorption and improve glucose uptake in cells. However, people with diabetes should consult their doctor before using it as a supplement.
Other potential benefits
Additional reported benefits that have some research support include:
- Mild stress reduction properties
- Support for eye health through proanthocyanidins
- Possible antimicrobial effects
- Gentle detoxification support
While these benefits have traditional use and some research backing, remember that most studies are preliminary. The tea works best as part of a healthy lifestyle, not as a medical treatment.
