Butterfly pea flower might just be one of nature’s most beautiful surprises. With its striking blue petals and subtle earthy taste, this plant has been used for centuries in traditional medicine and is now finding its way into modern wellness routines, teas, and even smoothies.

Known for its vibrant colour and potential health benefits, butterfly pea flower has long held a place in Ayurvedic and Southeast Asian traditions. What was once brewed as a calming herbal remedy is now being rediscovered by those looking for natural ways to support the body and mind.

In this article, we’ll explore what butterfly pea flower is, where it comes from, how it was traditionally used, and why it’s gaining popularity today. You’ll also find an easy tea and smoothie recipe, learn what it tastes like, and discover whether it really turns your tongue blue.

Let’s dive into the world of this fascinating blue bloom.

What Is Butterfly Pea Flower?

Butterfly pea flower comes from the plant Clitoria ternatea, a climbing vine native to Southeast Asia. It’s best known for its vibrant, electric blue petals, which have been used for centuries in herbal teas, traditional medicines, and natural dyes.

The flower grows easily in warm climates and is often found in gardens, growing along fences or trellises. Its distinctive appearance, bright blue with a delicate shape, makes it both eye-catching and unique. While the plant also produces small green pods, it’s the flowers that have gained the most attention for their natural pigment and potential health benefits.

Butterfly pea belongs to the legume family, which includes peas and beans, but it’s not used in the same way as typical food crops. Instead, the dried petals are steeped in hot water to create a blue herbal tea, or ground into a fine powder for use in smoothies, baking, and skincare.

Though relatively new to the Western wellness world, this flower has a long-standing reputation in traditional healing practices and it’s quickly earning a place in kitchens and apothecaries around the globe.

Origins in Traditional Medicine

Long before butterfly pea flower made its way into lattes and Instagram reels, it held a respected place in ancient healing systems, particularly in Ayurvedic medicine and traditional practices across Southeast Asia.

In Ayurveda, Clitoria ternatea is known as Shankhpushpi and is traditionally used to support brain health, memory, and clarity of thought. It’s believed to help calm the nervous system, reduce stress, and improve mental focus. These calming and mind-boosting properties made it a go-to remedy for those seeking balance and mental clarity.

In Thai and other Southeast Asian traditions, the flower was often used as a natural dye, a herbal tonic, and even a symbol of beauty and spirituality. It was commonly steeped into blue tea for its cooling and anti-inflammatory effects or added to rice and desserts to create rich blue or purple hues, especially in ceremonial and festive meals.

The use of butterfly pea wasn’t just for its colour, it was also valued for its soothing properties, particularly for the eyes, skin, and mind. Many cultures also used it to support hair growth, reduce oxidative stress, and promote a sense of calm.

What’s remarkable is how these traditional uses are now being explored and supported by modern science, confirming what ancient practitioners seemed to know all along: this little blue flower holds more than just visual charm.

How Was It Discovered or First Used?

While there isn’t a single story that marks the “discovery” of butterfly pea flower, its use can be traced back thousands of years through the oral traditions and texts of Ayurvedic medicine and Southeast Asian culture.

In India, the plant was often grown in temple gardens and used in offerings to deities, thanks to its vibrant colour and symbolic purity. Ayurvedic texts mention Shankhpushpi as a brain tonic and stress reliever, and Clitoria ternatea became one of the key herbs used for calming the mind and supporting cognitive function.

In Southeast Asia, particularly Thailand, Malaysia, and Vietnam, the flower was used in herbal medicine and as a natural dye for food and fabric. Villagers would often steep the flowers in water to create a blue tea, or squeeze a few drops of lemon juice into the infusion to watch it turn purple, both for its refreshing taste and its cooling effect on the body.

Its first uses were practical, spiritual, and medicinal all at once: a plant that coloured meals, calmed the mind, and was rooted in cultural rituals and everyday wellness. Over time, as trade and travel spread traditional herbs beyond their native regions, butterfly pea flower started gaining attention from herbalists, chefs, and researchers across the world.

Now, it’s found its way into modern teas, supplements, skincare, and recipes but its story begins with those who trusted the wisdom of the earth long before science caught up.

Why Is It Called “Butterfly Pea Flower”?

The name “butterfly pea flower” might sound whimsical, but it’s rooted in both the plant’s appearance and its botanical classification.

The word “butterfly” comes from the shape of the flower itself. Its delicate, fan-like petals resemble the wings of a butterfly in flight, especially when the flowers are in full bloom. In some cultures, people even believed that butterflies were drawn to the plant, adding a layer of symbolism around transformation, beauty, and nature.

The word “pea” refers to the plant’s place in the legume family, which includes familiar crops like green peas, chickpeas, and lentils. Like many legumes, the butterfly pea plant produces seed pods after flowering, although the flowers are its most used and celebrated part.

Its scientific name, Clitoria ternatea, was given by the 17th-century botanist Carl Linnaeus. He chose the name because the flower’s shape reminded him of female anatomy, a naming choice that has since sparked both curiosity and controversy.

Despite the unusual name, “butterfly pea flower” has a poetic quality to it and perfectly captures the plant’s gentle, graceful presence in the natural world.

What Does Butterfly Pea Flower Taste Like?

Butterfly pea flower has a mild, earthy flavour that’s often described as subtle and soothing. On its own, it tastes somewhat similar to green tea or chamomile, with a delicate, slightly woody or floral undertone.

It isn’t sweet or overpowering, which makes it a versatile ingredient in both food and drink. When steeped in hot water to make tea, the flavour remains gentle and calming, ideal for sipping slowly, especially in the evening or during moments of relaxation.

Because the taste is so neutral, it pairs well with other ingredients. You’ll often see it blended with herbs like lemongrass, mint, or ginger, or combined with citrus to add a bright twist. When used in smoothies or baked goods, it contributes more to colour than flavour, which means you can enjoy its visual appeal without it affecting the overall taste of the recipe.

Its mildness is part of its charm. It allows the flower to fit easily into many recipes, bringing a natural pop of colour without overwhelming the senses.

Does It Give You a Blue Tongue?

It’s a fair question, especially if you’ve seen just how vibrant butterfly pea flower can be in teas and smoothies. The deep blue pigment might look intense, but in most cases, drinking butterfly pea tea or eating something made with the powder won’t leave your tongue blue.

That said, it depends on how concentrated the drink is and how much you consume. If you’re sipping a strong tea or eating a dessert made with a generous amount of butterfly pea powder, you might notice a temporary tint on your tongue or lips but it’s usually subtle and fades quickly.

The bright colour comes from natural antioxidants called anthocyanins, which are the same pigments found in blueberries and red cabbage. These are water-soluble and safe to consume, and they don’t typically stain like artificial dyes.

So, while it might give you a slight blue tinge for a moment, especially if you’re enjoying a highly pigmented smoothie, it’s nothing to worry about, and many people find it part of the fun.

Health Benefits of Butterfly Pea Flower

Butterfly pea flower has been used in traditional medicine for centuries, and today, modern research is starting to uncover the science behind its health-supporting properties.

1. Rich in Antioxidants

Butterfly pea flower contains powerful antioxidants, especially anthocyanins, which help neutralize free radicals and reduce oxidative stress. This can support overall cellular health and may play a role in slowing signs of aging.

2. Supports Brain Function

Traditionally used in Ayurvedic medicine to enhance memory and concentration, the flower is thought to have neuroprotective effects. Early research suggests it may help support mental clarity and cognitive function.

3. Natural Stress Relief

Thanks to its calming properties, butterfly pea flower tea is often used to relax the mind and body. It’s caffeine-free, making it a soothing choice for winding down in the evening.

4. Anti-Inflammatory Properties

Some studies suggest butterfly pea flower may help reduce inflammation in the body, which is linked to a wide range of chronic conditions, from joint pain to cardiovascular issues.

5. May Support Skin and Hair Health

The antioxidants and flavonoids in butterfly pea flower are believed to support collagen production, protect against premature skin aging, and promote stronger, healthier hair.

6. Supports Eye Health

Traditional use also includes supporting vision. The anthocyanins in the flower may help increase blood flow to the eyes and reduce strain, though more research is needed to fully support this benefit.

7. Potential Blood Sugar and Blood Pressure Support

Early animal studies have shown that extracts from the plant may help regulate blood sugar levels and support healthy blood pressure, though human studies are still limited.

While more research is needed in many areas, butterfly pea flower remains a gentle, natural option for those seeking to support their wellbeing in a holistic way.

Butterfly Pea Flower Tea Recipe

One of the simplest and most popular ways to enjoy butterfly pea flower is as a herbal tea. It’s calming, naturally caffeine-free, and absolutely beautiful to look at, especially when you add a splash of lemon and watch the colour shift from blue to purple.

Precautions and Considerations

While butterfly pea flower is generally considered safe for most people when used in moderation, there are a few things to keep in mind before adding it regularly to your routine.

1. Pregnancy and Breastfeeding

There isn’t enough research to confirm whether butterfly pea flower is completely safe during pregnancy or breastfeeding. If you’re pregnant, trying to conceive, or nursing, it’s best to consult a healthcare professional before using it.

2. Allergic Reactions

Although rare, some people may experience mild allergic reactions. If you’re trying it for the first time, start with a small amount and monitor how your body responds.

3. Medication Interactions

If you’re taking medications for blood pressure, blood sugar, or are on anticoagulants, it’s worth checking with a healthcare provider, as butterfly pea flower may have mild effects on these systems.

4. Quality Matters

Choose organic, lab-tested butterfly pea products whenever possible to avoid pesticide residues and contaminants. Look for brands that provide transparent sourcing and testing information. If lab results aren’t shared publicly, it’s worth emailing the company directly to request proof of testing.

As with any natural remedy or superfood, listening to your body and choosing quality sources is key to getting the best results.
