Butterfly pea flower tea, also known as blue tea, is a type of herbal tea made from the dried flowers of the butterfly pea plant (Clitoria ternatea). This tea is named after the vibrant blue color it imparts when steeped in hot water. Here are some key characteristics and information about butterfly pea flower tea:
- Color: One of the most distinctive features of butterfly pea flower tea is its striking blue or indigo color. When the dried flowers are steeped in hot water, they release natural pigments called anthocyanins, which give the tea its blue hue. The color can vary in intensity depending on the concentration of flowers and the pH level of the liquid used. It can turn purple or pink when lemon juice or acidic substances are added.
- Taste: Butterfly pea flower tea has a mild, earthy, and slightly vegetal flavor. It is generally considered to be a caffeine-free herbal tea and is often enjoyed for its calming and refreshing qualities.
- Health Benefits: Butterfly pea flower tea is believed to have several potential health benefits due to its rich content of antioxidants and anthocyanins. These compounds have been associated with anti-inflammatory and antioxidant properties. Some people consume it for its potential to support skin health, reduce stress, and aid in digestion, but more research is needed to confirm these effects.
- Culinary Uses: Butterfly pea flower tea is not only consumed as a standalone beverage but is also used in various culinary applications. Its vibrant color makes it a popular natural food coloring agent, and it is often used to tint rice, beverages, desserts, and cocktails.
- Traditional Use: The butterfly pea plant is native to Southeast Asia and has a history of traditional use in Thai and Ayurvedic medicine. It has been used for centuries for its potential medicinal properties.
- Variations: Some variations of butterfly pea flower tea include blending it with other ingredients such as lemongrass or ginger to add flavor and depth to the tea.
- Herbal Infusions: In addition to being consumed as a standalone tea, butterfly pea flower tea is sometimes used in herbal infusions or blended with other herbs and botanicals to create unique flavor profiles.
- Natural pH Indicator: Butterfly pea flower tea is known to act as a natural pH indicator. When lemon juice or other acidic substances are added, the tea changes color, making it a fun and interactive element in certain beverages and cocktails.

Keep in mind that the color-changing effect of butterfly pea flower tea is temporary and may fade over time, so it is often used for immediate visual impact in drinks and dishes.
