The most notable feature of Blue Butterfly Pea is its striking deep blue color. The petals of the flower contain natural pigments called anthocyanins, which are responsible for the intense blue hue. When the flowers are steeped in hot water or any acidic liquid, they release the color, transforming the liquid into a rich blue infusion.

Blue Butterfly Pea flowers are often used as a natural food coloring agent due to their vibrant blue color. The infusion obtained from steeping the flowers can be used to naturally dye foods and beverages, giving them a blue or purple tint. It is commonly used in traditional desserts, drinks, rice dishes, and herbal teas.

The blue color of Blue Butterfly Pea infusion can change when it comes into contact with acidic ingredients such as lemon or lime juice. It transforms from blue to purple, creating a visually appealing effect in cocktails, mocktails, and other beverages.

Blue Butterfly Pea is also recognized for its potential health benefits. The flowers contain various bioactive compounds, including antioxidants, flavonoids, and alkaloids, which contribute to their medicinal properties. The plant has been traditionally used in Ayurvedic and traditional medicine for its reputed effects on cognitive function, stress reduction, and overall wellness.
