How To Make Blue Tea At Home

South Asian-born blue tea, also referred to as butterfly pea tea, is an herbal brew. It is created by brewing the dried petals of the Clitoria Ternatea L. plant, which is distinguished by its distinctive bright blue hue.

Blue tea is popularly drunk for its health properties in addition to serving as a natural food coloring. For example, it purportedly has positive benefits on the heart and brain as well as anti-diabetic and anti-cancer properties.

You can drink blue tea hot or cold, and making a cup is simple. If you are tired of traditional green tea and want something new, you will love blue tea. It’s not only amazing to look at but tastes excellent with citrusy flavor and aroma.

You must be wondering how blue tea changes colors to light purple and turquoise. Well, the secret behind that is acidity and PH. When you add lime juice to the tea, it changes color from deep blue to purple because of the change in PH levels.

The entire process is very mesmerizing and quite beautiful. That is why Butterfly Pea Flowers are mostly used to make cocktails and teas. The tea will gradually change color as you drink it.

It is quite fun for kids as well. You can make blue-purple mocktails with butterfly pea flower extract for kids.

Benefits of Blue Tea

Blue tea is rich in antioxidants and helps in digestion. If you have a heavy meal, you can take a cup of warm or cold blue tea to calm your digestive system.
