What is the Formal Name of the Butterfly Pea Flower?
The Butterfly Pea plant comes under many names. The formal name of the plant is Clitoria Ternatea. It is also commonly known as Blue Pea and Asian Pigeonwings and is a very common health drink in South East Asia.
It is a climbing plant that grows readily in South East Asia and particularly Thailand and Vietnam where it is used for drinks and as a food coloring. It is from the blue pea flowers that blue flower tea is made.
The flowers are also dried and readily available in most countries. You can use either dried Butterfly Pea Flowers (available here) or fresh flowers to make the tea.
If you look at the individual flowers, which are beautiful, you will understand the feminity of the first part of its formal name – but let’s not go into that.
What is Butterfly Pea Tea?
Butterfly Pea Tea is a drink made by infusing the flowers of the Butterfly Pea plant in hot water, much as regular tea is infused to make tea. It can be drunk either hot or cold and is regularly served in Thai hotels and upmarket massage outlets.
If using fresh flowers you should remove the green stem and leaves since if left on they will turn the tea a little bitter in taste.
If using dried flowers then you can omit this step.
How to Make Butterfly Pea Flower Tea Step by Step
This blue tea is easy to make as you can see from the recipe below or follow along with our video in the recipe.
Just follow along and be amazed but be sure not to steep the flowers too long otherwise the taste will become strong and less pleasant – just as regular tea gets strong if left in the pot too long!
How Does Butterfly Pea Flower Tea Change Color?
You will find children and adults alike amazed at the way the tea changes color when you add lime juice or some other ingredients.
When you make the tea you essentially have a concentrate to dilute which produces a deep blue color that is really quite beautiful and mesmerizing where the ice cubes float.
Adding lime juice or roselle changes the PH of the drink which causes the color to change from deep blue to purple or even red.
If you are into making cocktails it is an easy thing to make some ice with diluted lime juice and the drink will gradually change color as you drink it and making a ring of color that cocktail makers call a mood ring.
It’s a bit of fun for the kids and quite unusual for a drink. Try it!
What are the benefits of Butterfly Pea Tea?
Blue Tea has many health benefits the most well known of which are the anti-oxidants as well as balance to calm the digestive system.
Many people find blue tea increases your energy levels a little and add to alertness and for me, I find it best drunk cold with ice but perhaps that is because Thailand, at least where I live in Central Thailand, is very hot!
The flowers contain catechins which are believed to speed up the metabolism and help burn fat because of the increased calorie burn rate.
Apart from the beautifully exciting blue color of the drink, many people find it helps improve your mood too.
Like green and regular tea, the drink is a mild diuretic which helps your urinary system get rid of excess water and may help reduce anxiety and regulate blood sugar levels but there is not much scientific evidence to back it up yet.
How Many Cups of Butterfly Pea Flower Tea Can You Drink A Day?
Butterfly Pea Flower Tea does not contain caffeine and so avoids the issue that regular tea and, even worse, coffee have and so is a better alternative.
However, like anything, it should be drunk in moderation. I drink 3-5 glasses a day as part of my water intake because drinking plain water all day is quite boring.
In Thailand, you will find the drink served in receptions at hotels, in spas and massage rooms, served after meals and added to various dishes. So you will see it is commonly used.
I stress that I am neither a doctor nor have any medical background but can tell you that the general consensus is that 3-5 glasses a day or less is fine.
Anyway, variety is the spice of life right?
