Blue Tea: Everything You Need To Know

The colour changing tea you’ve probably never heard of!

Brightly coloured ‘mermaid’ and ‘unicorn’ beverages have been a big Instagram trend lately. But if like us, you’re not a fan of sugar, syrups and sprinkles then we have some good news! Sometimes nature can be far more magical! Blue Voodoo is a brightly coloured ‘blue tea’. It changes from blue, to a brilliant purple colour with just a squeeze of lemon juice. Amazingly, this transformation is 100% natural! How can this be a real thing and why have I never heard of this magical tea, you ask? We’ve got the answers to all your questions!

What is blue tea?

We call our Blue Voodoo blend a ‘blue tea’ because it contains ‘blue pea’ flowers (sometimes called ‘butterfly pea’ flowers). These flowers are native to South East Asia, where they have been brewed to make tea since ancient times.

Blue tea, or ‘blue pea flower tea’ has been enjoyed for centuries in Thailand, Vietnam, Bali and Malaysia, where the flowers are also commonly used in cooking. In Bali, blue tea is a medicinal mainstay called, Bunga telang and used to treat everything from inflammation to eye disease. In traditional Chinese medicine, blue pea flowers are said to improve vitality and even raise libido. In Ayurvedic medicine, blue pea flowers are ascribed with memory enhancing, anti-stress and anti-depressant properties.

Does blue tea have any health benefits?

We did some research on the blue pea flower and here’s what people say:

  • High in antioxidants: Blue pea flowers contain antioxidants called proanthocyanidins, which may help prevent and repair cellular damage from free oxygen radicals (according to a study here).
  • Anti-aging: Blue pea flowers contain anti glycation, which according to this study, may fight the signs of ageing in the skin (we’ll take that!).
  • Anti-inflammatory & analgesic (pain relieving) properties: Blue pea flowers have been used to treat eye disease because they act as a natural anti-inflammatory. You can read more here.
  • Improve memory & brain function: One study found that blue pea flowers might assist with memory and brain function, because the flowers help increase Acetylcholine, a chemical that’s important for communication in the brain. As we age, the brain stops being able to produce as much Acetylcholine.

Blue Voodoo: colour changing properties

Blue Voodoo tea is naturally a vivid, blue colour thanks to the blue pea flowers in the blend. Depending on the strength and how long you brew the tea for, it will start out a turquoise green colour, then change to a deeper blue. Because blue pea flowers are sensitive to changes in pH levels, adding a slice of lemon will cause the tea to turn bright purple almost instantly! This doesn’t affect the properties of the tea but it’s pretty fun to watch!

    Is this caffeine free?

    • chloe@yumchaa.co.uk

      Hi Dorthe, the Blue Voodoo blend contains green tea, so it is not caffeine free. This tea contains much less caffeine than black tea but does contain some caffeine. Hope this helps!
