How to Make Palo Azul Tea So it Always Looks Blue!

Palo Azul Recipe

Is your palo azul not turning blue? This is how we make palo azul tea so that it reveals its extraordinary blue fluorescence everytime!

1. Boil 1 gallon of alkaline water and add 1 oz of palo azul bark (2-3 pieces or a small handful).
2. Brew on low heat for 20 minutes, then let it cool down.
3. Strain and remove the palo azul plant. Store the tea in the fridge.
4. Pour the tea in a glass cup so that it can absorb light and turn blue
5. Take the tea outside so it can absorb sunlight and enjoy the magic!

If you want an even more potent brew, you can simmer it on low heat for a longer period of time and this will extract more goodness out of the bark. Additionally, you can use more palo azul or less water to have a more concentrated brew. 

A 2018 study mentions that "traditionally, one or two small pieces of the bark, or approximately 10 g (0.3 oz) of branches and leaves of E. polystachya (palo azul) are prepared as infusion, decoction, or maceration."

Boiling may increase polyphenol content

In case you were wondering if boiling palo azul would destroy its beneficial nutrients, a 2018 study actually found that boiled leaves "have shown greater levels of polyphenols, flavonoids, and antioxidant capacity compared with fresh leaves." Not only did boiling preserve the nutrients, they found that the "polyphenol and flavonoid contents of boiled leaves were higher than that of their fresh form." 

The authors suggest that the increase in polyphenol content could be attributed to the "breakdown of the complex polyphenolic compounds such as tannins present in the vegetables during heat processing to simple polyphenols" and "the liberation of polyphenols from the intracellular protein complexes, changes in plant cell structure, matrix modifications, or the inactivation of the polyphenol oxidases."

Cold Brew

1. For the best cold brew, add a few pieces to room temperature water and leave it overnight so that it brews effectively.
2. For a quick on-the-go drink, simply add some palo azul to your cup, bottle or thermos. Shake it up a bit, and you will see it start to turn blue in 1-3 minutes.

A cold brewed infusion will not be as potent or concentrated, so it will have a lighter color...but you should still be able to see the blue fluorescence.

Microwave

1. Add 1 piece of palo azul bark to a microwave-able cup
2. Microwave for 2 minutes
3. Let it cool down and transfer it to a glass cup so that your palo azul tea can absorb light and reveal its magic!
