Palo azul means "blue wood", and it gets its name because the plant's wood produces this extraordinary blue fluorescent tea. Palo azul's fluorescence is caused by nutrients (polyphenols) which also make it antioxidant, anti-inflammatory, kidney-protective, and liver-protective. That’s why it’s also known as “kidneywood”, because it's been used as a kidney remedy for over 500 years! Studies show that palo azul has around 8x more antioxidants than green tea, and it has 0 caffeine, 0 oxalates, and 0 sugar, so you can enjoy Mother Nature's most magical tea at any time of the day. Ingredients: 100% Organic palo azul Tasting Notes: Earthy, smooth, slightly sweet, refreshing and not bitter. Although palo azul has 0 sugar, it has a subtle natural sweetness and that's why it's also known as palo dulce (sweet wood).
