Throughout the development of the INDIGO Collection, the entire TATCHA team continued to be intrigued by how closely modern medical research on indigo extract mirrored the traditional lore. As we prepared to share it with our friends, we learned that the botanical – also known as indigofera tinctora - was even more incredible than we had thought.
- Although the Indigo flower is red, the entire plant is cultivated and fermented in water to create the famously deep blue dye. The fermenting liquid is actually an earthy green, and the fabric turns blue after it is exposed to the air and oxidizes.
- You can even eat and drink it! There’s Indigo tea made from the plant’s seeds and leaves (hard to come by in the US) that tastes a lot like genmaicha, a green tea made with toasted brown rice. We’ve also seen indigo noodles, sake and even desserts.
- Additionally, Indigo extract has been prescribed as an oral supplement in Traditional Chinese Medicine for thousands of years to treat a variety of internal inflammatory illnesses including inflammatory bowel diease.
- Science has long used blue lights to treat a variety of ills, including addiction and depression. The National Institute of Health reported that exposure to this blue light led to more awake, alert subjects.
- Indigo continues to be an inspiration for artists and dyers. More than 200 strips of Indigo-dyed fabric were hung outside on display as part the “Returning Indigo” installations throughout Japan in 2012. Visitors were invited to select their favorite hue and cut a small piece of fabric from their favorite and make a pin.
