Commonly found in Thailand. 20 tea bags. Mild flavor. The ONLY REAL BLUE FOOD found in Nature. Brew this tea and cook down to make drink syrups and desserts. Add acid (lemon juice or vinegar) to magically change the blue to violet/Hot Pink! The color change is from the powerful anthocyanin antioxidants which change color depending on acidity. In herbal medicine, this tea is used for improving memory, circulation and eyesight. It can also be used to color desserts and rice. Sourced from a family farm and grown without pesticides or chemicals. Individually wrapped bags.
