A beautiful herbal tea with a bright blue light blue! Sea creatures live leisurely in the vast ocean. Relaxing tea time with "Aqua Terrier". A mysterious herbal tea that changes color! Aqua Terrier is a blend of lemongrass with the legume herb "butterfly pea" native to Thailand. Because the shape of the flower resembles a butterfly, it is named butterfly pea and has been loved by women for a long time in Thailand, a beauty powerhouse. Pour hot water into a tea bag and the blue herbal tea is ready! You can enjoy the refreshing aroma and taste of lemongrass. If you add acid (lemon juice, sparkling water, white wine, etc.) to the finished herbal tea, it will change from blue to purple. Butterfly peas and lemongrass have zero caffeine. Recommended for those who are concerned about caffeine.
