I added Key Lime and Tangerine to my product lineup about a year ago, and both of them are so invigorating. Having a bad day? Take the lid off, take a whiff and feel better fast. As said before, citrus (of any kind) = energy! Tangerine is a relaxant, sedative, even hypnotic, and indicated for overexcited children. A drop of either tangerine or mandarin in a half glass of hot water with a bit of honey makes a wonderful bedtime drink for children.
