This smoothie from Tess Masters, aka The Blender Girl, is packed with cold and flu fighting ingredients - and is a perfect summer refreshment! This smoothie comes from her latest book, The Blender Girl Smoothies. Here's what Tess says about this smoothie: "This is a cold-and-flu buster and potent detoxifier, all in one zesty cocktail! The bromelain in pineapple suppresses coughs and loosens mucus, while mint clears respiratory congestion, soothes sore throats, and alleviates nausea. The vitamin C in limes has antibiotic power, anti-inflammatories in kale and pineapple combat arthritis, and ginger boosts immunity, aids digestion, and adds a powerful zing."
