Although the Medicine Ball's official origin story is unknown, it appears to have started catching on around October 2016, and has since generated quite a bit of attention on Instagram as a "miracle cold cure." There are also apparently several ways to make it, but according to the Starbucks spokesperson we reached out to, this is the recommended recipe: "In a hot cup, add a bag of Teavana Jade Citrus Mint Tea and a bag of Teavana Peach Tranquility Tea. Add half hot water and half steamed lemonade. Add a packet of honey and an optional pump of peppermint."
It's unclear how or if the concoction can actually fight off any common cold, but it sure does sound damn delicious.
