My coworkers all come to me to get these when they are sick.  I've given them to plant visitors suffering from airline stuffiness/drainage, and they've called me months later to ask the name of the tea again so they can buy some.  Many of them are not tea drinkers, but this is a very soothing beverage that tastes nothing like a classic tea.  It is mildly sweet and they are able to drink it comfortably.  Some add a bit of honey to sweeten it further and increase the soothing quality.  It is usually tolerated by those suffering from drainage tummy upset.
