This tea does exactly what it is supposed to do. Open up the nasal passages and help a person breath. I also will recommend the David’s Tea Cold Survival Kit. It is eveything you need to beat a cold or at least feel cozy while suffering. Each tea packet in the kit explains what it dowes and what it is for. I even buy refills to keep my kit well stocked. The perfect Go-to-Box of wellness teas for sickies!
