This tea is a life savior for me. Anytime I start to feel like I am coming down with a cold or start to feel a sore throat coming on, I grab my 21st Century tea by Mountain Rose Herbs and I’ll be fine by the next day. This tea works better for me than the Echinacea and Roots tea by the same vendor. 21st Century tea is a lot of nettle leaf, red clover blossoms and elderberries. I love this tea!
