What kind of tea are you are drinking is important to know.
I had some influenza last week and I drank a lot of chamomile tea and it has many positive properties.
For what I know, is that chamomile tea has two primary
agents: alfa-bisabolol and chamazulen and they have anti-inflammatory effect just like Garlic and ginger.
demonstrated that chamomile is anti-inflammatory, antihyperglycemic, and anticancer properties:
