Should reduce fever, ease the stomach, and help loosen congestion.
Unfortunately, I don't HAVE any of the above accept the cinnamon and the Honey.
Another good one for congestion is vinegar and honey. Hot. You KNOW you need relief badly when you don't even taste the vinegar.
Us Heathen/Pagan types are pretty good with the herb stuff...
Some of us medievally inclined Catholics are pretty good with the herbs, too...
Sage tea would do well, too...
But almost any hot tea will have some use.
Don't forget chicken broth.
Red pepper really helps.
I don't recall the ingredients at the moment, but one does not have to be a pagan to believe in herbs. All things on this earth were put here for our benefit. The bad thing is that people abuse them.
The GOOD thing is that most of the herbs have no side-effects.
So are "Kitchen Witches". :-)
