Stir all ingredients together in a medium size bowl until well-mixed, then store in an airtight container for up to 1 year.
To steep the tea
To steep, bring fresh water to a boil, then remove the kettle from the heat and allow the boiling to come to a stop. Place 1-2 tablespoons of the cold and flu tea blend into a tea strainer in a mug, then pour over the nearly-boiling water, cover with a small plate or other cover, and let steep for 10-15 minutes.
Remove herbs from the tea, then sip as desired, preferably while wrapped in heavy blankets to promote sweating.
Notes
While this nutritive tea can be considered safe during pregnancy, as with all things, it should be drunk in moderation.
