Bring 1 gallon of water to a boil in a pot with a lid (or adjust your ratio using the recipe note).
Add 1-2 cups loose leaf herbs/tea leaves to the water and stir into the water.
Remove the pot from heat and cover with a lid.
Allow tea to steep for a few minutes or several hours, depending on preference.
Strain herbs from tea and enjoy warm, cold, over ice, or as popsicles.
Notes
The general rule for making tea is 1 teaspoon - 1 tablespoon + of tea per 1 cup of water. 1 tablespoon + will brew a much stronger and more nutritive cup of tea.
Tea can be brewed for a few minutes or several hours. The longer it is brewed, the stronger the taste and higher the mineral content. Some herbs will create tea that becomes more bitter the longer they are brewed.
My favorite way to make tea is right before bed and allow it to steep overnight.
If you are making a blend of several herbs, simply divide the total amount of tea needed by the amount of herbs being used. For example, if you need 1 cup of tea leaves for brewing 1 gallon of tea, and you are using 4 different herbs, add 1/4 cup of each herb. You might also use more of a sweet herb than a bitter one, especially for children.
