Magical teas are dry herbal mixtures which can be stored for extended periods of time and used when needed. Unlike potions, magical teas are not used during the heat of battle for a quick bonus. Because they take some time to brew, and their effects usually take some time to come to fruition, they are generally used during an adventuring day and sometimes over long periods of time.
An example of a magical tea:
Black Hill Tea
This magical tea is made from a secret collection of herbs and flowers gathered by the monks of the Black Hills. Characters who drink this tea will gain 1d4 hit points over night.
