Wash the fig leaves and allow them to dry.
Preheat the oven to 200℉. Arrange the fig leaves on a cooling rack set on a baking sheet. Dehydrate in the oven for approximately 30 minutes. Remove from the oven to cool. Crush the leaves with your hands and stores in glass jars. (Alternatively, dehydrate the leaves in a food dehydrator.)
To brew a cup of tea, fill and infuser with a tablespoon of the crushed fig leaves. Immerse in a cup of hot water and let sit for about 5 minutes. Add sweetener if desired.
