What we will need: Ginger (1 small piece). Chopped lemons (3 units). Cinnamon (2 stakes). Mint leaves (several). Mineral water (0.75 liters). Preparation and use: The first thing to do is to boil the water. Once at the boiling point, add the lemon, ginger and cinnamon pieces. Let it simmer for 15 to 20 minutes and proceed to filter it with a strainer. We will allow it to cool down a bit and we take that infusion.
