Select good quality organic apples, wash them well and slice them (no need to peel). Squeeze the lemon to obtain its juice and mix it with the water. Add the apple slices and cinnamon sticks to the water. Refrigerate for two hours. Optionally, you can leave it overnight to let the cinnamon, apples, and lemon release their active ingredients. Drink a glass shortly before each main meal to enjoy its benefits.
