1. Cut the base. Use a sharp knife to make a clean cut near the base. A yellow liquid will come out: Aloin, it's bitter and can act as a laxative!
2. Remove the serrated edges and skin, like in the picture bellow.
3. Take the gel, washed it to remove any extra Aloin. Blend 1/5 Aloe Vera gel with 4/5 of juice or fruits with a spoon of lemon.
Another option is to add some sparkling water with lemon flavor for dilution and makes it tastier.
Drink it every day on an empty stomach and you will see the benefits on your body.
For food consumption:
Take a 2 cm gel, cut in small pieces and put it in a salad or yogurt.
Tip: if you don't like the smell of Aloe Vera you can add lemon and honey for eating, or a drop of your favorite essential oil for your cosmetics.
Warning, don't eat more than 50 g Aloe Vera gel per day.
How to preserve
Keep the leaf in room temperature in a dry and airy place away from the sun. Under a shelf for example. Never in the fridge because it's moist or closed in a cupbord because there is no air. It can be preserved for around 2 to 3 weeks. Actually the leaf is consuming its own gel to survive. When you cut a piece it will heal by itself.
The removed gel can be kept a week in the fridge or frozen for later use. This is better than adding conservatives to preserve it longer.
