Aloe vera gel comes from beneath the layers of Aloe plant leaves which is succulent-like often thought of as cactus leaves.
Aloe vera leaves are filled with thick and gelatinous gel and the aloe vera gel at the center of each leaf is important for medicinal purposes.
Each aloe leaf is divided into four layers, the rind which is the hard greenish gray other protective layer, the sap which is the bitter liquid under the rind that surrounds the gel, the mucilage gel or the inner leaf area and, the inner gel or the gel fillet which contains eight essential amino acids vital to the body.
The inner gel is the one you need for medicinal use.
You should carefully remove any inner leaf and sap thoroughly.
It is a great advantage if you know how to make your own Aloe vera gel especially when you have the plants at home or is planning to grow one.
It will really be helpful for you to able to acquire herbal medicine any time or for your cosmetic needs.
You can make your own gel by:

1. Choose an outer leaf that grows toward the bottom of the plant, provided that it's healthy also.
   Remove it by cutting an angle close to the base of the plant.
   Remember that plants without having leaves growing close to the ground are not mature enough to harvest.
   
2. Once the leaf is cut, place the leaf upright in a container, slightly tilted position.
   Allow the leaf to stay in that position for 10 to 12 minutes for the sap to drain from the leaf.
   
3. Place the aloe vera leaf on a cutting board and cut off the tip of the leaf carefully.
   Cut the pointed rough edges on both side with a very sharp knife making sure that both side of the leaf all the way from the top to bottom were cut.
   
4. Slice the aloe vera leaf lengthwise from the inside to separate the front and the back.
   
5. Seeing the slimy mucilage gel, scoop them out from both side of the leaf.
   Clear the inner gel, something that appears to be more solid.
   You may use spoon for scooping out the gel and you may use a butter knife if the leaf is very large.
   While removing the gel, it is necessary for you to press down lightly but firmly.
   Be careful not to remove the remaining sap.
   
6. Put the aloe vera gel in a plastic food container or glass food container and store it in the refrigerator.
   Choose the container that may help keep out the light like brown or dark green colored container.
