Few plants are as closely linked to summer as aloe vera. Its thick, spiky leaves sit on windowsills across Georgia, and its cool, clear gel has a long reputation as a companion for skin that has seen a lot of sun. The plant’s story is older than most people realize.
An ancient and much-traveled plant
Aloe vera is a succulent in the same broad family as lilies and asparagus, and most botanists believe it originated on the Arabian Peninsula. From there it traveled with traders across North Africa, the Mediterranean, India and eventually the Americas, thriving wherever the climate was warm and dry.
It appears in some of the oldest medical and cosmetic writings that survive, including texts from ancient Egypt, where it was prized enough to feature in legends about queens and their beauty routines. Greek and Roman writers described it as well. Over the centuries it became a standard plant of apothecary gardens and, much later, a staple of modern lotions and after-sun products.
Gel, latex and what is inside a leaf
Cut an aloe leaf and you will find two different substances. The inner part is a clear, slippery gel that is mostly water. Just under the green rind is a thin layer of yellowish latex that tastes bitter and is not the same thing at all. Skin products and the familiar green bottles are made from the gel.
Because of that difference, it is worth being careful with homegrown aloe. If you want to use fresh gel on your skin, rinse the leaf, let the yellow latex drain away and scoop out only the clear interior. Questions about taking aloe by mouth in any form are a matter for your doctor or pharmacist, not a blog.
Why people reach for it in summer
The appeal of aloe gel is mostly about sensation. Straight from the refrigerator, it feels cool and light on warm skin, absorbs quickly and leaves little residue. Many people enjoy smoothing it over their shoulders or feet after a day at the lake or in the garden. We describe that as a pleasant experience rather than a treatment, because that is what it is.
If your skin is blistered, badly burned, broken or painful, that is not something a plant on the windowsill should handle. Talk to your doctor. Aloe is a comfort, not a cure for anything.
Growing one of your own
Aloe is among the easiest houseplants to keep. It wants bright light, a pot that drains well and far less water than most people give it. Let the soil dry out completely between waterings, keep it out of frost and it will reward you with offsets, the little pups that appear around the base and can be potted up and given to friends.
A plant that has survived thousands of years of human travel, from the deserts of Arabia to a kitchen window in Macon, deserves a little admiration. Give it some sun, forget to water it now and then, and it will be perfectly happy.
