About Aloe vera
Aloe vera is a hardy succulent, easy to grow, cultivated for over 2000 years for the gel in its leaves. Native to arid regions of North Africa and the Arabian Peninsula, it has spread worldwide. It tolerates drought well and thrives on any bright windowsill, both in a greenhouse and indoors, in filtered light or direct sun, whether watered or not.
The gel from the leaves is traditionally used in alternative medicine, both internally and externally. It is applied to the skin for numerous conditions—from minor irritations, mild burns, sunburns, or insect bites to more serious ailments. This guide describes the plant and its cultivation—it does not replace or constitute medical advice.

How to identify edible Aloe vera
Scientific names have changed many times in literature. In practice, it is important to distinguish two common types:
1. Aloe barbadensis type (the line usually used for leaf gel)
Also known as Aloe vera barbadensis, A. barbadensis, A. vera var. miller, etc. All these labels refer, in commerce, to the same line with broad, thick, fleshy, gray-green leaves. The flowers are yellow. Young leaves may have freckles; mature leaves usually have a more uniform, slightly silvery color. This is the most cultivated form for gel.
Aloe barbadensis type: broad, thick, gray-green leaves.
2. Aloe vera var. chinensis
Narrower, more delicate leaves, often freckled even on mature leaves, arranged more disorderly. The flowers are orange. It is more common and more accessible—usually used only externally. Internal consumption can have a strong laxative effect—do not treat it as edible Aloe vera.
Aloe vera var. chinensis: narrower, freckled leaves, orange flowers.
Visual comparison: barbadensis vs chinensis.
Cultivation highlights
The temperatures, watering, and exposure below are approximate values. Pot size, actual sunlight at the window, and substrate affect the drying rate of the substrate. Aloe tolerates drought very well for long periods but does not tolerate excess water at all.
Light, temperature, watering
Light. Grows well in mild direct sun or very strong, partially filtered light. If grown in shade, the plant elongates, leaves become thin/delicate, and it becomes more sensitive to diseases and pests.
Temperature. It is a heat-loving succulent. It tolerates occasional short cold spells down to about -2°C but it is not worth the risk to keep it outside in winter in Romania. Indoors, keep it away from radiators, cold drafts, and very cool windows at night (temperatures near windows are generally lower than in the rest of the room).
Watering. Water when the substrate has dried well, then let excess water drain. Do not leave water in the saucer or decorative pot cover. Water stagnating among roots quickly leads to rot. In a small pot, in strong sun, substrate dries quickly: check more often, do not water on a fixed schedule. Sometimes it is better to forget the plant for a few weeks.
Substrate and pot
Aloe adapts to many mixes, but good performance appears on soil that drains very well, especially when cooler and water evaporates slowly. Indoors, use a substrate for cacti, succulents, and Adenium or a quality flower soil strongly loosened with perlite, pumice, or coarse sand.
Choose a pot with real and generous drainage holes. Add a layer of clay balls, gravel, or pumice at the bottom before adding substrate and replanting an Aloe specimen. A pot just slightly larger than the roots is easier to manage than a huge pot full of wet substrate.
Usage and precautions
Important: this article does not provide medical advice. Do not consume Aloe vera or use it on serious wounds without a doctor's approval, especially if you have allergies, are pregnant, or are undergoing treatment.
- For gel, choose plants at least 2-3 years old, with mature leaves.
- Do not consume freshly purchased plants unless the label clearly states they come from cultivation intended for consumption. Otherwise, keep the plant for a period without chemical treatments before any internal use.
- In the case of Aloe chinensis: laxative effect when consumed; do not confuse it with the barbadensis type.
Frequently asked questions
Why does Aloe rot at the base?
Most often: watering too frequently or substrate that retains water, especially in winter. Let the substrate dry well between waterings.
The leaves are soft and pale. What should I do?
Check the light (too little), water (too much or, rarely, too little), and temperature near the window. Correct one factor at a time.
Can I keep Aloe outside in winter?
In most areas of Romania, Aloe vera should not be treated as a permanent outdoor plant. When temperatures drop, move the plant indoors to a bright place, protected from frost.
