Aloe vera is one of the most beloved medicinal plants in the world. Whether we talk about skin care, digestion, or burns, the transparent gel from the leaves of this plant has remarkable properties. However, few know that not all aloe plants are good for health; some can even be toxic. Here’s how to identify the beneficial Aloe vera and avoid dangerous confusions.
What is Aloe vera?
Aloe vera is a succulent plant from the Liliaceae family, scientifically known as Aloe barbadensis miller. It is widely cultivated in tropical and subtropical areas but can also be grown easily in pots.
The gel from its leaves is rich in:
- polysaccharides (acemannan)
- vitamins (A, C, E, B1, B2, B3, B6, B12)
- enzymes (bradykininase)
- minerals (zinc, selenium, magnesium)
- essential amino acids
How to Distinguish Aloe vera from Other Species?
There are over 500 species of aloe, but only a few are safe for internal use. Aloe vera (Aloe barbadensis miller) is the safest and most studied. Other species, such as Aloe arborescens or Aloe ferox, may have external uses, but many others contain toxic anthraquinones, especially in the yellow part between the skin and the gel.
Main Differences:
| Characteristic | Aloe vera (barbadensis miller) | Aloe ferox / other species |
|---|---|---|
| Leaf color | Light green, sometimes with white spots | Dark green or gray-green |
| Leaf texture | Soft, succulent, very watery gel | Thicker, with intense yellow latex |
| Leaf length | 30-50 cm | Up to 1 meter |
| Gel taste | Slightly bitter, neutral | Very bitter, sometimes unpleasant |
| Presence of yellow latex | Very low | High (strong laxative effect) |
| Internal use | Safe in small doses | To be avoided (potential toxicity) |
How to Recognize True Aloe vera at Home
