Aloe vera: The gel is not the juice

What it is

Two very different things come from the aloe leaf, and confusing them is the most common mistake. The gel, the clear inner pulp, is used on the skin to soothe mild burns and irritation. The latex or dried juice, yellow and taken from the layer under the rind, contains hydroxyanthracene derivatives (such as aloin): it is a stimulant laxative.

As a laxative it has a European monograph for occasional constipation, short term. But in foods and supplements the European Union restricted these derivatives in 2021 over safety concerns. So at the counter, "aloe to drink" always deserves a question: which part of the plant it contains.

How it works

Depending on the part of the leaf:

The GEL adds moisture and has a soothing, cooling effect on irritated skin
The LATEX contains hydroxyanthracenes that stimulate colon movement: it is a stimulant laxative
The evidence for the gel in healing mild burns is modest; it does not replace proper wound care

At the counter

When to recommend it

Mild sunburn and redness, with the gel
Mild skin irritation
Occasional constipation, with the medicine presentation and for a short time
People looking for a soothing after-sun product

When not to

Laxative latex or juice in pregnancy, breastfeeding, under-12s or inflammatory bowel disease
Laxative latex for more than one or two weeks, or with undiagnosed abdominal pain
Infected or deep wounds, and extensive burns or burns with large blisters
Allergy to plants of the aloe family or a previous reaction to the gel

What to say at the counter. For the skin, the clear gel. If you want it to drink, check the label: if it contains aloin or latex it is a laxative, and not for daily use.

Warnings

Important Aloe latex is a stimulant laxative: prolonged use causes potassium loss and laxative dependence.
Important In 2021 the EU restricted aloe hydroxyanthracenes in foods and supplements over safety concerns.
Caution Potassium loss from the laxative can increase digoxin toxicity and adds to diuretics and corticosteroids.
Caution The gel can cause contact dermatitis: test on a small area first.
Worth knowing The latex can turn the urine reddish, which is harmless.

How it is used

On the skin: the gel, in a thin layer, on clean skin without infected open wounds.
As a laxative: only the medicine presentation, for a few days and no more than one or two weeks.
To drink: check that the product contains no latex or aloin.
If a burn has large blisters, is extensive, or is on the face, hands or genitals, refer.

Aloe gel vs aloe latex

Aspect	Gel	Latex or dried juice
Part of the leaf	Clear inner pulp	Yellow layer under the rind
Use	Topical, skin	Oral, laxative
Key components	Polysaccharides, water	Hydroxyanthracenes (aloin)
Long-term use	No relevant problem	No: potassium loss and dependence
In supplements	Allowed	Restricted in the EU since 2021

The gel soothes the skin; the latex is a laxative with limits. Knowing which one the product contains is half the advice.

Self-assessment

Three questions. When you check your answers you will see the explanation for each one.

Which part of aloe is a stimulant laxative? The yellow latex or dried juice, with aloin The clear gel The root
Why is aloe latex not suitable daily for months? Because it causes potassium loss and laxative dependence Because it loses strength in the sun Because it stains the skin
What changed in the European Union in 2021? Aloe gel was banned It was authorised as a skin medicine Aloe hydroxyanthracenes were restricted in foods and supplements
