Indications
Aloe vera extract comes from the leaves of the Aloe vera plant. Taken by mouth, it has traditionally been used for constipation, digestive discomfort and as a general tonic. Applied to the skin as a gel, it is traditionally used to soothe minor burns, sunburn, dryness and irritation. Scientific evidence for most of these uses is limited, and it should not be relied on to cure any disease.
How It Works
The clear inner gel contains water, sugars (such as acemannan), vitamins and plant compounds that may moisturise and calm the skin. The yellow layer just under the leaf skin (aloe latex) contains anthraquinones such as aloin, which irritate the bowel and draw water into it, producing a laxative effect. The strength and type of extract vary between products.
Dosage and Administration
Use as directed on the label or by a registered practitioner. Capsules or juice are usually taken once or twice a day with water. Gels are applied thinly to clean skin a few times a day. Do not use laxative-type aloe products by mouth for more than 1 to 2 weeks without medical advice.
Interactions
Oral aloe, especially products containing latex, can cause loss of potassium and may increase the effects of Digoxin and the potassium loss caused by diuretics such as Furosemide or corticosteroids. It may lower blood sugar and add to the effect of diabetes medicines. It can reduce the absorption of other medicines taken at the same time; take them at least 2 hours apart. Do not combine with other laxatives.
Contraindications
Do not take aloe by mouth if you have bowel blockage, inflammatory bowel disease (Crohn’s disease or ulcerative colitis), appendicitis, or stomach pain of unknown cause. Do not use if you are allergic to aloe or to plants of the lily family, such as garlic, onions or tulips.
Side Effects
Possible side effects include:
- Stomach cramps and diarrhoea, especially with latex-containing products
- Low potassium with long-term use, causing weakness or muscle cramps
- Skin redness, itching or burning when applied to the skin
Get urgent medical help for severe or bloody diarrhoea, severe stomach pain, an irregular heartbeat, marked weakness, yellowing of the skin or eyes, or swelling of the face or throat.
Pregnancy and Lactation
Do not take aloe by mouth during pregnancy or breastfeeding, as aloe latex may stimulate the womb and its safety has not been shown. Using aloe gel on small areas of skin is generally considered acceptable, but ask your doctor first.
Precautions and Warnings
Oral aloe is not recommended for children under 12 years. Long-term use of whole-leaf or latex products is not advised. People with kidney, liver or heart disease should ask a doctor before use. Test a small area of skin before applying gel widely, and do not apply to deep wounds or severe burns.
Overdose
Taking too much by mouth may cause severe diarrhoea, stomach cramps, dehydration and low potassium. Stop taking it and seek medical advice, especially if a child has swallowed it.
Therapeutic Class
