Aloe vera has been prized for its medicinal value since the earliest of times. The ancient Egyptians are believed to have used aloe vera for both external and internal disorders. Since then, the aloe vera plant has been used in a range of applications, from skin conditions to alternative treatments for illnesses related to cancer. Scientific evidence for many applications, however, is lacking. Further, use of aloe vera can lead to allergic reactions.
Uses and Indications
The National Center for Complementary and Alternative Medicine says there are two traditional uses for the aloe vera plant. One is external as a wound treatment, while the other is internal as a laxative treatment. More recently, the aloe vera plant has been used in the treatment of herpes, skin ulcers, dermatitis, mucositis, psoriasis, cancer and type 2 diabetes, according to Medline Plus.
External Symptoms
Certain reactions may indicate an allergy to the aloe vera plant. Typically, aloe vera gel reduces inflammation and skin redness. If you have an allergy to aloe vera, these symptoms will likely be exacerbated, and your rash could spread to other parts of the body. The National Center for Complementary and Alternative Medicine says that such reactions to aloe vera gel are generally uncommon; therefore such an allergy should not be difficult to spot.
Severe Reactions
An allergy to aloe vera can also show up when you consume the leaves or juice. Symptoms might include facial and neck swelling, hives and breathing difficulties. A severe allergy can cause potentially life-threatening anaphylaxis, also known as body shock. In such a case, you may lose consciousness. Suspected anaphylaxis requires emergency treatment in the form of epinephrine injections.
Prevention/Solution
An allergist will look at your skin and ask about your symptoms to make a diagnosis. In addition, you may undergo skin-prick tests to confirm the allergy. During such a test, a small amount of aloe vera extract is applied to the skin. Your allergist will then monitor the area for a reaction. The best form of treatment for an aloe vera allergy is to avoid the plant all together.
Considerations
Medline Plus reports that you are most susceptible to an aloe vera allergy if you also have an allergy to tulips, garlic and onions. Aloe vera should not be taken orally if you are pregnant or breastfeeding. Also keep in mind that oral versions of aloe vera can cause side effects such as diarrhea and abdominal cramps, whether you have an allergy to the plant or not. Ask your doctor before using, especially if you are taking medications.
