Scientific evidence suggests that aloe vera may be used for the treatment and management of constipation, genital herpes, seborrheic dermatitis and psoriasis, according to Mayo Clinic. It is important to note, however, that there are other studies that contradict these and other supposed benefits that are promoted by proponents of the use of aloe vera as an alternative medicine. For instance, aloe vera taken by mouth has also been linked to hepatitis.
Aloe vera is a short-stemmed succulent plant that has been regarded as a medicinal plant since the 1st century A.D. The plant is cultivated for commercial use for its supposed healing, rejuvenating and soothing properties.
Another well-known benefit of aloe vera is its ability to soothe minor burns and scrapes on the skin. Creams and gels containing aloe vera, or pure aloe vera itself, have been used for thousands of years to heal wounds and aid in all kinds of skin conditions, About.com notes.
While aloe vera may be able to help treat and manage certain medical conditions according to some studies, further research will still be needed to confirm the findings, notes Mayo Clinic.
Apart from those already mentioned, there are also claims that aloe vera can help prevent cancer, cure canker sores and counteract the negative effects of chemotherapy. Scientific evidence in these regards, however, is inconclusive.
Mayo Clinic also warns against the use of aloe vera as an alternative medicine for certain medical conditions because of scientific evidence showing that doing so will have no effect. This includes using aloe vera juice to treat colorectal cancer, heart disease, diaper rash, liver disease, wound salve and HIV infection.
