There is little scientific evidence of the effectiveness or safety of Aloe vera extracts for either cosmetic or medicinal purposes. A research study finding positive evidence is frequently contradicted by other studies.[4][5][6][45]

Despite this, the cosmetic and alternative medicine industries regularly make claims regarding the soothing, moisturizing, and healing properties of aloe vera.[4][46]

Two 2009 reviews of clinical studies determined that all were too small and faulty to allow strong conclusions to be drawn.[45][47] One of the reviews found that Aloe has not been proven to offer protection for humans from sunburn.[47]

There is no good evidence aloe vera is of use in treating wounds or burns.[48][49] There is no good evidence that topical application of aloe vera is effective for treating genital herpes or psoriasis.[50] A 2014 Cochrane review found no strong evidence for the value of topical application of aloe vera to treat or prevent phlebitis caused by intravenous infusion.[51]

Aloe vera gel is used commercially as an ingredient in yogurts, beverages, and some desserts,[52][53][54] although at certain high doses, its toxic properties could be severe whether ingested or topically applied.[55] The same is true for aloe latex, which was taken orally for conditions ranging from glaucoma to multiple sclerosis until the FDA required manufacturers to discontinue its use.[56]

Dietary supplement Edit
Aloin, a compound found in the exudate of some Aloe species, was the common ingredient in over-the-counter (OTC) laxative products in the United States until 2002 when the Food and Drug Administration banned it because the companies manufacturing it failed to provide the necessary safety data.[57][58] Aloe vera has potential toxicity, with side effects occurring at some dose levels both when ingested or applied topically.[55] Although toxicity may be less when aloin is removed by processing, Aloe vera that contains aloin in excess amounts may induce side effects.[4][45][59]

Aloe vera juice is marketed to support the health of the digestive system, but there is neither scientific evidence nor regulatory approval to support this claim.[60] The extracts and quantities typically used for such purposes appear to be dose-dependent for toxic effects.[55]

Traditional medicine Edit
Aloe vera is used in traditional medicine as a skin treatment. In Ayurvedic medicine it is called kathalai, as are extracts from agave.[61]:196 for aloe:117 for agave Early records of Aloe vera use appear in the Ebers Papyrus from the 16th century BC,[17]:18 and in Dioscorides' De Materia Medica and Pliny the Elder's Natural History – both written in the mid-first century AD.[17]:20 It is also written of in the Juliana Anicia Codex of 512 AD.[52]:9 The plant is used widely in the traditional herbal medicine of many countries.

Commodities Edit
Aloe vera is used on facial tissues where it is promoted as a moisturizer and anti-irritant to reduce chafing of the nose. Cosmetic companies commonly add sap or other derivatives from Aloe vera to products such as makeup, tissues, moisturizers, soaps, sunscreens, incense, shaving cream, or shampoos.[52] A review of academic literature notes that its inclusion in many hygiene products is due to its "moisturizing emollient effect".[11]

Other potential uses for extracts of Aloe vera include the dilution of semen for the artificial fertilization of sheep, as a fresh food preservative,or for water conservation in small farms.It has also been suggested that biofuels could be obtained from Aloe vera seeds.
