RESUMO
Alo vera is a centenary remedy use for minor wounds and burns, but its mechanism of wound healing has not been know since. This article will evaluate and gather evidence of the effectiveness and safety of the use of aloe vera in the treatment of burns. A systematic review was carried out on the databases: MEDLINE, LILACS, DECS, SCIELO, in the last 7 years, with the descriptors: "Aloe", "Burns" and "treatment". 16 articles were found. After using the exclusion criteria; research in non-humans and literature review; 5 articles were selected. The article Teplick et al. (2018) performed an in vitro clinical experiment in A. Vera solution, and demonstrated that there was proliferation and cell migration of human skin fibroblasts and keratinocytes, in addition to being protective in the death of keratonocytes. That is, it accelerates the healing of wounds. Muangman et al. (2016), evaluated 50 patients with 20% of the total body surface area burned with second-degree burns, between 18-60 years old, with half of the group receiving gauze dressings with soft paraffin containing 0.5% chlorhexidine acetate and the other half receiving polyester dressings containing extracts of medicinal plants mainly Aloe Vera. It had positive results, a higher healing speed and shorter hospital stay compared to the control group. Hwang et al. (2015) investigated the antioxidant effects of different extracts from 2,4,6,8,12 months of Aloe Vera. And the 6-month concentrated extract of 0.25 mg / mL had a higher content of flavonoids (9.750 mg catechin equivalent / g extract) and polyphenols (23.375 mg gallic acid equivalent / g extract) and the greater ferric reducing antioxidant power (0.047 mM equivalent ferrous sulfate / mg extract), that is, greater potential for free radical scavenging and also a protective effect against oxidative stress induced by tert-butyl hydroperoxide (t-BHP), suggesting evidence of a bioactive potential of A. vera . However, in the article Kolacz et al. (2014) suggested as an alternative treatment the use of Aloe Vera dressing in combination with honey, lanolin, olive oil, wheat germ oil, marshmallow root, wormwood, comfrey root, white oak bark, lobelia inflata, glycerin vegetable oil, beeswax and myrrh, without obtaining significant and conclusive results that would allow the conventional treatment of burns to be subsidized. Finally, in the article by Zurita and Gallegos (2017), it carried out a descriptive cross-sectional study with 321 people, both sexes between 17-76 years of age, of an inductive nature, exploring the experience of this population and their behavioral attitudes regarding the treatment of dermatoses. Aloe vera had 13.8% cited by individuals in the treatment of acne and 33.6% in the treatment of burns. Even with evidence that suggests the efficacy in the treatment of burns with the use of Aloe Vera extract, further clinical trials with larger sample space on the use of Aloe vera dressings in medium burns are suggested for further conclusions.

Resumo Alo vera é um remédio centenário usado para pequenas feridas e queimaduras, mas seu mecanismo de cicatrização de feridas não foi conhecido desde então. Este artigo avaliará e reunirá evidências da eficácia e segurança do uso de aloe vera no tratamento de queimaduras. Realizada revisão Sistemática nas bases de dados: MEDLINE, LILACS, DECS, SCIELO, nos últimos 7 anos, com os descritores: "Aloe", "Burns" and "treatment". Foram encontrados 16 trabalhos. Após utilizarmos os critérios de exclusão; pesquisa em nao humanos e revisão da literatura ; foram selecionados 5 artigos. O artigo Teplick et al. (2018) realizou um experimento clinico in vitro em solução de A. Vera, e demonstrou que houve proliferação e migração celular de fibroblastos e queratinócitos de pele humana, além de ser protetor na morte de queratonócitos. Ou seja, acelera a cicatrização das feridas. Já Muangman et al. (2016), avaliou 50 pacientes com 20% do total da área superficial corporal queimada com queimaduras de segundo grau, entre 18-60 anos, tendo metade do grupo como controle recebendo curativos de gaze com parafina mole contendo 0,5% acetado de clorexidina e a outra metade recebendo curativos com poliéster contendo extratos de plantas medicinais principalmente Aloe Vera. Teve resultados positivos, uma maior velocidade de cicatrização e menor tempo de internação comparado ao grupo controle. Já Hwang et al. (2015) investigou os efeitos antioxidante de diferentes extratos de 2,4,6,8,12 meses da Aloe Vera. E o extrato com 6 meses concentrado de 0,25 mg/mL teve maior teor de flavanóides (9,750 mg equivalente catequina / g extrato) e polifenóis (23,375 mg equivalente ácido gálico / g extrato) e o maior poder antioxidante redutor férrico (0,047 mM de sulfato ferroso equivalente / extrato mg), ou seja, maior potencial de eliminação de radicais livres e também efeito proteror contra o estresse oxidativo induzido por hidroperóxido de terc-butila (t-BHP), sugerindo indícios de um potencial bioativo da A. vera. Porém, no artigo Kolacz et al. (2014) sugeriu como tratamento alternativo o uso do curativo com Aloe Vera em conjunto de mel, lanolina, azeite de oliva, óleo de gérmen de trigo, raiz de marshmallow, absinto, raiz de confrei, casca de carvalho branco, lobelia inflata, glicerina vegetal, cera de abelha e mirra, não obtendo resultados significativos e conclusivos que permitam subsidiar o tratamento convencional das queimaduras. Por fim, no artigo de Zurita and Gallegos (2017), realizou um estudo descritivo transversal com 321 pessoas, ambos os sexos entre 17-76 anos, de natureza indutiva, explorando a vivência dessa população e suas atitudes comportamentais quanto ao tratamento de dermatoses. Aloe vera teve 13,8% citada pelos indivíduos no tratamento de acne e 33,6% no tratamento de queimaduras. Mesmo tendo evidências que sugerem a eficácia no tratamento de queimaduras com o uso do extrato da Aloe Vera, sugere-se mais ensaios clínicos com espaço amostral maior sobre o uso de curativos de Aloe vera em médio queimados para maiores conclusões.
