Abstract
BACKGROUND This systematic review and network meta-analysis aimed to assess comparative efficacy and safety of interventions to treat symptomatic, biopsy-proven oral lichen planus (OLP). METHODS Search was conducted for trials published in Medline, Embase and Cochrane Central Register of Controlled Trials. Network meta-analysis was performed on data from randomized controlled trials that assessed efficacy and safety of interventions used in the treatment of OLP. Agents were ranked according to their effectiveness in treatment of OLP based on outcomes using surface under the cumulative ranking [SUCRA]. RESULTS In total, 37 articles were included in the quantitative analysis. Purslane was clinically significant and ranked first in improving clinical symptoms [RR = 4.53; 95% CI: 1.45, 14.11], followed by aloe vera [RR = 1.53; 95% CI: 1.05, 2.24], topical calcineurin [RR = 1.38; 95% CI: 1.06, 1.81] and topical corticosteroid [RR = 1.35 95% CI: 1.05, 1.73]. Topical calcineurin demonstrated the highest incidence of adverse effects [RR, 3.25 [95% CI: 1.19, 8.86. Topical corticosteroids were significant in achieving clinical improvement of OLP with RR1.37 [95% CI: 1.03, 1.81]. PDT [MD = -5.91 [95% CI: -8.15, -3.68] and showed statistically significant improvement in the clinical score for OLP. CONCLUSIONS Purslane, aloe vera and photodynamic therapy appear promising in treatment of OLP. More high-quality trials are recommended for strengthening the evidence. Although topical calcineurin is significantly efficacious in the treatment of OLP, significant adverse effects are a concern for clinical use. Based on the current evidence, topical corticosteroids are recommended for treatment of OLP owing to their predictable safety and efficacy.

It is a plant that has been used since ancient times for the innumerable health benefits associated with it. It is one of the important plants that has its use in conventional medicinal treatments. It is a perennial succulent, drought-tolerant member of the family Asphodelaceae. There are scores of properties associated with the plant that help in curing various forms of human ailments. Extracts and gels obtained from plants have been shown to be wonderful healers of different conditions, mainly various skin problems. Also, this plant is popular in the cosmetics industry. The underlying properties of the plant are now mainly associated with the natural phytochemicals present in the plant. Diverse groups of phytoingredients are found in the plant, including various phenolics, amino acids, sugars, vitamins, and different other organic compounds, too. One of the primary ingredients found in the plant is the aloin molecule. It is an anthraquinone derivative and exists as an isomer of Aloin A and Aloin B. Barbaloin belonging to the first group is a glucoside of the aloe-emodin anthrone molecule. Various types of pharmacological properties exhibited by the plant can be attributed to this chemical. Few significant ones are antioxidant, anti-inflammatory, anti-diabetic, anti-cancer, anti-microbial, and anti-viral, along with their different immunity-boosting actions. Recently, molecular coupling studies have also found the role of these molecules as a potential cure against the ongoing COVID-19 disease. This study comprehensively focuses on the numerous pharmacological actions of the primary compound barbaloin obtained from the Aloe vera plant along with the mechanism of action and the potent application of these natural molecules under various conditions.

Abstract
Cryptosporidiosis has been considered as a serious diarrheal disease, especially in immunodeficient patients, where they failed to clear the infection leading to several consequences of infection (i.e death). The role of cell mediated immunity in clearing the infection was demonstrated by the increased susceptibility of HIV/AIDS patients to infection. To date, no specific treatment has been proven for cryptosporidiosis in immunodeficient patients. The study aimed to evaluate the efficacy of Aloe vera gel for the treatment of cryptosporidiosis in immunocompetent and dexamethasone immunosuppressed mice in comparison to that of nitazoxanide. Mice were orally administrated with Aloe vera gel, in a daily dose of 250 mg/L in drinking water, for 14 consecutive days post infection. Parasitological, molecular and immunological measurements were recorded on the 7th, 14th, 21st and 32nd days post infection. Our in vitro results showed that 250 mg/L of prepared gel achieved the highest parasitic reduction. The body weights of Aloe vera treated mice on the 21st and 32nd day post infection, either in immunocompetent or immunosuppressed groups, were nearly the same as those of their corresponding control groups. Aloe vera gel succeeded in clearing cryptosporidiosis with a percent reduction of 100% in immunocompetent mice and 99.67% in immunosuppressed mice. The anti-inflammatory effect of Aloe vera reduced the levels of IFN-γ, IL-4, -6 and -17. The success of Aloe vera gel, in clearing cryptosporidiosis in immunosuppressed mice, was obvious either from the reduction of Cryptosporidium DNA or the oocysts in stool samples; and from the improvement of histopathological sections.

Abstract
With an increasing life expectancy and aging population, orthopedic defects and bone graft surgeries are increasing in global prevalence. Research to date has advanced the understanding of bone biology and defect repair mechanism, leading to a marked success in the development of synthetic bone substitutes. Yet, the quest for functionalized bone grafts prompted the researchers to find a viable alternative that regulates cellular activity and supports bone regeneration and healing process without causing serious side-effects. Recently, researchers have introduced natural medicinal compounds (NMCs) in bone scaffold that enables them to release at a desirable rate, maintains a sustained release allowing sufficient time for tissue in-growth, and guides bone regeneration process with minimized risk of tissue toxicity. According to World Health Organization (WHO), NMCs are gaining popularity in western countries for the last two decades and are being used by 80% of the population worldwide. Compared to synthetic drugs, NMCs have a broader range of safety window and thus suitable for prolonged localized delivery for bone regeneration. There is limited literature focusing on the integration of bone grafts and natural medicines that provides detailed scientific evidences on NMCs, their toxic limits and particular application in bone tissue engineering, which could guide the researchers to develop functionalized implants for various bone disorders. This review will discuss the emerging trend of NMC delivery from bone grafts, including 3D-printed structures and surface-modified implants, highlighting the significance and potential of NMCs for bone health, guiding future paths toward the development of an ideal bone tissue engineering scaffold. STATEMENT OF SIGNIFICANCE: To date, additive manufacturing technology provids us with many advanced patient specific or defect specific bone constructs exhibiting three-dimensional, well-defined microstructure with interconnected porous networks for defect-repair applications. However, an ideal scaffold should also be able to supply biological signals that actively guide tissue regeneration while simultaneously preventing post-implantation complications. Natural biomolecules are gaining popularity in tissue engineering since they possess a safer, effective approach compared to synthetic drugs. The integration of bone scaffolds and natural biomolecules exploits the advantages of customized, multi-functional bone implants to provide localized delivery of biochemical signals in a controlled manner. This review presents an overview of bone scaffolds as delivery systems for natural biomolecules, which may provide prominent advancement in bone development and improve defect-healing caused by various musculoskeletal disorders.

Abstract
INTRODUCTION Oral submucous fibrosis (OSMF) is a potentially malignant disorder with a high rate of malignant transformation. It is associated with chewing of areca nut and tobacco products with a high global prevalence, particularly in the southeast Asian countries. A wide range of treatment modalities are available, ranging from corticosteroids, antioxidants, nutritional supplements to herbal medicines but lacks a reliable treatment regimen. AIM This systematic review will comprehensively analyze the medicinal treatment for OSMF from 2011 to 2020, apprise the literature with new clinical studies, and initiate a discussion about other potential medicines. MATERIAL AND METHODS A comprehensive electronic search was conducted in Pubmed, Scopus, and other databases from January 2011 to June 2020 according to the PRISMA guidelines, to identify all the clinical studies for the medicinal management of OSMF with definite keywords and defined criteria. RESULTS Among the thirty-two included clinical studies 23 were randomized controlled studies and 9 were case-control studies. The treatment outcomes were diverse, and the majority of the studies showed improvement in the subjective signs and symptoms of OSMF. Only a few studies noticed the side effects. CONCLUSION No single treatment modality is effective in the management of OSMF. The concurrent use of triple therapy is efficacious. The naturally occurring herbal medicines have an immense potential in the management of OSMF. Therefore, high-quality, longitudinal, multi-center randomized controlled trials with larger samples need to be conducted to further assess the efficacy of various medicinal formulations in conjunction with physiotherapy in the management of OSMF.

Abstract
Background Acute radiation-induced proctitis (ARP) is the most common side effect following radiotherapy for malignant pelvic disease. This study evaluated the efficacy of Aloe vera ointment in prevention of ARP. Methods Forty-two patients receiving external-beam radiotherapy (RT) for pelvic malignancies were randomized to receive either Aloe vera 3% or placebo topical ointment during radiotherapy for 6 weeks. These patients were evaluated based on the severity (grade 0–4) of the following symptoms weekly: rectal bleeding, abdominal/rectal pain, diarrhea, or fecal urgency. RTOG acute toxicity criteria and psychosocial status of the patients were also recorded weekly. Lifestyle impact of the symptoms, and quantitative measurement of C-reactive protein (CRP), an indicator of systemic inflammation, were also measured. Results The results of present study demonstrated a significant preventive effect for Aloe vera in occurrence of symptom index for diarrhea (p < 0.001), rectal bleeding (p < 0.001), and fecal urgency (p = 0.001). The median lifestyle score improved significantly with Aloe vera during RT (p < 0.001). Intervention patients had a significant lower burden of systemic inflammation as the values for quantitative CRP decreased significantly over 6 weeks of follow-up (p = 0.009). Conclusion This study showed that Aloe vera topical ointment was effective in prevention of symptoms of ARP in patients undergoing RT for pelvic cancers. Trial registration IRCT201606042027N6.

Abstract
Irritable bowel syndrome (IBS) is a well diagnosed disease, thoroughly attributed to series of symptoms criteria that embrace a broad range of abdominal complainers. Such criteria help to diagnosis the disease and can guide controlled clinical trials to seek new therapeutic agents. Accordingly, a verity of mechanisms and pathophysiological conditions including inflammation, oxidative stress, lipid peroxidation and different life styles are involved in IBS. Predictably, diverse therapeutic approaches are available and prescribed by clinicians due to major manifestations (i.e., diarrhea-predominance, constipation-predominance, abdominal pain and visceral hypersensitivity), psychological disturbances, and patient preferences between herbal treatments versus pharmacological therapies, dietary or microbiological approaches. Herein, we gathered the latest scientific data between 1973 and 2019 from databases such as PubMed, Google Scholar, Scopus and Cochrane library on relevant studies concerning beneficial effects of herbal treatments for IBS, in particular polyphenols. This is concluded that polyphenols might be applicable for preventing IBS and improving the IBS symptoms, mainly through suppressing the inflammatory signaling pathways, which nowadays are known as novel platform for the IBS management.

Abstract
Background:
Aloe vera, a plant belonging to the family Xanthorrhoeaceae, has received
special interest in recent years, not only for the commercial importance of its derivatives, but also because
of the identification of new molecules from this plant. The latter may provide a scientific support
for ethnobotany, which has been beneficial to mankind for centuries.
Objective:
Recently, the pharmacological activity of proteins derived from natural sources, including
plants, is being explored. We report on the extraction and identification of proteins from A. vera with
antimicrobial activity.
Results:
The protein extract (yield, 0.15%) contained 15 peptides or proteins, whose sequences were
associated with membrane proteins, enzymes, and proteins involved in stress tolerance and defense
against pathogens. The latter is consistent with the previously reported antimicrobial activity of an
A. vera protein extract.

Abstract
In a previous study, the oral administration of an Aloe vera whole leaf extract induced dose-related mucosal and goblet cell hyperplasia in the rat colon after 13 weeks and colon cancer after 2 years. The primary goal of this study was to determine whether or not the administration of aloin, a component of the Aloe vera plant leaf, would replicate the pathophysiological effects that were observed in rats in the previous study with an Aloe vera whole leaf extract. Groups of 10 male F344/N rats were administered aloin at 0, 6.95, 13.9, 27.8, 55.7, 111, 223, and 446 mg/kg drinking water for 13 weeks. At the end of study, rat feces were collected, and the composition of fecal bacteria was investigated by next generation sequencing of the PCR-amplified V3/V4 region of the 16S rRNA gene. At necropsy, blood was collected by cardiac puncture and organs and sections of the large intestine were collected for histopathology. Aloin induced dose-related increased incidences and severities of mucosal and goblet cell hyperplasia that extended from the cecum to the rectum, with increased incidences and severities detected at aloin doses ≥55.7 mg/kg drinking water. Analysis of the 16S rRNA metagenomics sequencing data revealed marked shifts in the structure of the gut microbiota in aloin-treated rats at each taxonomic rank. This study highlights the similarities in effects observed for aloin and the Aloe vera whole leaf extract, and points to a potential mechanism of action to explain the observed pathological changes via modulation of the gut microbiota composition.

Abstract
Individuals living with an ostomy may suffer from a variety of peri-stomal skin complications related to the use of their stoma appliance or accessories. These conditions can be serious enough to significantly impact on a patient's quality of life and may result in severe clinical complications (such as infection). This article is a review of the literature with the objective of investigating and presenting evidence for the well-documented use of aloe vera in the prevention of skin conditions similar to those seen in peri-stomal skin complications. An exploration for the potential use of aloe vera directly or indirectly (as an adjunct to medical devices such as wafers) in stoma patients is presented with the view that this use may be beneficial in the prevention of such peri-stomal skin complications.

Abstract
Aloe vera, also referred as Aloe barbadensis Miller, is a succulent plant widely used for biomedical, pharmaceutical and cosmetic applications. Aloe vera has been used for thousands of years. However, recent significant advances have been made in the development of aloe vera for tissue engineering applications. Aloe vera has received considerable attention in tissue engineering due to its biodegradability, biocompatibility, and low toxicity properties. Aloe vera has been reported to have many biologically active components. The bioactive components of aloe vera have effective antibacterial, anti-inflammatory, antioxidant, and immune-modulatory effects that promote both tissue regeneration and growth. The aloe vera plant, its bioactive components, extraction and processing, and tissue engineering prospects are reviewed in this article. The use of aloe vera as tissue engineering scaffolds, gels, and films is discussed, with a special focus on electrospun nanofibers.

Abstract
Objective: To provide an overview of basic information required by pharmacists to advise patients on the proper use of selected herbs and phytomedicines (“dietary supplements”) as therapeutic agents. Data Sources: The vast literature on this topic in the English, German, and French languages has been researched by the author over a period of many years. Databases that were used include NAPRALERT and MEDLINE. Study Selection: Articles and books dealing with the current popularity of botanical medicine and with laws and regulations covering so-called dietary supplements, as well as information on selected toxic herbs and a few of the most popular beneficial herbs used for treating common ailments and syndromes. Data Synthesis: Studies suggest that many herbal products currently available are both safe and effective drugs. A few products on the US market are definitely unsafe for human consumption and use. Conclusions: The increasing popularity of botanicals, coupled with regulations that prohibit definitive labeling, requires pharmacists to acquire accurate information based on scientifically and clinically acceptable data to advise patients on their use. Useful remedies for several common ailments and information concerning their safety and usefulness provide a starting point for an understanding of this complex field.

Abstract
BACKGROUND Oral submucous fibrosis is a chronic disease, treatment of which has largely been symptomatic. Aloe vera has immunomodulatory, anti-inflammatory, wound healing, antioxidant, and antineoplastic activities. All such properties of aloe vera suggest the possibility of its use in the management of oral submucous fibrosis. METHODS Seventy-four patients of oral submucous fibrosis were randomly divided into 2 groups. Group A patients were treated with systemic (juice) and topical aloe vera (gel) for 3 months. Group B patients were treated with intralesional injection of hydrocortisone and hyaluronidase for 6 weeks with antioxidant supplements for 3 months. Patients were assessed for reduction in burning sensation and increase in mouth opening, cheek flexibility, and tongue protrusion at an interval of 1, 2, and 3 months. RESULTS Both the groups showed statistically significant improvements in all the study parameters at the end of study period (P < 0.001). The clinical response to aloe vera was comparable to that of intralesional injections of hydrocortisone and hyaluronidase with antioxidant supplementation. CONCLUSION The study concludes that aloe vera can be an alternative, safe, and effective treatment regime in the management of oral submucous fibrosis. Long-term follow-up studies with larger sample size are recommended.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tuberculosis (TB) caused by Mycobacterium tuberculosis remains an ongoing threat to human health. Several medicinal plants are used traditionally to treat tuberculosis in Ghana. The current study was designed to investigate the antimycobacterial activity and cytotoxicity of crude extracts from five selected medicinal plants. MATERIAL AND METHODS The microplate alamar blue assay (MABA) was used for antimycobacterial studies while the CellTiter 96® AQueous Assay, which is composed of solutions of a novel tetrazolium compound [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt; MTS] and an electron coupling reagent (phenazine methosulfate) PMS, was used for cytotoxic studies. Correlation coefficients were used to compare the activity of crude extracts against nonpathogenic strains and the pathogenic Mycobacterium tuberculosis subsp.tuberculosis. RESULTS Results of the MIC determinations indicated that all the crude extracts were active on all the three tested mycobacterial strains. Minimum inhibitory concentration values as low as 156.3µg/mL against M. tuberculosis; Strain H37Ra (ATCC® 25,177™) were recorded from the leaves of Solanum torvum Sw. (Solanaceae). Cytotoxicity of the extracts varied, and the leaves from S. torvum had the most promising selectivity index. Activity against M. tuberculosis; Strain H37Ra was the best predictor of activity against pathogenic Mycobacterium tuberculosis subsp.tuberculosis (correlation coefficient=0.8). CONCLUSION The overall results of the present study provide supportive data on the use of some medicinal plants for tuberculosis treatment. The leaves of Solanum torvum are a potential source of anti-TB natural products and deserve further investigations to develop novel anti-TB agents against sensitive and drug resistant strains of M. tuberculosis.

Abstract
The current study investigated the effects of dietary Aloe vera on plasma lipid profile status, antioxidant, and hepatoprotective enzyme activities of GIFT-tilapia juveniles under Streptococcus iniae challenge. Five dietary groups were designed including a control and 100 % Aloe powder incorporated into a tilapia feed at 0.5, 1, 2, and 4 %/kg feed, which were administered for 8 weeks. Fish fed dietary Aloe at 4 %/kg feed significantly reduced in total cholesterol, while triacylglycerol reduced (P < 0.05) in those fed 0.5, 2, and 4 % Aloe/kg feed compared to unsupplemented ones. High-density lipoprotein was significantly elevated in fish fed 0.5 and 1 % Aloe/kg feed compared to unsupplemented ones, and no significant changes (P > 0.05) were noted in low-density lipoprotein among test groups. Furthermore, high activities of superoxide dismutase, catalase, and glutathione peroxide in liver tissues were observed in Aloe-supplemented fish compared to unsupplemented ones, before and after S. iniae challenge (7.7 × 10(6) CFU cells/mL). Variations were also noted in malondialdehyde activity throughout the trial, but no significant difference (P > 0.05) was observed between groups. Meanwhile, Aloe-supplemented fish reduced serum aspartate and alanine aminotransferase (AST and ALT) activities before and after challenge. Based on the second-order polynomial regression analysis, dietary Aloe inclusion levels less than or equal to 1.88, 1.86, and 2.79 %/kg feed were determined to be suitable in improving plasma lipid profile status, antioxidant, and hepatoprotective enzyme activities in GIFT-tilapia in this study, respectively. Thus, A. vera extracts may be recommended as a tilapia feed supplement to enhance fish antioxidant and hepatoprotective capacities, especially during disease outbreaks.

Abstract
Aloe vera is the oldest medicinal plant ever known and the most applied medicinal plant worldwide. The purpose of this study was to prepare polyamide nanocapsules containing A. vera L. by an emulsion diffusion technique with in vivo studies. Diethyletriamine (DETA) was used as the encapsulating polymer with acetone ethyl acetate and dimethyl sulfoxide (DMSO) as the organic solvents and Tween and gelatin in water as the stabilizers. Sebacoyl chloride (SC) monomer, A. vera L. extract, and olive oil were mixed with the acetone and then water containing DETA monomer was added to the solution using a magnetic stirrer. Finally, the acetone was removed under vacuum, and nanocapsules were obtained using a freeze drier. This study showed that the size of the nanocapsule depends on a variety of factors such as the ratio of polymer to oil, the concentration of polymers, and the plant extract. The first sample is without surfactant and the size of nanocapsules in the sample is 115 nm. By adding surfactant, nanocapsules size was reduced to 96 nm. Nanocapsules containing A. vera were administered to rats and the effects were compared with a normal control group. The results showed that in the A. vera group, the effect is higher. The nanocapsules were identified by scanning electron microscopy (SEM), zeta potential sizer (ZPS), and Fourier-transform infrared spectroscopy (FT-IR).

Abstract
BACKGROUND Up to 80% of hospitalised patients receive intravenous therapy at some point during their admission. About 20% to 70% of patients receiving intravenous therapy develop phlebitis. Infusion phlebitis has become one of the most common complications in patients with intravenous therapy. However, the effects of routine treatments such as external application of 75% alcohol or 50% to 75% magnesium sulphate (MgSO4) are unsatisfactory. Therefore, there is an urgent need to develop new methods to prevent and alleviate infusion phlebitis. OBJECTIVES To systematically assess the effects of external application of Aloe vera for the prevention and treatment of infusion phlebitis associated with the presence of an intravenous access device. SEARCH METHODS The Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator (TSC) searched the Specialised Register (last searched February 2014) and CENTRAL (2014, Issue 1). In addition the TSC searched MEDLINE to week 5 January 2014, EMBASE to Week 6 2014 and AMED to February 2014. The authors searched the following Chinese databases until 28 February 2014: Chinese BioMedical Database; Traditional Chinese Medical Database System; China National Knowledge Infrastructure; Chinese VIP information; Chinese Medical Current Contents; Chinese Academic Conference Papers Database and Chinese Dissertation Database; and China Medical Academic Conference. Bibliographies of retrieved and relevant publications were searched. There were no restrictions on the basis of date or language of publication. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-randomised controlled trials (qRCTs) were included if they involved participants receiving topical Aloe vera or Aloe vera-derived products at the site of punctured skin, with or without routine treatment at the same site. DATA COLLECTION AND ANALYSIS Two review authors independently extracted the data on the study characteristics, description of methodology and outcomes of the eligible trials, and assessed study quality. Data were analysed using RevMan 5.1. For dichotomous outcomes, the effects were estimated by using risk ratio (RR) with its 95% confidence interval (CI). For continuous outcomes, mean differences (MD) with 95% CIs were used to estimate their effects. MAIN RESULTS A total of 43 trials (35 RCTs and eight qRCTs) with 7465 participants were identified. Twenty-two trials with 5546 participants were involved in prevention of Aloe vera for phlebitis, and a further 21 trials with 1919 participants were involved in the treatment of phlebitis. The included studies compared external application of Aloe vera alone or plus non-Aloe vera interventions with no treatment or the same non-Aloe vera interventions. The duration of the intervention lasted from one day to 15 days. Most of the included studies were of low methodological quality with concerns for selection bias, attrition bias, reporting bias and publication bias.The effects of external application of fresh Aloe vera on preventing total incidence of phlebitis varied across the studies and we did not combine the data. Aloe vera reduced the occurrence of third degree phlebitis (RR 0.06, 95% CI 0.03 to 0.11, P < 0.00001) and second degree phlebitis (RR 0.18, 95% CI 0.10 to 0.31, P < 0.00001) compared with no treatment. Compared with external application of 75% alcohol, or 33% MgSO4 alone, Aloe vera reduced the total incidence of phlebitis (RR 0.02, 95% CI 0.00 to 0.28, P = 0.004 and RR 0.43, 95% CI 0.24 to 0.78, P = 0.005 respectively) but there was no clear evidence of an effect when compared with 50% or 75% MgSO4 (total incidence of phlebitis RR 0.41, 95% CI 0.16 to 1.07, P = 0.07 and RR 1.10 95% CI 0.54 to 2.25, P = 0.79 respectively; third degree phlebitis (RR 0.28, 95% CI 0.07 to 1.02, P = 0.051 and RR 1.19, 95% CI 0.08 to 18.73, P = 0.9 respectively; second degree phlebitis RR 0.68, 95% CI 0.21 to 2.23, P = 0.53 compared to 75% MgSO4) except for a reduction in second degree phlebitis when Aloe vera was compared with 50% MgSO4 (RR 0.26, 95% CI 0.14 to 0.50, P < 0.0001).For the treatment of phlebitis, Aloe vera was more effective than 33% or 50% MgSO4 in terms of both any improvement (RR 1.16, 95% CI 1.09 to 1.24, P < 0.0001 and RR 1.22, 95% CI 1.16 to 1.28, P < 0.0001 respectively) and marked improvement of phlebitis (RR 1.97, 95% CI 1.44 to 2.70, P < 0.001 and RR 1.56, 95% CI 1.29 to 1.87, P = 0.0002 respectively). Compared with 50% MgSO4, Aloe vera also improved recovery rates from phlebitis (RR 1.42, 95% CI 1.24 to 1.61, P < 0.0001). Compared with routine treatments such as external application of hirudoid, sulphonic acid mucopolysaccharide and dexamethasone used alone, addition of Aloe vera improved recovery from phlebitis (RR 1.75, 95% CI 1.24 to 2.46, P = 0.001) and had a positive effect on overall improvement (marked improvement RR 1.26, 95% CI 1.09 to 1.47, P = 0.0003; any improvement RR 1.23, 95% CI 1.13 to 1.35, P < 0.0001). Aloe vera, either alone or in combination with routine treatment, was more effective than routine treatment alone for improving the symptoms of phlebitis including shortening the time of elimination of red swelling symptoms, time of pain relief at the location of the infusion vein and time of resolution of phlebitis. Other secondary outcomes including health-related quality of life and adverse effects were not reported in the included studies. AUTHORS' CONCLUSIONS There is no strong evidence for preventing or treating infusion phlebitis with external application of Aloe vera. The current available evidence is limited by the poor methodological quality and risk of selective outcome reporting of the included studies, and by variation in the size of effect across the studies. The positive effects observed with external application of Aloe vera in preventing or treating infusion phlebitis compared with no intervention or external application of 33% or 50% MgSO4 should therefore be viewed with caution.

Abstract
Aloe barbadensis Miller (Aloe vera) is an herbal remedy promoted to treat a variety of illnesses; however, only limited data are available on the safety of this dietary supplement. Drinking water exposure of F344/N rats and B6C3F1 mice to an Aloe vera whole-leaf extract (1, 2, and 3%) for 13 weeks resulted in goblet cell hyperplasia of the large intestine in both species. Based upon this observation, 2-year drinking water studies were conducted to assess the carcinogenic potential of an Aloe vera whole-leaf extract when administered to F344/N rats (48 per sex per group) at 0.5, 1, and 1.5%, and B6C3F1 mice (48 per sex per group) at 1, 2, and 3%. Compared with controls, survival was decreased in the 1.5% dose group of female rats. Treatment-related neoplasms and nonneoplastic lesions in both species were confined primarily to the large intestine. Incidences of adenomas and/or carcinomas of the ileo-cecal and cecal-colic junction, cecum, and ascending and transverse colon were significantly higher than controls in male and female rats in the 1 and 1.5% dose groups. There were no neoplasms of the large intestine in mice or in the 0 or 0.5% dose groups of rats. Increased incidences of mucosa hyperplasia of the large intestine were observed in F344/N rats, and increased incidences of goblet cell hyperplasia of the large intestine occurred in B6C3F1 mice. These results indicate that Aloe vera whole-leaf extract is an intestinal irritant in F344/N rats and B6C3F1 mice and a carcinogen of the large intestine in F344/N rats.

Abstract
The bio-efficacy of Aloe vera leaf extract and bacterial insecticide, Bacillus sphaericus larvicidal activity was assessed against the first to fourth instars larvae of Aedes aegypti, under the laboratory conditions. The plant material was shade dried at room temperature and powdered coarsely. A. vera and B. sphaericus show varied degrees of larvicidal activity against various instars larvae of A. aegypti. The LC50 of A. vera against the first to fourth instars larvae were 162.74, 201.43, 253.30 and 300.05 ppm and the LC90 442.98, 518.86, 563.18 and 612.96 ppm, respectively. B. sphaericus against the first to fourth instars larvae the LC50 values were 68.21, 79.13, 93.48, and 107.05 ppm and the LC90 values 149.15, 164.67, 183.84, and 201.09 ppm, respectively. However, the combined treatment of A. vera + B. sphaericus (1:2) material shows highest larvicidal activity of the LC50 values 54.80, 63.11, 74.66 and 95.10 ppm; The LC90 values of 145.29, 160.14, 179.74 and 209.98 ppm, against A. aegypti in all the tested concentrations than the individuals and clearly established that there is a substantial amount of synergist act. The present investigation clearly exhibits that both A. vera and B. sphaericus materials could serve as a potential larvicidal agent. Since, A. aegypti is a container breeder vector mosquito this user and eco-friendly and low-cost vector control strategy could be a viable solution to the existing dengue disease burden. Therefore, this study provides first report on the mosquito larvicidal activity the combined effect of A. vera leaf extract and B. sphaericus against as target species of A. aegypti.

Abstract
The present study was undertaken to determine the optimum effective dose, dose reduction factor (DRF) and possible mechanism of action of Aloe gel. Three different doses of gel (250, 500 and 750 mg/kg body weight) were tested against 8 Gy induced damage in Swiss albino mice. A dose of 750 mg/kg body weight of Aloe was found the most effective while, 250 mg/kg body weight was the least effective in providing protection, as observed in the form of higher concentrations of blood GSH and vitamin C and lower level of serum LPO than irradiated animals at 1h post irradiation and higher percent of survivors up to day 30 post irradiation. Treatment of mice with Aloe before irradiation with different doses of gamma radiation (6-12 Gy) delayed the onset and reduced the severity of signs of radiation sickness. The LD(50/30) was calculated as 6.77 and 10 Gy for untreated irradiated and Aloe treated irradiated animals, respectively and its dose reduction factor was also calculated as 1.47. Aloe gel scavenged the free radicals, DPPH•, ABTS(+•) and NO in a concentration dependent manner in vitro and therefore, scavenging of free radicals seems to be its important mechanism of action.

Abstract
BACKGROUND Different treatments have been used in application to symptomatic oral lichen planus (OLP), with variable results, perhaps caused by the refractory nature of the disease. The objective of this study was to evaluate the efficacy of the topical application of aloe vera (AV) in OLP compared with placebo. METHODS A total of 64 patients with OLP were randomized in a double-blind study to either AV (32 patients) or placebo (32 patients), at a dose of 0.4 ml (70% concentration) three times a day. A Visual Analog Scale was used for rating pain, with the application of a clinical scale for scoring the lesions, the Oral Health Impact Profile 49 (OHIP-49), and the Hospital Anxiety-Depression (HAD) scale. The patients were evaluated after 6 and 12 weeks. RESULTS No statistically significant differences were recorded between both groups in relation to pain after 6 and 12 weeks. In the AV group, complete pain remission was achieved in 31.2% of the cases after 6 weeks, and in 61% after 12 weeks. In the placebo group, these percentages were 17.2% and 41.6%, respectively. There were no adverse effects in any of the groups. In relation to quality of life, significant differences were observed between the two groups in the psychological disability domain and total OHIP-49 score. CONCLUSION The topical application of AV improves the total quality of life score in patients with OLP.

Abstract
1Aloe-Barbadensis Mill (Liliaceae) is used in the traditional medicine of Mexico and other countries for anti-inflammatory and cosmetic purposes (Diez-Martinez 1981, Grindlay and Reynolds 1986). Two components are obtained from the fresh leaves of Aloe-Barbadensis, a bitter yellow juice (exudate), which drains from the transversally cut leaves used as a laxative (Ishii et al 1990) and a mucilaginous gel from leaf parenchyma, which has been used as a remedy for a variety of pathological states such as arthritis, gout, acne, dermatitis, burns and peptic ulcers induced by epithelial alterations (Cap-passo and Ganginella 1997, Reynolds and Dweek 1999). The aim of this study is to evaluate efficacy of Aloe-Vera gel as a healing agent in an endodontic procedure called pulpotomy. Fifteen primary molars were treated for pulpotomy using ‘Aloe-Vera gel’. Patients were recalled after 1 month to check for any clinical symptoms. None of the patients reported with clinical symptoms of pain, mobility, abscess and histopathological evaluation done following extraction after 2 months showed positive signs of healing.

Abstract
Frostbite is frequently seen in high altitude climbers. Many Sherpas, members of an ethnic community living high in the Himalayas in Nepal, help the climbers as a guide or an assistant. They often seem to undertake few precautionary measures thus suffer more from frostbite. A young Sherpa, who had reached the top of Mt Kanchenjunga in March 2009, suffered from deep frostbite in his fingers. Fortunately, he recovered well with generous treatment. Though there is no evidence whether Sherpas are more or less prone to frostbite, simple techniques for adequate prevention of hypoxia, hypothermia and dehydration will benefit any climber to the high altitudes.

Abstract
The main scientific discoveries on Aloe vera published mainly in the last three decades are presented in this work. After describing Aloe from a botanical point of view, the papers related with the chemical composition of different parts of the leaf of Aloe, particularly those in which the gel is described and are presented in a synthetic manner. The chemical analyses reveal that Aloe gel contains mannose polymers with some glucose and other sugars, among which the most important is Acemannan. Besides these, other components such as glycoproteins, enzymes, amino acids, vitamins, and minerals are described. Different factors also affecting the chemical composition of the gel, such as species and variety, climatic and soil conditions, cultivation methods, processing and preservation, are enumerated and discussed. On the other hand, the main therapeutic applications have been revised and the possible damaging effects of Aloe are also commented upon. A special emphasis is placed on the biologically active compounds or groups of compounds responsible for the therapeutic applications and which are their action mechanisms. The paper concludes that more research is needed to confirm the therapeutic and beneficial effects and to definitively clarify the myth surrounding Aloe vera. A general view on the problem of the commercialization and establishment of the quality and safety of Aloe products in the food industry has been offered here. The main points and European regulations that need to be considered regarding the quality control of prepared Aloe products are presented in this paper.

Abstract
Abstract
Oxidative stress is currently suggested as a mechanism underlying diabetes and diabetic-related complications. Oxidative stress results from an imbalance between radical-generating and radical-scavenging systems. Many secondary plant metabolites have been reported to possess antioxidant activity. This study was designed to evaluate the potential antioxidative activity of the ethanolic extract from Aloe vera leaf gel in the plasma and pancreas of streptozotocin (STZ)-induced diabetic rats. Glibenclamide was used as a standard reference drug. Oral administration of ethanolic extract at a concentration of 300 mg kg−1 body weight for 21 days resulted in a significant reduction in fasting blood glucose, thiobarbituric acid reactive substances, hydroperoxides and alpha-tocopherol and significant improvement in ascorbic acid, reduced glutathione and insulin in the plasma of diabetic rats. Similarly, the treatment also resulted in a significant reduction in thiobarbituric acid reactive substances, hydroperoxides, superoxide dismutase, catalase and glutathione peroxidase and significant improvement in reduced glutathione in the pancreas of STZ-induced diabetic rats when compared with untreated diabetic rats. The ethanolic extract appeared to be more effective than glibenclamide in controlling oxidative stress. Thus, this study confirms the ethnopharmacological use of Aloe vera in ameliorating the oxidative stress found in diabetes.

Abstract
The radioprotective effect of the Aloe vera leaf extract was studied in Swiss
albino mice against radiation-induced changes in the liver. The mice were
treated with 1000 mg/kg of body weight orally, once a day for 15 consecutive
days, before exposure to a single dose of gamma radiation (6 Gy), half an
hour after the last administration. The irradiation of mice caused a
significant elevation in lipid peroxidation followed by a decrease in
glutathione, acid phosphatase and alkaline phosphatase. The treatment of mice
before irradiation elevated the glutathione, acid phosphatase and alkaline
phosphatase, and was accompanied by a decline in lipid peroxidation. Recovery
and regeneration from radiation damage were faster in pretreated animals than
the animals in the irradiation-only group. The data clearly indicate that the
Aloe vera leaf extract significantly reduced the deleterious effects of
radiation on the liver and it could be a useful agent in reducing the side
effects of therapeutic radiation.

Abstract
BACKGROUND Topical aloe vera (AV) has been used to treat various skin conditions, including psoriasis, with good results. OBJECTIVES This study aims to compare the efficacy of AV and 0.1% triamcinolone acetonide (TA) in mild to moderate plaque psoriasis. METHODS A randomized, comparative, double-blind, 8-week study was designed. Eighty patients randomly received AV or 0.1% TA cream and their clinical response were evaluated using the Psoriasis Area Severity Index (PASI) and the Dermatology Life Quality Index (DLQI). RESULTS After 8 weeks of treatment, the mean PASI score decreased from 11.6 to 3.9 (-7.7) in the AV group and from 10.9 to 4.3 (-6.6) in the TA group. Between-group difference was 1.1 (95% confidence interval -2.13, -0.16, P = 0.0237). The mean DLQI score decreased from 8.6 to 2.5 (-6.1) in the AV group and from 8.1 to 2.3 (-5.8) in the TA group. Between-group difference was 0.3 (95% confidence interval -1.18, -0.64, P = 0.5497). There was no follow-up period after the 8-week treatment. CONCLUSIONS AV cream may be more effective than 0.1% TA cream in reducing the clinical symptoms of psoriasis; however, both treatments have similar efficacy in improving the quality of life of patients with mild to moderate psoriasis.

Abstract
A non-blinded three armed study of the effect of Aloe vera, Essex and no lotion on erythema was performed. The erythema is an effect of radiotherapy treatment in breast cancer patients. The study required testing of objective methods for measuring the erythema. The chosen experimental methods were Near Infrared Spectroscopy, Laser Doppler Imaging and Digital Colour Photography. The experimental setup was made in such a way that in parallel with testing the effect of the lotions there was also a test of the sensitivity of the instruments. Fifty women were selected consecutively to participate in the study. They were all subjected to treatment with high-energy electrons (9-20 MeV) after mastectomy, 2 Gy/day to a total dose of 50 Gy. Measurements were performed before the start of radiotherapy and thereafter once a week during the course of treatment. Aloe vera and Essex lotion were applied twice every radiation day in selected sites. The increase in skin redness could be monitored with all techniques with a detection limit of 8 Gy for Digital Colour Photography and Near Infrared Spectroscopy and 18 Gy for Laser Doppler Imaging. In clinical practice our recommendation is to use Digital Colour Photography. No significant median differences were observed between the pairs no lotion-Essex, no lotion-Aloe vera and Essex-Aloe vera for any of the techniques tested.
