BACKGROUND: Obesity prevalence has increased during the past few decades, causing a pandemic with an influx in other co-morbidities. Many factors influence weight gain in an obesogenic environment therefore strategies for treating obesity may vary from conventional dietary and physical activity interventions to pharamacotherapy. A shift in unconventional strategies as herbal products for treating obesity have been investigated and one such plant extract is Caralluma fimbriata (C. fimbriata). Further, the studies included were systematically reviewed to gather evidence on potential effects of C. fimbriata as an appetite suppressant and weight loss supplement. METHODS: A systematic review of clinical trials reporting the effects of C. fimbriata as appetite suppression and anti-obesity supplement was reported according to PRISMA guidelines. Data were obtained by searching three databases: PubMed®, Web of Science® and SciVerse Scopus® for studies published until 30th April 2020. RESULTS: A total of 7 articles studying C. fimbriata satisfied the inclusion and exclusion criteria and were sourced from various countries including Australia (3), Cuba (1), India (2) and Spain (1). Almost all studies recruited adults who were overweight or obese with a BMI > 25 kg/m2 (n = 5), with the exception of two studies, one that recruited healthy adults with a BMI average of 26.5 kg/m2 and the second one utilised a population of children and adolescents with Prader-Willis Syndrome (PWS). Parameters assessing obesity, biochemical and appetite factors were analysed by carrying out a meta-analysis. Compared to placebo controlled group, C. fimbriata extract significantly reduced WC by 1.59 cm (95% CI, - 3.07 to - 0.10, p = 0.041) and WHR by 0.06 (95% CI, - 0.12 to - 0.01, p = 0.05) although no significant effects were seen on BW, BMI and HC. Biochemical and appetite parameters outcome on C. fimbriata consumption had no significant changes. Any side effects of individuals who ingested the extract were reported by few studies of which most common effects were constipation, diarrhoea, nausea and rashes. CONCLUSION: Appetite parameters showed no significant changes and metabolic parameters

INTRODUCTION: The hypothalamic-pituitary-adrenal (HPA) axis plays a central role in the stress response. Plants, herbs, spices, and plant-based nutrients may influence HPA-axis activity. OBJECTIVE: To evaluate randomised controlled, human trials assessing the effects of single plants or phytonutrients on HPA-axis related hormones. METHODS: A systematic review of PubMed, Cochrane library, and the Cumulative Index to Nursing and Allied Health Literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Inclusion criteria comprised of human, randomised controlled studies with a control intervention examining the effects of a single herb, spice, plant, or extract on pre- and post-changes in blood, saliva, urine, or hair concentrations of cortisol, cortisone, corticotrophin-releasing hormone, or adrenocorticotropic hormone. Databases were searched from inception until October 2020. RESULTS: Fifty-two studies were identified examining the effects of ashwagandha, Korean ginseng, St John's Wort, cannabidiol, Rhodiola rosea, curcumin, cherry juice, asparagus, Jiaogulan, Black cohosh, Siberian ginseng, Bacopa monnieri, blueberries, green tea, Caralluma fimbriata, cashew apple juice, melon, American ginseng, Ginkgo biloba, grape juice, grapefruit juice, rosella, hops, mangosteen, holy basil, and pomegranate juice. Due to significant variability in study designs, the effect of phytonutrients on HPA-axis activity in humans was unclear. The most consistent finding was a morning, cortisol-lowering effect from ashwagandha supplementation. CONCLUSION: For most phytonutrients, the effects of supplementation on HPA-axis activity in humans is unclear. Before more definitive conclusions about the effects of phytonutrients on the HPA-axis can be made, further research is required.

Obesity is a medical situation in which excess body fat has gathered because of imbalance between energy intake and energy expenditure. In spite of the fact that the variety of studies are available for obesity treatment and management, its "globesity" still remains a big challenge all over the world. The current systematic review and meta-analysis aimed to evaluate the efficacy, safety, and mechanisms of effective herbal medicines in the management and treatment of obesity and metabolic syndrome in human. We systematically searched all relevant clinical trials via Web of Science, Scopus, PubMed, and the Cochrane database to assess the effects of raw or refined products derived from plants or parts of plants on obesity and metabolic syndrome in overweight and obesity adult subjects. All studies conducted by the end of May 2019 were considered in the systematic review. Data were extracted independently by two experts. The quality assessment was assessed using Consolidated Standards of Reporting Trials checklist. The main outcomes were anthropometric indices and metabolic syndrome components. Pooled effect of herbal medicines on obesity and metabolic syndrome were presented as standardized mean difference (SMD) and 95% confidence interval (CI). A total of 279 relevant clinical trials were included. Herbals containing green tea, Phaseolus vulgaris, Garcinia cambogia, Nigella sativa, puerh tea, Irvingia gabonensis, and Caralluma fimbriata and their active ingredients were found to be effective in the management of obesity and metabolic syndrome. In addition, C. fimbriata, flaxseed, spinach, and fenugreek were able to reduce appetite. Meta-analysis showed that intake of green tea resulted in a significant improvement in weight ([SMD]: -0.75 [-1.18, -0.319]), body mass index ([SMD]: -1.2 [-1.82, -0.57]), waist circumference ([SMD]: -1.71 [-2.66, -0.77]), hip circumference ([SMD]: -0.42 [-1.02, -0.19]), and total cholesterol, ([SMD]: -0.43 [-0.77, -0.09]). In addition, the intake of P. vulgaris and N. sativa resulted in a significant improvement in weight ([SMD]: -0.88, 95 % CI: [-1.13, -0.63]) and triglyceride ([SMD]: -1.67, 95 % CI: [-2.54, -0.79]), respectively.

OVERVIEW: As obesity has reached epidemic proportions, the management of this global disease is of clinical importance. The availability and popularity of natural dietary supplements for the treatment of obesity has risen dramatically in recent years. AIMS: The aim of this paper was to assess the current evidence of commonly available natural supplements used to suppress appetite for obesity control and management in humans using a systematic search of clinical trials meeting an acceptable standard of evidence. METHODS: The electronic databases PubMed, Web of Science, Google Scholar, ScienceDirect, and MEDLINE with full text (via EBSCOHost) were accessed during late 2012 for randomized controlled clinical trials (RCTs) using natural plant extracts as interventions to treat obesity through appetite regulation. A quality analysis using a purpose-designed scale and an estimation of effect size, where data were available, was also calculated. The inclusion criteria included the following: sample participants classified as overweight or obese adults (aged 18-65 years), randomized, double blind, controlled design, suitable placebo/control intervention, sample size >20, duration of intervention >2 weeks, have measurable outcomes on appetite or food intake and anthropometry, and full paper in English. RESULTS: There were 14 studies that met the inclusion criteria. The findings from published double blind RCTs revealed mostly inconclusive evidence that plant extracts are effective in reducing body weight through appetite suppression. Caralluma fimbriata extract and a combination supplement containing Garcinia cambogia plus Gymnema sylvestre were the only exceptions. CONCLUSION: According to the findings from this systematic review, the evidence is not convincing in demonstrating that most dietary supplements used as appetite suppressants for weight loss in the treatment of obesity are effective and safe. A balance between conclusive findings by double blind RCTs and advertisement is required to avoid safety concerns and dissatisfaction from consumers.

BACKGROUND: This study investigated the efficacy of a succulent, Caralluma fimbriata extract (CFE) in reducing anxiety and stress in healthy adults. METHODS: An 8 week double-blind randomised clinical trial, in which 97 adults self-reporting mild to moderate anxiety were given 500 mg b.d. CFE (n = 49), or 500 mg b.d. placebo (n = 48). Anxiety and stress were measured at baseline, week 4, and week 8 to investigate the timing of treatment effect using the GAD-7, Perceived Stress Scale (PSS), Positive and Negative Affect Schedule (PANAS), and salivary cortisol. Data were analysed using mixed ANOVAs on SPSS v.24. RESULTS: Results indicated a significant reduction in anxiety and stress in both groups at week 4 and week 8. The reduction in the CFE group was significantly greater (p < .05) than in the placebo group on the GAD-7 and PSS at week 4 and week 8, and in Negative affect at week 4. Improvement in Positive affect was greater in the CFE group than in the placebo group at week 8. Cortisol analysis indicated that CFE may act through the Hypothalamic-Pituitary-Adrenal (HPA) axis, showing statistically significant changes in males, but not in females. LIMITATIONS: Self-reported instruments involve subjective interpretation thus salivary cortisol was employed as a more objective measure. The study would benefit from a larger sample and longer trial, and the inclusion of a wait-list group to allow comparison between treatment and no treatment. CONCLUSIONS: The findings indicate that CFE is superior to placebo in reducing subclinical anxiety and stress over 8 weeks.

BACKGROUND: Prader-Willi syndrome (PWS) results from a deletion of the paternal genes in the region of chromosome 15q11-q13. PWS develops hyperphagia, which when left unmanaged, leads to an excessive ingestion of food. To date there is inadequate pharmacological treatment or supplementation for modification of the PWS hyperphagia and/or the associated behaviors. Therefore, the best practice is familial supervision and restriction of diet and environment. AIM: We aimed to determine if the natural supplement of Caralluma fimbriata extract (CFE) could attenuate hyperphagia or the associated appetite behaviors in children and adolescents with PWS over the 4-week pilot trial period. MATERIALS AND METHODS: We conducted a placebo-controlled, double-blind, randomized crossover trial over a 10-week period to investigate the effects of CFE on hunger control, in a cohort of children and adolescents with confirmed PWS (n =15, mean age 9.27 ± 3.16 years, body weight 43.98 ± 23.99 kg). Participants from Australia and New Zealand ingested CFE or a placebo of maltodextrin/cabbage leaf over a 4-week period, with a 2-week washout before the crossover to the other treatment. Weekly comparisons in appetite behavior, severity, and drive were recorded by parents, as scaled time-point measures on a hyperphagia questionnaire validated for PWS. RESULTS: CFE administration was found to induce a significant accumulative easing of hyperphagia (P = 0.05), with decreases evident in one-third of the participants. Furthermore due to CFE supplementation, a significant decrease (P ≤ 0.05) was recorded in the category of behavior and a decrease in hyperphagia (n = 8, P = 0.009) was observed at the highest dose 1,000 mg/day (recommended adult dose). There were no reported adverse effects at any dose. CONCLUSION: We demonstrate that an extract of the Indian cactus succulent Caralluma fimbriata eases hyperphagic appetite behavior within a cohort of children and adolescents (n = 15) with PWS without notable adverse effects. The outcomes of this study will have a potential positive impact on PWS management.

To examine the effect of a Caralluma Fimbriata extract (CFE) on biomarkers of satiety and body composition in overweight adults. A double-blind, randomised, placebo controlled trial to examine the effect of a Caralluma Fimbriata extract (CFE) on biomarkers of satiety and body composition in overweight adults. Eighty-three men and women aged between 20 and 50 years of age completed 16 weeks of daily supplementation with either CFE or placebo. Plasma cardiometabolic (lipid profile, glucose, insulin) and satiety (ghrelin, leptin, neuropeptideY) biomarkers, body composition, diet history and gastrointenstinal function were assessed at baseline, weeks 4, 8, 12 and 16. Subjects in the CFE and placebo groups were well matched and predominatly female 93% and 87.5%, with a mean age of 40.9 ± 6.7 and 39.5 ± 7.5 years and body mass index (BMI) of 30.0 ± 3.1 and 30.2 ± 2.9 kg/m2 respectively. There was a significant difference in plasma leptin concentration change between groups at week 16 (p = 0.04), with the placebo group increasing concentration (2.27 ± 4.80 ng/mL) while the CFE group (0.05 ± 4.69 ng/mL) remained the same. At week 16, the CFE group had significantly reduced their calorie intake from baseline compared to the placebo group (245 cal vs 15.8 cal respectively p < 0.01). The CFE group also had a significant reduction in waist circumference of 2.7 cm compared to an increase of 0.3 cm in the placebo group (p = 0.02). A weight increase from baseline was seen in the placebo group that was not observed in the CFE group (1.33 kg weight gain vs 0.37 kg weight loss respectively; p = 0.03). The placebo group also had a significant increase in fat mass, android fat mass, BMI and leptin compared to the CFE group (p = 0.04, 0.02, < 0.01 respectively). CFE was effective at maintaining bodyweight during a non-calorie controlled diet compared to a placebo. The mechanism responsible for this action is requiring further research and could be due to an increase in satiety receptor sensitivity.

OBJECTIVES: Central obesity is a key component of metabolic syndrome and it is often associated with other risk factors such as dyslipidemia, elevated plasma glucose levels and elevated blood pressure (BP). In this pilot study, the effect of Caralluma fimbriata (an edible succulent) extract in combination with controlled dietary intake and physical activity on these risk factors was assessed in overweight and obese Australian subjects. DESIGN: This was a randomised, double blind placebo controlled clinical trial. Forty-three adults aged 29-59 years were recruited. The eligibility criteria included a Body Mass Index (BMI) >25 kg/m(2), or a waist circumference >94 cm (male), >80 cm (female). Thirty-three participants completed the 12-week study at Victoria University Nutritional Therapy Clinic. Participants were randomly assigned into two groups. C. fimbriata extract and placebo were orally administered as 500 mg capsules twice daily (1 g/day) and dietary intake and exercise were monitored weekly. RESULTS: The results of thirty-three participants (experimental group, n = 17; placebo group n = 16) were analysed. The primary outcome measure was the decline in waist circumference. By week 9, the experimental group had lost 5.7 cm, compared to only 2.8 cm loss in the placebo group (Difference: -2.890; 95% CI; -5.802 to 0.023). Post intervention, the experimental group had lost 6.5 cm compared to 2.6 cm loss in the placebo group (Difference: -3.847; 95% CI; -7.466 to 0.228). Waist to hip ratio (WHR) also improved significantly after 12 weeks intervention in the experimental group, with a total reduction of 0.03 being recorded compared to 0.01 increase in the placebo group (Difference: -0.033; 95% CI; -0.064 to -0.002). There was also a significant decline in the palatability (visual appeal, smell, taste) of the test meal and sodium intake in the experimental group at week 12 (p < 0.05). In addition a significant reduction in body weight, BMI, hip circumference, systolic BP, HR, triglyceride levels, total fat and saturated fat intake within both groups was observed following the intervention period (p < 0.05). CONCLUSION: Supplementation with C. fimbriata extract whilst

Caralluma fimbriata is an edible cactus, used by tribal Indians to suppress hunger and enhance endurance. The effect of Caralluma extract was assessed in overweight individuals by a placebo controlled randomized trial. Fifty adult men and women (25-60 years) with a body mass index (BMI) greater than 25 kg/m2 were randomly assigned into a placebo or experimental group; the latter received 1 g of Caralluma extract per day for 60 days. All subjects were given standard advice regarding a weight reducing diet and physical activity. At the end of 30 and 60 days of intervention, blood glucose and lipids, anthropometric measurements, dietary intake and assessment of appetite was performed. Waist circumference and hunger levels over the observation period showed a significant decline in the experimental group when compared to the placebo group. While there was a trend towards a greater decrease in body weight, body mass index, hip circumference, body fat and energy intake between assessment time points in the experimental group, these were not significantly different between experimental and placebo groups. Caralluma extract appears to suppress appetite, and reduce waist circumference when compared to placebo over a 2 month period.
