Abstract
Diabetes is a chronic condition that has an impact on a huge part of the world. Both animals and humans have been demonstrated to benefit from natural goods, and organisms (animals, or microbes). In 2021, approximately 537 million adults (20-79 years) are living with diabetes, making it the one of the biggest cause of death worldwide. Various phytoconstituent preserved β- cells activity helps to prevent the formation of diabetes problems. As a result, β-cells mass and function are key pharmaceutical targets. The purpose of this review is to provide an overview of flavonoids' effects on pancreatic β-cells. Flavonoids have been demonstrated to improve insulin release in cell lines of isolated pancreatic islets and diabetic animal models. Flavonoids are thought to protect β-cells by inhibiting nuclear factor-κB (NF-κB) signaling, activating the phosphatidylinositol 3-kinase (PI3K) pathway, inhibiting nitric oxide production, and lowering reactive oxygen species levels. Flavonoids boost β-cells secretory capacity by improving mitochondrial bioenergetic function and increasing insulin secretion pathways. Some of the bioactive phytoconstituents such as S-methyl cysteine sulfoxides stimulate insulin synthesis in the body and increase pancreatic output. The berberine increased insulin secretion in the HIT-T15 and Insulinoma 6 (MIN6) mouse cell line. Epigallocatechin-3-Gallate protects against toxicity accrued by cytokines, reactive oxygen species (ROS), and hyperglycemia. Quercetin has been proven to boost insulin production by Insulinoma 1 (INS-1) cells and also protect cell apoptosis. Overall flavonoids have beneficial effects on β-cells by prevented their malfunctioning or degradation and improving synthesis or release of insulin from β-cells.

[PMID: 37818339 PMCID: PMC10561288 DOI: 10.3389/fnut.2023.1126272] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 07/27/2023] [Indexed: 10/12/2023] Open
Abstract
Introduction Long used in traditional medicine, Nigella sativa (NS; Ranunculaceae) has shown significant efficacy as an adjuvant therapy for diabetes mellitus (DM) management by improving glucose tolerance, decreasing hepatic gluconeogenesis, normalizing blood sugar and lipid imbalance, and stimulating insulin secretion from pancreatic cells. In this review, the pharmacological and pharmacokinetic properties of NS as a herbal diabetes medication are examined in depth, demonstrating how it counteracts oxidative stress and the onset and progression of DM. Methods This literature review drew on databases such as Google Scholar and PubMed and various gray literature sources using search terms like the etiology of diabetes, conventional versus herbal therapy, subclinical pharmacology, pharmacokinetics, physiology, behavior, and clinical outcomes. Results The efficiency and safety of NS in diabetes, notably its thymoquinone (TQ) rich volatile oil, have drawn great attention from researchers in recent years; the specific therapeutic dose has eluded determination so far. TQ has anti-diabetic, anti-inflammatory, antioxidant, and immunomodulatory properties but has not proved druggable. DM's intimate link with oxidative stress, makes NS therapy relevant since it is a potent antioxidant that energizes the cell's endogenous arsenal of antioxidant enzymes. NS attenuates insulin resistance, enhances insulin signaling, suppresses cyclooxygenase-2, upregulates insulin-like growth factor-1, and prevents endothelial dysfunction in DM. Conclusion The interaction of NS with mainstream drugs, gut microbiota, and probiotics opens new possibilities for innovative therapies. Despite its strong potential to treat DM, NS and TQ must be examined in more inclusive clinical studies targeting underrepresented patient populations.

[PMID: 34808300 DOI: 10.1016/j.jep.2021.114856] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 11/09/2021] [Accepted: 11/17/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cyanotis tuberosa (Roxb.) Schult. &Schult.f. is traditionally used as ethnomedicine for curing several ailments like diabetes, liver problems, ulcers, etc. OBJECTIVE: The present study was designed to evaluate the anti-diabetic potential of Cyanotis tuberosa root tubers (CTRT)in Streptozotocin (STZ) induced diabetic rats. MATERIALS AND METHODS Anti-hyperglycemic activity of hexane extract of CTRT was investigated in diabetic rats. Silica gel chromatography was used to fractionate the hexane extract and the fraction's antihyperglycemic activity was checked in diabetic rats. Effects of long-term (30 days) treatment with an active fraction (CTAF) were evaluated in diabetic rats for 30 days by measurement of body weights, glycemic control, insulin levels, HbA1c, and serum and tissue lipid profiles. Lipid peroxide levels and antioxidant status were measured in the liver and kidney. Hepatic and Renal functional markers were also measured. Phytochemical characterization of CTAF was carried out by LC-ESI-MS/MS analysis. RESULTS Hexane extract of CTRT at a dose of 750 mg/kg b.w produced significant antihyperglycemic activity in diabetic rats whereas CTAF has produced maximum antihyperglycemic activity at the dose of 75 mg/kg b.w. Following long-term treatment with CTAF in diabetic rats, significant improvement in glycemic control, (HbA1c) along with decreased insulin resistance (HOMA-IR), increase in body weights, and plasma insulin were observed. Also, CTAF ameliorated the serum and tissue lipid profiles. In addition, CTAF suppressed lipid peroxidation and restored the activities of antioxidant enzymes in the liver and kidney to normal levels. Further, CTAF reversed the liver and kidney functional markers to normalcy. LC-ESI-MS/MS analysis revealed the presence of 7 different phytoconstituents. CONCLUSION This study confirmed that CTAF exerts antidiabetic effects in diabetic rats by improving insulin secretion, glycemic control, and restoring functional activities of the liver and kidney. Our results suggest that root tubers of Cyanotis tuberosa can be used as a complementary or alternative agent for the treatment of diabetes mellitus.

Abstract
Objective: Diabetes mellitus and dyslipidemia are currently increasing dramatically, and conventional medicine in the treatment of them has limited efficacies and serious adverse effects. Pluchea indica (L.) Less. tea (PIT) is widely consumed as a health-promoting drink in Southeast Asia. This study aimed to investigate whether P. indica tea has antidyslipidemic and antihyperglycemic effects and toxicity in humans. Design: A randomized clinical trial. Setting/Location: Nakhonratchasima, Thailand. Participants: Forty-five participants with prediabetes. Interventions: Participants were randomized to receive placebo tea, 1.5 g of PIT, and 1.5 g Camellia sinensis tea (green tea, CST) once daily for 12 weeks. Outcome Measurements: The oral glucose tolerance test (OGTT), total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), blood urea nitrogen (BUN), creatinine, alanine transaminase (ALT), alkaline phosphatase (ALP), and complete blood count (CBC) before and after treatment were investigated. Results: The results showed that PIT significantly ameliorated hyperglycemia and significantly lower serum TG (109.22 ± 5.21 mg/dL) and LDL-C (122.20 ± 3.67 mg/dL) than placebo (145.56 ± 8.18 and 142.07 ± 8.58 mg/dL, respectively) (p < 0.05). Moreover, PIT exhibited serum TG (109.22 ± 5.21 mg/dL) significantly lower than CST (124.38 ± 4.70 mg/dL) (p < 0.05). In addition, the serum HDL-C of PIT (57.56 ± 3.05 mg/dL) was significantly higher than the placebo (46.44 ± 2.47 mg/dL) (p < 0.05). Furthermore, the toxicity testing showed that no significant difference in BUN, creatinine, ALT, ALP, and CBC of PIT-treated group compared with the placebo (p > 0.05). Conclusions: These results suggest that PIT may ameliorate hyperglycemia and dyslipidemia in prediabetes people. It may not be toxic to the kidney, liver, and blood. So, PIT has the potential to develop to be a health-promoting tea or herbal medicine for hyperglycemia and dyslipidemia prevention.

Abstract
Oxidative stress is related to increased fat deposition in the liver, known as hepatic steatosis. The present study is an evaluation of the anti-oxidative and antihyperlipidemic effects of the hydroalcoholic extract of Rhus coriaria L. (HARE) in rats on a high-fat diet (HFD). Twenty male Wistar rats were divided into four groups: control, HFD, HFD + HARE 50 mg/kg/day, and HFD + HARE 250 mg/kg/day for 12 weeks. Animals were weighed weekly and treated with the HARE extract for 12 weeks by gavage. Subsequently, the histopathological changes, oxidative markers, and lipid profile were evaluated. Statistical analysis was performed using the one-way analysis of variance (ANOVA) for multiple comparisons. First, the active ingredients of the extract were determined by HPLC. Then, the levels in the serum lipid profile (TG, cholesterol, HDL, and LDL) in rats fed with the HFD + HARE were analyzed where a significant reduction was observed. The HFD proved to increase the activity of the liver enzymes, the serum lipid levels, and the malondialdehyde (MDA) level. The ferric-reducing antioxidant activity power (FRAP), catalase (CAT), and superoxide dismutase (SOD) catalytic activity were reduced in the liver homogenate of HFD rats compared to the controls. Additionally, the aforementioned liver enzymes activities were reduced in response to HARE. Evaluation of oxidative stress determined a reduction in the MDA level while a raised FRAP was confirmed. In accordance with the present results, histopathological observations have also demonstrated that HARE ameliorated grade-1 hepatic steatosis induced by HFD. Taken together, the findings of this study introduce HARE as a future potential therapeutic agent in treating hepatic steatosis and reducing oxidative damages of an HFD in the liver.

Abstract
AIMS Arganimide A (4,4-dihydroxy-3,3-imino-di-benzoic acid) is a compound belonging to a family of aminophenolics found in fruit of Argania spinosa. The purpose of this study was to investigate the glucose and lipid lowering activity of Arganimide A (ARG A). METHODS The effect of a single dose and daily oral administration of Arganimide A (ARG A) on blood glucose levels and plasma lipid profile was tested in normal and streptozotocin (STZ) diabetic rats at a dose of 2 mg/kg body weight. RESULTS Single oral administration of ARG A reduced blood glucose levels from 26.50±0.61 mmol/L to 14.27±0.73 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 5.35±0.30 mmol/L to 3.57±0.17 mmol/L (p<0.0001) and from 26.50±0.61 mmol/L to 3.67±0.29 mmol/L (p<0.0001) in normal and STZ diabetic rats, respectively, after seven days of treatment. Moreover, no significant changes in body weight in normal and STZ rats were shown. According to the lipid profile, the plasma triglycerides levels were decreased significantly in diabetic rats after seven days of ARG treatment (p<0.05). Moreover, seven days of ARG A treatment decreased significantly the plasma cholesterol concentrations (p<0.001). CONCLUSION ARG A possesses glucose and lipid-lowering activity in diabetic rats and this natural compound may be beneficial in the treatment of diabetes.

Abstract
Objective:
The aim of this randomized controlled trial was to investigate the effects of a
polyherbal compound consisting of Aloe vera, black seed, fenugreek, garlic, milk thistle, and psyllium
on diabetic patients with uncontrolled dyslipidemia.
Methods:
Fifty patients with type 2 diabetes who had dyslipidemia in spite of statin therapy were randomly
allocated to two groups: control group (n = 25) receiving a conventional therapy with hypolipidemic
and hypoglycemic drugs and intervention group (n = 25) receiving both the conventional therapy
and the herbal compound (one sachet twice daily) for 12 weeks. Each sachet contained 300 mg of
Aloe vera leaf gel, 1.8 g of black seed, 300 mg of garlic, 2.5 g of fenugreek seed, 1 g of psyllium seed,
and 500 mg of milk thistle seed.
Results:
The levels of serum triglyceride, total cholesterol, low-density lipoprotein, and HbA1c
showed a significant in-group improvement in the intervention group. However, the effects of the
herbal compound on fasting blood glucose remained insignificant. The compound had no unwanted
effect on the kidney function parameters (urea, creatinine) and serum liver enzymes (alanine
aminotransferase and aspartate transaminase).
Conclusion:
The tested herbal compound, as an add-on to statin therapy, was effective in lowering the
serum lipids in diabetic patients with uncontrolled dyslipidemia.

Abstract
Pancreatic β cells are a type of cells that are present in the islets of Langerhans. These cells are highly specialized for the secretion of insulin in response to low increasing of blood glucose levels. Hence, pancreatic β cells could contribute to maintaining systemic glucose homeostasis. Increasing evidence has revealed that a variety of internal (ie, genetic and epigenetic factors) and external factors (ie, radical-oxidative stress) are involved in the protection and/or regeneration of pancreatic β cells. The pathways regulating β-cell replication have been intensely investigated. Glucose has an important role in cell cycle entry of quiescent β cells, which exerts its effect via glucose metabolism and unfolded proteins. A variety of growth factors, hormones, and signaling pathways (ie, calcium-calcineurin nuclear factor of activated T cells) are others factors that could affect β-cell replication under different conditions. Therefore, a greater understanding of the underlying pathways involved in the regeneration and protection of pancreatic β cells could lead to finding and developing new therapeutic approaches. Utilization of stem cells and various phytochemical agents have provided new aspects for preventing β-cell degeneration and stimulating the endogenous regeneration of islets. Thus, these therapeutic platforms could be used as potential therapies in the treatment of insulin-dependent diabetes mellitus. Here, we summarized the various mechanisms involved in pancreatic β-cell regeneration. Moreover, we highlighted different therapeutic approaches which could be used for the regeneration of pancreatic β cells.

Abstract
Background:
Experimental studies have reported beneficial effects of Capparis spinosa L.,
a perennial shrub from the Capparidaceae family, on the glycemic status and serum lipids in diabetic
animals.
Objective:
The aim of the present randomized triple-blind placebo-controlled clinical trial was to investigate
the safety and efficacy of C. spinosa oxymel on blood glucose, lipid profile, and other diagnostic
indexes of metabolic syndrome in patients with poorly controlled type 2 diabetes.
Method:
The C. spinosa oxymel was prepared by adding hydroalcoholic extract of C. spinosa fruit to
simple oxymel (a mixture of grape vinegar and lactulose). Thirty diabetic patients with metabolic syndrome
whose glycemic status was not controlled despite receiving full doses of oral hypoglycemic
agents did not want to start insulin therapy and were randomly allocated to three groups to receive
placebo, simple oxymel, or C. spinosa oxymel (10 mL/thrice daily for 3 months). All patients continued
conventional therapy with hypolipidemic, antihyperlipidemic, and antihypertensive drugs during
the study.
Results:
C. spinosa oxymel significantly decreased the body weight and body mass index at the end of
the study compared to the baseline. While the patients in the placebo and simple oxymel groups displayed
further increase in the level of FBG or PPBG, administration of C. spinosa oxymel inhibited the
progression of hyperglycemia. Nevertheless, there was not a significant difference between placebo
and intervention groups regarding HbA1c at the end of the study. C. spinosa oxymel had no significant
effect on the serum cholesterol but inhibited the progression of hypertriglyceridemia during the study.
There were no significant changes in creatinine, microalbuminuria, AST, ALT, and ALP values following
C. spinosa treatment, suggesting that it had no unwanted effects on kidney and liver function.
Conclusion:
The results suggest that although C. spinosa oxymel cannot enhance the effects of hypoglycemic
and hypolipidemic drugs, it can prevent further increase of blood glucose and triglycerides in
patients with poorly controlled diabetes.

Abstract
Cardiovascular disease is a highly prevalent issue worldwide, and one of its main manifestations, dyslipidaemia, needs more attention. Cooked artichoke (Cynara scolymus) hearts or artichoke leaf extract (ALE) are believed to be helpful in the treatment of dyslipidaemia. In this narrative review, we provide a brief overview of the potential impact of artichoke consumption on lipid profile. We appraised the Cochrane, MEDLINE and Web of Science databases, and included articles published between 2000 and June 2018 on intervention in humans only. The main potential of ALE administration observed on lipid profile relates to decreased serum LDL, total cholesterol and triglyceride concentrations, although no strong evidence for increasing HDL appears to exist. Evidence suggests that decreases of 8-49 mg/dL for LDL concentration, 12-55 mg/dL for total cholesterol, and 11-51 mg/dL for triglycerides, can be attributed to 2 to 3 g/d of ALE, in which its components luteolin and chlorogenic acid may play a key role. On the other hand, the effects of cooked artichoke hearts can be attributed mainly to its soluble fibres, particularly inulin. Despite the convincing evidence on its health benefits, additional long-term clinical trials are pivotal to fully elucidate the potential effects of ALE administration on positive cardiovascular outcomes.

Abstract
An increasing line of evidence confirmed that apart from conventional hypoglycemic drugs, diet and medicinal plants have beneficial effects on diabetes. Capparis spinosa L. (Caper) is a perennial shrub in the Capparidaceae family. It grows in different regions of the world, particularly in Asian and African countries. A wide range of biological activities such as antioxidant, anti-inflammatory, anticancer, antimicrobial, and antidiabetic effects have been reported for this plant. In this review, it is focused on beneficial effects of C. spinosa on diabetes. Several studies have showed the antihyperglycemic and hypolipidemic activities of C. spinosa. The putative mechanisms involved in the antihyperglycemic effects of C. spinosa include reducing carbohydrate absorption from the small intestine, inhibiting gluconeogenesis in the liver, enhancing glucose uptake by tissues, and beta cell protection/regeneration. This plant also ameliorates cardiovascular disorders, liver damage, and nephropathy in animal models of diabetes, which are attributed to its antioxidant phytochemicals such as phenolic compounds, flavonoids, carotenoids, tocopherols, and terpenes. Antihyperglycemic and hypolipidemic activities of C. spinose, along with its beneficial effects on diabetic complications, make it a good candidate for the management of diabetes. Well-designed clinical trials are necessary to define the advantages and disadvantages of C. spinose for diabetic patients.

Abstract
Several lines of evidence suggest that flavonoids that originated from vegetables and medicinal plants have beneficial effects on diabetes by improving glycemic control, lipid profile, and antioxidant status. Rutin is a flavonoid found in many plants and shows a wide range of biological activities including anti-inflammatory, antioxidant, neuroprotective, nephroprotective, and hepatoprotective effects. In this review, the antihyperglycemic property of rutin and its protective effects against the development of diabetic complications are discussed. Proposed mechanisms for the antihyperglycemic effect of rutin include a decrease of carbohydrates absorption from the small intestine, inhibition of tissue gluconeogenesis, an increase of tissue glucose uptake, stimulation of insulin secretion from beta cells, and protecting Langerhans islet against degeneration. Rutin also decreases the formation of sorbitol, reactive oxygen species, advanced glycation end-product precursors, and inflammatory cytokines. These effects are considered to be responsible for the protective effect of rutin against hyperglycemia- and dyslipidemia-induced nephropathy, neuropathy, liver damage, and cardiovascular disorders. Taken together, the results of current experimental studies support the potential of rutin to prevent or treat pathologies associated with diabetes. Well-designed clinical studies are suggested to evaluate advantages and limits of rutin for managing diabetes.

Abstract
BACKGROUND In spite of promising experimental findings, randomized controlled trials (RCTs) have yielded mixed results on the impact of quercetin supplementation on plasma lipid levels. AIM The present study aimed to quantify the effects of quercetin on plasma lipids using a meta-analysis of RCTs. METHODS A systematic literature search of Medline was conducted for RCTs that investigated the efficacy of quercetin supplementation on plasma lipids comprising total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated for net changes in lipid concentrations using a random-effects model. Meta-regression analysis was conducted to assess the effect of quercetin dose and duration of supplementation as moderators on the calculated effect measures. RESULTS Five RCTs totaling 442 subjects (221 in the quercetin and 221 in the control group) fulfilled the eligibility criteria and selected for analyses. Combined estimate of effect size for the impact of quercetin on plasma LDL-C (WMD: 1.43 mg/dL, 95% CI: -0.92-3.78, p = 0.23), HDL-C (WMD: 0.26 mg/dL, 95% CI: -0.74-1.25, p = 0.61) and triglycerides (WMD: -9.42 mg/dL, 95% CI: -27.80-8.96, p = 0.32) was not statistically significant. However, a borderline significant but clinically non-relevant increase in total cholesterol was observed (WMD: 3.13 mg/dL, 95% CI: -0.01-6.27, p = 0.05). When the analysis was confined to the subgroups of studies with quercetin doses ≥500 mg/day and follow-up of ≥ 4 weeks, a significant increase in total cholesterol (WMD: 3.57 mg/dL, 95% CI: 0.21-6.92, p = 0.04) and a decline in triglycerides (WMD: -24.54 mg/dL, 95% CI: -33.09 to -15.99, p < 0.00001) was observed, but LDL-C and HDL-C concentrations remained unchanged (p > 0.05). Changes in plasma triglycerides, but not other indices of lipid profile, were significantly associated with quercetin dose (slope: -0.057; 95% CI: -0.103 to -0.010; p = 0.02) and duration of supplementation (slope: -5.314; 95% CI: -9.482 to -1.147; p = 0.01). CONCLUSION Available evidence from RCTs does not suggest any clinically relevant effect of quercetin supplementation on plasma lipids, apart from a significant reduction of triglycerides at doses above 50 mg/day.

Abstract
Numerus studies highlighted benefits of natural flavonoids in the management of diabetes. The present study was aimed to investigate the effects of a high flavonoids containing extract of Rheum turkestanicum on diabetic changes in different tissues. Male Wistar rats were divided into normal and streptozotocin-induced diabetic groups received saline or hydroalcoholic extract of R. turkestanicum root (100, 200 and 300mg/kg) through orogastric gavage for 4 weeks. Serum glucose, HbA1c, lipids, creatinine, uric acid, liver enzymes (alkaline phosphatase, aspartate aminotransferase and alanine aminotransferase), and cardiac enzymes (lactate dehydrogenase and creatine phosphokinase) in diabetic control group were significantly higher compared to normal control group (p<0.001). The extract significantly reduced these factors, increased body weight, and improved both glucosurea and proteinuria. Lipid peroxidation was high in the liver of diabetic rats compared to normal rats (p<0.001) and reverted toward control values by R. turkestanicum. Also, the extract significantly protected the liver, kidney, and heart of diabetic rats against histopathological changes. In conclusion, R. turkestanicum inhibited the development of nephropathy, liver injury, and myocardial damage in diabetes by lowering the serum levels of glucose and lipids, and by inhibiting oxidative stress mediated lipid peroxidation.

Abstract
Background: Several experimental and clinical studies support beneficial effects of Trigonella foenum-graecum (fenugreek) in the management of metabolic diseases and inflammatory disorders. Objectives: The purpose of this study was to examine the effect of T. foenum-graecum seed extract in reducing the metabolic and inflammatory alternations associated with menopause. Materials and Methods: In this experimental study, 49 rats were divided into seven groups: (I) sham-control, (II) ovariectomized-control, (III and IV) ovariectomized treated with 50 and 150 mg/kg of T. foenum-graecum seed ethanolic extract, (V and VI) ovariectomized treated with 50 and 150 mg/kg of T. foenum-graecum hexanic extract, (VII) ovariectomized-positive control treated with 10 µg/kg of estradiol. The extracts were injected intraperitoneally one day after ovariectomy and the treatments were lasted for 42 days. Results: Fasting blood glucose and body weight gain increased significantly in the ovariectomized-control group compared with that in the sham animals (P < 0.05). Administration of estradiol and T. foenum-graecum (50 and 150 mg/dL of hexanic extract and 150 mg/kg of ethanolic extract) significantly diminished the increase in glucose and body weight (P < 0.05). The serum level of interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in the ovariectomized control group was significantly higher than those in the sham animals (P < 0.05). Both hexanic and ethanolic extracts as well as estradiol were able to decrease level of these cytokines in the serum of ovariectomized rats (P < 0.05). Conclusions: The results of the present study show that administration of T. foenum-graecum corrects metabolic and inflammatory alterations associated with ovariectomy and has a potential for the management of menopause.

Abstract
The metabolic syndrome is a common problem world-wide and includes abdominal obesity, hypertension, dyslipidemia, and hyperglycemia disorders. It leads to insulin resistance and the development of diabetes mellitus or cardiovascular disease. Allium sativum (garlic) has been documented to exhibit anti-diabetic, hypotensive, and hypolipidemic properties. This suggests a potential role of A. sativum in the management of metabolic syndrome; however, more studies should be conducted to evaluate its effectiveness. In this review, we discussed the most relevant articles to find out the role of A. sativum in different components of metabolic syndrome and cardiovascular disease risk factors. Because human reports are rare, further studies are required to establish the clinical value of A. sativum in metabolic syndrome.

Abstract
Although currently available drugs are useful in controlling early onset complications of diabetes, serious late onset complications appear in a large number of patients. Considering the physiopathology of diabetes, preventing beta cell degeneration and stimulating the endogenous regeneration of islets will be essential approaches for the treatment of insulin-dependent diabetes mellitus. The current review focused on phytochemicals, the antidiabetic effect of which has been proved by pancreatic beta cell protection/regeneration. Among the hundreds of plants that have been investigated for diabetes, a small fraction has shown the regenerative property and was described in this paper. Processes of pancreatic beta cell degeneration and regeneration were described. Also, the proposed mechanisms for the protective/regenerative effects of such phytochemicals and their potential side effects were discussed.

Abstract
Diabetes mellitus is associated with dysregulation of adipose tissue metabolism and increased level of serum lipids. In our previous work we found that Securigera securidaca decreases cholesterol level in blood of diabetic rats. The present study was carried out to further investigate the effects of this plant on lipid metabolism, lipolysis, and adipogenesis, in diabetic rats. Female Wistar rats were rendered diabetic by intraperitoneal injection of streptozotocin. Retroperitoneal adipose tissue was removed from diabetic animals after seven days of streptozotocin injection. Effect of hydroalcoholic extract of S. securidaca seeds (100-800 μg/mL) on adipose tissue lipolysis was evaluated in ex vivo condition. Also, to evaluate adipogenesis, preadipocytes were isolated from adipose tissue and differentiated to adipocytes in the presence of the extract. The extract at concentration of 800 μg/mL decreased both basal and catecholamine-stimulated lipolysis (P < 0.05). Incubation of differentiating preadipocytes with 800 μg/mL of S. securidaca extract decreased intracellular lipid droplet accumulation as evaluated with Oil Red O staining (P < 0.001). The extract even at high concentrations had no effect on viability of preadipocytes. In conclusion, S. securidaca decreases lipolysis and adipogenesis without cytotoxicity, which makes it a good candidate for management of dyslipidemia and reduction of cardiovascular risks in diabetes.

Abstract
The effects of a polyherbal mixture containing Allium sativum, Cinnamomum zeylanicum, Citrullus colocynthis, Juglans regia, Nigella sativa, Olea europaea, Punica granatum, Salvia officinalis, Teucrium polium, Trigonella foenum, Urtica dioica, and Vaccinium arctostaphylos were tested on biochemical parameters in diabetic rats. The animals were randomized into three groups: (1) normal control, (2) diabetic control, and (3) diabetic rats which received diet containing 15% (w/w) of this mixture for 4 weeks. Diabetes was induced by intraperitoneal injection of streptozotocin (55 mg/kg). At the end of experiment, the mixture had no significant effect on serum hepatic enzymes, aspartate aminotransferase, and alanine aminotransferase activities. However, the level of fasting blood glucose, water intake, and urine output in treated group was lower than that in diabetic control rats (P < 0.01). Also, the levels of triglyceride and total cholesterol in polyherbal mixture treated rats were significantly lower than those in diabetic control group (P < 0.05). Our results demonstrated that this polyherbal mixture has beneficial effects on blood glucose and lipid profile and it has the potential to be used as a dietary supplement for the management of diabetes.
