Zhang Q, Bai Y, Wang W, Li J, Zhang L, Tang Y, Yue S. Role of herbal medicine and gut microbiota in the prevention and treatment of obesity. JOURNAL OF ETHNOPHARMACOLOGY 2023; 305:116127. [PMID: 36603782 DOI: 10.1016/j.jep.2022.116127] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 12/16/2022] [Accepted: 12/30/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Obesity is a common metabolic dysfunction disease, which is highly correlated with the homeostasis of gut microbiota (GM). The dysregulation of GM on energy metabolism, immune response, insulin resistance and endogenous metabolites (e.g., short chain fatty acids and secondary bile acids) can affect the occurrence and development of obesity. Herbal medicine (HM) has particular advantages and definite therapeutic effects in the prevention and treatment of obesity, but its underlying mechanism is not fully clear. AIM OF THE STUDY In this review, the representative basic and clinical anti-obesity studies associated with the homeostasis of GM regulated by HM including active components, single herb and herbal formulae were summarized and discussed. We aim to provide a state of art reference for the mechanism research of HM in treating obesity and the further development of new anti-obesity drugs. MATERIALS AND METHODS The relevant information was collected by searching keywords (obesity, herbal medicine, prescriptions, mechanism, GM, short chain fatty acids, etc.) from scientific databases (CNKI, PubMed, SpringerLink, Web of Science, SciFinder, etc.). RESULTS GM dysbiosis did occur in obese patients and mice, whiles the intervention of GM could ameliorate the condition of obesity. HM (e.g., berberine, Ephedra sinica, Rehjnannia glutinosa, and Buzhong Yiqi prescription) has been proved to possess a certain regulation on GM and an explicit effect on obesity, but the exact mechanism of HM in improving obesity by regulating GM remains superficial. CONCLUSION GM is involved in HM against obesity, and GM can be a novel therapeutic target for treating obesity.

Metabolomics analysis reveals amelioration effects of yellowhorn tea extract on hyperlipidemia, inflammation, and oxidative stress in high-fat diet-fed mice. Front Nutr 2023; 10:1087256. [PMID: 36742424 PMCID: PMC9894254 DOI: 10.3389/fnut.2023.1087256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 01/03/2023] [Indexed: 01/20/2023] Open
Abstract
Yellowhorn tea (YT) is traditionally used as a lipid-lowering beverage in Mongolian minorities. However, the pharmacological effects of YT extract and its specific metabolic changes in hyperlipidemia models are not fully understood. The aim of this study was to identify biomarkers using untargeted metabolomics techniques and to investigate the mechanisms underlying the changes in metabolic pathways associated with lipid lowering, anti-inflammation and anti-oxidant in hyperlipidemic mice. A high-fat diet (HFD)-induced hyperlipidemic mouse model was established. YT extract was administered as oral gavage at 0.15, 0.3, and 0.6 g/kg doses for 10 weeks. HFD-induced hyperlipidemia and the therapeutic effect of YT extract were evaluated based on histopathology and by assessing blood lipid levels. Liver inflammatory factors and oxidative stress indices were determined using enzyme-linked immunosorbent assays. Liver metabolites were evaluated using untargeted metabolomics. Biochemical and histological examinations showed that YT extract significantly reduced body-weight gain (p < 0.01) and fat deposition in tissues. YT extract significantly reduced the levels of serum and liver triglyceride and total cholesterol; inflammatory factors [interleukin (IL)-6, IL-1β, and tumor necrosis factor-α]; malondialdehyde; and leptin (p < 0.05) in hyperlipidemic mice. YT extract also significantly increased the levels of oxidative stress indicators (superoxide dismutase, catalase, and glutathione peroxidase) and adiponectin. Metabolomics studies revealed several endogenous molecules were altered by the high-fat diet and recovery following intervention with YT extract. The metabolites that were significantly different in the liver after YT intake included citicoline, acetylcholine, pyridoxine, and NAD. Pathway analysis indicated that YT extract ameliorated HFD-induced hyperlipidemia in mice via three major metabolic pathways, namely, glycerophospholipid metabolism, vitamin B6 metabolism, and nicotinate and nicotinamide metabolism. This study demonstrates YT extract has profound effects on the alleviation of HFD-induced hyperlipidemia, inflammation and oxidative stress.

Abstract
OBJECTIVES Crataegus pinnatifida (C. pinnatifida), including C. pinnatifida Bge. and its variant C. pinnatifida Bge. var. major N, E. Br., has traditionally been used as a homologous plant for traditional medicine and food in ethnic medical systems in China. Crataegus pinnatifida, especially its fruit, has been used for more than 2000 years to treat indigestion, stagnation of meat, hyperlipidemia, blood stasis, heart tingling, sores, etc. This review aimed to provide a systematic summary on the botany, traditional uses, phytochemistry, pharmacology and clinical applications of C. pinnatifida. KEY FINDINGS This plant contains flavonoids, phenylpropanoids, terpenoids, organic acids, saccharides and essential oils. Experimental studies showed that it has hypolipidemic, antimyocardial, anti-ischemia, antithrombotic, anti-atherosclerotic, anti-inflammatory, antineoplastic neuroprotective activity, etc. Importantly, it has good effects in treating diseases of the digestive system and cardiovascular and cerebrovascular systems. SUMMARY There is convincing evidence from both in vitro and in vivo studies supporting the traditional uses of C. pinnatifida. However, multitarget network pharmacology and molecular docking technology should be used to study the interaction between the active ingredients and targets of C. pinnatifida. Furthermore, exploring the synergy of C. pinnatifida with other Chinese medicines to provide new understanding of complex diseases may be a promising strategy.

[PMID: 35702955 DOI: 10.1111/jfbc.14270] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 04/10/2022] [Accepted: 05/17/2022] [Indexed: 11/29/2022]
Abstract
The effective components of mulberry leaf polyphenols (MLPs) should be absorbed and transported by the intestinal cells before regulating lipid metabolism. The Caco-2 intestinal epithelial cell and 3 T3-L1 adipocytes were coupled to screen the effective components of MLPs that are being absorbed and transported by intestinal cells. The regulation and molecular mechanism by which the effective components affect adipogenesis were analyzed in this study. Among the 12 main components identified, five main compounds were well absorbed with Papp in the order of benzoic acid > chlorogenic acid > astragaloside > hyperoside > rutin. Chlorogenic acid and benzoic acid were mainly absorbed through passive diffusion, while rutin, astragaloside, and hyperoside were mainly by active transport, of which chlorogenic and rutin absorption were mediated by the efflux protein, P-glycoprotein (P-pg). Based on the transport volume of 2 mg/ml MLPs within 2 h, 25% of the maximum transported MLPs (TMLPs) was a safe concentration for 3 T3-L1 preadipocytes. Except for astragaloside, the other four components showed a significant inhibitory effect on lipid droplets, TG and TC, and chlorogenic acid and benzoic acid had the strongest effect. Additionally, we observed a synergistic effect as TMLPs were the most effective. We hypothesized that TMLPs, chlorogenic acid and benzoic acid suppressed adipogenesis and regulated lipid metabolism by inhibiting PPAR-γ, C/EBP-α, and FAS mRNA while promoting ADIPO and Leptin mRNA expression. PRACTICAL APPLICATIONS: The absorption and adipogenesis inhibition effect of mulberry leaf phenolics were evaluated in this study. The results provided guideline for the development of functional foods in regulating lipid metabolism.

Abstract
Chemical investigations of the 75% EtOH extract from the fruits of Crataegus pinnatifida led to the isolation of three undescribed naturally occurring sesquineolignans with two 8-O-4'-type neolignan moieties, cratapinnatifidas A-C (1-3). Their chemical structures were elucidated by the comprehensive spectroscopic analyses (HRESIMS, 1D and 2D-NMR). In the bioactivity assay, their cytotoxic activities against two human hepatoma cell lines (HepG2 and Hep3B) were evaluated and no significant activity was seen with IC50 values ranging from 12.5 to 50.0 μM.

Abstract
The gastroprotective effect of a turmeric acetone extract (TAE) (Curcuma longa L. [Zingiberaceae]) was evaluated and compared against its major curcuminoids; curcumin (CUR), demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC). Additionally, to demonstrate the importance of the metabolites' ratio in the extract on the synergistic effect, different mixtures were evaluated. An ethanol-induced gastric injury model was used to evaluate the gastroprotection activity in Wistar rats. The pharmacologic interaction analysis was performed using the Combination Index (CI)-Isobologram Equation method. The CI calculated at 0.5 of affected fraction (fa) for the TAE indicated a synergistic interaction between its components. However, when the proportion of curcuminoids changed from 3.7:1:10 in TAE to a 1:1:1 ratio, the CI implied an antagonistic effect. The binary combinations of curcuminoids (1:1) also showed an antagonistic interaction. The results of this work suggest that the proportion of curcuminoids in the TAE is crucial for the gastroprotective effect against ethanol-induced damage.

Front Pharmacol 2020; 11:528. [PMID: 32435189 PMCID: PMC7218108 DOI: 10.3389/fphar.2020.00528] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Accepted: 04/03/2020] [Indexed: 12/12/2022] Open
Abstract
Objective Investigate the active ingredients and underlying hypolipidemic mechanisms of Danhe granule (DHG). Methods The lipid-lowering effect of DHG was evaluated in hyperlipidemic hamsters induced by a high-fat diet. The ingredients absorbed into the blood after oral administration of DHG in hamsters were identified by ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF/MS). A systems pharmacology approach incorporating target prediction and network construction, gene ontology (GO) enrichment and pathway analysis was performed to predict the active compounds and map the compounds-targets-disease network. Real-time polymerase chain reaction (RT-PCR) and Western blot were utilized to analyze the mRNA and protein expression levels of predicted targets. Results DHG remarkably lowered the levels of serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-c), and arteriosclerosis index (AI), at the same time, elevated the levels of serum high-density lipoprotein cholesterol (HDL-c) and HDL-c/TC ratio in hyperlipidemic hamsters. Sixteen ingredients absorbed into blood after oral administration of DHG were identified as the possible components interacted with targets. Moreover, 65 potential targets were predicted after targets intersection and compounds–targets–disease network mapping. Then, compounds–targets–pathways network mapping revealed that six active compounds (emodin, naringenin, etc.) compounds could interact with 10 targets such as sterol regulatory element binding protein (SREBP) 1c, SREBP-2 and peroxisome proliferation-activated receptor (PPAR) α, regulate three lipid metabolism-related pathways including SREBP control of lipid synthesis pathway, PPAR signaling pathway and nuclear receptors in lipid metabolism and toxicity pathway, and further affect lipid metabolic processes including fatty acid biosynthesis, low-density lipoprotein receptor (LDLR)-mediated cholesterol uptake, bile acid biosynthesis, and cholesterol efflux. Experimental results indicated that DHG significantly increased SREBP-2, LDLR, PPARα, liver X receptor alpha (LXRα), cholesterol 7α-hydroxylase (CYP7A1), and ATP binding cassette subfamily A member 1 (ABCA1) mRNA and protein expressions while decreased SREBP-1c and fatty acid synthase (FAS) mRNA, and protein expressions. Conclusion DHG possessed a good hypolipidemic effect that may be through affecting the mRNA and protein expressions of SREBP-1c, FAS, SREBP-2, LDLR, PPARα, LXRα, CYP7A1, and ABCA1, involving in fatty acid synthesis, LDLR-mediated cholesterol uptake, bile acid biosynthesis, and cholesterol efflux. This study further provided experimental evidence about its practical application for treating hyperlipidemia and its complications.

Abstract
Medicine-food homology is a long-standing concept in traditional Chinese medicine. YiNianKangBao (YNKB) tea is a medicine-food formulation based on Sichuan dark tea (Ya'an Tibetan tea), which is traditionally used for its lipid-lowering properties. In this study, we evaluated the effects of YNKB on dyslipidemia and investigated the mechanism underlying its correlation with gut microbiota and serum metabolite regulation. Wild-type mice were fed a normal diet as a control. Male ApoE-/- mice were randomly divided into three high-fat diet (HFD) groups, a model group, and two treated groups (100, 400 mg/kg/d for low, high-dose), and fed by gavage for 12 weeks. Serum lipid levels, composition of gut microbiota, and serum metabolites were then analyzed before treatment with YNKB. We extracted the ingredients of YNKB in boiled water for one hour. YNKB supplementation at a high dose of 400 mg/kg/day reduced bodyweight gains (relative epididymal fat pad and liver weight), and markedly attenuated serum lipid profiles and atherosclerosis index, with no significant differences present between the low-dose treatment and HFD groups. Gut microbiota and serum metabolic analysis indicated that significant differences were observed between normal, HFD, and YNKB treatment groups. These differences in gut microbiota exhibited strong correlations with dyslipidemia-related indexes and serum metabolite levels. Oral administration of high-dose YNKB also showed significant lipid-lowering activity against hyperlipidemia in apoE-deficient mice, which might be associated with composition alterations of the gut microbiota and changes in serum metabolite abundances. These findings highlight that YNKB as a medicine-food formulation derived from Sichuan dark tea could prevent dyslipidemia and improve the understanding of its mechanisms and the pharmacological rationale for preventive use.

Abstract
Hawthorn is a widely used herbal alternative medicine for the treatment of various cardiovascular diseases. However, the attributed health benefits, purported to be due to the presence of phenolic compounds, may depend on both the specific species and plant part. Studies to date investigating effects of hawthorn on heart disease(s) have used well-described European and/or Asian species, while little is known regarding the bioactivity of species native to North America. Six weeks of supplementation of both fireberry hawthorn berry (native Crataegus chrysocarpa) and English hawthorn leaf (C. monogyna, naturalized in North America) in the JCR:LA-cp rat, resulted in a significant reduction in heart weight, fasting LDL-C and improved heart function (p < 0.05). Fasting triglyceride and myocardial fibrosis were also reduced, but only by the berry extract. We demonstrate that both of the Canadian-sourced hawthorn extracts (introduced leaf and native berry) have cardioprotective benefits, likely via increased availability of nitric oxide.

Abstract
The aim of this study was to investigate and compare the effects of three herbal mixture extracts on obesity induced by high-fat diet (HFD) in rats. The prescriptions—Pericarpium citri reticulatae and Fructus crataegi—were used as matrix components and mixed with Ampelopsis grossedentata, Salvia miltiorrhiza, and epigallocatechin-3-gallate (EGCG) to form T1, T2, and T3 complexes, respectively. Results revealed that HFD feeding significantly increased body weight gain, fat deposition, plasma lipid profiles, hepatic lipid accumulation, and hepatic vacuoles formation, but decreased plasma levels of adiponectin in rats. Only the T1 complex showed the tendency, although not significantly so, for decreased HFD-induced body weight gain. T1 and T3 complexes significantly reduced HFD-induced fat deposition, and plasma levels of triglyceride, total cholesterol, and low-density lipoprotein cholesterol. Only the T1 complex significantly increased HFD-reduced adiponectin levels in plasma, but decreased HFD-increased triglyceride content in liver tissues. All complexes effectively inhibited HFD-induced vacuoles formation. The content of dihydromyricetin, salvianolic acid B, and EGCG in T1, T2, and T3 complexes was 18.25 ± 0.07%, 22.20 ± 0.10%, and 18.86 ± 0.04%, respectively. In summary, we demonstrated that herbal mixture extracts, especially T1 complex, exhibit antiobesity activity in HFD-fed rats.

Chu SM, Shih WT, Yang YH, Chen PC, Chu YH. Use of traditional Chinese medicine in patients with hyperlipidemia: A population-based study in Taiwan. JOURNAL OF ETHNOPHARMACOLOGY 2015; 168:129-135. [PMID: 25828254 DOI: 10.1016/j.jep.2015.03.047] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2014] [Revised: 03/18/2015] [Accepted: 03/19/2015] [Indexed: 06/04/2023]
Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE Chinese herbal products (CHPs) are commonly used in patients with hyperlipidemia in traditional Chinese medicine (TCM). Because hyperlipidemia and related disease are common issues worldwide, this study analyzed the prescription patterns and frequencies of CHPs for treating patients with hyperlipidemia in Taiwan. BACKGROUND Traditional Chinese medicine (TCM) has become popular as a therapy for controlling symptoms in patients with hyperlipidemia. This study aimed to analyze the prescription patterns of TCM for patients with hyperlipidemia in Taiwan. METHODS The study population was recruited from a random-sampled cohort of 1,000,000 people from the National Health Insurance Research Database between 2003 and 2009. We identified 30,784 outpatient visits related with hyperlipidemia diagnosis and collected these medical records. Association rules of data mining were conducted to explore the co-prescription patterns for Chinese herbal products (CHPs). RESULTS The most commonly prescribed herbal formula for hyperlipidemia treatment was Xue-Fu-Zhu-Yu-Tang (16.1%), and Shan Zha (Crataegi fructus; 25.0%) was the most commonly prescribed single herb. The most commonly prescribed combination of an herbal formula and a single herb was Xue-Fu-Zhu-Yu-Tang and Dan Shen (Radix Salviae Miltiorrhizae), and the most commonly prescribed combination of couplet herbs was Dan Shen and Shan Zha. CONCLUSION Xue-Fu-Zhu-Yu-Tang is the most frequently prescribed formula and is typically prescribed with Shan Zha, Dan Shen, and He Shou Wu for patients with hyperlipidemia. Clinical trials are warranted in future research to investigate the effects of the CHPs in terms of safety and efficacy and in particular to evaluate potential interactions with conventional treatments.

Evaluation of a crataegus-based multiherb formula for dyslipidemia: a randomized, double-blind, placebo-controlled clinical trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:365742. [PMID: 24834096 PMCID: PMC4009229 DOI: 10.1155/2014/365742] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/17/2013] [Revised: 03/19/2014] [Accepted: 03/22/2014] [Indexed: 11/17/2022]
Abstract
Background. We for the first time examined the effects of a multiherb formula containing Crataegus pinnatifida (1 g daily), Alisma orientalis, Stigma maydis, Ganoderma lucidum, Polygonum multiflorum, and Morus alba on plasma lipid and glucose levels in Chinese patients with dyslipidemia. Methods. In this randomized, double-blind, placebo-controlled study, 42 patients were randomized at a ratio of 1 : 1 to receive the herbal formula or placebo for 12 weeks and 40 patients completed the study. Lipid profiles, glucose, glycated haemoglobin (HbA1c), and laboratory safety parameters were performed before and after treatment. Results. The difference in the changes in low-density lipoprotein cholesterol (LDL-C) levels between placebo and active treatment (-9%) was significantly (P < 0.05) better with active treatment. HbA1c levels significantly decreased by -3.9% in the active treatment group, but the change was not significantly different from that with placebo (-1.1%) (P = 0.098). There were no apparent adverse effects or changes in laboratory safety parameters with either treatment. Conclusions. The multiherb formula had mild beneficial effects on plasma LDL-C after 12-weeks treatment in subjects with dyslipidemia without any noticeable adverse effects.

Abstract
The plant species Arbutus unedo shows numerous beneficial pharmacological effects (antiseptic, antidiabetic, antidiarrheal, astringent, depurative, antioxidant, antihypertensive, antithrombotic, and anti-inflammatory). For the medicinal use, standardization of extracts is a necessity, as different compounds are responsible for different biological activities. In this paper, we analyze monthly changes in the content of quercitrin, isoquercitrin, hyperoside, and chlorogenic acid. Methanolic extracts of the leaves are analyzed by HPTLC for the identification and quantification of individual polyphenol, and DPPH test is used to determine antioxidant activity. Based on the results obtained, the leaves should be collected in January to obtain the highest concentrations of hyperoside and quercitrin (0.35 mg/g and 1.94 mg/g, resp.), in June, July, and October for chlorogenic acid (1.45-1.46 mg/g), and for the fraction of quercitrin and isoquercitrin in November (1.98 mg/g and 0.33 mg/g, resp.). Optimal months for the collection of leaves with the maximum recovery of individual polyphenol suggested in this work could direct the pharmacological usage of the polyvalent herbal drugs.

Polyphenolic profile and biological activity of Chinese hawthorn (Crataegus pinnatifida BUNGE) fruits. Molecules 2012; 17:14490-509. [PMID: 23222867 PMCID: PMC6268084 DOI: 10.3390/molecules171214490] [Citation(s) in RCA: 93] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2012] [Revised: 11/26/2012] [Accepted: 11/29/2012] [Indexed: 02/06/2023] Open
Abstract
Chinese hawthorn (Crataegus pinnatifida Bge.) fruits are rich in polyphenols (e.g., epicatechin, procyanidin B2, procyanidin B5, procyanidin C1, hyperoside, isoquercitrin and chlorogenic acid)—active compounds that exert beneficial effects. This review summarizes all information available on polyphenolic content and methods for their quantification in Chinese hawthorn berries and the relationships between individual polyphenolic compounds as well. The influence of species or cultivars, the locality of cultivation, the stage of maturity, and extract preparation conditions on the polyphenolic content were discussed as well. Currently, only fruits of C. pinnatifida and C. pinnatifida var. major are included in the Chinese Pharmacopoeia. Recent trials have demonstrated the efficacy of Chinese hawthorn fruit in lowering blood cholesterol and the risk of cardiovascular diseases. The fruit has also demonstrated anti-inflammatory and anti-tumour activities. This review deals mainly with the biological activity of the fruit related to its antioxidant properties.

Yang B, Liu P. Composition and health effects of phenolic compounds in hawthorn (Crataegus spp.) of different origins. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2012; 92:1578-90. [PMID: 22488722 DOI: 10.1002/jsfa.5671] [Citation(s) in RCA: 64] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2011] [Revised: 11/29/2011] [Accepted: 02/23/2012] [Indexed: 05/03/2023]
Abstract
Epicatechin, aglycons and glycosides of B-type oligomeric procyanidins and flavonols, phenolic acids and C-glycosyl flavones are the major groups of phenolic compounds in hawthorn (Crataegus spp). The total content of phenolic compounds is higher in the leaves and flowers than in the fruits. Procyanidins dominate in the fruits, whereas flavonol glycosides and C-glycosyl flavones are most abundant in the leaves. Genotype and developmental/ripening stage have strong impacts. Procyanidin glycosides and C-glycosyl flavones may be chemotaxonomic markers differentiating species and varieties of hawthorn. Future research shall improve the separation, identification and quantification of procyanidins with degree of polymerisation (DP) ≥ 6, procyanidin glycosides, C-glycosyl flavones and some flavonol glycosides. In vitro and animal studies have shown cardioprotective, hypolipidaemic, hypotensive, antioxidant, radical-scavenging and anti-inflammatory potentials of hawthorn extracts, suggesting different phenolic compounds as the major bioactive components. However, the varying and insufficiently defined composition of the extracts investigated, as a result of different raw materials and extraction methods, makes comparison of the studies very difficult. Clinical evidence indicates that some hawthorn extracts may increase the exercise tolerance of patients with congestive heart failure. More clinical studies are needed to establish the effects of hawthorn, especially in healthy humans.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM) formulas have been widely used in China since ancient times to treat certain diseases (e.g., phlegm, dampness and blood stasis). Recently, the effects of these medicines have been increasingly demonstrated to be helpful for hyperlipidemic patients. AIM OF THE STUDY This manuscript aims to describe the scientific evidence for the efficacy of TCM and attempts to identify potential TCM formulas for treating hyperlipidemia. MATERIALS AND METHODS TCM formulas approved by the State Food and Drug Administration of China (SFDA) were sourced from the official SFDA website (http://www.sda.gov.cn/). Human and animal evidence for the hypolipidemic effects of herbs from TCM formulas were reviewed via the Internet (Elsevier, ACS, Wiley Online Library, SpringerLink, PubMed, Web of Science, CNKI, Baidu, and Google) and libraries up to October 31, 2011. RESULTS More than 50 TCM formulas have been used to treat hyperlipidemia. These herbs can primarily be grouped into three categories: (1) herbs promoting excretions, generally by reducing food retention, enhancing purgative effects, and promoting diuresis and choleretic effects, e.g., Fructus Crataegi (), Radix Polygoni Multiflori (), Semen Cassiae (), and Radix et Rhizoma Rhei (), Rhizoma alismatis (), and Herba Artemisiae Scopariae (); (2) herbs acting on the cardiovascular system, generally by improving blood circulation based on TCM theories, e.g., Radix Salviae Miltiorrhizae (), Radix Puerariae (), Rhizoma Chuanxiong (), Flos Carthami (), and Folium Nelumbinis (); and (3) herbs that have tonic effects, e.g., Fructus Lycii (), Radix Ginseng (), and Radix Astragali (). CONCLUSIONS Three basic approaches, including excretory function enhancement, cardiovascular system improvement, and tonic effect reinforcement, are emerging among TCM formulas for the treatment of hyperlipidemia. These approaches may be useful in controlling blood lipid levels, preventing cardiovascular complications, and adjusting bodily functions in hyperlipidemic patients. However, solid evidence of the efficacy of these treatments is required.

Abstract
AIMS Traditional Chinese medicine (TCM) has been used for treating complex chronic diseases owing to their fewer side-effects, better patient tolerance and relatively less cost. The present work was carried out to study the anti-diabetic efficacy and mechanisms of 34 TCMs. MATERIALS AND METHODS Streptozotocin (STZ)-diabetic mice were orally administrated with corresponding herbal solution once a day for 4 weeks. At the end of experiment, the level of plasma glucose, malondialdehyde (MDA), the activity of superoxide dismutase (SOD) and the serum aldose reductase (AR) were determined, the effects of TCM extract on α-glucosidase and angiotensin-converting enzyme (ACE) in vitro were also evaluated. RESULTS 13 out of the 34 herbs showed a statistically significant plasma glucose lowering action compared with the diabetic control group. Biochemical analysis revealed that Atractylodes macrocephala, Codonopsis pilosula, Dioscorea opposite, Flos lonicerae and Pueraria lobata may retard the progression of diabetes via reduce the blood glucose level and prevent the increase of AR activity. Other tested herbs, such as Ramulus cinnamomi, Cinnamomum cassia, and Eucommia ulmoides, showed the antidiabetic ability by either prevent the decrease in SOD activity or suppress the increase of MDA. Zymologic assay reveals that Pueraria lobata and Anemarrhena asphodeloides showed the highest inhibition against α-glucosidase and ACE respectively. Interestingly, the post-treatment glucose levels and AR activity were positively correlated with kidney/body weight of 34 herbs treated diabetic mice (p = 0.02, 0.04 respectively). CONCLUSIONS Several potential antidiabetic herbs derived from Chinese traditional pharmacopeia such as Dioscorea opposite, Pueraria lobata, Codonopsis pilosula and Ramulus cinnamomi, have been found to exert a beneficial action on diabetes and diabetic complications via multi-mechanisms.
