Comment in Clin Mol Hepatol. 2026 Jul;32(3):1397-1399. doi: 10.3350/cmh.2025.1329. BACKGROUND/AIMS: Cholestatic liver disease (CLD) is a pathological condition characterized by impaired bile formation, secretion, and excretion. However, the key pathophysiological mechanisms of CLD remain elusive, and therapeutic efficacy is unsatisfactory. METHODS: We administered berberine (BBR) or dihydroberberine (dhBBR) in bile duct ligation-, ANIT-, and mdr2-/- CLD mouse models to evaluate the anti-CLD effect. We conducted fecal microbiota transplantation to determine the role of gut microbiota in BBR's effect. We conducted a randomized, controlled clinical trial to evaluate the effects of BBR in patients with CLD. RESULTS: Oral BBR alleviates cholestatic liver injury in multiple mouse models. Gut microbes can transform BBR into dhBBR, which suppresses 5-hydroxytryptamine (5-HT) production in gut enterochromaffin cells by antagonizing tryptophan hydroxylase 1 (TPH1) activity and downregulating Tph1 transcription. This further ameliorates CLD by interrupting the 5-HT/5-HTR axis. A clinical study validated that BBR improved blood biochemical indicators in patients with CLD and decreased 5-HT levels. CONCLUSIONS: BBR is transformed by gut microbiota to ameliorate CLD via inhibiting 5-HT, suggesting potential novel strategies for further clinical use.

BACKGROUND: We assumed that the pharmacokinetics of lovastatin could be changed by the induction effect of berberine. METHODS: An UPLC-MS/MS method was developed and validated for the pharmacokinetics tudy of lovastatin to investigate the in vivo drug-drug interactions between lovastatin and berberine. SD male rats were random divided into lovastatin group and berberine induced prior to lovastatin group for the in vivo pharmacokinetic studies. Meanwhile HepG2 cells were induced by berberine for three days to study the metabolism of lovastatin. RESULTS: The AUC (p < 0.01) and Cmax (p < 0.01) could be significantly decreased in the berberine-induced group in vivo, and the metabolic activity of HepG2 cell ccould be increased by berberine induction in vitro. The metabolism parameters of lovastatin such as CL, Vmax and Km were increased after the induction of berberine. From the pharmacokinetic study of lovastatin induced with berberine, we obtained pharmacokinetic parameters which are compliance with the metabolic parameters of lovastatin in HepG2 cells with berberine induction in vitro. CONCLUSIONS: From the in vivo pharmacokinetics study and the HepG2 cell metabolism study in vitro, berberine could be an inducer for the metabolism of lovastatin according to our previous research on berberine induction effects on HepG2 cells, which may be relevant to the fact that berberine possesses induction effects through the CYP 450 3A4 enzyme.

BACKGROUND: Traditional antibiotics are increasingly suffering from the emergence of multidrug resistance amongst pathogenic bacteria leading to a range of novel approaches to control microbial infections being investigated as potential alternative treatments. One plausible antimicrobial alternative could be the combination of conventional antimicrobial agents/antibiotics with small molecules which block multidrug efflux systems known as efflux pump inhibitors. Bioassay-driven purification and structural determination of compounds from plant sources have yielded a number of pump inhibitors which acted against gram positive bacteria. METHODOLOGY/PRINCIPAL FINDINGS: In this study we report the identification and characterization of 4',5'-O-dicaffeoylquinic acid (4',5'-ODCQA) from Artemisia absinthium as a pump inhibitor with a potential of targeting efflux systems in a wide panel of gram-positive human pathogenic bacteria. Separation and identification of phenolic compounds (chlorogenic acid, 3',5'-ODCQA, 4',5'-ODCQA) was based on hyphenated chromatographic techniques such as liquid chromatography with post column solid-phase extraction coupled with nuclear magnetic resonance spectroscopy and mass spectroscopy. Microbial susceptibility testing and potentiation of well know pump substrates revealed at least two active compounds; chlorogenic acid with weak antimicrobial activity and 4',5'-ODCQA with pump inhibitory activity whereas 3',5'-ODCQA was ineffective. These initial findings were further validated with checkerboard, berberine accumulation efflux assays using efflux-related phenotypes and clinical isolates as well as molecular modeling methodology. CONCLUSIONS/SIGNIFICANCE: These techniques facilitated the direct analysis of the active components from plant extracts, as well as dramatically reduced the time needed to analyze the compounds, without the need for prior isolation. The calculated energetics of the docking poses supported the biological information for the inhibitory capabilities of 4',5'-ODCQA and furthermore contributed evidence that CQAs show a preferential binding to Major Facilitator Super family efflux systems, a key multidrug resistance dete

Isoflavones isolated from Lupinus argenteus were found to potentiate the antibacterial activity of alpha-linolenic acid, also found in the same plant. The isoflavones also potentiated the activity of the natural plant antibiotic berberine and the synthetic fluoroquinoline antibiotic norfloxacin. The isoflavones increased the uptake of berberine into Staphylococcus aureus cells, indicating that they may be inhibiting a multidrug resistance pump (MDR). Thus, L. argenteus contains a weak antibacterial and also MDR pump inhibitors, which increase its potency.

The urotoxicity of cyclophosphamide and the protective effect of the herb berberine were investigated in this study. Administration of 150 mg/kg cyclophosphamide intraperitoneally caused a serious haemorrhagic cystitis in rats after 12 hr, including bladder oedema, haemorrhage, and dramatic elevation of nitric oxide metabolites (nitrite+nitrate) in urine and in plasma. To explore whether cyclophosphamide-induced cystitis could be prevented by berberine, rats were pretreated with a single dose or two doses of berberine at 50, 100, or 200 mg/kg intraperitoneally then challenged with cyclophosphamide (150 mg/kg, intraperitoneally). The results indicated that pretreatment of rats with berberine could reduce cyclophosphamide-induced cystitis in a dose-dependent manner. Furthermore, we found that two doses of berberine showed greater protection against cyclophosphamide urotoxicity than when given a single dose. In addition, our data shows that a single dose of 200 mg/kg berberine, or two doses of 100, and 200 mg/kg berberine could completely block cyclophosphamide-induced bladder oedema and haemorrhage, as well as nitric oxide metabolites increase in rat urine and plasma. In conclusion, our findings suggest that berberine could be a potential effective drug in the treatment of cyclophosphamide-induced cystitis, and provides us with the bright hope in the prevention and treatment of cyclophosphamide urotoxicity.

BACKGROUND: Diabetes is a serious global health issue and increases the risk of several chronic diseases. However, if hyperglycemia and other metabolic abnormalities related to diabetes are controlled, fewer micro- and macrovascular complications may occur. OBJECTIVE: To investigate whether daily supplementation with berberine in combination with cinnamon could have effect on cardiometabolic risk factors, such as impaired glucose regulation, dyslipidemia, and hypertension in patients with diabetes. METHODS: Patients with type 2 diabetes were recruited to participate in a parallel, double-blind, placebo-controlled, randomized study. Participants were randomized into berberine in combination with cinnamon supplementation or placebo group. Participants were then asked to take a divided daily dose of 1200 mg berberine and 600 mg cinnamon or placebo for 12 weeks. ANCOVA was then performed to evaluate the differences between the two groups, controlling for the respective baseline values. RESULTS: At the end of study, fasting blood sugar (FBS) (P = 0.031) and hemoglobin A1C (HbA1c) (P = 0.013) were significantly lower in participants taking berberine plus cinnamon than those taking the placebo capsules. The results of the serum lipid profile also indicated a significant difference in the level of low density lipoprotein cholesterol (LDL-C) (P = 0.039), while no difference was observed in the levels of total cholesterol, high density lipoprotein cholesterol (HDL-C), and triglycerides between the study groups. In addition, there was no difference in other measured metabolic and anthropometric parameters between the two groups. CONCLUSION: Twelve weeks of berberine plus cinnamon consumption reduced blood FBS, HbA1c and LDL-C concentration in patients with diabetes. © 2025.

Pharmacokinetic drug interactions can lead to unexpected changes in plasma concentrations of the object drug, potentially increasing the risk for adverse effects and/or decreasing therapeutic efficacy. The botanical product goldenseal was previously shown to decrease metformin systemic exposure in healthy adults. This three-arm, open-label, crossover clinical study assessed the pharmacokinetic goldenseal-metformin interaction in adults with type 2 diabetes stabilized on therapeutic doses of metformin (500-2550 mg daily). The aggregate pharmacokinetic data indicated no clinically meaningful interaction as determined by the metformin area under the plasma concentration-time curve (AUC) geometric mean ratio [90% confidence interval] of 0.93 [0.86-1.01] laying within the predefined no-effect range (0.80-1.25). However, metformin AUC decreased by ~20%, 14%, and 0% after goldenseal coadministration at low (500-750 mg), moderate (1000-1500 mg), and high (2000-2550 mg) metformin doses, respectively; renal clearance and half-life remained unchanged throughout. The exploratory pharmacodynamic endpoint, HbA1c, decreased on average from 6.8% to 6.5%, regardless of the effects of goldenseal on metformin pharmacokinetics. The decreasing effect of goldenseal on metformin systemic exposure with increasing metformin dose, coupled with no changes in renal excretion and elimination half-life, indicated that both the pharmacokinetic goldenseal-metformin interaction and the nonlinear absorption of metformin are governed by saturable, intestinal transport mechanism(s). The disconnect between changes in metformin systemic exposure and therapeutic effects emphasizes the need to evaluate clinical biomarkers to comprehensively assess drug interaction risks, particularly those involving natural products. Healthcare providers may consider cautioning patients about supplementing metformin pharmacotherapy with goldenseal to avoid risks for undesired changes in glycemic control.

Objective: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a chronic condition affecting a broad population. This review aimed to identify and summarize the current evidence on bioactive-substance-based interventions for adults with MASLD, formerly known as nonalcoholic fatty liver disease (NAFLD), covering publications from 2000 to 2023. Methods: A search was conducted across six databases (MEDLINE, CINAHL, Cochrane CENTRAL, Cochrane Database of Systematic Reviews, Food Science Source, and SPORTDiscus) for randomized controlled trials and other study types (e.g., prospective cohort studies and systematic reviews), reflecting the scoping nature of this review. The search was limited to studies in adults (>18 years old), with an intervention of interest and at least one comparator group. Results: A total of 4572 articles were retrieved, with 201 full-text articles screened for eligibility. Of these, 131 primary studies and 49 systematic reviews were included in the scoping review. The most studied bioactive substances were Curcumin (Turmeric) (n = 25), Silymarin (Milk Thistle) (n = 17), Resveratrol (n = 10), Coffee (n = 7), Green Tea (n = 5), and Berberine (n = 5 each). Moreover, 46 studies reported on 36 other bioactive substances with 2 or fewer articles each. Among the included systematic reviews, 13 focused on Curcumin, 12 on Coffee or Tea, 10 on bioactive substance combinations, 6 on Resveratrol, and 2 each on Silymarin and Artichoke Leaf. The included studies showed substantial heterogeneity in reported outcomes, which primarily focused on hepatic health, body weight, adverse events, glycemic control, blood lipids, and body composition. Conclusions: This scoping review highlights a range of bioactive substances used in the treatment of MASLD. While evidence is abundant for bioactive substances like Curcumin and Silymarin, further research and synthesis of findings is necessary to establish the clinical efficacy of all bioactive substances.

The US dietary supplement (DS) market has expanded exponentially since 1994, with an estimated 50,000-80,000 individual products currently available. Many DS claim cholesterol or cardiovascular benefits. Overall, well-designed randomized controlled trials (RCTs) with DS are lacking, while studies with favorable results are commonly performed outside of the USA, resulting in inconsistent findings. The expansion of the DS market has limited the ability of the Food and Drug Administration to regulate and prevent substandard products. Eicosapentaenoic acid and docosahexaenoic acid are components of DS fish oil. Recent RCTs utilizing prescription fish oil have provided mixed findings and small but significant safety concerns. Hence, the role of DS fish oil is limited and no longer recommended by major cardiovascular guidelines. Concerns have also been observed from RCTs utilizing prescription niacin, resulting in a negligible role for DS niacin in lipid management. Red yeast rice has demonstrated significant low-density lipoprotein cholesterol (LDL-C) reductions in studies performed worldwide, including the USA. However, quality concerns and inconsistent study results have been reported on multiple occasions. Other common DS have produced modest reductions in LDL-C and may provide other cardiometabolic benefits, including garlic, phytosterols, psyllium, and berberine. Yet inconsistent study results and quality concerns continue to be reported for most. Nonetheless, there is a need for alternative therapies that can safely and effectively reduce cardiovascular risk. However, until DS routinely match label claims and are free of contaminants, the agents have a limited role in clinical practice. © 2024.

This study compared the capacity of two different models of HIIT [high-(HC) and low-(LC) compression], with or without the use of berberine (BBR), on NOD-like receptor pyrin domain-containing protein-3 (NLRP3), H19, interleukin (IL)-1β, high-sensitivity C-reactive protein (hs-CRP), and insulin resistance markers. Fifty-four middle-aged men with overweight or obesity and prediabetes [fasting blood glucose (FBG) 110-180 mg/dL] were randomly and equally assigned to the HC, LC, HC + BBR, LC + BBR, BBR, and non-exercising control (CON) groups. The HC (2:1 work-to-rest) and LC (1:1 work-to-rest) home-based training programs included 2-4 sets of 8 exercises at 80%-95% HRmax, twice a week for 8 weeks. Participants in the berberine groups received approximately 1000 mg daily. All exercise interventions led to a significant reduction in hs-CRP, IL-1β, insulin, FBG, and insulin resistance index (HOMA-IR) versus CON. Notably, there was a significant reduction in FBG and HOMA-IR with the BBR group compared to the baseline. Both NLRP3 and H19 experienced a significant drop only with LC in comparison to the baseline. While both exercise protocols were beneficial overall, LC uniquely exhibited more anti-inflammatory effects, as indicated by reductions in H19 and NLRP3. However, the addition of berberine to the exercise programs did not demonstrate additional benefits. © 2024 The Author(s).

This review aims to analyse the efficacy of dietary supplements in reducing plasma cholesterol levels. Focusing on evidence from meta-analyses of randomised controlled clinical trials, with an emphasis on potential mechanisms of action as supported by human, animal, and cell studies. Certain dietary supplements including phytosterols, berberine, viscous soluble dietary fibres, garlic supplements, soy protein, specific probiotic strains, and certain polyphenol extracts could significantly reduce plasma total and low-density lipoprotein (LDL) cholesterol levels by 3-25% in hypercholesterolemic patients depending on the type of supplement. They tended to be more effective in reducing plasma LDL cholesterol level in hypercholesterolemic individuals than in normocholesterolemic individuals. These supplements worked by various mechanisms, such as enhancing the excretion of bile acids, inhibiting the absorption of cholesterol in the intestines, increasing the expression of hepatic LDL receptors, suppressing the activity of enzymes involved in cholesterol synthesis, and activating the adenosine monophosphate-activated protein kinase signalling pathway.

Background: Berberine is a poorly absorbed natural alkaloid widely used as nutraceutical to counteract diarrhoea and to lower cholesterol and hyperglycaemia. It has also been reported to reduce signs and symptoms of polycystic ovary syndrome (PCOS). Objective: To explore, through a multi-centric, randomized, controlled and prospective study, the possible role played by a form berberine that is more easily absorbed (Berberine Phytosome®, BP) in 130 Pakistani women with a diagnosis of PCOS and fertility problems due to menstrual and ovary abnormalities. Results: Ninety days of supplementation with BP, administered at 550 mg x2/die, determined (i) resumption of regular menstruation in about 70% of women (versus 16% in the control group; p < 0.0001), (ii) normalization of the ovaries anatomy in more than 60% of women (versus 13% in the control group; p < 0.0001), (iii) acne improvement in 50% of women (versus 16% in the control group; p = 0.0409) and (iv) hirsutism reduction in 14% of women (versus 0% in the control group; p = 0.0152). The metabolic and the hormonal profiles of the women in the two groups did not significantly differentiate at the end of the study. BP was well-tolerated and no specific side-effects were registered. Respectively after one, two and 8 years of trying, three women supplemented with BP became and are currently pregnant. Conclusion: Our study showed the positive effects of BP supplementation in women with PCOS and confirmed the high safety profile of this nutraceutical.

PURPOSE: Several meta-analyses reported berberine (BBR) supplementation improves glycemic parameters and inflammatory marker, but findings remain inconsistent. Therefore, this study was conducted. METHODS: We systematically searched PubMed, Embase, Web of Science, Scopus, and Google Scholar to identify the relevant meta-analyses up to April 2023. FINDINGS: BBR supplementation was effective in reducing fasting blood glucose (FBG) (ESWMD: -0.77; 95% CI: -0.90 to -0.63, and ESSMD: -0.65; 95% CI: -0.83 to -0.47), hemoglobin A1C (HbA1C) (ESWMD: -0.57; 95% CI: -0.68 to -0.46), homeostasis model assessment for insulin resistance (HOMA-IR) (ESWMD: -1.04; 95% CI: -1.66 to -0.42, and ESSMD: -0.71; 95% CI: -0.97 to -0.46), insulin (ESWMD: -1.00; 95% CI: -1.70 to -0.30, and ESSMD: -0.63; 95% CI: -0.94 to -0.32), interleukin (IL)-6 (ESSMD: -1.23; 95% CI: -1.61 to -0.85), tumor necrosis factor-α (TNF-α) (ESSMD: -1.04; 95% CI: -1.28 to -0.79), and C-reactive protein (CRP) (ESWMD: -0.62; 95% CI: -0.74 to -0.50, and ESSMD: -1.70; 95% CI: -2.21 to -1.19). IMPLICATIONS: The finding of our umbrella showed that the supplementation of BBR could be effective in improving glycemic parameters and inflammatory marker in adults.

INTRODUCTION: There is growing interest in head-to-head comparison between different lipid-lowering nutraceuticals. The aim of our study was to test the lipid-lowering effect of dietary supplementation with low-dose monacolins from red yeast rice (2.8 mg per daily dose) combined with berberine (Armolipid Plus®) or highly standardized artichoke extract versus placebo. MATERIAL AND METHODS: 60 overall healthy adult volunteers with polygenic hypercholesterolemia (baseline low-density lipoprotein cholesterol (LDL-C) = 160.2 ±9.2 mg/dl) were enrolled in a 3-arm, double-blind, non-inferiority, randomized, parallel-group clinical trial. After 4-week diet standardization, enrolled individuals were randomized to be treated for 8 weeks with red yeast rice and highly standardized artichoke extracts (ATC group), Armolipid Plus®, or placebo. RESULTS: At the enrolment visit, LDL-C values were similar in the compared groups. After 8 weeks, all actively treated subjects experienced significant improvements in baseline total cholesterol (TC), LDL-C and apolipoprotein B (Apo-B) (all p < 0.01) (ATC group: TC = -18.9%, LDL-C = -26.7% (placebo-corrected: -12.4%), Apo-B = -19.6%; Armolipid Plus®: TC = -18.4%, LDL-C = -25.8% (placebo-corrected: -12.1%), Apo-B = -23.2%; placebo: TC = -6.2%, LDL-C = -8%, Apo-B = -8.4%). Participants in the ATC group attained significantly lower body mass index (BMI) values (-2.1%), while individuals treated with Armolipid Plus® showed improvements in baseline high-density lipoprotein cholesterol (HDL-C) (+8.7%) and triglyceride (TG) (+17.5%) levels. Finally, baseline hepatic steatosis index (HSI) values significantly decreased in both actively treated groups (by -2.4% and -2.4% in ATC and in Armolipid Plus®, respectively). CONCLUSIONS: Patients with polygenic hypercholesterolemia experienced a significant improvement in several cardiovascular risk factors in both ATC and Armolipid Plus® groups.

The previous meta-analysis showed an advantageous effect of berberine supplementation on interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), and serum C-reactive protein (CRP) concentrations; however, it is unknown the dosage that this component influences inflammatory biomarkers. A comprehensive search was done in Scopus, PubMed, and Web of Science until September 2022 to find randomized controlled trials (RCT) that assessed the effects of berberine/barberry on IL-6, TNF-α, and CRP in adults but not trials without a control group. Studies bias was assessed using RoB 2. A random-effects model was performed to calculate the weighted mean difference (WMD). A dose-dependent effect was calculated. Eighteen clinical trials with 1600 participants were included in the current meta-analysis. These interventions significantly mitigate IL-6 levels (-1.18 pg/mL), TNF-α levels (-3.72 pg/mL), and CRP levels (-1.33 mg/L). In addition, the non-linear analysis showed a significant lowering effect of berberine/barberry on IL-6 and TNF-α levels in doses <1000 mg/day and less than 5 weeks of intervention. There are limitations to our findings, including low-quality studies and significant heterogeneity. These interventions might be considered adjunct therapy to managing inflammation status. However, more investigation and high-quality evidence must be conducted to obtain more comprehensive and generalizable results. © 2023 John Wiley & Sons Ltd.

BACKGROUND: Berberine is widely available as a nutraceutical supplement for improving glucose metabolism. Berberine affects sex hormones, raising the possibility that its effects on glycemic traits and insulin sensitivity have sex disparity which has been overlooked. OBJECTIVE: To assess the overall and sex-specific effects of berberine on glycemic- and insulin-related traits. METHODS: We identified randomized trials of berberine versus placebo from Medline, Embase, CNKI, clinical trial registries and previous systematic reviews. Mean differences were estimated using inverse-variance weighting with random effects models. Subgroup analyses were conducted by sex, diabetes diagnosis, trial duration, berberine dose and ethnicity. RESULTS: We identified 20 eligible studies (n = 1761). Berberine lowered fasting glucose (-0.52 mmol/L, 95% CI -0.72 to -0.33; 18 studies, n = 1522), HbA1c (-4.48 mmol/mol, 95% CI -6.53 to -2.44, 7 studies, n = 756), fasting insulin (-2.36 mU/L, 95% CI -3.64 to -1.08, 11 studies, n = 966), HOMA-IR (-0.85, 95% CI -1.16 to -0.53,12 studies, n = 1065), and 2-h postprandial glucose (-1.81 mmol/L, 95% CI -2.37 to -1.24, 4 studies, n = 501). Effects on fasting glucose and HOMA-IR showed potential differences by sex, with larger reductions in women than in men. Comparing 4 studies conducted in women to one study conducted in men, the mean difference was -0.21 mmol/L (95% CI -0.41 to -0.00) for fasting glucose and -0.97 (95% CI -1.84 to -0.10) for HOMA-IR. We also found larger reductions in fasting glucose in participants with diabetes and in Asians. CONCLUSION: Berberine is effective in improving glucose metabolism and may result in larger effects on fasting glucose in women, in people with diabetes and in Asians, but subgroup comparisons remain to be replicated given the limited number of studies. Berberine can be considered as a complementary intervention in individuals who may benefit from modest improvements in glucose metabolism and who prefer taking a nutraceutical.

OBJECTIVE: Berberine is a plant alkaloid known to exert positive metabolic effects. Human studies have confirmed its ability to improve the lipid and glycemic profile. This study aimed to evaluate the potential benefit of oral supplementation of Berberine PhytosomeTM (2 tablets/day, 550 mg/tablet) on the metabolic profile of subjects with impaired fasting blood glucose (IFG). PATIENTS AND METHODS: A total of 49 overweight subjects, 28 females and 21 males, were randomly assigned to either the supplemented group (n=24) or placebo (n=25). We considered glycemia as the primary endpoint and total cholesterol, high-density lipoprotein (HDL), total cholesterol/HLD, low-density lipoprotein (LDL), LDL/HDL, triglycerides, insulin, glycated hemoglobin, Homeostasis Model Assessment (HOMA), ApoA, ApoB, ApoB/ApoA, androgen suppression treatment (AST), alternative lengthening of telomeres (ALT), gamma-glutamyl transferase (GGT), creatinine, and body composition by dual-energy X-ray absorptiometry (DXA) as secondary endpoints. These parameters have been assessed at baseline, after 30 days, and after 60 days. RESULTS: After two months of treatment, through the use of linear mixed effect models, a statistically significant difference between supplemented and placebo groups was observed for glycemia [β=-0.2495% C.I. (-0.47; -0.06), p=0.004], total cholesterol [β=-0.25, 95% C.I. (-0.45; -0.04), p=0.05], total cholesterol/HDL [β=-0.25, 95% C.I. (-0.43; -0.06), p=0.04], triglycerides [β=-0.14, 95% C.I. (-0.25; -0.02), p=0.05], insulin [β=-1.78, 95% C.I. (-2.87; -0.66), p=0.009], ApoB/ApoA [β=-0.08, 95% C.I. (-0.13; -03), p=0.004], Visceral adipose tissue (VAT) [β=-91.50, 95% C.I. (-132.60; -48.19), p<0.0001] and fat mass [β=-945.56, 95% C.I. (-1,424.42; -441.57), p=0.004]. CONCLUSIONS: The use of berberine had no adverse events, supporting its use as a natural alternative to pharmacological therapies in the case of IFG.

CONTEXT: Lyme disease is the most common, tick-borne disease in the USA. While most patients successfully recover with antibiotics, some patients experience persistent symptoms for months to years. Patients who attribute chronic symptoms to Lyme disease commonly use herbal supplements. The complexity, variability in dose and formulation, and lack of data for these herbal compounds make it difficult to assess their efficacy and safety. OBJECTIVE: This review examines the evidence for the antimicrobial activity, safety, and drug-drug interactions of 18 herbal supplements that patients commonly use for treatment of persistent symptoms attributed to Lyme disease. DESIGN: The research team performed a narrative review by searching the PubMed, Embase, Scopus, Natural Medicines databases, and NCCIH website. The search used the keywords for 18 herbal compounds: (1) andrographis (Andrographis paniculate), (2) astragalus (Astragalus propinquus), (3) berberine, (4) cat's claw bark (Uncaria tomentosa), (5) cordyceps (Cordyceps sinensis), (6) cryptolepis (Cryptolepis sanguinolenta), (7) Chinese skullcap (Scutellaria baicalensis), (8) garlic (Allium sativum), (9) Japanese knotwood (Polygonum cuspidatum), (10) reishi mushrooms (Ganoderma lucidum), (11) sarsaparilla (Smilax medica), (12) Siberian ginseng (Eleutherococcus senticosus), (13) sweet wormwood (Artemisia annua), (14) teasle root (Dipsacus fullonum), (15) lemon balm (Melissa officinalis), (16) oil of oregano (Origanum vulgare), (17) peppermint (Mentha x piperita), and (18) thyme (Thymus vulgaris). The team also searched for terms related to protocols, including Dr. Rawls' protocol and the Buhner protocol. SETTING: University of Maryland Medical Center, Baltimore MD. RESULTS: Seven of the 18 herbs reviewed had evidence for in-vitro activity against B. burgdorferi. These compounds included: (1) cat's claw (2) cryptolepis, (3) Chinese skullcap, (4) Japanese knotweed, (5) sweet wormwood, (6) thyme, and (7) oil of oregano. With the exception of oil of oregano these compounds also have anti-inflammatory activity. In vivo data and clinical trials are lacking. Clinicians should be cautious as many of the identified compounds h

BACKGROUND: Berberine is a nutraceutical that can improve lipid metabolism. Berberine may also affect sex hormones and exert sex-specific lipid-modifying effects, which have been overlooked. This study aimed to comprehensively review the efficacy and safety of berberine in adults for the treatment of dyslipidemia with consideration of potential sex disparity. Data Sources We searched Medline, Embase, Wanfang, CNKI, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform from inception to 13 December 2022. No language restrictions were applied. This study was registered in PROSPERO (CRD42021293218) prior to completing the literature search. Study Selection Two blinded reviewers assessed studies for inclusion. Eligible studies were randomized controlled trials in adults that compared berberine versus placebo, and measured blood lipids or lipoproteins. Data Extraction and Synthesis Data extraction was performed by two blinded reviewers using a structured form in Covidence. Risk of bias was assessed using the Cochrane risk of bias tool for randomized trials. Mean differences (MD) were estimated using inverse variance weighting with random effects models for lipid outcomes using R. Adverse events (AEs) were described narratively. Main Outcomes Primary outcomes were low-density lipoprotein (LDL) cholesterol, total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, and apolipoprotein B. Secondary outcomes were gastrointestinal and muscle-related AEs. RESULTS: Eighteen studies (n = 1788 participants), conducted mainly in mainland China and Hong Kong (15 studies [83%]), were included with treatment durations ranging from 4 to 24 weeks. Berberine reduced LDL cholesterol (- 0.46 mmol/L, 95% CI - 0.62 to - 0.30, 14 studies, n = 1447), total cholesterol (- 0.48 mmol/L, 95% CI - 0.63 to - 0.33, 17 studies, n = 1637), triglycerides (- 0.34 mmol/L, 95% CI - 0.46 to - 0.23, 18 studies, n = 1661) and apolipoprotein B (- 0.25 g/L, 95% CI - 0.40 to - 0.11, 2 studies, n = 127). Berberine increased HDL cholesterol by 0.06 mmol/L (95% CI 0.00 to 0.11, 15 studies, n = 1471). Notably, the effect on HDL cholesterol was different in women (0.11

BACKGROUND & AIMS: Despite controversies, no study has systematically summarized findings from earlier studies on the effect of berberine (BBR)-silymarin on liver enzymes. Therefore, the current systematic review and meta-analysis aimed to investigate the effect of berberis aristate and Silybum marianum on alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in adults. METHODS: Relevant studies, published up to June 2021, were searched through PubMed/Medline, Scopus, ISI Web of Science, EMBASE and Google Scholar. The mean differences and standard deviations were pooled using a random-effects model. The studies' quality was evaluated using the Cochrane Risk of Bias Tool. RESULTS: Out of 80 citations, 5 trials that enrolled 549 participants were included. Berberis aristate and Silybum marianum resulted in no statistically significant change in ALT (weighted mean differences (WMD): -0.39 mg/dl; 95% CI: -1.67 to 0.89, P = 0.55), and AST (WMD: -0.44 mg/dl; 95% CI: -2.02 to 1.14, P = 0.58). CONCLUSION: We did not find any significant reduction in liver enzymes following BBR-silymarin consumption in adults. Further clinical trials with high quality according to the challenges mentioned seem to be helpful to use BBR-silymarin as a supplement for improving liver function.
