High-precision identification of highly similar Pinelliae Rhizoma and adulterated Rhizoma pinelliae pedatisectae through deep neural networks based on vision transformers.

Pinelliae Rhizoma is a key ingredient in botanical supplements and is often adulterated by Rhizoma Pinelliae Pedatisectae, which is similar in appearance but less expensive. Accurate identification of these materials is crucial for both scientific and commercial purposes. Traditional morphological identification relies heavily on expert experience and is subjective, while chemical analysis and molecular biological identification are typically time consuming and labor intensive. This study aims to employ a simpler, faster, and non-invasive image recognition technique to distinguish between these two highly similar plant materials. In the realm of image recognition, we aimed to utilize the vision transformer (ViT) algorithm, a cutting-edge image recognition technology, to differentiate these materials. All samples were verified using DNA molecular identification before image analysis. The result demonstrates that the ViT algorithm achieves a classification accuracy exceeding 94%, significantly outperforming the convolutional neural network model's 60%-70% accuracy. This highlights the efficiency of this technology in identifying plant materials with similar appearances. This study marks the pioneer work of the ViT algorithm to such a challenging task, showcasing its potential for precise botanical material identification and setting the stage for future advancements in the field.

Withania somnifera (Ashwagandha) Improves Spatial Memory, Anxiety and Depressive-like Behavior in the 5xFAD Mouse Model of Alzheimer's Disease.

Withania somnifera (WS), also known as ashwagandha, is a popular botanical supplement used to treat various conditions including memory loss, anxiety and depression. Previous studies from our group showed an aqueous extract of WS root (WSAq) enhances cognition and alleviates markers for depression in Drosophila. Here, we sought to confirm these effects in the 5xFAD mouse model of β-amyloid (Aβ) accumulation. Six- to seven-month-old male and female 5xFAD mice were treated with WSAq in their drinking water at 0 mg/mL, 0.5 mg/mL or 2.5 mg/mL for four weeks. In the fourth week of treatment, spatial memory, anxiety and depressive-like symptoms were evaluated. At the conclusion of behavioral testing, brain tissue was harvested, immunohistochemistry was performed, and the cortical expression of antioxidant response genes was evaluated. Both concentrations of WSAq improved spatial memory and reduced depressive and anxiety-related behavior. These improvements were accompanied by a reduction in Aβ plaque burden in the hippocampus and cortex and an attenuation of activation of microglia and astrocytes. Antioxidant response genes were upregulated in the cortex of WSAq-treated mice. Oral WSAq treatment could be beneficial as a therapeutic option in AD for improving disease pathology and behavioral symptoms. Future studies focused on dose optimization of WSAq administration and further assessment of the mechanisms by which WSAq elicits its beneficial effects will help inform the clinical potential of this promising botanical therapy.

Evaluating the Efficacy and Safety of Cymbopogon Schoenanthus Syrup for Asthma and Allergies: A Two-Decade Clinical Study

Asthma and allergies are prevalent respiratory conditions affecting millions worldwide, often necessitating long-term management and treatment. Synthetic medications, while effective, may pose risks and adverse effects, prompting exploration into natural alternatives. This study investigates the efficacy and safety of a botanical syrup supplement derived from Cymbopogon Schoenanthus subsp. proximus, known as “Binj” or “Abba” in the United Arab Emirates (UAE), for the management of asthma and allergies. Through collaborative efforts with reputable laboratories and universities, the botanical syrup’s therapeutic potential was rigorously evaluated, encompassing phytochemical analysis, biological testing, and extensive clinical trials spanning two decades. Results demonstrate notable improvements in lung function and skin health among patients with asthma and allergies, evidenced by enhanced vital capacity, forced vital capacity, and visible reduction in skin allergy symptoms. Furthermore, safety assessments indicate a favorable profile, with minimal adverse events reported. The recognition of the botanical syrup by the UAE Ministry of Health and international pharmaceutical companies underscores its significance and potential for widespread application. This discovery represents a promising advancement in natural medicine, offering a safe and effective alternative for individuals seeking holistic respiratory wellness. Future research should focus on large-scale clinical trials and long-term safety studies to further elucidate its therapeutic benefits and optimize clinical outcomes.

An Oral Botanical Supplement Improves Small Intestinal Bacterial Overgrowth (SIBO) and Facial Redness: Results of an Open-Label Clinical Study.

Small intestinal bacterial overgrowth (SIBO) is a common, yet underdiagnosed, gut condition caused by gut dysbiosis. A previous study has shown the potential of herbal therapy, providing equivalent results to rifaximin. The objective of this study was to assess how the use of an oral botanical regimen may modulate the gut microbiome, facial erythema, and intestinal permeability in those with SIBO. This was an open-label prospective study of adults that had lactulose breath test-confirmed SIBO. Participants received a 10-week oral supplementation of a Biocidin liquid tincture and GI Detox+. If participants were found to be non-responsive to treatment after 10 weeks with a persistently positive lactulose breath test, a third oral supplement, Olivirex, was administered for an additional 4 weeks. Lactulose breath tests were administered at baseline, weeks 6, 10, and 14 to assess for SIBO status. A high-resolution photographic analysis system was utilized to analyze changes in facial erythema. Stool sample collections and venipuncture were performed to analyze the gut microbiome and intestinal permeability. A total of 33 subjects were screened with breath testing, and 19 subjects were found to have SIBO. Three of the subjects withdrew during the screening period prior to baseline, and sixteen subjects enrolled. Four subjects dropped out after baseline. Hydrogen-dominant SIBO was the most common subtype of SIBO, followed by methane and hydrogen sulfide. The botanical regimen was most effective for hydrogen- and hydrogen sulfide-dominant SIBO, leading to negative breath test results at week 10 in 42.8% and 66.7% of participants, respectively. Compared to baseline, supplementation with the botanical regimen led to positive shifts in short-chain fatty acid-producing bacteria such as A. muciniphila, F. prausnitzii, C. eutectus, and R. faecis by 31.4%, 35.4%, 24.8%, and 48.7% percent at week 10, respectively. The mean abundance of Firmicutes decreased by 20.2%, Bacteroides increased by 30%, and the F/B ratio decreased by 25.4% at week 10 compared to baseline. At week 10, there was a trending 116% increase in plasma LPS/IgG (p = 0.08). There were no significant changes in plasma zonulin, DAO, histamine, DAO/histamine, LPS/IgG, LPS/IgA, or LPS/IgM. Facial erythema was not statistically different at week 6, but at week 10, there was a 20% decrease (p = 0.001) in redness intensity. Among the patients that extended to week 14, there was no statistical change in erythema. Supplementation with an antimicrobial botanical supplemental regimen may have therapeutic potential in hydrogen and hydrogen-sulfide subtypes of SIBO. Furthermore, the botanical supplemental regimen may reduce facial erythema, increase SCFA-producing bacteria, decrease the F/B ratio, and modulate markers of intestinal permeability.

Complementary and Alternative Therapies for Genitourinary Syndrome of Menopause : An Evidence Map.

Women seeking nonhormonal interventions for vulvovaginal, urinary, and sexual symptoms associated with genitourinary syndrome of menopause (GSM) may seek out complementary and alternative medicine or therapies (CAMs). To summarize published evidence of CAMs for GSM. Ovid MEDLINE, EMBASE, and CINAHL from inception through 11 December 2023. Randomized controlled trials (RCTs) 8 weeks or more in duration that evaluated the effectiveness or harms of CAMs for postmenopausal women with GSM and reported 1 or more outcomes of interest, with sample sizes of 20 or more participants randomly assigned per group. Data were abstracted by 1 reviewer and verified by a second. An evidence map approach was used to organize and describe trials. Studies were organized by type of intervention, with narrative summaries for population, study characteristics, interventions, and outcomes. Fifty-seven trials were identified that investigated 39 unique interventions. Studies were typically small (n < 200), and most were done in Iran (k = 24) or other parts of Asia (k = 9). Few trials evaluated similar combinations of populations, interventions, comparators, or outcomes. Most studies (k = 44) examined natural products (that is, herbal or botanical supplements and vitamins), whereas fewer reported on mind and body practices (k = 6) or educational programs (k = 7). Most studies reported 1 or 2 GSM symptoms, mainly sexual (k = 44) or vulvovaginal (k = 30). Tools used to measure outcomes varied widely. Most trials reported on adverse events (k = 33). Only English-language studies were used. Effect estimates, risk of bias, and certainty of evidence were not assessed. There is a large and heterogeneous literature of CAM interventions for GSM. Trials were small, and few were done in North America. Standardized population, intervention, comparator, and outcomes reporting in future RCTs are needed.

Analysis of US Marketed Artemisinin Supplements for Use in Dogs.

Oral artemisinin has antiparasitic activity and may help improve treatment success rates in dogs infected with Babesia gibsoni. However, these artemisinin products are unapproved and unregulated botanical supplements. They have not been evaluated for safety and efficacy or for strength, purity, or quality compared with a reference standard. Before considering these products for a clinical study, we evaluated the strength of four suppliers of artemisinin capsules using an high-performance liquid chromatography method validated in our laboratory. We found that the four artemisinin-labeled products that were tested had high within product and between product variability in capsule strength compared with the stated capsule strength on the product label. No products met the acceptance criteria of the United States Pharmacopeia and International Council for Harmonisation (ICH) as well as the criteria adapted by the authors. One product had no detectable artemisinin, and the other three products were much higher than the stated label strength. The results of this study reinforce the importance of testing unapproved and unregulated supplements before recommending a supplement for clinical use in dogs.

Helping athletes to select botanical supplements for the right reasons: A comparison of self-reported reasons for use versus evidence-based supplement claims.

Use of food supplements (FS) by athletes is well characterised but there is little information on 'herbal' or 'botanical' FS beyond 'natural'. This study determined, by questionnaire, whether athletes' main self-reported reason for using FS was reflective of what was written on product labels or, when these claims were unavailable, was in accordance with the scientific literature. In 217 elite (n = 55) and amateur (n = 162) athletes living on the island of Ireland, 71% (n = 153) consumed any kind of FS, with 16% (n = 34) of the entire cohort deemed botanical consumers. 'Protein' (21%, n = 46), 'vitamin D' (17%, n = 37) and 'vitamin C' (15% n = 32) were most consumed with the top reasons for use being 'to support health', 'to prevent illness/for immunity purposes' and 'recovery'. There was generally good agreement between approved nutrition and health claims for such products and athletes' main reported reasons for use. Only the amateur athletes in our pool described using botanical supplements, with reasons for use stated as 'sleep improvement' (21%), 'recovery' (14%), 'supporting health' (12%) and 'energy' (12%), resulting in poor agreement with either approved claims or scientific evidence. Only half of amateur athletes knew if their botanical FS were third-party tested. Athletes and practitioners require guidance to avoid consuming supplements for which there is little scientific evidence, and which may risk being contaminated/fraudulent.

Has Mutual Recognition in the EU Failed?—A Legal-Empirical Analysis on the Example of Food Supplements Containing Botanicals and Other Bioactive Substances

The European Union lacks comprehensive legislation pertaining to food supplements containing botanical or bioactive substances other than nutrients, resulting in disparate regulatory frameworks among European Member States. Previous studies predominantly focused on the doctrinal analysis of these diverse regulations at both European and national levels, offering limited insights into their practical implementation by governing bodies. This research endeavours to scrutinize administrative practices governing legislation on food supplements featuring botanical or other bioactive constituents, which are subject to varying approaches across Member States. Employing a combination of doctrinal and empirical legal research methodologies, this approach involved a meticulous examination of the regulatory landscape governing food supplements at both EU and Member State levels. Simultaneously, an empirical investigation, conducted through expert interviews, aimed to elucidate whether discrepancies among national legal systems translate into discernible variations in the operational strategies of competent authorities. Additionally, this empirical inquiry shed light on the efficacy of specific EU directives aimed at harmonizing food supplement regulations at the national level. These findings delineate a fragmented regulatory environment for botanical and bioactive food supplements across Member States. Noteworthy disparities were observed not only in national legislative frameworks but also in the enforcement practices of regulatory authorities. Union-level governance efforts in particular by adopting a mutual recognition approach to mitigate fragmentation proved ineffective. Consequently, this research underscores an urgent imperative to expedite the harmonization of regulations governing botanicals and other bioactive substances present in food supplements across the European Union.

Polyphenols and Lactation: Molecular Evidence to Support the Use of Botanical Galactagogues.

Botanicals and herbal supplements contain a diverse array of polyphenols that may affect mammary gland function and promote galactagogue activity. This scoping review is conducted to identify scientific literature elucidating how polyphenols affect mammary gland biology and cellular mechanisms critical for lactation. A literature search of PubMed and Medline reviews relevant studies in dairy animals, rodent models, and cultured mammary epithelial cells that are published from January 2010 until July 2023, to ascertain effects of polyphenols on mechanisms regulating milk production and composition. The PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review) strategy is applied and 80 studies on polyphenols and their implications on milk production and composition are included in this review. Limited information delineating effects of polyphenols on the molecular pathways that affect lactation are found, although available information suggests modulation of Stat5 signaling/differentiation, Stat3 signaling/remodeling, mTOR and insulin signaling/energy production, and nuclear factor kappa beta (NFκβ) signaling/oxidative stress and inflammation may play roles. A profound lack of mechanistic information underscores the critical need for further research to understand the impact of botanical supplements and polyphenols on milk production and composition in humans to establish maternal nutritional guidelines to support lactation and breastfeeding goals.

Integrated Multiplatform Analysis and Separation of Thirteen Flavonoids and Anthraquinones in Seven Medicinal Cassia Species.

Cassia (Family: Fabaceae) species are a large group of flowering plants rich in bioactive anthraquinone and flavonoids used in botanical supplements and nutraceuticals. A simple and reliable high-performance liquid chromatography-photodiode array (HPLC-PDA) method was developed and validated for separating and quantifying 13 anthraquinone and flavonoids. These compounds were further confirmed using an LC-based electrospray ionization mass spectrometry (ESI-MS/MS) method in the leaves and flowers of selected Cassia species. A simple and rapid HPTLC method was developed for chemical fingerprint analysis of all Cassia species. All 13 compounds were chromatographically separated on a Zorbax TC18 (4.6 × 250, 5 μm particle size) analytical column, and 0.1% formic acid and acetonitrile as elution solvents at a flow rate of 0.8 mL/min with detection at 259 nm. For HPTLC fingerprinting, the mobile phase compositions of toluene, ethyl acetate, and formic acid (5.5:4.2:0.6, v/v/v) were optimized to separate and identify all compounds using silica gel 60F254 aluminum plates. The validation data for the developed HPLC-PDA method for 13 compounds showed good linearity (r2 >0.99) with a sensitive LOD (0.082-1.969 μg/mL), LOQ (0.250-5.967 μg/mL), and excellent recoveries (85.22-100.32%). The quantification results were found to be precise and accurate (<5.0% and relative error), -0.77-0.44 with ESI-MS/MS confirmation in the Cassia samples. The novel HPTLC method was excellent separation for 13 compounds, with Rf values ranging between 0.12 and 0.61. The developed HPLC-PDA method was simple and precise and could separate and quantify anthraquinones and flavonoids along with confirmation, using a novel LC-based ESI-MS/MS. The HPTLC method was found to be simple and precise, with excellent separation capabilities for these compounds. This novel multiplatform approach successfully identified and quantified 13 compounds simultaneously using an integration of data strategy in seven medicinally important Cassia species' leaves and flowers.

Nutrition for Female Menopausal Cancer Survivors: Developing Ireland’s First Resource

Women diagnosed with a hormone-receptor positive (HR+) breast or gynaecological cancer are not routinely prescribed hormone replacement therapy to alleviate menopausal symptoms due to the risk of causing cancer recurrence. Many of these women use herbal or botanical supplements, diet and lifestyle interventions to provide relief. Through an extensive literature review, national focus groups with menopausal female cancer survivors, consultation with an established public and patient involvement panel, and the creation of a national review panel of medical and healthcare professionals, Ireland’s first evidence-based resource is in development for female menopausal cancer survivors.

PSIV-12 Dietary Supplementation of a Botanical Blend Improved Growth Performance and Reduced Diarrhea Incidence in Commercially Housed Weaned Pigs

Abstract The study evaluated the effects of dietary botanical supplementation on the growth performance and diarrhea incidence of commercially housed weaned piglets. The study design was a randomized complete block with two dietary treatments [control (CON) and botanical blend (BB)] and 36 replicate pens per treatment (16 pigs/pen, 576 pigs/treatment). All piglets were fed a three-phase feeding program: P1, days 1-10; P2, days 11-21; P3, days 21-42. Diets were corn-soy and contained 150 ppm total zinc; P1 and P2 diets also contained 250 ppm of chlortetracycline. The botanical supplement was included in the P1 and P2 BB diets at a rate of 250 ppm. Body weight (BW) and feed disappearance were recorded weekly to calculate average daily gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (FCR). Body condition scoring and diarrhea frequency and severity were measured weekly for the first 4 weeks. Data were analyzed using PROC GLMMIX of SAS with appropriate models for the different data distributions. Pen was the experimental unit. The overall herd mortality and culling rate were 0.17% and 3.04%, respectively. Further, more than 95% of the pigs were in good body condition and did not differ between treatments. Pigs fed BB had a greater survival rate at the end of the study (97.9 vs 95.7%; P = 0.01) and diarrhea incidence was reduced by 5% for pigs fed BB compared with CON. In early nursery (days 1-21), pigs fed BB had a lower FCR (1.21 vs. 1.23 kg/kg; P = 0.049) and greater ADG (0.276 vs. 0.267 kg/d; P = 0.016), resultant in heavier BW at day 21 (12.1 vs. 11.9 kg; P = 0.046) than those fed CON. Considering the entire nursery (days 1-42), pigs fed BB tended to have greater ADG (0.430 vs 0.421 kg/d; P = 0.06) and ADFI (0.580 vs. 0.568 kg/d; P = 0.054) overall compared with CON. In conclusion, dietary supplementation of the botanical blend reduced diarrhea incidence and significantly improved early (1-21 days post-weaning) growth performance and feed efficiency in commercially housed weaned piglets. These early growth benefits persisted to the end of the nursery period, as a tendency for increased growth rate and feed intake.

Interaction of Garcinia cambogia (Gaertn.) Desr. and Drugs as a Possible Mechanism of Liver Injury: The Case of Montelukast.

Overweight and obesity prevalence has increased worldwide. Apart from conventional approaches, people also resort to botanical supplements for reducing body weight, although several adverse events have been associated with these products. In this context, the present study aimed at evaluating the toxicity of Garcinia cambogia-based products and shedding light on the mechanisms involved. The suspected hepatotoxic reactions related to G. cambogia-containing products collected within the Italian Phytovigilance System (IPS) were examined. Then, an in vitro study was performed to evaluate the possible mechanisms responsible for the liver toxicity, focusing on the modulation of oxidative stress and Nrf2 expression. From March 2002 to March 2022, the IPS collected eight reports of hepatic adverse reactions related to G. cambogia, which exclusively involved women and were mostly severe. The causality assessment was probable in three cases, while it was possible in five. In the in vitro experiments, a low cytotoxicity of G. cambogia was observed. However, its combination with montelukast greatly reduced cell viability, increased the intracellular ROS levels, and affected the cytoplasmic Nrf2 expression, thus suggesting an impairment of the antioxidant and cytoprotective defenses. Overall, our results support the safety concerns about G. cambogia-containing supplements and shed light on the possible mechanisms underpinning its hepatotoxicity.

Network pharmacology-based strategic prediction and target identification of apocarotenoids and carotenoids from standardized Kashmir saffron (Crocus sativus L.) extract against polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a hormonal disorder that affects women of reproductive age, characterized by a range of symptoms, including irregular menstrual cycles, excess male hormones (androgens), metabolic abnormalities such as hyperinsulinemia, hyperlipidemia, and metabolic disturbances like glucose imbalance. Botanical supplements are perceived first and safe choice over available regimens to regulate PCOS. There are several reports available stating that apocarotenoids, carotenoids, and whole extracts of Crocus sativus were identified to have a potential role in the management of women health. This study aimed to propose a network pharmacology-based method to determine the potential therapeutic pathways of phytoconstituents (apocarotenoids and carotenoids) of UHPLC-PDA standardized stigma-based Crocus sativus extract (CSE) for the management of PCOS. Furthermore, to validate the potential targets and signaling pathways, these apocarotenoids, and carotenoids were screened for molecular docking and in silico absorption, distribution, metabolism, excretion, and toxicity (ADMET) predictions. The information regarding PCOS-related genes was retrieved from the PCOS knowledge database (PCOSKB), resulting in an established network between putative targets of PCOS and Crocus sativus extract phytochemicals to prevail the mechanism of action. Based on the screening conditions, 4 prominent targets namely, serine/threonine kinase 1 (AKT1), signal transducer and activator of transcription (STAT3), mitogen-activated protein kinase 3 (MAPK3), and mitogen-activated protein kinase 1 (MAPK1), were identified through network analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis suggested that MAP kinase and serine-threonine pathways were found prominent targets in PCOS. Further, a molecular docking study shows that crocetin, picrocrocin, and safranal had the best binding affinity for the identified targets. In silico ADMET results revealed that carotenoids and apocarotenoids were found to have the maximum bioavailability and were able to cross the blood-brain barrier without any toxic effects. The combined results revealed that the apocarotenoids and carotenoids of Crocus sativus extract could act on various targets to regulate multiple pathways related to PCOS.

A novel polyphenol-rich combination of 5 plant extracts prevents high-fat diet-induced body weight gain by regulating intestinal macronutrient absorption in mice

Global prevalence of obesity and type 2 diabetes are rapidly increasing to pandemic proportions. A novel supplement composed of 5 plant extracts from olive leaf, bilberry, artichoke, chrysanthellum, and black pepper was designed to prevent type 2 diabetes development in people at risk. It was previously shown to improve body weight and glucose control in preclinical rodent models, with these effects being accompanied by increased fecal energy excretion and in vitro inhibition of several digestive enzymes. Thus, we hypothesized that, in mice fed a high-fat diet (HFD), a single dose of this botanical supplementation would decrease the responses to oral fat and carbohydrate tolerance tests, and that chronic supplementation would result in increased fecal triglyceride content. We showed that acute administration in HFD-fed mice (1.452 g/kg body weight) markedly reduced circulating triglycerides following an oral lipid gavage, whereas glycemic responses to various carbohydrate tests were only mildly affected. When incorporated into the food (2.5%) of HFD-fed mice, chronic supplementation prevented body weight gain and improved glucose homeostasis and lipid tolerance. Fecal free fatty acid content, but not triglyceride, was significantly increased in supplemented animals, suggesting reduced lipid absorption in the digestive tract. Congruently, this botanical supplementation downregulated several genes associated with fatty acid transport whose expression was increased by HFD, principally in the jejunum. This study provides novel insights as for the mode of action behind the antiobesity effect of this plant-based supplementation, in HFD-fed mice.

Functional immune boosters; the herb or its dead microbiome? Antigenic TLR4 agonist MAMPs found in 65 medicinal roots and algae's.

Humans have been consuming medicinal plants (as herbs/ spices) to combat illness for centuries while ascribing beneficial effects predominantly to the plant/phytochemical constituents, without recognizing the power of obligatory resident microorganism' communities (MOCs) (live/dead bacteria, fungus, yeast, molds etc.) which remain after industrial microbial reduction methods. Very little is known about the taxonomic identity of residual antigenic microbial associated molecular patterns (MAMPs) debris in our botanical over the counter (OTC) products, which if present would be recognized as foreign (non-self) antigenic matter by host pattern recognition receptors (PRRs) provoking a host immune response; this the basis of vaccine adjuvants. As of today, only few research groups have removed the herbal MAMP biomass from herbs, all suggesting that immune activation may not be from the plant but rather its microbial biomass; a hypothesis we corroborate. The purpose of this work was to conduct a high through put screening (HTPS) of over 2500 natural plants, OTC botanical supplements and phytochemicals to elucidate those with pro-inflammatory; toll like receptor 4 (TLR4) activating properties in macrophages. The HTPS was conducted on RAW 264.7 cells vs. lipopolysaccharide (LPS) E. coli 0111:B4, testing iNOS / nitric oxide production as a perimeter endpoint. The data show not a single drug/chemical/ phytochemical and approximately 98 % of botanicals to be immune idle (not effective) with only 65 pro-inflammatory (hits) in a potency range of LPS. Method validation studies eliminated the possibility of false artifact or contamination, and results were cross verified through multiple vendors/ manufacturers/lot numbers by botanical species. Lead botanicals were evaluated for plant concentration of LPS, 1,3:1,6-β-glucan, 1,3:1,4-β-D-glucan and α-glucans; where the former paralleled strength in vitro. LPS was then removed from plants using high-capacity endotoxin poly lysine columns, where bioactivity of LPS null "plant" extracts were lost. The stability of E.Coli 0111:B4 in an acid stomach mimetic model was confirmed. Last, we conducted a reverse culture on aerobic plate counts (APCs) from select hits, with subsequent isolation of gram-negative bacteria (MacConkey agar). Cultures were 1) heat destroyed (retested/ confirming bioactivity) and 2) subject to taxonomical identification by genetic sequencing 18S, ITS1, 5.8 s, ITS2 28S, and 16S. The data show significant gram negative MAMP biomass dominance in A) roots (e.g. echinacea, yucca, burdock, stinging nettle, sarsaparilla, hydrangea, poke, madder, calamus, rhaponticum, pleurisy, aconite etc.) and B) oceanic plants / algae's (e.g. bladderwrack, chlorella, spirulina, kelp, and "OTC Seamoss-blends" (irish moss, bladderwrack, burdock root etc), as well as other random herbs (eg. corn silk, cleavers, watercress, cardamom seed, tribulus, duckweed, puffball, hordeum and pollen). The results show a dominance of gram negative microbes (e.g. Klebsilla aerogenes, Pantoae agglomerans, Cronobacter sakazakii), fungus (Glomeracaea, Ascomycota, Irpex lacteus, Aureobasidium pullulans, Fibroporia albicans, Chlorociboria clavula, Aspergillus_sp JUC-2), with black walnut hull, echinacea and burdock root also containing gram positive microbial strains (Fontibacillus, Paenibacillus, Enterococcus gallinarum, Bromate-reducing bacterium B6 and various strains of Clostridium). This work brings attention to the existence of a functional immune bioactive herbal microbiome, independent from the plant. There is need to further this avenue of research, which should be carried out with consideration as to both positive or negative consequences arising from daily consumption of botanicals highly laden with bioactive MAMPS.

Authentication of milk thistle commercial products using UHPLC-QTOF-ESI + MS metabolomics and DNA metabarcoding

BackgroundMilk thistle is one of the most popular hepatoprotectants, and is often sold in combination with other ingredients. Botanical supplements are known to be vulnerable to contamination and adulteration, and emerging technologies show promise to improve their quality control.MethodsUntargeted and semi-targeted metabolomics based on UHPLC-QTOF-ESI+MS techniques, UV spectrometry, and DNA metabarcoding using Illumina MiSeq were used to authenticate eighteen milk thistle botanical formulations (teas, capsules, tablets, emulsion).ResultsUntargeted metabolomics separated 217 molecules and by multivariate analysis the discrimination between the different preparations was established. The semi-targeted metabolomics focused on 63 phytochemicals, mainly silymarin flavonolignans and flavonoids, that may be considered as putative biomarkers of authenticity. All formulations contained molecules from silymarin complexes at different levels. The quantitative evaluation of silybins was done using in parallel UV spectrometry and UHPLC-QTOF-ESI+MS and their correlations were compared. DNA metabarcoding detected milk thistle in eleven out of sixteen retained preparations, whereas two others had incomplete evidence of milk thistle despite metabolomics validating specific metabolites, e.g., silymarin complex, identified and quantified in all samples. Meanwhile, the DNA metabarcoding provided insights into the total species composition allowing the interpretation of the results in a broad context.ConclusionOur study emphasizes that combining spectroscopic, chromatographic, and genetic techniques bring complementary information to guarantee the quality of the botanical formulations.

Athletes Perceived Level of Risk Associated with Botanical Food Supplement Use and Their Sources of Information.

Athletes should carefully consider the use of botanical food supplements (BFSs) given the current lack of substantiation for botanical nutrition and health claims under EU and UK food laws. In addition, athletes may be at an increased risk of doping violations and other adverse outcomes potentially associated with BFS use; however, little is known about athletes' intake, knowledge, or perceptions in relation to BFS use. An online cross-sectional survey of n = 217 elite and amateur athletes living on the island of Ireland was conducted using Qualtrics XM to assess intake, knowledge, attitudes, and perceptions. General food supplements (FSs) were reported by approximately 60% of the study cohort, and 16% of the supplements reported were categorized as BFS. The most frequently consumed BFSs were turmeric/curcumin (14%), Ashwagandha (10%), and Beetroot extract (8%). A higher proportion of amateur athletes would source information about BFSs from less credible sources, such as fellow athletes, or from internet sources or their coach, compared to elite athletes. Those who sourced information about botanicals from fellow athletes (p = 0.03) or the internet (p = 0.02) reported a lower perceived level of risks associated with BFS use. This study therefore suggests that amateur athletes may be more likely to source information from less credible sources compared to elite athletes who may have more access to nutrition professionals and their knowledge/advice. This may have potential adverse implications for amateur athletes, e.g., Gaelic games players, who are included within the doping testing pool but who may not have access to evidence-based nutrition advice.
