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.

Prediction of physicochemical and pharmacokinetic properties of botanical constituents by computational models.

Botanicals contain complex mixtures of chemicals most of which lack pharmacokinetic data in humans. Since physicochemical and pharmacokinetic properties dictate the in vivo exposure of botanical constituents, these parameters greatly impact the pharmacological and toxicological effects of botanicals in consumer products. This study sought to use computational (i.e., in silico) models, including quantitative structure-activity relationships (QSAR) and physiologically based pharmacokinetic (PBPK) modeling, to predict properties of botanical constituents. One hundred and three major constituents (e.g., withanolides, mitragynine, and yohimbine) in 13 botanicals (e.g., ashwagandha, kratom, and yohimbe) were investigated. The predicted properties included biopharmaceutical classification system (BCS) classes based on aqueous solubility and permeability, oral absorption, liver microsomal clearance, oral bioavailability, and others. Over half of these constituents fell into BCS classes I and II at dose levels no greater than 100 mg per day, indicating high permeability and absorption (%Fa > 75%) in the gastrointestinal tract. However, some constituents such as glycosides in ashwagandha and Asian ginseng showed low bioavailability after oral administration due to poor absorption (BCS classes III and IV, %Fa < 40%). These in silico results fill data gaps for botanical constituents and could guide future safety studies. For example, the predicted human plasma concentrations may help select concentrations for in vitro toxicity testing. Additionally, the in silico data could be used in tiered or batteries of assays to assess the safety of botanical products. For example, highly absorbed botanical constituents indicate potential high exposure in the body, which could lead to toxic effects.

Biological Activities and Polyphenol Content of Qi Cha Tea®, a Functional Beverage of White Tea Containing Botanicals and Dry Botanical Extracts with European Health Claims.

Infusions of Camellia sinensis leaves have been known for their health benefits. The Bio Concentrate Assets® (ABC) method is a method of enriching organic infusion leaves (from Camellia sinensis) with organic dry and concentrated extracts using organic acacia gum, and its application to white tea has provided Qi cha tea®. In the present study, the content of tea polyphenols and caffeine, and the biochemical properties of Qi cha tea® and its botanical constituents (elderberry, tulsi, Echinacea purpurea, orange peel, lemongrass, and acacia gum) were assessed. Antioxidant and cell viability activities were determined by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay and MTT (3-(4, 5-dimethyl thiazol-2-yl)-2, 5-diphenyl tetrazolium bromide) assay in human Caco-2 and HCT-116 cell lines, and ascorbic acid and tamoxifen, respectively. The caffeine and polyphenol composition of Qi cha tea® was modified with less caffeine and gallic acid and more epigallocatechin gallate (EGCG) than the original white tea. The majority of the tested botanical samples including Qi cha tea® at 50 µg/mL show similar antioxidant activities, with the exception of Echinacea purpurea. The greatest effect was found for white tea. The antioxidant power of the Qi cha tea® (90% at 50 µg/mL for pressurized liquid extraction (PLE) was divided by approximately a factor of two (61% at 50 µg/mL for pressurized liquid extraction products (PLEP)), which corresponds to the 48.3% (mass/mass) white tea original content in the Qi cha tea®. Qi cha tea® shows the lowest cytotoxic activity in the viability of the two cell lines when compared to white tea. The application of the ABC method to Qi cha tea® using various botanicals and dry extract with acacia gum as blinder has allowed the development of a new innovative functional health beverage that complies with European health claims.

Understanding of black salve toxicity by multi-compound cytotoxicity assays

BackgroundBlack salve is a controversial complementary and alternative medicine (CAM) associated with skin toxicity and skin cancer treatment failures. Black salve formulations vary between manufacturers and contain a number of botanical and synthetic constituents. The skin cancer cytotoxicity of a number of these constituents has not been assessed to date. The alkaloids from the rhizomes of Sanguinaria canadensis, a key black salve ingredient, have had their single compound cytotoxicity assessed; however, whether they possess synergistic cytotoxicity with other compounds has not been studied and is of direct clinical relevance. This research aimed to improve our understanding of the skin cancer cytotoxicity of black salve constituents.MethodsThe cytotoxicity of individual and combination black salve constituents were assessed against the A375 melanoma and A431 squamous cell carcinoma cell lines. Cytotoxicity was determined using the Resazurin assay with fluorescence measured using a Tecan Infinite 200 Pro Microplate reader, compound cytotoxicity being compared to that of the topical cancer therapeutic agent, 5- fluouracil. Docetaxal was used as a positive control. Dunnetts p value was used to determine whether significant synergistic cytotoxicity was present.ResultsSanguinarine was the most cytotoxic compound tested with a 24-hour IC50 of 2.1 μM against the A375 Melanoma cell line and 3.14 μM against the A431 SCC cell line. All black salve constituents showed greater cytotoxicity against the two skin cancer cell lines tested than the skin cancer therapeutic 5-Fluouracil with 24 hours of compound exposure. Chelerythrine and minor Quaternary Benzophenanthridine Alkaloids (QBAs) present in black salve, at concentrations not having a cytotoxic effect by themselves, boosted the cytotoxic effects of sanguinarine. This could be a synergistic rather than additive cytotoxic effect although the synergistic effect was cell line and concentration dependent.ConclusionsBlack salve contains several cytotoxic compounds, a number of which have been found to possess synergistic cytotoxicity for the first time against skin cancer cell lines. In addition, these compounds together increase the overall cytotoxic effect. Assessing multi-compound cytotoxicity in herbal medicine can provide additional information about both their therapeutic and toxicity potential. As black salve is currently being used by patients, further cytotoxicity work should be undertaken to assess whether synergistic cytotoxicity exists when tested in normal skin cells.

Use of Botanical Pesticides in Agriculture as an Alternative to Synthetic Pesticides

Pest management is being confronted with immense economic and environmental issues worldwide because of massive utilization and over-reliance on pesticides. The non-target toxicity, residual consequence, and challenging biodegradability of these synthetic pesticides have become a serious concern, which urgently requires the alternative and prompt adoption of sustainable and cost-effective pest control measures. Increasing attention in environmental safety has triggered interest in pest control approaches through eco-friendly plant-based pesticides. Botanical pesticidal constituents are effective against myriads of destructive pests and diseases. More importantly, they are widely available, inexpensive, accessible, rapidly biodegradable, and have little toxicity to beneficiary agents. The phytochemical compositions in diverse plant species are responsible for their varying mechanisms of action against pests and diseases. However, difficulties in their formulation and insufficient appropriate chemical data have led to a low level of acceptance and adoption globally. Therefore, the review seeks to highlight the status, phytochemical compositions, insecticidal mechanisms, and challenges of plant-based pesticide usage in sustainable agricultural production.

Development and optimization of Benjakul microemulsion formulations for enhancing topical anti-inflammatory effect and delivery.

Background and purpose:Benjakul (BJK) is a combination of five botanical herbal constituents widely used in Thai traditional medicine as an anti-inflammatory remedy. This study aimed to develop a novel topical microemulsion containing BJK for clinical use.Experimental approach:The microemulsions were produced by a phase inversion temperature (PIT) methodology. Physicochemical properties and stability were evaluated to determine an optimal formula. The stable BJK-loaded microemulsion formulas were then subjected to in vitro studies for their anti-inflammatory activity, skin cell toxicity, drug permeation, and stability.Finding/Results:Two novel formulations containing isopropyl myristate (ME1-BJK and ME2-BJK) passed the compendial stability test. BJK constituents were completely dissolved in the oil phase and incorporated into the microemulsion base Transcutol® and Labrasol® avoiding the use of alcohol, both microemulsion formulations demonstrated high anti-inflammatory activity with IC50 values of 3.41 ± 0.36 and 3.95 ± 1.73 μg/mL, respectively. However, dissolution of ME1-BJK showed a superior release profile through both lipophilic and hydrophilic membranes with the highest accumulated amount at 4 h of 25.13% and 38.06%, respectively. All tested formulations of BJK extract demonstrated no apparent skin cell toxicity at concentrations up to 50 μg/mL. After six-month storage under accelerated conditions, there were no significant changes in anti-inflammatory activity.Conclusions and implications:A novel and stable BJK-loaded microemulsion formulation was successfully developed with excellent release and stability properties. Further clinical research to evaluate pain reduction, edema, and skin irritation using this formulation in animal models is ongoing.

Aspects of pharmacognostic evaluation of the herbs for a traditional antimalarial (maloff-hb) powdered formulation in ogbomoso, Nigeria

Maloff-HB is a documented traditional oral powdered herbal drug in Ogbomoso, Nigeria whose botanical constituents, ascorbic acid and mineral elements composition have been quantified but there is inadequate information on the pharmacognostic properties of the nine herbal materials for its formulation. This study therefore sought to elucidate the bark and wood anatomy of eight of the nine herbs used in the formulation, and identify the diagnostic markers for their authentication. The conventional anatomical techniques of transverse sectioning (TS) and tissue maceration (TIM) were used to draw out 21 characteristics from the root barks of the eight woody species studied. In addition, 41 features of the wood in the roots of three of the species were drawn using TS, transverse longitudinal sectioning (TLS), radial longitudinal sectioning (RLS) and TIM. Following staining, mounting and microscopic examinations, the observed qualitative and quantitative features were taxonomically described in accordance with the provisions of International Association of Wood Anatomists, and their diagnostic values among the medicinal herbs were explored. Bark anatomical markers that are clearly diagnostic of the species studied included features of the secondary cortex, phloem rays, axial parenchyma, sclereids and resin ducts. In the wood, these included features of the vessels in the TS and variable ray characteristics in the TLS. The two artificial keys obtained from discontinuities in qualitative and quantitative features observed in the barks and the woods are useful tools for reliable identification of the herbal materials studied.

Evaluation of some pharmacognostic parameters of the herbs for a traditional hematinic (Haematol -B) powdered formulation in Ogbomoso, Nigeria

The traditional hematinic oral powdered herbal drug (Haematol-B) from Ogbomoso, Nigeria had been characterized in terms of its botanical constituents, ascorbic acid and mineral elements composition, but there is inadequate information on the pharmacognostic properties of the ten herbal materials for its formulation. Therefore the objective of this study was to evaluatethe bark and wood anatomy (as appropriate) of seven of these herbs with a view to highlighting the diagnostic markers for their authentication. Following the conventional anatomical procedures of transverse sectioning (TS) and tissue maceration (TIM), a total of 21 characters were drawn from the barks (root or stem as appropriate) of the seven woody species studied, while 41 characteristics of the wood in the roots of three of the species were compiled using TS, transverse longitudinal sectioning (TLS), radial longitudinal sectioning (RLS) and TIM techniques. Staining, mounting and microscopic examinations followed, and the observed features were taxonomically described in accordance with the provisions of International Association of Wood Anatomists. Their diagnostic values among the medicinal herbs studied were also explored. The bark anatomical features that can be used to diagnose the species studied were those of the secondary cortex, phloem rays, axial parenchyma, sclereids and resin ducts. The wood anatomical markers included features of the vessels in the TS and variable ray characteristics in the TLS. The two artificial keys constructed from discontinuities in qualitative and quantitative anatomical features of the barks and the wood are useful tools for avoiding misidentification of the herbal materials studied.

Herbal Recipes, Drug Indications and Sustainability Potential of Traditional Oral Liquid Formulations in Ogbomoso, Nigeria

Confirmation of identity, along with determination of the quality and purity of herbal drug is an important step towards ensuring its safety and efficacy. This study therefore sought to document the botanical constituents and drug indications of traditional oral liquid herbal formulations (TOLHFs) manufactured in Ogbomoso, Nigeria. It also examined the conservation status of the medicinal plants so used alongside the cultivation efforts being made by the drug manufacturers in order to provide information on whether continual exploitation of the plants for TOLHFs is sustainable. Through a questionnaire, 14 traditional herbal medical practitioners (THMPs)provided information on the recipes of their products, the sources of their raw material herbs, and types of health conditions treated or managed with the drugs. Sustainability potential of the drugs was quantified as relative percentage of the three choices of sources of raw material herbs available to the manufacturers in conjunction with the conservation status of the plant species as recorded by the International Union for Conservation of Nature (IUCN).Fifty-seven medicinal plant species (in 34 angiosperm families) were used to formulate 71 herbal recipes that are indicated for treating 14 different health conditions.

Curcuma Longa, the "Golden Spice" to Counteract Neuroinflammaging and Cognitive Decline-What Have We Learned and What Needs to Be Done.

Due to the global increase in lifespan, the proportion of people showing cognitive impairment is expected to grow exponentially. As target-specific drugs capable of tackling dementia are lagging behind, the focus of preclinical and clinical research has recently shifted towards natural products. Curcumin, one of the best investigated botanical constituents in the biomedical literature, has been receiving increased interest due to its unique molecular structure, which targets inflammatory and antioxidant pathways. These pathways have been shown to be critical for neurodegenerative disorders such as Alzheimer’s disease and more in general for cognitive decline. Despite the substantial preclinical literature on the potential biomedical effects of curcumin, its relatively low bioavailability, poor water solubility and rapid metabolism/excretion have hampered clinical trials, resulting in mixed and inconclusive findings. In this review, we highlight current knowledge on the potential effects of this natural compound on cognition. Furthermore, we focus on new strategies to overcome current limitations in its use and improve its efficacy, with attention also on gender-driven differences.

Antifeedant and ovicidal activities of a new cassane and other compounds from Caesalpinia welwitschiana Oliv. and Caesalpinia bonduc L. against Tuta absoluta (Lepidoptera: Gelechiidae)

Methanolic extracts of liana of Caesalpinia welwitschiana and leaves of C. bonduc were found to possess moderate antifeedant and ovicidal activities against Tuta absoluta. Bioassay-guided isolation of constituents from the most active fraction of C. welwitschiana led to the identification of four known compounds [isobonducellin 1a and bonducellin 1 b, intricatinol 2, (-)-epigallocatechin-3-O-gallate 4] and one new constituent [welwitschianic acid 3]. The most active fraction of C. bonduc afforded two known constituents neocaesalpin L 5 and neocaesalpin A 6. The isolated structures were elucidated on the basis of their MS, UV, IR and 1 & 2 D NMR spectra and by comparison with literature data. Compounds 2, 4-6 were showed antifeedant and ovicidal properties against T. absoluta, some comparable to that of azadirachtin at 50, 100 and 200 ng/µl. Overall, the present study, conclude that the two species of the plant could be a promising source of eco-friendly botanical constituents.

Neochamaejasmin A Induces Mitochondrial-Mediated Apoptosis in Human Hepatoma Cells via ROS-Dependent Activation of the ERK1/2/JNK Signaling Pathway.

The botanical constituents of Stellera chamaejasme Linn. exhibit various pharmacological and medicinal activities. Neochamaejasmin A (NCA), one main active constituent of S. chamaejasme, inhibits cell proliferation and induces cell apoptosis in several types of tumor cells. However, the antitumor effect of NCA on hepatocellular carcinoma cells is still unclear. In this study, NCA (36.9, 73.7, and 147.5 μM) significantly inhibited hepatoblastoma-derived HepG2 cell proliferation in a concentration-dependent manner. Hoechst 33258 staining and flow cytometry showed that apoptotic morphological changes were observed and the apoptotic rate was significantly increased in NCA-treated HepG2 cells, respectively. Additionally, the levels of Bax, cleaved caspase-3, and cytoplasmic cytochrome c were increased, while the level of Bcl-2 was decreased in NCA-treated HepG2 cells when compared with the control group. Moreover, we found that the reactive oxygen species (ROS) level was significantly higher and the mitochondrial membrane potential was remarkably lower in NCA-treated HepG2 cells than in the control group. Further studies demonstrated that the levels of p-JNK and p-ERK1/2 were significantly upregulated in NCA-treated HepG2 cells, and pretreatment with JNK and ERK1/2 inhibitors, SP600125 and PD0325901, respectively, suppressed NCA-induced cell apoptosis of HepG2 cells. In addition, NCA also significantly inhibited human hepatoma BEL-7402 cell proliferation and induced cell apoptosis through the ROS-mediated mitochondrial apoptotic pathway. These results implied that NCA induced mitochondrial-mediated cell apoptosis via ROS-dependent activation of the ERK1/2/JNK signaling pathway in HepG2 cells.

Farmers who forage: interpreting paleofecal evidence of wild resource use by early corn farmers in the North American Southwest

This paper describes and interprets the results of multiple analyses conducted on human paleofeces from Turkey Pen Ruin, an early Ancestral Pueblo farming site in Cedar Mesa, Utah. Analyses of pollen and macroscopic contents were performed on 44 specimens; DNA testing for several faunal and botanical dietary constituents was also conducted on select samples (n = 20) using targeted PCR analysis. These data were used to assess what foods supplemented the predominant dietary staple—maize (Zea mays). Resources were evaluated based on caloric efficiency and nutritional value to gain insight into what motivated these late Basketmaker II period (ca. AD 1-400) farmers to continuously rely so heavily on corn, in lieu of incorporating a higher proportion of foraged resources into their diet. This project confirms a very high level of maize reliance (likely around 80% of the diet) as established by earlier studies. However, these results also show common inclusion of wild resources that are much less calorically efficient than the type of maize farming practiced here, including weedy plants commonly associated with agricultural fields. This suggests early farmers on Cedar Mesa were pushed by low environmental productivity to rely on farming, and to include low-ranked wild resources to calorically and nutritionally augment their maize-based diet. These findings also indicate that farmers were harvesting much more than corn from their fields, and that the productivity of the anthropogenic ecological niche created by farming activities may have influenced supplemental foraging choices, as well as the degree of labor dedicated to fields.

Botanical characterisation, drug indications and sustainability status of traditional oral powdered herbal formulations in Ogbomoso, Nigeria

Background: The foremost requirements in quality control of a herbal drug are its identity and purity. In addition, information is necessary on whether continual exploitation of medicinal herbs for traditional oral powdered herbal formulations (TOPHFs) in Ogbomoso, Nigeria, is sustainable. Aim: To botanically characterise and ethno-medicinally document the health indications of TOPHFs manufactured in Ogbomoso, as well as to examine the sustainability status of the drugs. Setting: Ogbomoso, Nigeria. Methods: Fifteen manufacturers of TOPHFs provided information on the botanical constituents and recipes of their products, the sources of raw material herbs, and types of health conditions treated with the drugs. Sustainability status of the drugs was quantified as relative percentage of the three choices of sources of raw material herbs available to the manufacturers and in terms of conservation status of the plant species as recorded by the International Union for Conservation of Nature. Results: Fifty-five medicinal plant species from 33 angiosperm families were used by traditional herbal medical practitioners to produce 68 TOPHFs that are indicated for treating 17 different health conditions. The sources of raw material herbs, in relative terms, were purchased from herbal markets (43.8%), collected from the wild (28.1%) and cultivated (28.1%). Most of the herbs can be sustainably harvested and only 3 (i.e. 5.5%) of the 55 plant species (i.e. Lophira alata Banks ex Gaertn., Khaya senegalensis A. Juss. and Garcinia kola Heckel) are under threatened (vulnerable) species. Conclusion: Production of TOPHFs in Ogbomoso is sustainable with minimal injury on the natural flora.

A multi-detector chromatographic approach for characterization and quantitation of botanical constituents to enable in silico safety assessments

An approach has been developed to characterize the individual chemical constituents of botanicals. The challenge was to identify and quantitate the significant analytes in these complex mixtures, largely in the absence of authentic standards. The data-rich information content generated by this three-detector configuration was specifically intended to be used to conduct safety and/or quality evaluations for complex botanical mixtures, on a chemical constituent basis. The approach utilized a broad gradient UHPLC chromatographic separation. Following the chromatographic separation and UV detection, the eluent was split and sent into a charged aerosol detector (CAD), for quantitation, and a quadrupole/time-of-flight high-resolution mass spectrometer for component identification. The known bias of the otherwise universal CAD response, for organic solvent composition of the mobile phase, was compensated by the addition of an inverse gradient make-up stream. This approach and the orthogonal information content from the chromatography and three different detectors was specifically designed to enable in-silico safety assessments. These guide, minimize, or even eliminate the need for in vivo and in vitro safety assessments. The methodology was developed and demonstrated using standardized extracts of Ginkgo biloba. Results from the development of this novel approach and the characterization example reported here demonstrate the suitability of this instrumental configuration for enabling in-silico safety assessments and proving general quality assessments of botanicals.
