Neng-Jing-Huo Essential Oil Blend Inhibits Lipopolysaccharide-Induced Intracellular Reactive Oxygen Species Accumulation, Inflammation, and Apoptosis in Renal Tubular Epithelial Cells.

Acute kidney injury (AKI) is a common serious complication of sepsis that is characterized by the rapid deterioration of kidney function. Neng-Jing-Huo (NJH) is an essential oil blend, including Gaultheria procumbens, Zingiber officinale, Bulnesia sarmientoi, Artemisia vulgaris, and Styrax benzoin oils, with antimicrobial, antioxidant, and anti-inflammatory activities. Here, we investigated the effects of NJH on oxidative stress, inflammatory response, and apoptosis in an in vitro septic AKI model and explored the underlying mechanisms. A cellular model of septic AKI was established using lipopolysaccharide (LPS). Cell viability was assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Action mechanisms of NJH were analyzed using the Griess reagent, 2',7'-dichlorodihydrofluorescein diacetate, 5,5',6,6' tetrachloro-1,1'3,3' tetraethylbenzimidazolcarbocyanine iodide, annexin V, caspase activity, western blotting, and semi-quantitative reverse transcription polymerase chain reaction assays. Results showed that pretreatment with NJH significantly improved cell survival and suppressed nitric oxide (NO) production in LPS-stimulated NRK-52E renal tubular epithelial cells. NJH also decreased the levels of intracellular reactive oxygen species and maintained the mitochondrial membrane potential by upregulating the nuclear factor (NF) erythroid 2-related factor 2/heme oxygenase-1 levels and downregulating the NADPH oxidase 4 levels. In addition, NJH suppressed the activation of the toll-like receptor 4/NF-κB and NLRP3/caspase-1 pathways, thereby decreasing the inflammatory response in LPS-stimulated NRK-52E cells. Moreover, NJH decreased the levels of Bax, caspase-9, and caspase-3 but increased those of Bcl-2, which led to a reduction in LPS-induced apoptosis. Overall, our findings revealed that NJH ameliorated LPS-induced damage in NRK-52E cells by inhibiting oxidative stress, inflammation, and apoptosis, highlighting its therapeutic potential for septic AKI.

Differential Enhancement of Fat-Soluble Vitamin Absorption and Bioefficacy via Micellization in Combination with Selected Plant Extracts In Vitro.

Background/Objectives: Individuals with special metabolic demands are at risk of deficiencies in fat-soluble vitamins, which can be counteracted via supplementation. Here, we tested the ability of micellization alone or in combination with selected natural plant extracts to increase the intestinal absorption and bioefficacy of fat-soluble vitamins. Methods: Micellated and nonmicellated vitamins D3 (cholecalciferol), D2 (ergocalciferol), E (alpha tocopheryl acetate), and K2 (menaquionone-7) were tested in intestinal Caco-2 or buccal TR146 cells in combination with curcuma (Curcuma longa), black pepper (Piper nigrum), or ginger (Zingiber officinale Roscoe) plant extracts. The vitamin uptake was quantified via HPLC-MS, and bioefficacy was assessed via gene expression analyses or the Griess assay for nitric oxide generation. Results: Micellization increased the uptake of vitamin D into buccal and intestinal cells, with vitamin D3 being more efficient than vitamin D2 in increasing the expression of genes involved in calcium transport. The micellization of vitamin E acetate increased its uptake and conversion into biologically active free vitamin E in intestinal cells only. The vitamin K2 uptake into buccal and intestinal cells was increased via micellization. Plant extracts increased the uptake of select micellated vitamins, with no plant extract being effective in combination with all vitamins. The curcuma extract increased the uptake of vitamins D2/D3 but not their bioefficacy. Black pepper and ginger extracts increased the uptake of vitamin E acetate into intestinal cells but failed to increase its conversion into free vitamin E. The ginger extract augmented the uptake of vitamin K2 and increased NO generation additively. Conclusions: Our data substantiate the positive effects of micellization on fat-soluble vitamin absorption and bioefficacy in vitro. While the application of plant extracts in addition to micellization to further increase bioefficacy is an interesting approach, further studies are warranted to understand vitamin-specific interactions and translation into increased bioefficacy.

Selected Use of Complementary and Alternative Medicine (CAM) Agents in IBD.

Inflammatory bowel disease (IBD) can cause significant psychological, physical, and economic burdens on patients and healthcare systems. Studies show over one-fifth of patients will seek nontraditional methods of treatment for managing their symptoms. Understanding the benefits - and potential harms - of these therapies is important to provide holistic and evidence-based care to our IBD patients. In this review, we present several studied herbal therapies for the management of both Crohn's disease and ulcerative colitis. These include cannabinoids, Tripterygium wilfordii, Chios mastic gum, Boswellia serrata, Indigo Naturalis, curcumin, resveratrol, and Zingiber officinale. While these herbal remedies have been shown to have anti-inflammatory effects and positive outcomes in IBD patients, larger scale studies are lacking and the use may be limited by bioavailability, lack of standardization of formulations, and adverse reactions. In reviewing the literature, we discuss the current data available including benefits, adverse reactions, and considerations for use surrounding several of the more common herbal remedies used for IBD.

Very-Low-Absorbable Geraniol for the Treatment of Irritable Bowel Syndrome: A "Real-World" Open-Label Study on 1585 Patients.

The objective of this study was to evaluate the efficacy of a very-low-absorbable geraniol formulation, administered as a food supplement, in patients with irritable bowel syndrome (IBS) in a real-world setting in Italy. This open-label study was conducted in Italy on patients diagnosed with IBS and treated for 4 weeks with 240 mg/day of Palmarosa essential oil, absorbed on 960 mg of ginger root powder to obtain a very-low-absorbable geraniol formulation. Baseline characteristics, including demographic and symptoms were recorded using the IBS Severity Scoring System (IBS-SSS). After 28 ± 7 days, the patients were asked to complete the IBS-SSS questionnaire again. The primary objective was to confirm the effects of a very-low-absorbable geraniol formulation on self-reported symptoms of IBS and the quality of life of affected individuals. The secondary objective was to confirm the effect of the treatment on the different IBS subtypes. A total of 1585 patients were included in the study, with a mean age of 44.8 years and 56.4% women. Following the 4-week supplementation period, significant decreases were observed in the patients' IBS-SSS (-67.9%) and all the primary IBS symptoms, such as abdominal distention (-82.3%), unsatisfaction with bowel habits (-46.2%), and interference with quality of life (QoL) (-64.9%) (all p < 0.01). The patients' stool type improved significantly. Treatment was effective in all IBS subtypes. Treatment with very-low-adsorbable geraniol food supplement was associated with improvements in symptoms and bowel habits in all IBS subtypes in a real-world setting in Italy. These findings support the use of geraniol as an effective option for patients with IBS regardless of the disease subtype.

First Report of Bacterial Wilt of Ginger Caused by Ralstonia pseudosolanacearum in the Continental United States.

Ginger (Zingiber officinale) is an herbaceous perennial in the Zingiberaceae family grown primarily in tropical to subtropical biomes as a culinary spice, a traditional medicine, and a landscaping plant. While ginger grows at soil temperatures above 20°C, several farmers in the upper Midwestern US farmers grows short-season ginger in high tunnels. In 2023 and 2024, growers in southeastern Minnesota reported a new disease of ginger. USDA traced the origin of the ginger rhizomes imported by these growers to Peru (Soto-Heredia et al., 2024). Plants exhibited wilting, chlorosis, pseudostem collapse, and plant death. Rhizomes were squishy with a fetid, rotting odor. Disease incidence ranged from scattered plants to 50% of the crop. Symptomatic samples tested positive for Ralstonia solanacearum species complex (RSSC) using AgDia ImmunoStrips. Rhizome tissue extracts plated onto CPG + 1% tetrazolium chloride agar and mSMSA agar produced irregular, round-to-fluidal white colonies with pink centers after 48 h of incubation at 28°C (Kelman 1954; Engelbrecht 1994). Diagnostic RSSC phylotype-specific multiplex PCR primers Nmult21:1F, Nmult21:2F, Nmult23:AF, Nmult22:InF, Nmult22:RR, and 759f/760r confirmed isolate identity; two isolates (UMN24-1, UMN24-2) yielded bands at 280 bp and 144 bp, identifying them as RSSC and phylotype I respectively (Fegan and Prior 2005; Opina et al. 1997). Additionally, 16S rRNA PCR of these isolates was sequenced using primers 27F (5'-AGAGTTTGATCMTGGCTCAG-3')/1492R (5'-TACGGYTACCTTGTTACGACTT-3') and shared >99% identity (isolate UMN24-1: 99.00% 27F, 99.53% 1492R; UMN24-2: 99.32% 1492R) with R. pseudosolanacearum (Rps) strain Gj707 (GenBank CP104497.1). Eight ginger plants in individual pots were grown in a Conviron growth chamber (28°C, 250 μmol/m2/s, 16 h photoperiod) and inoculated at the six-leaf stage (6 weeks old) by pipetting 109 CFU of the isolate, UMN24-1, suspended in sterile water into a 30°angled 1 cm incision on the pseudostem. We scored disease incidence based on wilted leaves per total leaves on each plant for 14 days post inoculation (dpi). While control plants remained healthy, inoculated plants showed symptoms (wilting, vascular discoloration, chlorosis) at 4 dpi, were 100% wilted by 6 dpi, and all pseudostems completely collapsed by 11 dpi (Fig. S1). Bacteria recovered from the inoculated plants matched the original isolate in appearance and positively identified as RSSC phylotype I using the PCR analyses described above. To confirm taxonomic identification of UMN24-1, the complete genome of this isolate was sequenced using hybrid Illumina and Oxford Nanopore sequencing (NCBI BioProject ID PRJNA1178296, release date upon publication) (Fig. S2). Average nucleotide identity (ANI) analysis of UMN24-1 using KBase's FastANI app reported 99.8% identity shared with Japanese RSSC phylotype I strain MAFF311693 (GenBank GCF 015698385.1). We also sequenced UMN24-2, and its phylogenetic analysis revealed that the two isolates are clonal (Fig. S2). Hence, we did not submit its sequence to the NCBI. This marks the first documented case of Rps in ginger in the United States. Similar to bacterial wilt in ginger closely related crop like turmeric has been repeatedly reported in northern Europe in recent years (EPPO 2024). While RSSC phylotype I is geographically limited by its minimal cold tolerance, the emergence of a pathogen with a potentially broad host range has worrying implications in a changing climate.

Mechanistic insight into neuroprotective effect of standardized ginger chemo varieties from Manipur, India in scopolamine induced learning and memory impaired mice.

Alzheimer's disease is a complex neurodegenerative disease characterized by progressive decline in cognitive function and behaviour. Ginger is the rhizome of the plant Zingiber officinale Roscoe, has been an important ingredient of many Ayurveda formulations to treat neurological disorders. The present study aims to estimate the variation of 6-gingerol content in nine different ginger samples collected from Manipur, India, investigate the neuroprotective potential of the most potent ginger sample against scopolamine-induced cognitively impaired mice, and validate the therapeutic claim by molecular docking analysis. High Performance Thin Layer Chromatography (HPTLC) analysis suggested that the sample GV6 had the highest 6-gingerol content with potent in vitro acetylcholnesterase (AChE) (IC50 = 336.10µg/mL) and butyrylcholinesterase (BChE) (IC50 = 411.73µg/mL) enzyme inhibitory activity. The neuroprotective potential of GV6 was tested in scopolamine-induced cognitively impaired mice (200 and 400mg/kg). The behavioral analysis showed that GV6 alleviated the spatial recognition, and short-term and long-term memory in the experimental mice model. GV6 significantly improved brain AChE and BChE activity, acetylcholine (ACh) level, markedly alleviated the antioxidant parameters, and reversed the neuroinflammation. Brain histopathological observations confirmed the presence of organized nerve fibers, improvement of neuronal cell density, and reverse the nucleus shrinkage. Further molecular docking analysis showed that 6-gingerol and galantamine exhibited stable interaction with AChE (-7.5 and - 7.3 kcaL/moL) and BChE (-7.3 and - 8.5 kcaL/moL). The present study emphasizes the quality-related therapeutic importance of ginger samples from Northeast India and demonstrates that administration of GV6 may improve brain cognitive functions by restoring neurotransmitter levels and inflammatory and antioxidant parameters in scopolamine-induced cognitively impaired mice.

Zahabba Patch: Innovation of Gingival Mucoadhesion Patch Combination of Ginger (Zingiber Officinale) and Black Cubit (Nigella Sativa) as Gingivitis Treatment

Background The prevalence of periodontal disease in Indonesia reaches 74.1%. Treatment of gingivitis by administering NSAIDs has a side effect of gastritis. Anti-inflammatory and analgesic derived from natural ingredients are known to cause minimal side effects on the patient's body. The active compounds gingerol in ginger (Zingiber officinale) and quercetin in black cumin (Nigella sativa) are known to function as good anti-inflammatory and analgesic agents. Objectives This study aims to analyze the effectiveness of gingerol in ginger extract and qurcetin in black cumin as an anti-inflammatory and analgesic packaged in a mucoadhesion patch as a treatment for gingivitis. Material and Methods Preparations of gingerol and quercetin were obtained by biocomputation using the PyRx program, the Pymol program, the RCSB PDB website, the Lipinski rule of five page, the PDBSum website, and also the pkCSM website. Physicochemical, pharmacokinetic, toxicity, and molecular docking tests were carried out to determine the biocompatibility of the active ingredients used. Results In the physicochemical tests, the compounds glycerol and quercetin can penetrate somatic cell membranes, have good solubility in water, can dissolve easily in the blood, are easily distributed in the body, and can maintain their position and bond strength with the target macro protein. The results of the AMES toxicity, Hepatotoxicity and skin sensitization tests showed negative values for both gingerol and quercetin. In the molecular docking test, the gingerol and quercetin compounds have a tendency to form bonds with COX-1 compared to arachidonic acid without having to increase the dose so that they become competitors to the native ligand. Conclusion The active compounds gingerol in ginger extract (Zingiber officinale) and quercetin in black cumin extract (Nigella sativa) contained in Zahabba patch are good anti-inflammatory and analgesic by inhibiting the synthesis of pro-inflammatory cytokines such as PGI2, PGE2, and TXA2 by being competitive inhibitor of the enzyme phospholipase A2 against membrane lipids and the enzyme cyclooxygenase-1 (COX-1) against arachidonic acid.

A Review on the Potential of Ginger Essential Oil-based Nanotechnology for Controlling Tropical Plant Diseases

The increasing prevalence of plant diseases in tropical agriculture, driven by climate change, pathogen resistance, and unsustainable pesticide use, necessitates the development of eco-friendly and effective disease management strategies. Ginger essential oil (GEO), derived from Zingiber officinale, is a natural antimicrobial agent with proven efficacy against a wide range of plant pathogens, including bacteria, fungi, and viruses. Its bioactive compounds, such as gingerols, shogaols, and zingiberene, exhibit multiple modes of action, making GEO a promising alternative to synthetic pesticides. Its volatility, short shelf life, and limited solubility under field conditions restrict its direct application in agriculture. Nanotechnology offers a transformative solution to these limitations by encapsulating GEO in advanced nanocarriers, such as liposomes, nanoemulsions, and polymeric nanoparticles, which improve its stability, bioavailability, and controlled release. Nanoformulated GEO has demonstrated enhanced antimicrobial efficacy in both laboratory and field studies, outperforming pure GEO and synthetic agrochemicals in controlling plant pathogens like Fusarium oxysporum, Alternaria alternata, and Xanthomonas campestris. GEO nanoformulations are biodegradable and pose minimal risks to non-target organisms and the environment, aligning with the principles of sustainable agriculture. Despite these promising outcomes, challenges such as high production costs, regulatory uncertainties, and limited farmer awareness hinder the large-scale implementation of GEO nanotechnology. It should focus on optimizing nanoformulation techniques, exploring synergistic combinations with other natural antimicrobials, and integrating GEO nanoformulations into integrated pest management (IPM) strategies. Collaboration between researchers, policymakers, and farmers is essential to overcome adoption barriers and ensure effective deployment. By addressing these challenges, GEO-based nanotechnology has the potential to revolutionize tropical agriculture, providing a sustainable, safe, and innovative solution for managing plant diseases while reducing dependency on harmful chemical pesticides.

Green Tea Extract (Theaceae; Camellia sinensis L.): A Promising Antimicrobial, Anti-Quorum Sensing and Antibiofilm Candidate Against Multidrug-Resistant Campylobacter Species.

Thermophilic Campylobacter species are among the main culprits behind bacterial gastroenteritis globally and have grown progressively resistant to clinically important antimicrobials. Many studies have been carried out to explore innovative and alternative strategies to control antibiotic-resistant campylobacters in animal reservoirs and human hosts; however, limited studies have been performed to develop efficient control schemes against Campylobacter biofilms. This study investigated the antimicrobial and antibiofilm activities of some herbal extracts against multidrug-resistant (MDR) Campylobacter species recovered from different sources using phenotypic and molecular techniques. The overall Campylobacter species prevalence was 21.5%, representing 15.25% and 6.25% for C. jejuni and C. coli, respectively. Regarding C. jejuni, the highest resistance rate was observed for amoxicillin-clavulanic acid and colistin (85.25% each), followed by cefotaxime (83.61%) and tetracycline (81.97%), whereas C. coli isolates showed absolute resistance to cefotaxime followed by erythromycin (92%) and colistin (88%). Remarkably, all Campylobacter isolates were MDR with elevated multiple antimicrobial resistance (MAR) indices (0.54-1). The antimicrobial potentials of green tea (Camellia sinensis), rosemary (Rosmarinus officinalis) and ginger (Zingiber officinale) extracts against MDR Campylobacter isolates were assessed by the disk diffusion assay and broth microdilution technique. Green tea extract showed a marked inhibitory effect against tested isolates, exhibiting growth inhibition zone diameters of 8 to 38 mm and a minimum inhibitory concentration (MIC) range of 1.56-3.12 mg/mL, unlike the rosemary and ginger extracts. Our findings reveal a respectable antibiofilm activity (>50% biofilm formation inhibition) of green tea against the preformed biofilms of Campylobacter isolates. Furthermore, real-time quantitative polymerase chain reaction (RT-qPCR) results showed a significant decrease (p < 0.05) in the expression levels of biofilm biosynthesis gene and its regulator (FlaA and LuxS, respectively) in Campylobacter isolates treated with the green tea extract in comparison with untreated ones. This is the first in vitro approach that has documented the inhibitory activity of green tea extract against MDR-biofilm-producing Campylobacter species isolated from different sources. Further in vivo studies in animals' models should be performed to provide evidence of concept for the implementation of this alternative candidate for the mitigation of MDR Campylobacter infections in the future.

Parents’ preferences for herbal supplements in managing functional gastrointestinal disorders

Gastrointestinal diseases in children and adolescents lead to a considerable impairment of the quality of life of children and parents. Accordingly, there are considerable socio-economic consequences for the family and society. Parents concerned about their children may seek alternative treatments and opt for traditional herbal supplements. This study aimed to determine the utilization status and variety of herbal supplements by parents of children with functional gastrointestinal disorders. 216 study participants were given a socio-demographic questionnaire, a diagnostic questionnaire based on the ROME-IV criteria and a questionnaire with 20 herb names used in traditional treatments. 33.3% of parents reported using “ginger; Zingiber officinale” for their children who were infants and suffered from infantile regurgitation. The herb most preferred by parents for their children with functional gastrointestinal disorders in childhood and adolescence was “spearmint; Mentha spicata” (28.9%). 57.9% of the parents participating in the study stated that they preferred herbal supplements for their children. In addition, 40% of the participants stated that they use the herbs with the advice of the referral. As a result, it has been shown that parents tend to use herbs or herbal supplements, that they need to be educated in the use of these supplements, and that they need access to the right herb and to reliable supplements derived from the right herb.

Treatment of Menopausal Symptoms with Herbal Medicines: A Review

Background: Menopause refers to the natural process of the “cessation of the menstrual cycle.” This phase predominantly affects aged women and can lead to various symptoms such as hot flashes, insomnia, night sweats, and sexual dysfunction, among others. Unfortunately, many women remain unaware of this condition, and some even choose to overlook the symptoms. However, those who recognize the symptoms consult with a doctor, who may recommend Hormone replacement therapy (HRT). Initially, Hormone replacement therapy (HRT) can be effective, but prolonged use can result in side effects. To mitigate these effects, there is a need to explore and investigate herbal therapies as an alternative treatment for menopausal symptoms. Objective: The objective of this review is to explore and summarize various herbs used in managing menopausal symptoms as an alternative to hormone replacement therapy. Methods: For this review, we conducted a literature survey spanning from 1998 to 2023. We used keywords such as menopause, endocrinology, hormone replacement therapy, and herbs used for reducing menopausal symptoms to search databases such as Google Scholar, PubMed, and SciDirect. Relevant data were sourced from various journals like Plos One, JAMA, Frontier, Drug in Context, MDPI, Molecules, BMC Women's Health, Research Gate, Heliyon, Elsevier, Taylor &amp; Francis, Nutrients, JMM, Wiley, OXFORD, Hindawi, Clinical Phytoscience, Pharmaceuticals, Phytomedicine, and Menopause: The Journal of The North American Menopause Society. Results: The literature review encompassed 40 research articles and 200 review articles, including randomized controlled trials. The findings revealed that several herbal plants, including Curcuma longa, Zingiber officinale, Foeniculum vulgare, Trigonella foenum, Actaea racemosa, Glycyrrhiza glabra, Oenothera biennis, Trifolium pratense, Humulus lupulus, Vitex agnus-castus, Valeriana officinalis, Linum usitatissimum, Cannabis sativa, and Asparagus racemosus, have shown efficacy in treating menopausal symptoms. Conclusion: In conclusion, medicinal plants can play a significant role in managing acute menopausal syndrome. The intent of this review is to highlight the most recent research on estrogenic plants for medicinal purposes and their therapeutic impact on cognitive deficiencies brought on by estrogen shortage during menopause and aging.

Designing iron oxide & silver nanocomposites with phyto- and fungo chemicals for biomedicine: lessons learned.

Multifunctional nanoparticles for biomedical applications are widely researched and constantly developed because they provide wider possibilities for therapy and diagnostics. This work aims to summarise our findings towards the design of multifunctional complex iron oxide and silver nanoparticles (NPs) produced from the plants Zingiber officinale and Hypericum perforatum and mushrooms Amanita muscaria and Sparassis crispa. It was revealed that the antimicrobial and anticancer properties of the NPs were a consequence of the combination of silver and phyto- and fungo-chemicals originating from natural species. Moreover, the photoactive properties of the complex iron oxide and silver nanoparticles promoted photodynamic therapy (λexc = 405 nm) that significantly improved the antibacterial (E. coli, S. aureus, B. pumilus, P. fluorescence) and anticancer (HeLa, U2OS cells) effects. Notably, the gel formulations of the NPs based on hyaluronic and alginic acids had advantages over the aqueous dispersions of the NPs. For instance, being embedded into a hyaluronic acid gel, the NPs were more effective against cancer cells due to the improved uptake of hyaluronic acid by cancer cells. Another advantage of gel formulations of the NPs was connected with their microstructural properties; the nanocomposite gel adjusted its microstructure to the substrate topology, mimicking the substrate scale and pattern. Thus, complex ultrasmall iron oxide and silver nanoparticle NPs synthesized with natural extracts and their gel formulations may find diverse applications in the biomedical field, particularly for local cancer treatment and as post-operative bone or tissue scaffold after cancer or chronic osteomyelitis surgery.
