Background: The goal of this study was to evaluate whether medical recommendation of Angocin^® Anti-Infekt N (hereafter referred to as Angocin^®) on the day of diagnosis of an acute upper respiratory tract infection (aURTI) or acute sinusitis (AS) is negatively associated with a recurrence of these diagnoses, incidence of antibiotic prescriptions, incidence of chronic sinusitis, nasal polyps, or sick leave duration. Methods: This retrospective cohort study utilized the IQVIA^TM Disease Analyzer database and included patients by general practitioners with at least one diagnosis of aURTI or AS from 2005 to 2024 and a prescription of Angocin^®, nasal medications (xylometazoline, oxymetazoline) and mucolytics (ambroxol or acetylcysteine), other phytopharmaceutical drugs, or antibiotics on the day of diagnosis. Patients who received Angocin^® were matched separately to each of the three comparison cohorts in a 1:5 ratio using a nearest-neighbor propensity score approach. The relationship between Angocin^® prescription and the risks of a recurrence, subsequent antibiotic use or progression to chronic disease was then estimated with Cox proportional hazard models. To examine whether Angocin^® exposure was associated with the length of sick leave, univariable conditional logistic regression was applied. Results: A total of 3501 Angocin^® patients and 17,505 patients in each further cohort were investigated. Angocin^® prescription was associated with a significantly lower incidence of a newly diagnosed aURTI/AS as compared to other phytopharmaceuticals (Hazard ratio (HR): 0.78; 95% confidence interval (CI): 0.68–0.86), nasal medications and mucolytics (HR: 0.79; 95% CI: 0.71–0.88), or antibiotics (HR: 0.85; 95% CI: 0.77–0.95). In addition, there was a significantly lower incidence of subsequent further prescriptions of antibiotics when compared to other phytopharmaceuticals (HR: 0.92; 95% CI: 0.82–0.99), nasal medications and mucolytics (HR: 0.87 (95%; CI: 0.80–0.95), or antibiotics (HR: 0.62; 95% CI: 0.57–0.67). Furthermore, Angocin^® was associated with the most advantageous pattern of work absence across all time periods examined. Conclusions: Considering the limitations of the study, the results cast a positive light on Angocin^® prescription in the management of aURTI/AS, particularly with regard to recurrence rates, subsequent antibiotic prescriptions, and sick leave duration.

Armoracia rusticana (horseradish) is rich in bioactive compounds such as glucosinolates, phenolic compounds, and vitamin C, highlighting promising potential for innovative food applications, while its use in food packaging materials remains largely unexplored. This study aimed to evaluate how the concentration of horseradish root powder affects the properties of novel bioactive membranes formulated with sodium alginate, glycerol and soy lecithin. The physicochemical, mechanical, barrier and optical properties of the membranes, as well as their specific antioxidant and antimicrobial capacity, were investigated. The structure of the membranes was analyzed in terms of the functional groups and the possible interactions between the polymer matrix components using FT-IR analysis. Alongside microscopic observation of the membrane surfaces at 40× magnification, the roughness of the membranes was investigated, as well as the influence of parameters corresponding to the homogeneity and uniformity of the developed edible food membranes. The results show significant differences in the determined properties, highlighting good barrier capacity against water vapor and UV radiation, as well as high tensile strength and elongation at break values of 17.54 ± 1.18 N and 65.6 ± 9.63%, respectively. Values progressively increase as the content of incorporated plant material rises. The addition of horseradish positively influenced the composition of the membranes, increasing their antioxidant activity values by up to 34.92 ± 0.06%. Full article

Moringa oleifera, widely recognized as the horseradish tree or drumstick tree, is classified within the Moringaceae family, which comprises 13 species predominantly distributed across tropical and subtropical regions. The plant possesses a variety of therapeutic, nutritional, and beneficial health properties, including its potential to enhance the immune system. The present work provides extensive bibliographic research addressing the chemical composition of Moringa oleifera and its immunomodulatory properties with a focus on the cellular and molecular mechanisms involved in the regulation of immune function, which is crucial in unchecked cell proliferation and metastasis. The chemical composition of Moringa oleifera, including kaempferol, chlorogenic acid, quercetin, and niazimicin, varies between different biological parts of the plant (seeds, leaves, roots, and stems). The presence of these various chemical compounds contributes to the plant’s effect on the immune response via different pathways. Several studies indicate that Moringa oleifera mitigates inflammation by suppressing key pro-inflammatory mediators, such as TNF-α, IL-1β, inducible nitric oxide synthase (iNOS), prostaglandin E2 (PGE-2), and cyclooxygenase-2 (COX-2), while simultaneously enhancing anti-inflammatory mediators through activation of PPAR-γ. Furthermore, the immunomodulatory properties and possible application in health promotion and disease prevention, especially in cancer therapy, are discussed. Studies indicate that Moringa oleifera can modulate the tumor microenvironment (TME) by reducing Treg polarization, enhancing NK cell cytotoxicity, and prompting the proliferation and clonal expansion of CD8⁺ and CD4⁺ T lymphocytes. Together, Moringa oleifera could be considered for the treatment of conditions related to immune dysregulation, such as cancer. Full article

Horseradish (Armoracia rusticana L.) root (HRP) and leaf (HLP) pomaces, by-products of juice production by cold-pressing, were analyzed as a novel potential source of natural antioxidants. Chromatography analysis (UHPLC Q-ToF MS) of the bioactive compounds of pomaces was performed along with spectrophotometric determination of total phenolic content (TPC), total flavonoid content (TFC), total phenolic acid (hydroxycinnamic) content (TPAC), and antioxidant capacity (via 1,1-diphenyl-2-picrylhydrazyl (DPPH^•) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic-acid) (ABTS^•+) radicals’ scavenging activity and ferric reducing antioxidant power (FRAP)). The concentrations of TPC, TFC, and TPAC differed among the pomaces, significantly favoring HLP. However, both horseradish pomaces (HRP and HLP) contained a considerable amount of various phenolics, with kaempferol and its glucosides dominating. In addition, they exhibit pronounced antioxidant activity, which is confirmed by all three methods used (DPPH, ABTS, and FRAP). These results highlight the potential of valorizing horseradish processing waste as a natural, reliable source of health-promoting bioactive compounds and functional ingredients in food products, thereby fortifying food, preventing oxidation, and prolonging shelf-life. In addition, this study supports endeavors to reduce food waste by providing new insights into the valorization of horseradish pomace, thus contributing to sustainable development and environmental protection.

Background/Objectives: Horseradish (Armoracia rusticana L.) roots—largely used in traditional medicine for their multiple therapeutic effects—are a rich source of health-promoting phytochemicals. However, their efficacy can be compromised by low chemical stability and poor bioavailability. Incorporation into phospholipid vesicles is often proposed to tackle this problem. Methods: In this study, a hydroalcoholic extract was produced from horseradish roots. The extract was characterized by UPLC-MS and HPLC-PDA and formulated in conventional liposomes and Penetration Enhancer-containing Vesicles (PEVs) for skin application. Results: The obtained nanovesicles were small in size (<100 nm), negatively charged, uni/bilamellar, and with high values of entrapment efficiency (>85%) for the flavonoids identified in the extract. Both the free and the nanoformulated extract showed optimal biocompatibility, measured as the absence of hemolysis of erythrocytes and absence of cytotoxicity in skin cell lines. Furthermore, the nanoformulations displayed antioxidant activity in vitro. Conclusions: The proposed nananoformulations could be exploited to counteract oxidative stress involved in the pathogenesis and progression of numerous skin disorders. Full article

Background: The goal of this study was to evaluate whether the medical recommendation of Angocin^® Anti-Infekt N, compared to standard antibiotic treatment shortly after the diagnosis of a urinary tract infection (UTI) or cystitis, is negatively associated with an early, sporadic, or recurrent UTI, subsequent antibiotic prescriptions, pyelonephritis as a renal complication, or UTI-associated sick leave. Methods: This retrospective cohort study was based on data from the IQVIA^TM Disease Analyzer database and included patients diagnosed with acute UTI or cystitis by physicians in Germany between 2005 and 2021, who were prescribed either Angocin^® or standard antibiotics within 4 days after diagnosis. Patients prescribed antibiotics were matched to those prescribed Angocin^® (5:1) using propensity scores. Univariable logistic and Cox regression models were used to investigate the association between Angocin^® prescription and the defined study outcomes. The effects of Angocin^® were adjusted for age, sex, insurance status, index diagnosis, and physician specialty. Results: A total of 2277 Angocin^® patients and 11,385 antibiotic patients were available for analysis. Compared to antibiotic prescriptions, Angocin^® prescription was associated with significantly lower odds of an early relapse within 1–30 days after the index date (odds ratio (OR): 0.74; 95% confidence interval (CI): 0.62–0.87; p < 0.001), further sporadic UTI within 31–365 days after the index date (OR: 0.68; 95% CI: 0.58–0.78; p < 0.001), and recurrent UTI (OR: 0.63; 95% CI: 0.48–0.82; p < 0.001). This was also accompanied by reduced antibiotic prescriptions (1–30 days: OR: 0.63; 95% CI: 0.53–0.74, p < 0.001; 31–365 days: OR: 0.56; 95% CI: 0.49–0.64, p < 0.001). A strong, but due to the low incidence, not significant, negative association was observed between Angocin^® prescription and the occurrence of pyelonephritis (hazard ratio (HR): 0.67; 95% CI: 0.43–1.06; p = 0.073). Conclusions: The results of this real-world data study demonstrate that Angocin^® can be an effective therapeutic option for managing acute and recurrent UTIs and serves as an alternative therapy to antibiotics.

The glucosinolates of Brassicaceae plants are converted into bioactive isothiocyanates and other volatiles during a challenge by pathogens and other biotic stressors. However, the role of alternative downstream products with weaker potency (e.g., nitriles) is far from being fully understood. This study tested the possible synergistic antifungal interaction between various glucosinolate-derived nitriles and 2-phenylethyl isothiocyanate (PEITC) on 45 fungal strains, including endophytes from horseradish roots (Brassicaceae) and soil fungi, using an airtight system enabling the accurate study of extremely volatile antifungal agents. The median minimal inhibitory concentrations (MICs) were 1.28, 6.10, 27.00 and 49.72 mM for 1H-indole-3-acetonitrile (IAN), 3-phenylpropanenitrile (PPN), 4-(methylsulfanyl)-butanenitrile (MSBN) and 3-butenenitrile (BN, = allyl cyanide), respectively. Thus, nitriles were considerably weaker antifungal agents compared to PEITC with a median MIC of 0.04 mM. For the same nitriles, the median fractional inhibitory concentration indices (FICIs) of the combinations were 0.562, 0.531, 0.562 and 0.625, respectively. Altogether, 47.7%, 56.8%, 50.0% and 27.3% of tested fungal strains showed a synergistic antifungal activity (FICI ≤ 0.5) for the nitrile–isothiocyanate combinations, respectively. Hypocreales strains showed the least sensitivity towards the GSL decomposition products and their combinations. The mean MIC values for PEITC showed 0.0679 ± 0.0358, 0.0400 ± 0.0214, 0.0319 ± 0.0087 and 0.0178 ± 0.0171 mM for Hypocreales, Eurotiales, Glomerellales and Pleosporales, respectively. In addition, nitriles, especially IAN, also showed significant differences. For the same fungi, the median FICI values fell in the ranges of 0.61–0.67, 0.52–0.61, 0.40–0.50 and 0.48–0.67, respectively, depending on the nitrile. Our results suggest that glucosinolate-derived nitriles may enhance isothiocyanate antifungal activity and that they may play an active role in shaping the plant microbiome and contribute to the filtering of microbes by plants.

In this study, biosensors based on two types of screen-printed carbon and Prussian blue-carbon electrodes, respectively, modified with peroxidase extracted from horseradish root for the sensitive and selective detection of caffeic acid were developed. The presence of the enzyme in the aqueous extract and the activity of peroxidase was demonstrated by spectrometric methods. The electrochemical technique used for the determination of caffeic acid with the biosensors was the cyclic voltammetry. Calibration of the biosensors towards caffeic acid was carried out in solutions of different concentrations, ranging from 5 to 74 μM. Suitable sensitivities and detection limits for practical applications were obtained, with the more sensitive (0.72 μA·μM⁻¹) one being the biosensor containing Prussian blue as a mediator of the exchange between electrons with a detection limit of 0.9 μM. Caffeic acid was successfully determined and quantified in three food supplements using the Prussian blue-peroxidase-based biosensor. The method used to validate the results obtained with the biosensor in the food supplements was a comparison with the amounts indicated by the producers, with no differences between the results at a 99% confidence level.

Root vegetables are known all over the world, but they are being less and less consumed by individuals. The main purpose of this article was to summarize the benefits, health effects, and threats associated with the consumption of carrot, celery, parsley, beetroot, radish, turnip, and horseradish. They are characterized by high nutritional value due to their richness in dietary fiber, vitamins, and minerals. One of their most important features is their high content of bioactive compounds, such as polyphenols, phenols, flavonoids, and vitamin C. These compounds are responsible for antioxidant potential. Comparison of their antioxidant effects is difficult due to the lack of standardization among methods used for their assessment. Therefore, there is a need for a reference method that would allow for correct interpretation. Moreover, root vegetables are characterized by several health-promoting effects, including the regulation of metabolic parameters (glucose level, lipid profile, and blood pressure), antioxidant potential, prebiotic function, and anti-cancer properties. However, due to the type of cultivation, root vegetables are vulnerable to contaminants from the soil, such as toxic metals (lead and cadmium), pesticides, pharmaceutical residues, microplastics, and nitrates. Regardless, the low levels of toxic substances present in root vegetables do not pose health risks to the average consumer. Full article

Dehydrodiisoeugenol (DHIE) is a neolignan found in more than 17 plant species, including herbs, fruit, and root. DHIE was, for the first time, isolated from Myristica fragrans bark in 1973. Since then, many methodologies have been used for the obtention of DHIE, including classical chemistry synthesis using metal catalysts and biocatalytic synthesis; employing horseradish peroxidase; peroxidase from Cocos nucifera; laccase; culture cells of plants; and microorganisms. Increasing evidence has indicated that DHIE has a wide range of biological activities: anti-inflammatory, anti-oxidant, anti-cancerogenic, and anti-microbial properties. However, evidence in vivo and in human beings is still lacking to support the usefulness potential of DHIE as a therapeutic agent. This study’s review was created by searching for relevant DHIE material on websites such as Google Scholar, PubMed, SciFinder, Scholar, Science Direct, and others. This reviews the current state of knowledge regarding the different synthetical routes and biological applications of DHIE. Full article

Despite the high value of ramson (Allium ursinum) in medicine and nutrition, it is not cultivated in open fields due to the need for shading as well as weeding during the early crop stages. Research was carried out in an open field with the aim to improve A. ursinum growth, through its intercropping with Armoracia rusticana (horseradish). In the latter context, with and without sodium selenate application, ramson and horseradish showed reciprocal growth stimulation, as ramson biomass increased by 1.28 times and horseradish root biomass by 1.7 times. The biofortification level of horseradish roots increased from 5.9 to 9.6 times due to joint plant growth under selenium (Se) supply. The opposite phenomenon was recorded for ramson leaves, as the biofortification level decreased from 11.7 in the case of Se supplementation to 6.7 in plants supplied with sodium selenate when jointly cultivated with horseradish. Among the tested antioxidants, the highest increase due to joint cultivation and/or Se supply was recorded for ascorbic acid by 1.69 times in ramson leaves and 1.48 and 1.37 times in horseradish roots and leaves, respectively. All treatments significantly increased the total antioxidant activity (AOA) of horseradish leaves (by 1.33–1.49 times) but not roots. Comparison of the results obtained in field conditions with those obtained earlier for the Se biofortification of ramson in the natural habitat (forest) revealed significantly higher levels of the plant’s antioxidant status under environmental stress (field) and a decrease in the correspondent differences as a consequence of Se biofortification. The estimation of allelopathic beneficial interaction between ramson and horseradish implies the efficiency of ramson growth and production of functional food with high levels of Se (Se–ramson leaves and Se–horseradish roots).

In the present study, we assessed the allelopathic effects of various concentrations (0%, 0.1%, 0.2%, and 0.3%) of horseradish root extract (HRE) on onion root. The average growth of onion root tips during the 0% HRE treatment (deionized water treatment) was 0.9 cm/day, which was the highest among the growth rates obtained with all HRE treatments. Moreover, the average growth during 0.3% HRE treatment was 0.1 cm/day. During cell cycle analysis, the mitotic phase fraction of the control (deionized water treatment) cells was 6.5% of all dividing cells, with this percentage being the highest among the values obtained for all treatment groups. In the control group, all cell cycle phases were identified; however, in the 0.1%, 0.2%, and 0.3% treatment groups, telophase was not identified. The ROS accumulation area of the onion root decreased, as the HRE treatment concentration increased. In the control root, the area of dead tissue was 0%; however, in the 0.1% and 0.2% HRE treatment roots, the ratio was 5% and 50%, respectively. These findings indicate that the allelopathic effect of HRE depends on the concentration of HRE applied to the onion root. Full article

Increased proliferation of algae is a current problem in natural and artificial water bodies. Controlling nutrients is the most sustainable treatment of increased algal proliferation, however in certain cases, it is not sufficiently available, or it does not provide results fast enough. Chemicals derived from natural sources, which could be effective in low concentrations and are biodegradable, may have an advantage over conventional chemical treatments. The main aim of the present study was to investigate the anti-cyanobacterial and anti-algal properties of allyl-isothiocyanate-containing essential oil produced from horseradish roots with a complex approach of the topic: on laboratory strains of cyanobacteria and eukaryotic algae, on microcosms containing natural phytoplankton assemblages, and on semi-natural biofilms. The results show that acute treatment can significantly reduce the viability of all the tested cyanobacteria and eukaryotic algae. Results of microcosm experiments with natural phytoplankton assemblages show that horseradish essential oil from 7.1 × 10⁻⁶% (v/v) is applicable to push back phytoplankton proliferation even in natural assemblages. The individual number in the biofilm was dropped down to one-fifth of the original individual number, so 7.1 × 10⁻⁶% (v/v) and higher concentration of the essential oil can be considered as a successful treatment against biofouling.

Horseradish is a flavorful pungent herb that has been used for centuries to enhance the flavor of food, aid in digestion, and improve human health. Horseradish is a neglected and underutilized plant species (NUS), especially concerning the potential benefits to improve human health. The roots of this plant have been known for centuries to provide effective treatments for various human health disorders and has a long history of use in traditional medicine. Horseradish is a source of many biologically active compounds and its richness in phytochemicals has encouraged its recent use as a functional food. The medicinal benefits of horseradish are numerous, and this plant should be promoted more as being beneficial for human health. Glucosinolates or their breakdown products, isothiocyanates, are responsible for most of the claimed medicinal effects. Recent studies have suggested that glucosinolates provide prevention and inhibitory influences on different types of cancer, and horseradish contains high amounts of these compounds. Other medicinal benefits of horseradish include its well-known antibacterial properties that are also attributed to isothiocyanates, and its high content of other antioxidants that benefit human health. Additionally, horseradish contains enzymes that stimulate digestion, regulate bowel movement, and reduce constipation. Horseradish is a species that is vastly underexploited for its abilities as a medicinal plant species for improving human health. The health promoting effects of horseradish are numerous and should be used in an extensive marketing campaign to improve consumption habits. Consumers need to be made more aware of the tremendous health benefits of this plant, which would most likely increase consumption of this valuable NUS. Although horseradish is a highly versatile plant species and holds great potential for improving human health, this plant can also be used to enhance biodiversity in landscapes and food systems, which will also be briefly discussed.

Horseradish cultivars are highly heterozygous clones and are maintained through asexual propagation, using root cuttings. For many years, horseradish was believed to be sterile and therefore impossible to improve by traditional sexual crosses. Prior to the 20th century, the only way to improve horseradish was to select and plant root cuttings from the most desirable plants. Moreover, the development of new improved horseradish cultivars has also been somewhat limited by the lack of viable seed resulting from low fertility of horseradish flowers. However, in Illinois, USA, a horseradish breeding program was initiated in the 1950s to develop additional cultivars to widen the genetic base of the few cultivars being grown at the time. In more recent years, the proven cross breeding technique has been primarily used to obtain new genotypes of horseradish, since it is more efficient in producing new improved cultivars, compared to the polycross method that had been previously used for decades to obtain new genetic combinations. Since horseradish is a minor specialty crop with very little available information regarding breeding procedures, this review was developed to provide a better understanding of pollination barriers and methods for fertility improvement, traditional breeding procedures and cultivar development, and traditional breeding achievements and limitations. The development of new horseradish cultivars is essential for the sustained success of the Illinois, USA industry since it provides growers with a continuous supply of new selections that have increased vigor, outstanding root quality, and high yields.
