The analgesic effect of paeoniflorin: A focused review.

Pain has been a prominent medical concern since ancient times. Despite significant advances in the diagnosis and treatment of pain in contemporary medicine, there is no a therapeutic cure for chronic pain. Chinese herbaceous peony, a traditional Chinese analgesic herb has been in clinical use for millennia, with widespread application and substantial efficacy. Paeoniflorin (PF), the main active ingredient of Chinese herbaceous peony, has antioxidant, anti-inflammatory, anticancer, analgesic, and antispasmodic properties, among others. The analgesic effect of PF, involving multiple critical targets and pain regulatory pathways, has been a hot spot for current research. This article reviews the literature related to the analgesic effect of PF in the past decade and discusses the molecular mechanism of the analgesic effect of PF, including the protective effects of nerve cells, inhibition of inflammatory reactions, antioxidant effects, reduction of excitability in nociceptor, inhibition of the nociceptive excitatory neuroreceptor system, activation of the nociceptive inhibitory neuroreceptor system and regulation of other receptors involved in nociceptive sensitization. Thus, providing a theoretical basis for pain prevention and treatment research. Furthermore, the prospect of PF-based drug development is presented to propose new ideas for clinical analgesic therapy.

Handshake of deep eutectic solvent and ionic liquid: Two liquid-liquid microextraction procedures for plant analysis.

Plants are subjects of interest due to the secondary metabolites in their extracts which are promising as new pharmaceuticals. Phytochemistry do not have united system of sample preparation or analysis still due to different structure of plant cells, wide broad range of chemical properties and concentrations of bioactive compounds. Such challenges can be addressed in a green chemistry manner using new approaches through smart materials in routine monitoring and researches. Liquid smart materials, such as ionic liquids (ILs) and deep eutectic solvents (DESs) are attractive due to flexible properties, lots of extraction approaches, recycle potential, and direct compatibility with powerful analytical methods. In this study DES-based microextraction procedure with pH-switching was developed. Four choline chloride DESs were suggested as selective extraction phases for polar compounds from acetonitrile extracts. Method was successfully tested on four plants (Iris sibirica L., Hypericum perforatum L., Scutellaria baicalensis G, Citrus reticulata B.). Developed procedure was optimized and validated for the choline chloride - urea (1:2 mol/mol) DES that demonstrated better results in extraction. LOD for rutin was found as 0.05 mg ml-1. For low-polar compound, imidazolium ionic liquid-based dispersive liquid-liquid microextraction procedure was developed. 1-hexyl-3-methylimidazolium salts have demonstrated desired selectivity. The main factors influencing the extraction efficiency have been identified and optimized by design of experiment on two model plants (Iris sibirica L. and Scutellaria baicalensis G.). Validation procedures were done for thymol. LOD for thymol was found as 0.021 mg ml-1. The methods were compared with each other and traditional methanol extraction. The selectivity of the smart materials supports each other, usage of such extraction phases provides same or better results as obtained with methanol.

Efficacy of Dichrostachys Glomerata Supplementation on Overweight and Mildly Obese Adult's Weight, Mood, and Health-Related Quality of Life: A Randomized Double-Blind Placebo-Controlled Trial.

Despite their widespread use, research is needed to evaluate the weight loss and related health/wellness outcomes of herbal plants. Preliminary research found that the fruit of Dichrostachys glomerata is safe and has potential weight loss effects. This study aimed to examine the effect of a standardized powder of D. glomerata fruit pods (DYG-400®) on weight, food cravings, mood, and health-related quality of life of overweight and mildly obese adults. In this CONSORT-compliant double-blind placebo-controlled trial, 56 adults (Mean [M] age = 44.50, M [body mass index] BMI = 31.66) were randomized to either the D. glomerata Group (DG; 300 mg/d) or Placebo Group (PG; rice protein, 300 mg/d) for 60 days. Participants weight was assessed along with self-report assessments of the Food Cravings Questionnaire, CDC Health-related Quality of Life, Perceived Stress Scale, Trait Anxiety Inventory, and Profile of Mood States at Baseline, Day 30, and Day 60. The data were collected from March 2023 to June 2023 and stored electronically, and analyzed using general linear models with repeated measures. DG lost more weight at Day 60 compared to PG, p = .05 (4.11 vs. 2.19 lbs). DG had reduced food cravings from Baseline to Day 30 and Day 60 compared to PG, p < .001. Perceived stress, p < .001, and mood, p = .017, improved from Baseline to Day 60 for DG compared to PG. Anxiety decreased from Baseline to Day 60 for DG and from Baseline to Day 30 for PG, p < .001. Health-related Quality of Life improved for DG compared to PG, p < .001. D. glomerata (DYG-400®) may be an effective herbal intervention to promote weight loss and health. Extended clinical trials across diverse populations and settings are needed.Clinical trial registry number and website: ISRCTN10099861, https://doi.org/10.1186/ISRCTN10099861.

Mechanism of Traditional Chinese Medicine in Treating Migraine: A Comprehensive Review.

Migraine is a common neurological illness that causes a great burden on individuals and society. Many migraine patients seek relief through complementary and alternative therapies, with Traditional Chinese medicine (TCM) often being their preferred choice. Acupuncture, Chinese herbal medicine, and massage are important components of TCM, and are commonly used in clinical treatment of migraine. This review aims to consolidate the current knowledge regarding the mechanisms of the three TCM interventions for migraine: acupuncture, herbs, and massage, and how they relieve pain. However, the mechanisms underlying the effectiveness of TCM therapies in treating migraine remain unclear. Therefore, we reviewed the research progress on acupuncture, herbal medicine, and massage as TCM approaches for the treatment of migraine. We conducted a comprehensive search of CNKI, PubMed, Web of Science, and Cochrane databases using keywords such as migraine, acupuncture, needle, herbs, herbal, prescription, decoction, massage, Tuina, and TCM, covering the period from 2000 to 2023. The literature included in the review was selected based on specified exclusion criteria. We discussed the mechanism of TCM therapies on migraine from the perspective of modern medicine, focusing on changes in inflammatory factors, neurotransmitters, and other relevant biomarkers. TCM can relieve migraine by decreasing neuropeptide levels, inhibiting inflammation, modulating neuronal sensitization, changing brain function and structure, changing blood brain barrier permeability, regulating hormone levels, and relieving muscle tension. The purpose of this paper is to provide a basis for improving the clinical strategies of TCM for the treatment of migraine.

Perspective: Key Considerations When Developing and Publishing Dietary Interventions for Human Clinical Trials.

A key guiding principle in the 2020-2025 Dietary Guidelines for Americans emphasizes the need for individuals to choose eating habits that allows for personal, cultural, and traditional preferences while establishing a high-quality diet. This concept becomes a daunting task given the need to reduce the consumption of foods higher in saturated fat, sodium, and/or added sugar-which are typically found in familiar, highly palatable foods most-often liked and consumed in the United States. Similarly, in nutrition intervention studies, adherence to healthier dietary patterns is typically low because of many factors, including reduced taste, flavor, and familiarity to the study foods. Increasing evidence illustrates the promising role of herbs and spices to maintain acceptability of healthier food options for nutrition interventions. This perspective article was informed by a Satellite Session presented at the American Society for Nutrition's annual meeting, Nutrition 2023, entitled, "Developing Culturally Appropriate Recipes for Human Clinical Trials," which explored several proposed best practice guidelines when developing nutrition interventions to improve dietary adherence and acceptability within clinical trials. The session also highlighted a need to include sufficient detail concerning the types and amounts of specific foods included within nutrition interventions in combination with preparation methods and study recipes, including herbs and spices, to improve intervention reproducibility and translatability for future research, dietary guidelines, and clinical practice.

[Review of contributing factors and research model of "excellent shape, high quality, and superior effect" of Dao-di herbs].

Based on the research results and development trend of modern life sciences, our team first proposed in 2020 that Dao-di herbs had the characteristics of "excellent shape, high quality, and superior effect", which broadened the scope of traditional medicinal herb description. In recent years, with the gradual deepening of the research on the natural, material, and medicinal properties of Dao-di herbs in traditional Chinese medicine(TCM), the scientific connotation of "excellent shape, high quality, and superior effect" of Dao-di herbs has been enriched. "High quality" is mainly embodied in the fact that Dao-di herbs have a "unique chemotype", which can be used as the material basis of "superior effect" and can participate in regulating the formation of "excellent shape". Similar to the principle of "unity of body and spirit", in the process of long-term evolution, Dao-di herbs gradually form unique environmental adaptive characteristics, which is manifested as the "unity of shape and quality". The characteristics of "excellent shape, high quality, and superior effect" of Dao-di herbs are affected by the interaction between the genotype of the species and the ecological factors of the production area, which can be reflected in the climate-dominated type, production measure-dominated type, or germplasm-dominated type. According to the natural, material, and medicinal attributes of Dao-di herbs, model organisms such as Salvia miltiorrhiza can be constructed, and the research methodology system of the characteristics of "excellent shape, high quality, and superior effect" can be established, including quality evaluation system based on "high quality", characterization methodology system of "property-efficacy relationship", and homeostatic comprehensive control system based on "excellent shape and high quality". In the future, research on Dao-di herbs should pay more attention to in-depth and extensive basic work, and it is necessary to establish a comprehensive medicinal model plant research platform and build a medicinal model plant mutant library, so as to provide powerful model organisms for the functional gene research of other plants. Meanwhile, three research hotspots have been proposed for the research on the characteristics of "excellent shape, high quality, and superior effect" of Dao-di herbs, so as to reveal the mechanisms of their genetic basis, biological characteristics, and ecological adaptability. These studies will provide a scientific basis for optimizing the directed breeding of medicinal plants, standardizing cultivation, and improving the quality of medicinal herbs, so as to promote the sustainable use and development of Dao-di herbs.

BACKGROUND: The use of herbal products, one component of the growing field of integrative cancer care, is a common yet controversial practice. OBJECTIVES: This article distinguishes nursing issues specific to patient safety when herbal products are used during cancer treatment and identifies available evidence-based resources to enhance patient and professional comprehension. METHODS: PubMed®, CINAHL®, and Google Scholar™ databases were searched for literature published between 2018 and 2024 specific to the clinical sequelae of the use of herbal products and their interactions with antineoplastic drugs, as well as patient and healthcare providers' perceptions of efficacy and safety. FINDINGS: Patients have misconceptions about the use of herbal products and are generally unaware of these products' potential contraindications when taken in conjunction with antineoplastics. Providers seldom inquire about patients' use of these products and may lack knowledge of their potential interactions with prescription medicines.

Beyond Pharmacology: A Narrative Review of Alternative Therapies for Anxiety Disorders.

BACKGROUND: Anxiety disorders significantly reduce patients' quality of life. Current pharmacological treatments, primarily benzodiazepines and antidepressants, are associated with numerous side effects. Consequently, there is a continual search for alternative methods to traditional therapies that are less burdensome for patients and broaden their therapeutic options. Our objective was to determine the role of selected alternative methods in the treatment of anxiety disorders. METHODS: In this review, we examined recent evidence on alternative treatments for anxiety disorders, including physical activity, mindfulness, virtual reality (VR) technology, biofeedback, herbal remedies, transcranial magnetic stimulation (TMS), cryotherapy, hyperbaric therapy, vagus nerve stimulation (VNS), 3,4-methylenedioxymethamphetamine (MDMA), electroconvulsive therapy (ECT), and eye movement desensitization and reprocessing (EMDR) therapy. For this purpose we reviewed PubMed and after initial search, we excluded works unrelated to our aim, non-orginal data and animal studies. We conducted second search to cover all minor methods. RESULTS: We included 116 studies, which data is presented in Tables. We have investigated which methods can support treatment and which can be used as a stand-alone treatment. We assessed the risks to benefits of using alternative treatments. CONCLUSION: Alternative treatments significantly expand the options available to patients and clinicians, with many serving as adjuncts to traditional therapies. Among the methods presented, mindfulness has the most significant therapeutic potential.

Application of Mass Spectrometry for Analysis of Nucleobases, Nucleosides and Nucleotides in Tea and Selected Herbs: A Critical Review of the Mass Spectrometric Data.

The main and most commonly known biological function of nucleobases, nucleosides, and nucleotides is usually associated with the fact that they are the building blocks of nucleic acids. However, these compounds also belong to plant secondary metabolites, although in that role they have attracted less attention than the others, e.g., terpenes, phenolics, or alkaloids. The former compounds are also important constituents of the human diet, e.g., as ingredients of tea and herbs, endowing them with specific taste qualities and pharmacological activities. Liquid chromatography-mass spectrometry seems to be the most important analytical method that permits the identification and determination of nucleobases, nucleosides, and nucleotides, along with the other metabolites. The main goal of this review is to discuss in detail the aspects of mass spectrometric detection of nucleobases, nucleosides, and nucleotides in tea and selected herbs. An important conclusion is that the identification of the compounds of interest should be performed not only on the basis of [M + H]+/[M - H]- ions but should also be confirmed by the respective product ions; however, as discussed in detail in this review, it may sometimes be problematic. It also clear that all difficulties that may be encountered when analyzing plant material are caused by the complexity of the analyzed samples and the need to analyze different classes of compounds, and this review absolutely does not debase any of the mentioned papers.

Therapeutic Potential of Natural Resources Against Endometriosis: Current Advances and Future Perspectives.

Endometriosis (EMS) is defined as the appearance, growth, infiltration, and repeated bleeding of endometrioid tissue (glands and stroma) outside the uterus cavity, which can form nodules and masses. Endometriosis is a chronic inflammatory estrogen-dependent disease and occurs in women of reproductive age. This disorder may significantly affect the quality of life of patients. The pathogenic processes involved in the development and maintenance of endometriosis remain unclear. Current treatment options for endometriosis mainly include drug therapy and surgery. Drug therapy mainly ties to the use of non-steroidal anti-inflammatory drugs (NSAIDs) and hormonal drugs. However, these drugs may produce adverse effects when used for long-term treatment of endometriosis, such as nausea, vomiting gastrointestinal reactions, abnormal liver and kidney function, gastric ulcers, and thrombosis. Although endometriosis lesions can be surgically removed, the disease has a high recurrence rate after surgical resection, with a recurrence rate of 21.5% within 2 years and 40% to 50% within 5 years. Thus, there is an urgent need to develop alternative or additional therapies for the treatment of endometriosis. In this review, we give a systematic summary of therapeutic multiple component prescriptions (including traditional Chinese medicine and so on), bioactive crude extracts of plants/herbs and purified compounds and their newly found mechanisms reported in literature in recent years against endometriosis.

Improving the food safety of bakery products by simultaneously monitoring the occurrence of pyrrolizidine, tropane and opium alkaloids.

The exponential number of food alerts about concerning levels of some plant-alkaloids, such as pyrrolizidine, tropane and opium alkaloids, have stressed the need to monitor their occurrence in foods to avoid toxic health effects derived from their intake. Therefore, analytical strategies to simultaneously monitor the occurrence of these alkaloids should be developed to ensure food safety an comply with regulations. Accordingly, this work proposes an efficient multicomponent analytical strategy for the simultaneous extraction of these alkaloids from commercial bakery products. The analytical method was validated and applied to the analysis of 15 samples, revealing that 100% of them contained at least one of the target alkaloids, in some cases exceeding the maximum limits legislated. Moreover, in two samples the 3 different alkaloid families were detected. These results confirm the importance of simultaneously monitoring these alkaloids in food and highlight also considering some opium alkaloids in current legislation.

A New Frontier in Phytotherapy: Harnessing the Therapeutic Power of Medicinal Herb-derived miRNAs.

Medicinal herbs have been utilized in the treatment of various pathologic conditions, including neoplasms, organ fibrosis, and diabetes mellitus. However, the precise pharmacological actions of plant miRNAs in animals remain to be fully elucidated, particularly in terms of their therapeutic efficacy and mechanism of action. In this review, some important miRNAs from foods and medicinal herbs are presented. Plant miRNAs exhibit a range of pharmacological properties, such as anti-cancer, anti-fibrosis, anti-viral, anti-inflammatory effects, and neuromodulation, among others. These results have not only demonstrated a cross-species regulatory effect, but also suggested that the miRNAs from medicinal herbs are their bioactive components. This shows a promising prospect for plant miRNAs to be used as drugs. Here, the pharmacological properties of plant miRNAs and their underlying mechanisms have been highlighted, which can provide new insights for clarifying the therapeutic mechanisms of medicinal herbs and suggest a new way for developing therapeutic drugs.

Diversity and functional differentiation of renewal buds in temperate herbaceous plants.

Spring regrowth in temperate perennials relies on renewal buds, which form a key component in the shoot growth cycle. Still, we possess almost no information on these renewal buds, which is becoming more pressing with the current climate change. Most existing studies concentrated on easy-to-study aboveground buds of woody plants, whose morphology has largely been linked to frost protection. It is not clear to what extent these findings apply also to herbaceous species. We therefore examined protective traits and preformation of winter renewal buds in 379 species of temperate herbs, and tested how these traits are distributed across the phylogeny and related to other bud bank and whole-plant traits. We identified a major gradient from few, large, highly preformed, scale-covered buds associated with larger belowground storage organs deep in the soil, to small, numerous, less preformed, and naked buds near the soil surface. Belowground renewal buds of temperate herbs show several distinct strategies for winter survival and spring regrowth that might affect their response to changing winter and early spring conditions. Renewal bud traits are driven not only by frost protection but also by protection of the apical meristem from mechanical disturbance in the soil.

Anti-HIV activity in traditional Chinese medicine: clinical implications of monomeric herbal remedies and compound decoctions.

With the global spread of human immunodeficiency virus (HIV) infection and acquired immune deficiency syndrome (AIDS), the pursuit of potent treatments has ascended as a paramount concern in global healthcare. Traditional Chinese medicine (TCM) has been used for thousands of years in China and other East Asian countries and it offers remedies for an extensive array of ailments, including HIV and AIDS. This review focuses on the clinical significance of single herbs and composite tonics in TCM with antiviral activity against HIV. Initially, the anti-HIV activity of single herbs was analyzed in detail. Many herbs have been shown to have significant anti-HIV activity. The active ingredients of these herbs exhibit their anti-HIV effects through various mechanisms, such as inhibiting viral replication, preventing viral binding to host cells, and interfering with the viral lifecycle. Furthermore, we delved into the clinical significance of HIV-associated formulations provided as a result of Chinese compound prescription. These combinations of herbal ingredients are designed to amplify therapeutic efficacy and minimize adverse effects. Clinical trials have demonstrated the therapeutic benefits of these prescriptions for individuals infected with HIV. The intricate composition of these prescriptions potentially augments their anti-HIV activity through synergistic effects. Additionally, this review underscores the clinical importance of TCM in the context of HIV treatment. While numerous herbs and prescriptions exhibit anti-HIV activity, their safety and efficacy in clinical applications warrant further investigation. When combined with contemporary antiretroviral drugs, TCM may serve as an adjunctive therapy, assisting in reducing side effects, and enhancing patients' quality of life. To optimally harness these natural resources, further exploration is imperative to ascertain their efficacy, safety, and optimal utilization, thereby offering a broader spectrum of therapeutic options for HIV-afflicted individuals.

Growth performance of African catfish (Clarias gariepinus) in aquaponic systems with varying densities of Vietnamese coriander (Persicaria odorata).

Mass cultivation of high-value aromatic herbs such as Vietnamese coriander and Persicaria odorata required specific soil, nutrients, and irrigation, mostly found in the limited natural wetland. This study aimed to evaluate the capacity of P. odorata at different densities in nutrient removal and the growth performance of African catfish, Clarias gariepinus in aquaponic systems. P. odorata was cultivated for 40 d with less than 10% water exchange. The effects of increasing crop densities, from zero plants for the control, 0.035 ± 0.003 kg/m2 in Treatment 1, 0.029 ± 0.002 kg/m2 in Treatment 2, and 0.021 ± 0.003 kg/m2 in Treatment 3, were tested on the growth performance of C. gariepinus with an initial density of 3.00 ± 0.50 kg/m3. The specific growth rate (SGR), daily growth rate of fish (DGRf), and survival rate (SR) of the C. gariepinus were monitored. Nutrient removal, daily growth rate of plant (DGRp), relative growth rate (RGR), and the sum of leaf number (Æ©n) of the P. odorata plant were also recorded. It was found that nutrient removal percentage significantly increased with the presence of P. odorata at different densities. The growth performance of C. gariepinus was also affected by P. odorata density in each treatment. However, no significant difference was observed in the DGRp and RGR of the P. odorata (p>0.05), except for Æ©n values. Treatment 1 had the highest Æ©n number compared to Treatment 2 and Treatment 3, showing a significant difference (p<0.05). This study demonstrates that the presence of P. odorata significantly contributes to lower nutrient concentrations, supporting the fundamental idea that plants improve water quality in aquaponic systems.

Natural herbal extract roles and mechanisms in treating cerebral ischemia: A systematic review.

Background: Stroke has been the focus of medical research due to its serious consequences and sequelae. Among the tens of millions of new stroke patients every year, cerebral ischemia patients account for the vast majority. While cerebral ischemia drug research and development is still ongoing, most drugs are terminated at preclinical stages due to their unacceptable toxic side effects. In recent years, natural herbs have received considerable attention in the pharmaceutical research and development field due to their low toxicity levels. Numerous studies have shown that natural herbs exert actions that cannot be ignored when treating cerebral ischemia. Methods: We reviewed and summarized the therapeutic effects and mechanisms of different natural herbal extracts on cerebral ischemia to promote their application in this field. We used keywords such as "natural herbal extract," "herbal medicine," "Chinese herbal medicine" and "cerebral ischemia" to comprehensively search PubMed, ScienceDirect, ScienceNet, CNKI, and Wanfang databases, after which we conducted a detailed screening and review strategy. Results: We included 120 high-quality studies up to 10 January 2024. Natural herbal extracts had significant roles in cerebral ischemia treatments via several molecular mechanisms, such as improving regional blood flow disorders, protecting the blood-brain barrier, and inhibiting neuronal apoptosis, oxidative stress and inflammatory responses. Conclusion: Natural herbal extracts are represented by low toxicity and high curative effects, and will become indispensable therapeutic options in the cerebral ischemia treatment field.

Bio-active metabolites from Chinese Medicinal Herbs for treatment of skin diseases.

Skin diseases have become serious issues to human health and affect one-third of the world's population according to the World Health Organisation (WHO). These consist of internal (endogenous) and external (exogenous) factors referring to genetics, hormones, and the body's immune system, as well as environmental situations, UV radiation, or environmental pollution respectively. Generally, Western Medicines (WMs) are usually treated with topical creams or strong medications for skin diseases that help superficially, and often do not treat the root cause. The relief may be instant and strong, sometimes these medicines have adverse reactions that are too strong to be able and sustained over a long period, especially steroid drug type. Chinese Medicinal Herbs (CMHs) are natural resources and relatively mild in the treatment of both manifestation and the root cause of disease. Nowadays, CMHs are attractive to many scientists, especially in studying their formulations for the treatment of skin diseases. METHODS: The methodology of this review was searched in nine electronic databases including WanFang Data, PubMed, Science Direct, Scopus, Web of Science, Springer Link, SciFinder, and China National Knowledge Infrastructure (CNKI), without regard to language constraints. All eligible studies are analysed and summarised. RESULTS: Based on the literature findings, some extracts or active metabolites divided from CMHs, including Curcumin, Resveratrol, Liquorice, Dandelions, Cortex Moutan, and Calendula officinalis L., are effective for the treatment and prevention of skin diseases because of a wide range of pharmacological activities, e.g. anti-bacterial, anti-microbial, anti-virus, and anti-inflammation to enhance the body's immune system. It is also responsible for skin whitening to prevent pigmentation and premature ageing through several mechanisms, such as regulation or inhibition of nuclear factor kappa B (IκB/NF-κB) signalling pathways. CONCLUSION: This is possible to develop CMHs, such as Curcumin, Resveratrol, Liquorice, Dandelions, Cortex Moutan and Calendula officinalis L. The ratio of multiple CMH formulations and safety assessments on human skin diseases required studying to achieve better pharmacological activities. Nano formulations are the future investigation for CMHs to combat skin diseases.
