Standardizing traditional herbal formulations poses significant challenges due to inherent variability in plant sources, environmental conditions, and processing methods. This narrative review explores how metabolomics a powerful high-throughput analytical approach for comprehensive chemical profiling addresses these issues by enabling the identification and quantification of bioactive compounds in complex herbal mixtures. Advanced analytical tools such as nuclear magnetic resonance (NMR), liquid chromatography–mass spectrometry (LC-MS), and gas chromatography–mass spectrometry (GC-MS) provide detailed metabolic fingerprints that underpin quality control and therapeutic consistency. Emerging techniques including desorption electrospray ionization–mass spectrometry (DESI-MS), direct analysis in real-time mass spectrometry (DART-MS), single-cell metabolomics, and stable isotope ratio analysis (SIRA) enhance spatial and geographical specificity, offering rapid and minimally invasive profiling capabilities. Integration of metabolomics with chemometric tools such as principal component analysis (PCA) and partial least squares–discriminant analysis (PLS-DA), facilitates authentication and batch-to-batch consistency. Furthermore, artificial intelligence (AI) and machine learning (ML) algorithms are increasingly employed to automate metabolite identification, predict pharmacological properties, and accelerate biomarker discovery. These advances collectively support evidence-based standardization and sustainability of herbal medicines, contributing to global healthcare integration. Key outcomes of this review include: identification of metabolomics as a cornerstone for quality assurance and authenticity of herbal products, evaluation of emerging analytical platforms for improving formulation reproducibility, and recommendations for interdisciplinary collaboration and regulatory alignment. Literature included in this study was sourced from peer-reviewed articles published over the past decade in databases such as PubMed, Scopus, and Web of Science. Overall, the review underscores the pivotal role of metabolomics in transforming traditional herbal practices into standardized, scalable, and personalized therapeutic interventions.

Sickle cell anemia (SCA) is a hereditary blood disorder characterized by the presence of abnormal hemoglobin, leading to the formation of sickle-shaped red blood cells. While much research has focused on the molecular and cellular mechanisms underlying the pathophysiology of SCA, recent attention has turned to the role of apoptosis, or programmed cell death, in the disease progression. This review aims to elucidate the intricate mechanisms of apoptosis in SCA patients and explore its implications in disease severity, complications, and potential therapeutic interventions. Different research search engines such as PubMed central, Scopus, Web of Science, Google Scholar, ResearchGate, Academia Edu, etc were utilized in writing this paper. Apoptosis, a highly regulated cellular process, plays a crucial role in maintaining homeostasis by eliminating damaged or dysfunctional cells. In SCA, the imbalance between pro-apoptotic and anti-apoptotic signals contributes to increased erythrocyte apoptosis, exacerbating anemia and vaso-occlusive crises. Various factors, including oxidative stress, inflammation, and altered cell signaling pathways, converge to modulate the apoptotic response in SCA. Furthermore, the interaction between apoptotic cells and the vascular endothelium contributes to endothelial dysfunction, promoting the pathogenesis of vasculopathy and organ damage seen in SCA patients. In conclusion, unraveling the complexities of apoptosis in SCA provides valuable insights into the disease pathophysiology and offers novel avenues for therapeutic interventions.

Diabetes mellitus is a long-term metabolic condition marked by chronically high levels of glucose in the blood due to insufficient synthesis of insulin or impaired insulin function. Throughout history, several civilizations have used traditional medicinal plants to treat and control diabetes. This paper offers a thorough review, to date, of the antidiabetic natural compounds of medicinal plants origin, specifically highlighting their reported modes or mechanisms of action and therapeutic possibilities, with a view to fast-tracking the possibility of their transition to pharmaceutical products for human use. Phytochemicals such as flavonoids, alkaloids, terpenoids, and glycosides have notable antidiabetic effects. They have been shown to control blood glucose levels via many processes, including boosting insulin secretion, improving insulin sensitivity, blocking glucose absorption in the \gastrointestinal-tract, and regulating carbohydrate metabolism. Unlike earlier reviews, this current one, in addition to the chemistry and proposed mechanisms of action, also x-rays the effectiveness and safety of these natural chemicals by combining evidences from laboratory research, animal experiments, and clinical trials. Several substances, such as Demethoxycurcumin, Trigonelline, and Ginsenosides, have progressed to clinical trials, while others like Allicin and Polypeptide-p have been used at the bedside. Several substances, including Bisdemethoxycurcumin, Vicine, and Gymnemosides, are now in the preclinical trial phase, suggesting that research is still ongoing and there is promise for their future medicinal application. The review highlights the evolution of chemicals in diabetes management, highlighting their potential to improve treatment. It suggests incorporating plant-derived compounds into traditional treatments, reducing dependence on drugs and reducing adverse effects.

Pregnancy leads to a number of structural and functional changes in the urinary system, which makes females susceptible to urological complications. This review aims to discuss the epidemiology, complications and prevention and management of urinary tract infections (UTIs), kidney stones and bladder dysfunction in pregnancy. UTIs are the most common urological problem presenting in 10% of pregnant women; Escherichia coli is the most common causative organism. If left untreated, UTIs lead to acute pyelonephritis which occurs in about 2% of pregnant women and which has serious consequences for both the mother and the baby. Kidney stones, although rare, are hazardous, occurring in 1 in 200 to 1 in 1500 pregnancies, and may cause obstructive uropathy, and aggravation of “labor-like” pain. Urological complications are frequent in pregnancy; bladder dysfunction alone has been documented to affect 50% of the pregnant women. Urological complications can have severe consequences when not properly managed including preterm labor and renal dysfunction. In order to have the best pharmacological care, safe use of antibiotics for UTIs is needed along with other measures for kidney stones. This review highlights the importance of a team approach to patient management to optimize outcome and touches briefly on some of the ethical dilemmas that may be encountered when drug therapy in pregnancy is being considered. Therefore, it is feasible to enhance the health of women and the fetus during this period through patient focused care and innovative interventions.

Plant secondary metabolites (PSMs) are vital bioactive compounds with wide pharmaceutical, agricultural, and industrial applications. However, their commercial production faces challenges due to low yields, environmental variability, and high extraction costs. Endophytes, microorganisms living within plant tissues, have emerged as key regulators of plant metabolism, enhancing PSM production through activation of biosynthetic gene clusters, secretion of precursor molecules, and modulation of plant stress responses. This narrative review explores recent advances in understanding endophyte-plant interactions, focusing on their mechanisms for stimulating metabolite production. It highlights biotechnological applications, including metabolic engineering, genome editing, and co-cultivation strategies, for optimizing endophyte-mediated biosynthesis. The review also identifies challenges in large-scale application and proposes recommendations for integrating endophytes into sustainable agriculture and pharmaceutical production. Harnessing endophytes offers an eco-friendly, cost-effective approach for scalable natural product biosynthesis, with significant potential for addressing global health, agricultural sustainability, and industrial needs.
