Abstract

Introduction

Mitochondria are cell organelles that function as the cell’s main power plant, producing ATP, the main energy molecule in cells. Mitochondria play an important role in the context of neuroprotection, and mitochondrial function has been implicated in various neurodegenerative diseases, including Alzheimer’s, Parkinson’s, and amyotrophic lateral sclerosis (ALS). Recent research in the field of neuroprotection has focused on the development of therapies that target mitochondria. Natural ingredients have long been used in traditional medicine and show potential as neuroprotective agents.

Methods

In this work, a literature review methodology is employed to gather data from the Scopus database using the keywords natural agents, herb*, neuroprotective, and mitochondria. The data were analyzed using Biblioshiny and VOSviewer software to produce visualizations and bibliometric maps. We conducted quantitative and qualitative analyses.

Results

The research trend found are documents by year, most global cited document, most relevant sources, A factorial map illustrating the leading contributors of papers, documents by author, documents by country or territory, documents by subject area, network visualization, overlay visualization of scopus database using vosviewer, density visualization, thematic map, thematic evolution, cluster analysis, qualitative analysis, and word cloud.

Conclusions

Natural Agent Neurotropik is a natural substance that influences the brain’s nervous system and peripheral nervous system, enhancing cognition, mood, and brain function. Derived from herbs, spices, and herbal products, it has advantages over other natural agents in energy production, brain biogenesis, and neuroprotection. Natural agents’ compositional heterogeneity affects reproductive results. Proper characterization and standardized extraction techniques are crucial for establishing plant extracts’ chemical profile. Dosage consistency is essential for standardized results. Long-term safety and potential toxicity should be evaluated. Comparing natural medicines with synthetic pharmaceuticals can enhance therapy efficacy and reduce drug resistance. Further research is needed to assess neuroprotection and mitochondrial function.

Introduction

Mitochondria are cell organelles that function as the cell’s main power plants, producing ATP, the main energy molecule in cells. Mitochondria also play a role in various other processes such as the citric acid cycle, fatty acid oxidation, and amino acid metabolism. Therefore, mitochondria are essential for the normal functioning of cells and the organism as a whole.

In the context of neuroprotection, mitochondria play a very important role. Impaired mitochondrial function has been linked to a variety of neurodegenerative diseases, including Alzheimer’s, Parkinson’s, and amyotrophic lateral sclerosis (ALS).1 Therefore, recent research in the field of neuroprotection has focused on the development of therapies targeting mitochondria.1

Natural ingredients have long been used in traditional medicine and have shown potential as neuroprotective agents.1 Several natural substances have been shown to have neuroprotective effects, either through improving mitochondrial function or through other mechanisms1. Several natural substances have been shown to have neuroprotective effects, either through improving mitochondrial function or through other mechanisms.1

Another advantage of natural substances is that they are often cheaper and more accessible compared to synthetic drugs. Additionally, natural ingredients often have fewer side effects, making them a better choice for many patients. However, more research is needed to fully understand how these natural ingredients work and how they can be used in the most effective way.1

Overall, research on the importance of mitochondria in neuroprotection and the potential of natural products as neuroprotective agents is a very promising area. With more research, we can develop new, more effective, and more efficient therapies for neurodegenerative diseases.

Natural agents have compositional heterogeneity that can influence reproductive results across several studies. Consequently, it is essential to conduct adequate characterization and employ standardized extraction techniques. Precise characterisation entails identifying active components and establishing the chemical profile of plant extracts. Chromatographic techniques, such as *High-Performance Liquid Chromatography (HPLC)* and *Gas Chromatography (GC), can be employed to identify and quantify active chemicals in plant extracts. Furthermore, spectroscopic techniques such as *Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) Spectroscopy are applicable for the characterization of substances.

Conventional extraction techniques, including maceration, percolation, and Soxhlet extraction, must be employed to guarantee uniformity in the extract’s composition. Maceration entails immersing plant material in a solvent at ambient temperature, whereas percolation consists of the solvent traversing through the plant material. Soxhlet extraction use hot solvent to isolate active chemicals from plant material. Employing a standardized extraction procedure will guarantee that the resultant extract possesses a homogeneous composition.

Furthermore, dose consistency is crucial to guarantee that the doses employed in research are standardized and replicable. Inconsistent dosing may result in disparate outcomes and complicate the comparison of findings across several research. Consequently, it is essential to ascertain the suitable dosage based on prior preclinical and clinical studies.

The long-term safety and potential toxicity of natural agents should be evaluated, particularly when administered in elevated doses or over prolonged durations. Certain natural substances may exhibit adverse side effects or toxicity when administered in elevated concentrations. Certain natural chemicals may induce hepatic or renal damage when administered in high quantities. Consequently, it is essential to undertake additional study to assess the long-term safety of these natural agents.

Data from toxicological studies and clinical trials can yield more extensive insights into the potential risks and advantages of utilizing natural substances. Toxicology study entails the examination of chemicals on laboratory animals to ascertain safe dosage levels and those that induce hazardous effects. Clinical studies entail the assessment of substances on human subjects to determine their safety and efficacy. This research provides data to establish a safe and effective dosage for prolonged use.

An analysis comparing the performance of natural medicines with synthetic pharmaceuticals regarding neuroprotection and mitochondrial function helps elucidate the benefits and drawbacks of natural therapy. Natural agents typically have a superior safety profile and a reduced incidence of side effects in comparison to synthetic pharmaceuticals. Natural substances like curcumin and resveratrol exhibit neuroprotective properties with little adverse consequences. Nevertheless, synthetic medications such as memantine and ketamine may exhibit more success in the treatment of neurodegenerative illnesses; yet, they may also result in more severe adverse effects.

Comparative investigations utilizing in vitro and in vivo methodologies can yield profound insights into the distinctions between natural medicines and synthetic pharmaceuticals regarding neuroprotection and mitochondrial function. In vitro tests entail evaluating chemicals on cells produced in a laboratory setting, whereas in vivo tests involve assessing compounds on laboratory animals. This study’s results can identify the merits and demerits of each therapy kind.

The integration of natural agents with synthetic pharmaceuticals can offer a more comprehensive and efficacious strategy for neuroprotection and mitochondrial function. This combination can utilize the benefits of both agent types, specifically the superior safety profile of natural agents and the enhanced efficacy of synthetic medications. The combination of curcumin and memantine can augment neuroprotective effects by mitigating the adverse effects associated with the use of memantine in isolation.
