Meta-Analysis Review
BACKGROUND
The new coronavirus (COVID-19) has been transmitted exponentially. Numerous studies have been performed in recent years that have shown the inhibitory effect of plant extracts or plant-derived compounds on the coronavirus family. In this study, we want to use systematic review and meta-analysis to answer the question, which herbal compound has been more effective?
MAIN BODY
The present study is based on the guidelines for conducting meta-analyzes. An extensive search was conducted in the electronic database, and based on the inclusion and exclusion criteria, articles were selected and data screening was done. Quality control of articles was performed. Data analysis was carried out in STATA software.
CONCLUSION
Due to the variety of study methods, definitive conclusions are not possible. However, in this study, we attempted to gather all the available evidence on the effect of plant compounds on SARS-COV-2 to be used for the development and use of promising antiviral agents against this virus and other coronaviruses. Trypthantrin, Sambucus extract, S. cusia extract, Boceprevir and Indigole B, dioica agglutinin urtica had a good effect on reducing the virus titer. Also among the compounds that had the greatest effect on virus inhibition, Saikosaponins B2, SaikosaponinsD, SaikosaponinsA and Phillyrin, had an acceptable selectivity index greater than 10. Andrographolide showed the highest selectivity index on SARS-COV-2. Our study confirmed insufficient data to support alkaloid compounds against SARS-COV-2, and the small number of studies that used alkaloid compounds was a limitation. It is recommended to investigate the effect of more alkaloid compounds against Corona virus.

Review
Currently available treatment options for melasma include prevention of UV radiation, topical lightening agents, chemical peels, and light-based and laser therapies. However, none have shown effective and sustained results, with incomplete clearance and frequent recurrences. There has been increasing interest recently in oral medications and dietary supplements in improving melasma. We sought to evaluate the efficacy and safety/tolerability of oral medications and dietary supplements for the treatment of melasma. Multiple databases were systematically searched for randomized clinical trials (RCTs) evaluating the use of oral medication for treatment of melasma alone or in combination with other treatments. A total of eight RCTs met inclusion criteria. Oral medications and dietary supplements evaluated include tranexamic acid, Polypodium leucotomos extract, beta-carotenoid, melatonin, and procyanidin. These agents appear to have a beneficial effect on melasma improvement. In conclusion, oral medications have a role in melasma treatment and have been shown to be efficacious and tolerable with a minimal number and severity of adverse events. Therefore, dermatologists should keep oral medications and dietary supplements in their armamentarium for the treatment of melasma.

BACKGROUND
Poguntano () is a traditional herb commonly used as a blood glucose lowering agent in Indonesia. However, the effectiveness of the herb has not yet been established.
OBJECTIVE
This systematic review and meta-analysis aim to review the hypoglycemic effect of Poguntano extract in lowering plasma glucose levels.
METHODS
We conducted a literature search using peer-reviewed databases for relevant articles on Poguntano extract in animal models of diabetes. The effect size was pooled using a random effect model.
RESULTS
Two animal studies were included in the systematic review and meta-analysis. There was a significant difference in plasma glucose levels between diabetic control and rats treated with Puguntano extract (MD: 28.77; 95%CI: 6.20-51.34; p=0.01). There was no significant difference between non-diabetic control and Poguntano extract.
CONCLUSION
Poguntano extract lowers the blood glucose levels in diabetic rats compared to control.

Review
Essential oils are extensively used in the food, cosmetic, perfume, pharmaceutical, and agrochemical industries due to their aroma and pharmacological properties. The Lamiaceae family is mainly represented by widely well-known medicinal and aromatic plants that produce essential oil. Over the years, Sideritis L. essential oils have attracted great interest due to their chemical variability among the different taxa and their pharmacological activities. In-depth research of previously published literature was performed on electronic databases with several key search words for the collection of the available data and a total of 128 scientific studies were used since 1983. To date, 155 accepted Sideritis samples have been studied originating from 15 countries and more than 250 compounds have been reported in 87 Sideritis taxa overall. Furthermore, antimicrobial and antioxidant effects have been the most studied pharmacological activities. This review summarizes and critically discusses the research work on the chemical composition and pharmacological activities of essential oil of the genus Sideritis based on the currently valid taxonomy. Additionally, statistical analysis is encompassed to provide a deeper comprehensive understanding of the high chemical polymorphism of Sideritis essential oils. We expect that this review will encourage researchers to investigate unexplored Sideritis taxa and will contribute to revealing uncharted scientific territory and future perspectives on these plants.

Meta-Analysis
BACKGROUND
The objective of this meta-analysis was to review clinical trials of the combination of Pycnogenol ® and L-arginine (PAL) in the treatment of erectile dysfunction in men and to observe the effect of PAL combined therapy on sexual function in patients with erectile dysfunction (ED), and we hope to provide more choices of drugs for treating patients with ED.
METHODS AND ANALYSIS
The study was constructed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. We searched seven databases from inception to 15 February 2023, for a comprehensive search of clinical trials using relevant keywords. Continuous variables in this meta-analysis were calculated using the mean difference and 95% confidence interval. All relevant statistical analyses were performed using RevMan v. 5.4 software.
RESULTS
Three studies with 184 patients were included in the present meta-analysis. There were no significant differences in the basic characteristics of the included studies. The results of the current meta-analysis showed that there were significant differences in the international index of erectile function scores (erectile domain), intercourse satisfaction scores, orgasmic function scores, overall satisfaction scores, and sexual desire scores between the combination treatment group and the control group. There was no significant difference in improving the testosterone levels between the two groups.
CONCLUSION
These results indicate that the combination of PAL may have a significant effect on improving sexual function in patients with mild to moderate ED. This study will provide clinicians with more options for treating patients with ED. More randomized controlled trials are needed in the future to further demonstrate the effect of combination therapy on sexual function in patients with ED.

Review
In traditional Chinese medicine, Lonicerae Japonicae Flos is commonly used as anti-inflammatory, antiviral, and antipyretic herbal medicine, and geo-authentic herbs are believed to present the highest quality among all samples from different regions. To discuss the current situation and trend of geo-authentic Lonicerae Japonicae Flos, we searched Chinese Biomedicine Literature Database, Chinese Journal Full-text Database, Chinese Scientific Journal Full-text Database, Cochrane Central Register of Controlled Trials, Wanfang, and PubMed. We investigated all studies up to November 2015 pertaining to quality assessment, discrimination, pharmacological effects, planting or processing, or ecological system of geo-authentic Lonicerae Japonicae Flos. Sixty-five studies mainly discussing about chemical fingerprint, component analysis, planting and processing, discrimination between varieties, ecological system, pharmacological effects, and safety were systematically reviewed. By analyzing these studies, we found that the key points of geo-authentic Lonicerae Japonicae Flos research were quality and application. Further studies should focus on improving the quality by selecting the more superior of all varieties and evaluating clinical effectiveness.

Review
OBJECTIVE
Melanin gives some natural protection against the harmful effects of ultraviolet radiation; however, excessive production of melanin causes skin hyperpigmentation. Depigmenting cosmetics can be used to control this process; however, depigmenting agents commonly used have some disadvantages, such as low bioavailability, photosensitization, cellular toxicity, and insolubility. Natural sources of melanogenic inhibitors have become important alternatives to synthetic ones. The objective of this review was to summarize the results of studies on natural extracts that have been reported in the literature to inhibit the process of melanogenesis, giving a view on their suitability for potential use in new cosmetic formulations for skin-lightening.
DATA SOURCES
A systematic literature search was carried out using the descriptors: "melanogenesis", "tyrosinase", "tyrosinase inhibition", and "natural agents".
STUDY SELECTION
Publications were selected based on our designated inclusion and exclusion criteria, and a total of 15 studies met these criteria.
DATA EXTRACTION
The following were used in the review of each paper which met the criteria: the name of the plant (all of the natural extracts turned out to be from plants), the method used to obtain the plant extract, the method for evaluating anti-tyrosinase activity, the main results, and the conclusions.
DATA SYNTHESIS
All evaluated natural agents demonstrated anti-tyrosinase effect. The species Leathesia difformis, Morus alba, Orostachys japonicus, Heracleum moellendorffii, Coix lacryma-jobi (adlay), Inula brittanica, and Gailardia aristata stood out from the others due to their application as potential inhibitors of more than three proteins related to melanogenesis, including the cyclic adenosine monophosphate response element-binding protein, microphthalmia-associated transcription factor, tyrosinase, tyrosinase-related protein-1, tyrosinase-related protein-2, and dopachrome tautomerase.
CONCLUSION
The plants present an anti-tyrosinase effect that must be better explored in the new cosmetic formulations. The anti-melanogenic effects of the plant are mainly related to the presence of phenolic and antioxidant compounds.

Review
The aging process predisposes numerous homeostatic disorders, metabolic disorders, cardiovascular diseases, neurodegenerative diseases, and cancer. Changes in diet and lifestyle and therapeutic adjuvants are essential to minimize the effects of comorbidities associated with aging. Natural products such as Panax ginseng have been used to treat and prevent diseases related to aging. This review aims to investigate the effects of Panax ginseng in various conditions associated with aging, such as inflammation, oxidative stress, mitochondrial dysfunction, apoptosis, neurodegenerative and metabolic disorders, cardiovascular diseases, and cancer. The ginsenosides, chemical constituents found in Panax ginseng, can inhibit the effects of inflammatory cytokines, inhibit signaling pathways that induce inflammation, and inhibit cells that participate in inflammatory processes. Besides, ginsenosides are involved in neuroprotective effects on the central nervous system due to anti-apoptotic, antioxidant, and anti-inflammatory effects. The use of ginseng extract showed actions on lipid homeostasis, positively regulating high-density lipoprotein, down-regulating low-density lipoprotein and triglyceride levels, and producing beneficial effects on vascular endothelial function. The use of this plant in cancer resulted in improved quality of life and mood. It decreased symptoms of fatigue, nausea, vomiting, and dyspnea, reducing anxiety. Panax ginseng has been shown to exert potent therapeutic benefits that can act as a complementary treatment in managing patients with chronic diseases related to aging.

Review
BACKGROUND
Post-thrombotic syndrome (PTS) is a long-term complication of deep venous thrombosis (DVT) that is characterised by pain, swelling, and skin changes in the affected limb. One in three patients with DVT will develop post-thrombotic sequelae within five years. The current standard care for the prevention of PTS following DVT is elastic compression stockings. Rutosides are a group of compounds derived from horse chestnut (Aesculus hippocastanum), a traditional herbal remedy for treating oedema formation in chronic venous insufficiency (CVI). However, it is not known whether rutosides are effective and safe in the prevention of post-thrombotic syndrome. This is an update of the review first published in 2013.
OBJECTIVES
To determine the effectiveness and safety of rutosides for prevention of PTS in patients with DVT, compared to placebo, no intervention, or reference medication.
SEARCH METHODS
For this update the Cochrane Vascular Group Trials Search Co-ordinator searched the Specialised Register (last searched September 2015) and the Cochrane Register of Studies (CRS) ((CENTRAL) 2015, Issue 8). Clinical trials databases were searched for details of ongoing and unpublished studies.
SELECTION CRITERIA
We planned to include trials of rutosides versus any alternative (placebo, no intervention, or reference medication) in the prevention of PTS in patients with DVT.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed studies for inclusion and intended to extract information from the trials.
MAIN RESULTS
No studies were identified comparing rutosides versus any alternative in the prevention of PTS.
AUTHORS' CONCLUSIONS
As there were no studies identified in this review there is currently insufficient evidence to determine the effectiveness and safety of rutosides for prevention of PTS in patients with DVT. Some studies suggest that rutosides may provide short-term relief of PTS symptoms. However, there is nothing published on their use as a preventative therapy for PTS. High quality randomised controlled trials of rutoside versus any alternative are required to build the evidence base in this area.

Meta-Analysis Review
ETHNOPHARMACOLOGICAL RELEVANCE
Salvadora persica L., also known as miswak, is an indigenous plant most prevalent in the Middle Eastern, some Asian, and African countries. It has medicinal and prophylactics function for numerous illnesses, including periodontal disease. Various trials, apart from World Health Organization encouragement have contributed to the production and use of S. persica in extract form in the formulation of mouthwash. This systematic review and meta-analysis aimed to compare the clinical effect of Salvadora persica-extract mouthwash and chlorhexidine gluconate mouthwash for anti-plaque and anti-gingivitis functions.
METHODS
Using the PRISMA 2020 Protocol, a systematic search of the publications was undertaken from the MEDLINE, CENTRAL, Science Direct, PubMed, and Google Scholars for randomized control trials published through 31st January 2022 to determine the effectiveness of Salvadora persica-extract mouthwash relative to chlorhexidine gluconate as anti-plaque and anti-gingivitis properties.
RESULTS
A total of 1809 titles and abstracts were screened. Of these, twenty-two studies met the inclusion criteria for the systematic review while only sixteen were selected for meta-analysis. The overall effects of standardized mean difference and 95% CI were 0.89 [95% CI 0.09 to 1.69] with a χ statistic of 2.54, 15 degrees of freedom (p < 0.00001), I = 97% as anti-plaque function and 95% CI were 0.12 [95% CI -0.43 to 0.67] with a χ statistic of 0.68 with 10 degree of freedom (p < 0.00001), I = 89% as anti-gingivitis.
CONCLUSION
This review suggests that Salvadora persica-extract mouthwash causes a significant reduction of plaque and gingival inflammation. While the improvement is inferior to chlorhexidine gluconate mouthwash, S. persica-extract mouthwash may be considered as a herbal alternative to the user pursuing periodontal care with natural ingredients.
