Consumption and adverse reaction reporting of herbal medicines among people living with HIV at University teaching hospitals in Blantyre, Malawi and Ibadan, Nigeria.

Background: Consumption of herbal medicines among people living with HIV is a common practice in Sub-Saharan Africa. The utilization of herbal medicines was at 17.5% and 67.9% in Malawi and Nigeria, respectively. There is inadequate data on use and adverse reactions (ADRs) reporting of herbal medicines among people living with HIV (PLWHIV). This study was designed to investigate use and ADRs reporting of herbal medicines among PLWHIV at the University Teaching Hospitals in Blantyre, Malawi and Ibadan, Nigeria. Methodology: A cross-sectional study was conducted among PLWHIV attending Antiretroviral Therapy (ART) clinic at Queen Elizabeth Central Hospital, Blantyre, Malawi and University College Hospital, Ibadan, Nigeria. A structured questionnaire was administered to 360 and 370 participants in Blantyre and Ibadan respectively, through face-to-face interviews after obtaining their informed consent. Results: The prevalence of herbal medicines use among PLWHIV in Malawi and Nigeria was at 80.6% and 55.7% (p<0.001), respectively. The most frequently used herbal medicines in Malawi were Aloe vera (14.0%), Moringa oleifera (14.0%), Zingiber officinale (13.0%) and Allium sativum (7.0%). Likewise, in Nigeria, the most commonly used herbal medicines were Zingiber officinale (15.0%), Vernonia amygdalina (14.0%), Moringa oleifera (9.0%), and Allium sativum (11.0%). The major reason for herbal medicines' use in Malawi was ready availability (42.1%) and perception that it boosts immunity (44.6%) in Nigeria. The PLWHIV reported experiencing suspected herbal medicine ADRs in Malawi (3.9%) and in Nigeria (8.0%). Conclusion: A higher percentage of people living with HIV are using herbal medicines in Malawi as well as in Nigeria. In both countries, a few participants reported experiencing suspected ADRs related to herbal medicines.

Ethnobotanical study of medicinal plants used to treat human ailments in Quara district, northwestern Ethiopia.

BACKGROUND: Ethiopia is recognized as one of the centers of origin for the diversity of many plant species, including medicinal plants. Throughout the country, a large proportion of the population relies on these therapeutic plant species for primary healthcare. While such traditional medicinal knowledge has been documented in some regions, there is a lack of information from the Quara district of northwestern Ethiopia. Therefore, this study aimed to document the indigenous and local knowledge of the use of medicinal plants among three ethnic groups residing in the area. METHODOLOGY: An ethnobotanical study was conducted from August 2022 to October 2023 in ten kebeles of the Quara district. Data were collected through semi-structured interviews, field walks, and focus group discussions with 286 informants using snowball, purposive, and random sampling techniques. Quantitative analyses included Rahman's similarity index (RSI), informant consensus factor (ICF), and direct matrix ranking (DMR). Descriptive statistics were used to analyze basic ethnobotanical data. RESULTS: A total of 128 medicinal plant species from 112 genera and 50 families were documented and used to treat 14 disease categories. There was a 28% overlap in medicinal plant knowledge among the three ethnic groups studied. Fabaceae was the most represented family with 22 species. Trees accounted for the majority of the documented plants (37.5%), and leaves were the most commonly used plant parts (23.1%). Oral administration (56.7%) of plant extracts was the primary mode of remedy preparation and use. The highest ICF value (0.93) was recorded for circulatory and blood-related disorders. The study identified nine plants and 39 therapeutic uses not previously reported in Ethiopia. The RSI showed high overlap with neighboring areas and low similarity with distant areas. Top-ranked multipurpose plants were Ziziphus spina-christi and Terminalia leiocarpa, with agricultural expansion and fuelwood collection identified as major threats. CONCLUSION: The findings demonstrate the rich diversity of medicinal plants and associated traditional knowledge in the Quara district. The high ethnobotanical indices warrant further phytochemical and pharmacological investigations. Integrated conservation efforts are recommended to address the challenges facing these valuable plant resources.

Farmers' knowledge in the Swiss canton Valais: cultural heritage with future significance for European veterinary medicine?

BACKGROUND: The demand for natural product-based treatment options for livestock is increasing by animals' owners, veterinarians and policy makers. But at the same time, the traditional knowledge about it is at risk of falling into oblivion in Europe. The present study recorded this knowledge for the linguistically and geographically interesting Swiss canton of Valais. METHOD: Open, semi-structured interviews were used to collect detailed information on formulations and applications, including plant species and natural substances, origin of material, extraction and preparation of herbal products, indication and type of application, dosage, sources of knowledge, frequency of usage and self-assessment of the treatment. RESULTS AND DISCUSSION: In the course of 43 interviews, 173 homemade single species herbal remedy report (HSHR) were recorded. They included 53 plant species from 30 botanical families. Plant species from the botanical families of Asteraceae, Rubiaceae and Cupressaceae were mentioned the most, while the most frequently documented plant species were Coffea arabica L., Juniperus sabina L., Arnica montana L. and Matricaria chamomilla L. For the 173 HSHR, a total of 215 uses were mentioned, most of which were for the treatment of gastrointestinal and metabolic disorders, followed by skin lesions and genito-urinary tract problems. Regional peculiarities emerged, such as the use of Leontopodium alpinum Cass. for diarrhea in the French-speaking Valais, while Matricaria chamomilla and Camellia sinensis L. were used in the German-speaking part instead. In comparison with other regions of Switzerland, 10 plants were reported for the first time, including Juniperus sabina with 18 use reports. CONCLUSION: The daily use on farms and the high satisfaction of farmers with homemade herbal remedies demonstrate their high practical relevance. In conclusion, the traditional regional knowledge about the use of medicinal plants is not only a cultural heritage worth protecting, but also an essential resource for the further development of European veterinary medicine.

A Comprehensive Review of Traditional Medicinal Uses, Geographical Distribution, Botanical Characterization, Phytochemistry, and Pharmacology of Aralia continentalis Kitag.

Aralia continentalis Kitag. (A. continentalis) holds significant medicinal value among the Aralia genus. It has traditionally been employed in ethnomedicine to address a wide range of conditions, including wind-cold-dampness arthralgia; rheumatic pain in the waist and lower extremities; lumbar muscular strain; injuries resulting from falls, fractures, contusions, and strains; headache; toothache; and abscesses. Modern pharmacological research has validated its therapeutic potential, encompassing anti-inflammatory, analgesic, antioxidant, antimicrobial, insecticidal, hepatoprotective, anti-diabetic, and cytotoxic properties, among other pharmacological effects. To compile comprehensive knowledge on A. continentalis, a rigorous literature search was undertaken utilizing databases like SciFinder, PubMed, and Web of Science. This review seeks to delve into the plant's traditional applications, geographical distribution, botanical characteristics, phytochemistry, and pharmacology. The objective is to lay a foundation and propose novel research directions for exploring the plant's potential applications. Currently, one hundred and fifty-nine compounds have been isolated and identified from A. continentalis, encompassing diterpenoids, steroids, triterpenoids, volatile components, phenolics, vitamins, trace elements, and other compounds. Notably, diterpenoids, steroids, triterpenoids, volatile components, and phenolics have exhibited pronounced pharmacological effects, such as anti-inflammatory, analgesic, antioxidant, hepatoprotective, antidiabetic, and antimicrobial activities. However, despite the extensive research conducted, further studies are imperative to unravel new components and mechanisms of action, necessitating more in-depth investigations. This comprehensive exploration could pave the way for advancing and harnessing the potential of A. continentalis.

The prevalence of herbal medicine among Sudanese adults: a cross-sectional study 2021.

BACKGROUND: The use of herbal medicine has a long history in Sudan and is widely practiced among the general population. However, there is a lack of studies examining the prevalence, patterns, and predictors of herbal medicine usage in Sudan. Thus, this study was conducted to bridge this gap. METHODS: This descriptive cross-sectional study was conducted between January and February 2021. It included Sudanese adults residing in Omdurman, Sudan, using systematic and simple random sampling methods. Data were collected using a structured, adapted questionnaire comprising: the socio-demographic characteristics and the knowledge of herbal medicine and its usage. Moreover, it investigated the commonly used herbal remedies and the participants' sources of information and procurement of such products. Additionally, we examined the correlation between socio-demographic factors, cultural beliefs, and the use of herbal medicine. Data were analyzed using SPSS, and categorical data were presented as frequencies and percentages. Associations were assessed using chi-square, Fisher's exact tests, and binary logistic regression (p < 0.05). RESULTS: This study included 381 participants, of which 48.1% were females and 31.4% were aged 20-30. The majority of participants were aware of the practice of herbal medicine and the prevalence of its usage was 85.9%. Peppermint, acacia, hibiscus, ginger, and fenugreek were the most commonly used remedies. Chi-square and Fisher's exact testing revealed that the participants' gender and beliefs in the safety and effectiveness of herbal medicines were significantly associated with herbal medicine usage (p < 0.05). Binary logistic regression analysis showed that only the perception of herbal medicine's safety was an independent predictor of its usage (p-value 0.038). CONCLUSION: This study reported a very high prevalence of herbal medicine usage, highlighting the acceptability of Sudanese adults towards herbal medicine usage. This prompts further studies to explore their safety, efficacy, and the possibility of their integration into mainstream healthcare practices and policies.

Ageratum conyzoides Extract Ameliorates Testosterone-Induced Benign Prostatic Hyperplasia via Inhibiting Proliferation, Inflammation of Prostates, and Induction of Apoptosis in Rats.

Ageratum conyzoides, an annual herbaceous plant that inhabits tropical and subtropical regions, has been traditionally used in Asia, Africa, and South America for phytotherapy to treat infectious and inflammatory conditions. However, the pharmacological effects of standardized ethanolic extract of Ageratum conyzoides (ACE) on benign prostatic hyperplasia (BPH) remain unexplored. The objective of this research is to examine the potential physiological impacts of ACE, a traditionally utilized remedy for inflammatory ailments, in a rat model with BPH induced by testosterone propionate (TP). Rats were subcutaneously administered TP (3 mg/kg) to induce BPH and concurrently orally administered ACE (20, 50, and 100 mg/kg) daily for 42 days. ACE markedly improved BPH characteristics, including prostate weight, prostate index, and epithelial thickness, while also suppressing androgens and related hormones. The findings were supported by a decrease in androgen receptor and downstream signals associated with BPH in the prostate tissues of the ACE groups. Furthermore, increased apoptotic signals were observed in the prostate tissue of the ACE groups, along with heightened detection of the apoptotic nucleus compared to the BPH alone group. These changes seen in the group that received finasteride were similar to those observed in this group. These findings suggest that ACE shows promise as an alternative phytotherapeutic agent for treating BPH.

Saffron as a Promising Therapy for Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) is a chronic inflammatory illness of the gastrointestinal tract (GI), characterized by recurrent episodes of inflammation and tissue destruction. It affects an increasing number of individuals worldwide who suffer from Crohn's disease (CD) or ulcerative colitis (UC). Despite substantial advances in understanding the underlying causes of IBD, the available treatments remain restricted and are sometimes accompanied by severe consequences. Consequently, there is an urgent need to study alternate therapeutic options. This review assesses the present drugs, identifies their limitations, and proposes the use of saffron, a natural plant with great therapeutic potential based on preclinical and clinical investigations. Saffron has gained attention for its potential therapeutic benefits in treating various ailments due to its established bioactive compounds possessing antioxidant and anti-inflammatory properties. This review covers how saffron impacts the levels of calprotectin, an inflammatory marker, for various inflammatory responses in multiple diseases including IBD. Data from clinical trials were assessed to determine the efficacy and safety of using saffron to counter inflammation in multiple diseases. Studies have shown that saffron may protect against inflammatory bowel disease (IBD) through several mechanisms by inhibiting pro-inflammatory cytokines (TNF-α, IL-1ß, and IL-6), reducing oxidative stress through antioxidant effects, enhancing mucosal barrier function by upregulating tight junction proteins, and modulating the gut microbiota composition to promote beneficial bacteria while suppressing pathogenic ones; these combined actions contribute to its therapeutic potential in managing and alleviating the symptoms of IBD. This will enable future research endeavors and expedite the translation of saffron-based interventions into clinical practice as a valuable adjunctive therapy or a potential alternative to conventional treatments, thereby enhancing the quality of life for individuals suffering from inflammatory diseases including IBD.

From nature's bounty to drug discovery: Leveraging phytochemicals and molecular approaches to combat multi-drug-resistant (MDR) tuberculosis.

A large number of people annually lose their lives to tuberculosis (TB), which is an age-old disease caused by the Mycobacterium tuberculosis. The global spread of TB is a concern for all regions. The south-east Asian region recorded 46% of all new TB cases in 2021, followed by the African and western Pacific regions with 23% and 18%, respectively. Researchers are always searching at natural substances for potential alternative therapeutics to tackle the worrisome growth in multi-drug-resistant (MDR) tuberculosis due to the high costs associated with developing new treatments and unfavourable side effects of currently used synthetic pharmaceuticals. Phytochemicals show promising results as a future health aid due to their multi-targeting ability on pathogen cells. In the search for new drug leads, the Ayurvedic and Siddha medical systems have made an extensive use of ethnomedicinal tools, including the use of plants like Amalaki (Emblica officinalis Gaertn.), Guduchi (Tinospora cordifolia willd.), Sariva (Hemidesmus indicus R.Br.), Kustha (Saussurea lappa Falc.), turmeric (Curcuma longa Mal.) and Green tea (Camellia sinensis Linn.). These sources are high in flavonoids, polyphenols, tannins and catechins, has been shown to reduce the risk of TB. In this overview, we look at how natural sources like plants, algae and mushrooms have helped researchers to find new drug leads, and how to back these natural sources through mapping the molecular approaches and other approaches has helped them to defeat MDR.

Phytoconstituents as modulators of NF-κB signalling: Investigating therapeutic potential for diabetic wound healing.

The NF-κB pathway plays a pivotal role in impeding the diabetic wound healing process, contributing to prolonged inflammation, diminished angiogenesis, and reduced proliferation. In contrast to modern synthetic therapies, naturally occurring phytoconstituents are well-studied inhibitors of the NF-κB pathway that are now attracting increased attention in the context of diabetic wound healing because of lower toxicity, better safety and efficacy, and cost-effectiveness. This study explores recent research on phytoconstituent-based therapies and delve into their action mechanisms targeting the NF-κB pathway and potential for assisting effective healing of diabetic wounds. For this purpose, we have carried out surveys of recent literature and analyzed studies from prominent databases such as Science Direct, Scopus, PubMed, Google Scholar, EMBASE, and Web of Science. The classification of phytoconstituents into various categorie such as: alkaloids, triterpenoids, phenolics, polyphenols, flavonoids, monoterpene glycosides, naphthoquinones and tocopherols. Noteworthy phytoconstituents, including Neferine, Plumbagin, Boswellic acid, Genistein, Luteolin, Kirenol, Rutin, Vicenin-2, Gamma-tocopherol, Icariin, Resveratrol, Mangiferin, Betulinic acid, Berberine, Syringic acid, Gallocatechin, Curcumin, Loureirin-A, Loureirin-B, Lupeol, Paeoniflorin, and Puerarin emerge from these studies as promising agents for diabetic wound healing through the inhibition of the NF-κB pathway. Extensive research on various phytoconstituents has revealed how they modulate signalling pathways, including NF-κB, studies that demonstrate the potential for development of therapeutic phytoconstituents to assist healing of chronic diabetic wounds.

Medicinal plants used in multiple sclerosis patients, prevalence and associated factors: a descriptive cross-sectional study.

INTRODUCTION: Multiple sclerosis (MS) is a chronic and debilitating disease that not only leads to disability and associated condition but also impacts one's ability to maintain a professional life. People's acceptance and utilization of medicinal plants (MPs) play an important role in managing their treatment process. As a result, this study aims to investigate the use of medicinal herbs among patients with MS. METHODS: A descriptive cross-sectional study was conducted on 150 MS patients who visited a private clinic and the MS Association in Kerman, Iran in 2021. A questionnaire comprising questions about sociodemographic information, disease variables, and aspects of MPs usage was utilized for data collection. Statistical analysis was performed using SPSS version 20 (SPSS Inc., Chicago, IL). The Chi-square test was employed to identify any association between demographic characteristics and MPs usage. To determine the prevalence of plant use in a specific area and the consensus among informants, the use value (UV) and Informant consensus factor (Fic) were calculated. RESULTS: The study revealed a high prevalence of MPs usage among MS patients. Chamomile (66.6%) and golegavzaban (62.0%) were the most commonly used plants with the highest UV indices (0.88 and 0.82 respectively), while St. John's wort and licorice were rarely used (0.67% and 4% respectively). Participants cited pursuing a healthier lifestyle as the primary reason for using MPs (24%). St. John's wort, lavender, and chamomile were the most satisfying plants (100%, 100%, and 53.0% respectively). Chamomile had the highest Fic too. Most patients were motivated to get MPs from their relatives. CONCLUSIONS: Given the widespread use of MPs among MS patients, neurologists should enhance their knowledge in this area to guide patients away from seeking advice from non-professionals. Providing standardized formulations can help prevent potential interactions between MPs and mainstream drugs, thereby improving patients safety and outcomes.

Systematic Review of Randomized Controlled Trials in Uses of Nigella Sativa (Black Seed) in Metabolic Syndrome.

BACKGROUND: Metabolic syndrome as defined by The National Cholesterol Education Panel-Adult Treatment Panel III (NCEPATP III), is the presence of obesity, dyslipidaemia, the elevation of arterial blood pressure, and glucose intolerance. It affects 25% to 40% of the adult population of Malaysia and is associated with other medical conditions, especially cardiovascular disease. In this systematic review, the objective is to assess the effects of Nigella Sativa on parameters that reflect metabolic syndromes, such as lipid profile, blood pressure, blood glucose, and anthropometry indices. METHODS: This systematic review was conducted by performing searches for relevant publications on two databases (PubMed and Scopus). The publication period was limited from January 2011 to December 2021. Cochrane collaboration tools were used for the risk of bias assessment of each trial. RESULT: Six out of 8 randomised controlled trials (n:776) demonstrated a significant improvement in lipid profile (p <0.05), 5 out of 7 trials (n:701) showed a significant reduction in glycaemic indices (p <0.05), 1 out of 5 trials (n:551) demonstrated significant improvements in blood pressure (p <0.05), and 2 out of 7 trials (n:705) showed a significant reduction in anthropometric measurements (p <0.05). CONCLUSION: Nigella Sativa has proved to have a significant positive effect on lipid profile and glycaemic index. The results showed in the parameters of blood pressure and anthropometric indices are less convincing, as results were inconsistent across studies. Nigella Sativa can therefore be recommended as an adjunct therapy for metabolic syndrome.

CONTEXTE: Le syndrome métabolique, tel que défini par le National Cholesterol Education Panel-Adult Treatment Panel III (NCEP-ATP III), se caractérise par la présence d'obésité, de dyslipidémie, d'hypertension artérielle et d'intolérance au glucose. Il affecte 25% à 40% de la population adulte en Malaisie et est associé à d' autres affections médicales, notamment les maladies cardiovasculaires. L'objectif de cette revue systématique est d'évaluer les effets de Nigella Sativa sur des paramètres reflétant le syndrome métabolique, tels que le profil lipidique, la pression artérielle, la glycémie et les indices anthropométriques. MÉTHODES: Cette revue systématique a été réalisée en effectuant des recherches de publications pertinentes dans deux bases de données (PubMed et Scopus). La période de publication était limitée de janvier 2011 à décembre 2021. Les outils de la collaboration Cochrane ont été utilisés pour évaluer le risque de biais de chaque essai. RÉSULTATS: Six des huit essais contrôlés randomisés (n : 776) ont montré une amélioration significative du profil lipidique (p <0,05), cinq des sept essais (n : 701) ont montré une réduction significative des indices glycémiques (p <0,05), un des cinq essais (n : 551) a démontré des améliorations significatives de la pression artérielle (p<0,05), et deux des sept essais (n : 705) ont montré une réduction significative des mesures anthropométriques (p <0,05). CONCLUSION: Nigella Sativa a prouvé avoir un effet positif significatif sur le profil lipidique et les indices glycémiques. Les résultats concernant les paramètres de la pression artérielle et des indices anthropométriques sont moins convaincants, car les résultats étaient incohérents entre les études. Nigella Sativa peut donc être recommandée comme thérapie adjuvante pour le syndrome métabolique. MOTS CLÉS: Nigella Sativa, Graines de nigelle, Essai contrôlé randomisé, Syndrome métabolique.

Review of Malaysian medicinal plants with potential wound healing activity.

Wound is defined as the damage to biological tissues including skin, mucous membranes and organ tissues. The acute wound heals in less than 4 weeks without complications, while a chronic wound takes longer than 6 weeks to heal. Wound healing occurs in 4 phases, namely, coagulation, inflammatory, proliferative and remodeling phases. Triclosan and benzalkonium chloride are commonly used as skin disinfectants in wound healing. However, they cause allergic contact dermatitis and antibiotic resistance. Medicinal plants are widely studied due to the limited availability of wound healing agents. The present review included six commonly available medicinal plants in Malaysia such as Aloe barbadensis Miller, Carica papaya Linn., Centella asiatica Linn., Cymbopogon nardus Linn., Ficus benghalensis Linn. and Hibiscus rosa sinensis Linn. Various search engines and databases were used to obtain the scientific findings, including Google Scholar, ScienceDirect, PubMed Central and Research Gate. The review discussed the possible mechanism of action of medicinal plants and their active constituents in the wound healing process. In addition, their application in nanotechnology and wound dressings was also discussed in detail.

Effectiveness of herbal oral care products in reducing dental plaque and gingivitis: an overview of systematic reviews.

Introduction: Numerous clinical trials and systematic reviews have investigated the effectiveness of both herbal and conventional oral care approaches to reducing plaque and gingivitis. However, their findings vary and are inconsistent. Thus, the objective of this umbrella review is to compile data from systematic reviews and provide an overview of the effects of herbal oral care products on tooth plaque and gingivitis. Methods: A comprehensive search of the literature was performed in 6 databases for systematic reviews with or without meta-analyses, published up to 30 May 2023, without any language restrictions. Only clinical trials comparing herbal oral care products (in the form of mouthrinse or toothpaste) against standard oral care products or placebo were considered. Results: Some herbal oral care products, particularly in the form of mouthrinses, have a similar level of positive effect on plaque and gingivitis reduction and, thus, can be used as an adjunct to traditional dentifrices. However, the shorter duration of trials (<4 weeks) and reported publication bias in the clinical trials mean that these findings must be interpreted with caution. Conclusion: To accurately determine the impact of various herbal extracts on periodontal health, well-designed, long-term, and controlled trials that adhere to standardized protocols must be carried out.

Introduction: On a étudié l'efficacité d'approches de soins buccodentaires classiques et à base de plantes pour lutter contre la plaque dentaire et la gingivite dans le cadre de nombreux essais cliniques et revues systématiques. Toutefois, leurs conclusions ont été variables et incohérentes. Cette revue générale vise donc à compiler des données issues de revues systématiques et de présenter un aperçu des effets des produits de soins buccodentaires à base de plantes sur la plaque dentaire et la gingivite. Méthodes: On a procédé à une recherche documentaire exhaustive dans 6 bases de données pour effectuer des revues systématiques, avec ou sans méta-analyses, sans aucune restriction relative à la langue de l'étude, publiées avant le 30 mai 2023. Seuls des essais cliniques comparant des produits de soins buccodentaires à base de plantes (sous forme de rincebouche ou de dentifrice) à des produits de soins buccodentaires classiques ou à des placebos ont été envisagés. Résultats: Quelques produits de soins buccodentaires à base de plantes, en particulier les rince-bouches de ce type, ont des effets positifs comparables en matière de réduction de la plaque et de la gingivite et peuvent donc être utilisés en complément des dentifrices ordinaires. Toutefois, ces résultats doivent être interprétés avec prudence du fait de la durée relativement courte des essais (moins de 4 semaines) et du biais de publication signalé dans les essais cliniques. Conclusion: Pour déterminer avec précision les effets de divers extraits de plantes sur la santé parodontale, il est nécessaire d'avoir recours à des essais bien conçus, à long terme et contrôlés, qui respectent des protocoles normalisés.

Effect of Cymbopogon olivieri-based herbal vaginal product on bacterial vaginosis.

OBJECTIVE: Bacterial vaginosis is the most common vaginal infection in reproductive-age women. If it is not treated, the quality of life will be reduced. In this study, the herbal medicine product Cymbopogon olivieri was used for its treatment. METHODS: This study was conducted with 90 women. The patients were randomly divided into two groups of 45: Cymbopogon olivieri and metronidazole. The treatment period was 7 days for each group. Improvement status was determined by eliminating at least three out of four of Amsel's criteria. A new variable with two order levels (negative and positive) was constructed. This new variable shows the status of the treatment process. Chi-square and Fisher's exact tests were used to examine the relationship between the new variable and treatment status. RESULTS: The results demonstrate that Cymbopogon olivieri and metronidazole significantly reduced the burning, itching, malodor, abnormal vaginal discharge, pH, clue cell, and positive whiff test (p<0.05). The findings also demonstrate that neither treatment was statistically different from the other for at least three of Amsel's criteria. CONCLUSION: This study shows that the effect of Cymbopogon olivieri on bacterial vaginosis is similar to that of metronidazole. Hence, Cymbopogon olivieri is a suitable option to treat bacterial vaginosis.

The impact of herbal treatments on cervicovaginal human papillomavirus infection: a systematic review and meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to investigate the effects of herbal treatments on cervicovaginal human papillomavirus infection. METHODS: A comprehensive literature search was conducted in PubMed, Scopus, Science Direct, and the Cochrane Library until December 2023, following Cochrane guidelines. Data were analyzed using the Review Manager computer program (Version 5.4.1). RESULTS: Five randomized controlled trials involving a total sample size of 662 women were included in the study. The pooled odds ratio for individuals testing negative for human papillomavirus after herbal intervention among human papillomavirus-positive patients was 1.86 (95% confidence interval (CI) 0.64-5.43), according to the fixed-effects model. Three out of the five studies indicated a significant relationship. The relationship between positive human papillomavirus infection and herbal treatments, measured by the fixed-effects model, resulted in a pooled odds ratio of 0.41 (95%CI 0.17-1.01), reporting a significant association (p=0.05). Subgroup analysis revealed a significant reduction in the relationship between herbal treatment and atypical squamous cells of undetermined significance (OR 0.16, 95%CI 0.03-0.88, p=0.04) but no significant impact on the relationship between herbal treatment and low-grade squamous intraepithelial lesion (OR 0.33, 95%CI 0.01-8.77, p=0.51). CONCLUSION: The meta-analysis suggests that herbal treatments reduce human papillomavirus infections. While herbal treatments show a significant reduction in atypical squamous cells of undetermined significance, they do not significantly impact the regression of low-grade squamous intraepithelial lesions.

Periodontal host-modulation therapy with avocado/soybean unsaponifiables in rats with arthritis.

BACKGROUND: The aim of this study was to evaluate the effect of the avocado/soybean unsaponifiables (ASU) in the treatment of induced periodontitis in rats with experimental arthritis. METHODS: Sixty rats were randomly assigned to 4 groups according to the type of treatment and the systemic condition of the animals: CTR-S: healthy animals in which saline solution (SS) was administered; ASU-S: healthy animals in which ASU (0.6 mg/kg) was administered; AR/ASU-S: animals with induced arthritis in which ASU was administered; AR-S: animals with induced arthritis in which SS was administered. Periodontitis was induced by ligatures, maintained for 15 days. Subsequently, the treatment was performed by scaling with hand instruments. The SS and ASU were administered daily by gavage until euthanasia of the animals that occurred at 7, 15 or 30 days after the scaling procedure (N.=5 animals/group). Bone resorption, inflammatory infiltrate composition, and osteoclastogenesis were assessed. RESULTS: The AR-S group had greater bone loss, smaller amounts of fibroblasts and larger amounts of inflammatory cells than all other groups. In addition, the AR-S group had greater osteoclastogenesis in relation to the healthy animal groups. CONCLUSIONS: The use of ASU improved the healing pattern after treatment for experimental periodontitis in animals with arthritis reducing the periodontal bone loss.

Ethnobotany in Angola: The contribution of late 19th century christian missionaries to the knowledge of medicinal wild plants.

ETHNOPHARMACOLOGICAL RELEVANCE: Angola has an extraordinary plant diversity and a great ethnobotanical potential. However, there is a general lack of information about the first botanical explorations in the country and their contribution to the knowledge of the medicinal flora. AIM OF THE STUDY: The main aim of this study was to unveil the ethnobotanical legacy of José Maria Antunes and Eugène Dekindt, priests of the first Catholic mission in Huíla (Angola) and shed light on their contribution to the knowledge of medicinal wild plants of the country, including information on the uses, plant parts used, and preparation methods documented in the late 19th century. The findings are discussed considering recent ethnobotanical studies to offer a more comprehensive understanding of the historical and traditional uses of plants in Angola over the last two centuries. MATERIALS AND METHODS: Based on the information available in manuscripts and on the study of botanical collections preserved in herbaria of Portugal and Angola, we extracted relevant information about the species used in traditional medicine by the rural population of Huíla, the health conditions treated, and the mode of preparation and application. RESULTS: Our results revealed that Antunes and Dekindt conducted the first ethnobotanical study in Huíla, and documented a large number of medicinal wild plants. From these, we report 191 medicinal species, including 25 endemic and four introduced species, belonging to 56 plant families and 146 genera. Fabaceae family presents the highest richness of medicinal plants (39 taxa), followed by Rubiaceae (13), Asteraceae (10), and Apocynaceae (9). The illnesses reported were classified into 15 different categories, with the highest number of species (49) corresponding to unspecific conditions, such as general pains, chills, and fever. Thirty-seven species were reported for respiratory diseases, 31 for musculoskeletal problems, and 30 for digestive issues. Leaves were the most used plant part for medicinal purposes (84 species). Infusion was the most frequently described preparation method (40 species), followed by maceration (24 species), and powdering (36 species). CONCLUSIONS: The legacy of Antunes and Dekindt's work improves our understanding of Angola's botanical richness and traditional uses of plant resources. Our findings highlight the presence of unique medicinal resources in Angola, especially among endemic species, which hold the potential to improve the quality of life of rural communities. Moreover, our research underscores the lack of knowledge of medicinal species, emphasizing the risk of losing valuable historical information.
