Ethnobotanical study and vulnerability of medicinal plants used against the symptoms of COVID-19 in the Lomié subdivision, East Region of Cameroon.

Science has advanced to the point that traditional medicine is now a useful instrument for treating a wide range of human ailments. Indigenous peoples and local communities (IPLCs) do not, however, have access to the contemporary healthcare system. As a result, they turn to biological resources, which are the only readily available and accessible means of treating diseases like COVID-19 and flu outbreaks. In response to worldwide illnesses, this study aligns with the perspectives of traditional knowledge of biological resources, particularly therapeutic plants. Therefore, this study was aimed to document the use of the potential of medicinal plants by IPLCs in the Lomié subdivision to manage COVID-19 symptoms. In four villages in the Lomié subdivision Ekom, Payo, Eschiambor, and Kongo, ethnobotanical surveys, including semi-structured interviews on traditional usage of plants against Covid-19 symptoms, were carried out with 80 participants in order to meet all of the study specific objectives. For every species, a vulnerability index was established in order to evaluate the species fragility. To analyze the data, both descriptive and inferential statistics were applied. The findings show that the respondents are well aware of the symptoms of the COVID-19 and that gave them the ability to provide timely and efficient responses. The survey identified 43 species from 39 genera grouped in 28 families were used to treat COVID-19 symptoms, with bark being the most commonly used plant part (43.8%). Decoction was the most frequently used method of preparation (50%), and oral administration was the main route of administration (56.3%). Most of the plant species were harvested from secondary forests (44.2%), of which trees formed 48.8%. A total of 30 species were recorded to be vulnerable, with Entandrophragma cylindricum (Sprague) Sprague, Milicia excelsa (Welw.) Benth, Myrianthus arboreus P. Beauv., and Trichoscypha aborea (A. Chev.) A. Chev being the most vulnerable, with vulnerability index of 2.4. The results showed a strong non-causal relationship between vulnerability and the continuous and discontinuous explanatory parameters. The susceptibility of medicinal plants used to treat COVID-19 symptoms and the explanatory parameters had a statistically significant causal association, according to the binomial logistic regression model. In light of novel diseases like COVID-19, this study finds that traditional knowledge of medicinal plants is still widely held, especially among the indigenous and local population. It can also be very beneficial in the development of new medications for a variety of illnesses.

Termite Mushrooms (Termitomyces), a Potential Source of Nutrients and Bioactive Compounds Exhibiting Human Health Benefits: A Review.

Termite mushrooms have been classified to the genus Termitomyces, family Lyophyllaceae, order Agaricales. These mushrooms form a mutualistic association with termites in the subfamily Macrotermitinae. In fact, all Termitomyces species are edible and have unique food value attributed to their texture, flavour, nutrient content, and beneficial mediational properties. Additionally, Termitomyces have been recognized for their ethno-medicinal importance in various indigenous communities throughout Asia and Africa. Recent studies on Termitomyces have indicated that their bioactive compounds have the potential to fight against certain human diseases such as cancer, hyperlipidaemia, gastroduodenal diseases, and Alzheimer's. Furthermore, they possess various beneficial antioxidant and antimicrobial properties. Moreover, different enzymes produced from Termitomyces have the potential to be used in a range of industrial applications. Herein, we present a brief review of the current findings through an overview of recently published literature involving taxonomic updates, diversity, distribution, ethno-medicinal uses, nutritional value, medicinal importance, and industrial implementations of Termitomyces, as well as its socioeconomic importance.

Characterization of Firmiana colorata (Roxb.) leaf extract and its silver nanoparticles reveal their antioxidative, anti-microbial, and anti-inflammatory properties.

Nanotechnology is the integrative science in the field of physics, chemistry and biology. For the synthesis of silver nanoparticles, a simple approach was applied using Firmiana colorata (Roxb.) aqueous leaf extract. During the synthesis of this silver nanoparticle, the solution color changes from green to deep brown due to the reduction of silver. The phytocompounds present in the Firmiana colorata (Roxb.) leaf extract acts as a reducing as well as a capping agent. Identifying the presence of bioactive compounds responsible for the reduction of silver was extensively characterized by UV-Vis spectrophotometer, FTIR, SEM, and EDX. Moreover, to know the efficacy of the silver nanoparticles (AgNps) antioxidant and antimicrobial studies were evaluated against the human pathogenic bacteria. Furthermore, GC-MS analysis of the leaf extract of Firmiana colorata has been done followed by the in-silico molecular docking against the Anti-inflammatory and oxidative protein. Here within this study, a comparative evaluation was done among the Firmiana colorata (Roxb.) leaf extract and the synthesized silver nanoparticles. Results indicate that ethnomedicinally lesser known Firmiana colorata (Roxb.) and AgNps have the potency to act as anti-inflammatory, antioxidative, and antimicrobial agents.

Cultural significance of locusts, grasshoppers, and crickets in sub-Saharan Africa.

BACKGROUND: In sub-Saharan Africa, there is a wealth of information about insects which is often only orally available. The purpose of the study was to remedy this shortcoming and make an overview of how orthopteran species are utilised, perceived and experienced in daily life across sub-Saharan Africa. METHOD: Ethno-entomological information on Orthoptera in sub-Saharan Africa was collected by (1) interviews with more than 300 people from about 120 ethnic groups in 27 countries in the region; (2) library studies in Africa, London, Paris and Leiden; and (3) using web search engines. RESULTS: More than 126 species of crickets, grasshoppers, and locusts have been identified as edible in sub-Saharan Africa. Some toxic species, such as Zonocerus spp., are eaten by some groups who use processing and detoxifying techniques. The katydid Ruspolia differens is very popular as food in central and eastern Africa and is captured by indigenous and commercial methods. Vernacular names refer to their morphology, behaviour, characteristics or the beliefs associated with the insect. The aposematic pyrgomorphid species, such as Zonocerus spp., are often used as medicine. Children play with grasshoppers, by for instance herding them like cattle, and they consider cricket-hunting for food as a game. The doctrine of signatures probably plays a role, as crickets, because of their chirping, are used to improve the sound of a music instrument, or as medicine to treat earache. Locust plagues are considered a punishment which requires repentance, but also an opportunity to acquire food. Proverbs and stories relate to using the orthopterans as food or to the underground lives of the crickets. Possible explanations are given as to why so many practices, beliefs and stories about orthopterans are so widespread in sub-Saharan Africa. The relevance of recording such ethno-entomological practices is discussed. CONCLUSION: Grasshoppers, locusts and crickets, although they may be agricultural pests, are very popular as food. They are also used in medicine, and as toys, and they play a role in religion, art and literature.

Emerging paradigms of viral diseases and paramount role of natural resources as antiviral agents.

In the current scenario, the increasing prevalence of diverse microbial infections as well as emergence and re-emergence of viral epidemics with high morbidity and mortality rates are major public health threat. Despite the persistent production of antiviral drugs and vaccines in the global market, viruses still remain as one of the leading causes of deadly human diseases. Effective control of viral diseases, particularly Zika virus disease, Nipah virus disease, Severe acute respiratory syndrome, Coronavirus disease, Herpes simplex virus infection, Acquired immunodeficiency syndrome, and Ebola virus disease remain promising goal amidst the mutating viral strains. Current trends in the development of antiviral drugs focus solely on testing novel drugs or repurposing drugs against potential targets of the viruses. Compared to synthetic drugs, medicines from natural resources offer less side-effect to humans and are often cost-effective in the productivity approaches. This review intends not only to emphasize on the major viral disease outbreaks in the past few decades and but also explores the potentialities of natural substances as antiviral traits to combat viral pathogens. Here, we spotlighted a comprehensive overview of antiviral components present in varied natural sources, including plants, fungi, and microorganisms in order to identify potent antiviral agents for developing alternative therapy in future.

Cultural significance of Lepidoptera in sub-Saharan Africa.

BACKGROUND: The taxon Lepidoptera is one of the most widespread and recognisable insect orders with 160,000 species worldwide and with more than 20,000 species in Africa. Lepidoptera have a complete metamorphosis and the adults (butterflies and moths) are quite different from the larvae (caterpillars). The purpose of the study was to make an overview of how butterflies/moths and caterpillars are utilised, perceived and experienced in daily life across sub-Saharan Africa. METHOD: Ethno-entomological information on Lepidoptera in sub-Saharan Africa was collected by (1) interviews with more than 300 people from about 120 ethnic groups in 27 countries in the region; and (2) library studies in Africa, London, Paris and Leiden. RESULTS: Often the interviewees indicated that people from his or her family or ethnic group did not know that caterpillars turn into butterflies and moths (metamorphosis). When known, metamorphosis may be used as a symbol for transformation, such as in female puberty or in literature regarding societal change. Vernacular names of the butterfly/moth in the Muslim world relate to religion or religious leaders. The names of the caterpillars often refer to the host plant or to their characteristics or appearance. Close to 100 caterpillar species are consumed as food. Wild silkworm species, such as Borocera spp. in Madagascar and Anaphe species in the rest of Africa, provide expensive textiles. Bagworms (Psychidae) are sometimes used as medicine. Ancestors may be associated with certain dark nocturnal moths, but these are also considered to be responsible for armyworms plagues. The appearance of butterflies/moths can be associated with seasons or serve as predictor of events. There are many proverbs, songs and stories related to butterflies and moths. Lepidoptera are also an inspiration in art expressions. In dance, the movements of caterpillars are used as examples, while certain cocoons are used as rattles. CONCLUSION: Lepidoptera are found very appealing because of the striking appearance of the adults, their dramatic metamorphosis and the provision of silk and nutritious food. Besides, they are an inspiration in art and literature.

In vitro antibacterial and cytotoxic activity of leaf extracts of Centella asiatica (L.) Urb, Warburgia salutaris (Bertol. F.) Chiov and Curtisia dentata (Burm. F.) C.A.Sm - medicinal plants used in South Africa.

BACKGROUND: Compounds having both anticancer and antimicrobial activity have promising therapeutic potential due to their selective cytotoxicity and their potential to reduce the occurrence of bacterial and fungal infections in immune-compromised cancer patients. In our quest to find new antimicrobial agents with potent anticancer activity, the biological potential of leaves from the three medicinal plants Centella asiatica, Warburgia salutaris and Curtisia dentata as used by Zulu traditional healers for the treatment of cancer is investigated. METHODS: Extracts were assayed for antibacterial activity using the agar well diffusion and micro plate dilution assay. In addition, minimum bactericidal concentrations (MBC), lactate dehydrogenase (LDH) release assay and rhodamine 6G intake assay were used to ascertain the antibacterial activity. The cytotoxic effects of the plant extracts were determined using tetrazolium-based colorimetric (MTT) cell proliferation assay against MCF-7, human colorectal carcinoma cells (Caco-2), A549 and HeLa cancerous cell lines. RESULTS: The acetone extracts from Waburgia salutaris revealed noteworthy anti-proliferative effect yielding IC50 value of 34.15 µg/ml against MCF-7 cell line, while acetone extract from Curtisia dentata significantly (P ≤ 0.05) revealed promising IC50 values of 41.55, 45.13, 57.35 and 43.24 µg/ml against A549, HeLa, CaCo-2 and MCF-7 cell lines. The extracts further revealed a broad-spectrum antibacterial activity against bacterial strains used in the study. An acetone extract from W. salutaris revealed the highest zone of inhibition and the lowest minimum inhibitory concentration (MIC) of 21.0 mm and 0.16 mg/ml respectively against Staphylococcus aureus. Methanol extract from W. salutaris and ethyl acetate extract from C. dentata revealed 53% inhibition of R6G inside the cell against Staphylococcus aureus and Escherichia coli respectively in a cytosolic lactate dehydrogenase assay, suggesting that the mode of action of such extracts may be through efflux pump. CONCLUSIONS: Overall, the extracts had good antibacterial activity and anti-proliferative effects against selected cancerous cell lines. Given the good antibacterial activity of the extracts the plants may act as an immune booster and prevent infection in immunosuppressed cancer patients. This is further supported by the plants' anti-proliferative potential, bacteriostatic, bactericidal properties and also their ability to block bacterial efflux pump systems.

Cultural significance of termites in sub-Saharan Africa.

BACKGROUND: The number of termite species in the world is more than 2500, and Africa with more than 1000 species has the richest intercontinental diversity. The family Termitidae contains builders of great mounds up to 5 m high. Colonies are composed of casts: a queen, a king, soldiers and workers. Some species of termite cultivate specialised fungi to digest cellulose. Termites constitute 10% of all animal biomass in the tropics. The purpose of the study was to make an overview of how termites are utilized, perceived and experienced in daily life across sub-Saharan Africa. METHOD: Ethno-entomological information on termites (Isoptera) in sub-Saharan Africa was collected by: (1) interviews with more than 300 people from about 120 ethnic groups from 27 countries in the region; (2) library studies in Africa, London, Paris and Leiden. RESULTS: Vernacular names relate to mounds, insects as food, the swarming, and the behaviour of termites. Swarming reproductive, soldiers and queens are collected as food. There are many different ways to harvest them. Termites can also be used as feed for poultry or as bait to catch birds and fish. The mushrooms that grow each year from the fungus gardens on the termite mounds are eaten. The soldiers, the fungus gardens and the soil of termite mounds are used for multiple medicinal purposes. Mounds and soil of termites have numerous functions: for geochemical prospecting, making bricks, plastering houses, making pots, and for storage. Termite soil is often used as fertilizer. The act of eating soil (geophagy) among women, especially those that are pregnant, is practised all over Africa. The mounds can serve as burying places and are often associated with the spiritual world, especially containing the spirits of ancestors. Termites also play a role as oracle, in superstitious beliefs, in art and literature. CONCLUSION: The following characteristics make termites so appealing: the dominance in the landscape, the social organization, the destructive power, and the provision of food. The study shows that termites play a major role in peoples' lives, in physical as well as spiritual aspects.

Contributions to the phytotherapies of digestive disorders: Traditional knowledge and cultural drivers of Manoor Valley, Northern Pakistan.

ETHNO PHARMACOLOGICAL RELEVANCE: Ethno medicinal traditional knowledge regarding the uses of indigenous medicinal plants used for various human digestive disorders are mostly known to the elder community members. As the young generation is not much aware about such vital traditional medicinal practice because they rely on elders. AIM OF STUDY: To document, accumulate and widely disseminate the massive indigenous knowledge of century's practiced therapeutic uses of medicinal plants by the local people living in this remote area. MATERIALS AND METHODS: A total of 63 local inhabitants (39 males and 24 females) were interviewed through a structured questionnaire. The data obtained were quantitatively analyzed through the use value (UVi), fidelity level index (FL%) and relative frequency citations (RFCs), consensus index (CI%) and informant consensus factor (FIC). For novel uses all the plants were checked with previously published articles on same disease by analyzing through Jaccard index (JI) and Sorensen's similarity index (QS). Plants specimen were preserved, mounted and labeled on the herbarium sheets, cataloged and deposited with voucher numbers in Hazara University Herbarium, Mansehra, Pakistan (HUP). RESULTS: 44 plant species belonging to 44 genera and 28 families were documented in the current study. These medicinal plant species were used commonly as an ethno medicine against 26 various digestive disorders out of which most frequently occurred are; stomach ache, diarrhea, indigestion, constipation and inflammation etc. Herbaceous plant species were the dominant among plants studied which were 64% of the total plants, followed by trees (20%) and shrubs (16%). Lamiaceae was the leading family among collected medicinal plant species (13.6%). Maximum medicinal plant species were used for treatment of stomach ache (11.7%), diarrhea and indigestion (10.9% each). Most widely used parts were leaves (41% citations), fruit and whole plant (12% citations each) for medication of various digestive problems by the traditional drivers. Dominated medicinal plants with most use values were Ficus carica having (UVi=0.90) and Trifolium repens (UVi=0.84). Based on the RFC values, the most cited medicinal plant species by the traditional drivers were Ficus carica (0.43) and Berberis lycium (0.41), while most respondents percentage was noticed for same plant species calculated through consensus index (CI%=42.9% and 41.3%) respectively. The medicinal plant species with highest fidelity level was of Grewia optiva, Juglans regia and Sorbaria tomentosa each cited 100% for anthelmintic, easy digestion and Diarrhea respectively. Due to representation by only single medicinal plant taxa (Nt=1), the digestive diseases viz. cholera, colon cancer, emetic, internal injuries, kill microorganisms, Soothing, tumor and urine suppression had maximum FIC value. The analytical result reveals that 57% of medicinal plant species were reported for the first time regarding their uses. new medicinal uses of Anaphalis contorta, Caltha palustris, Pinus wallichiana, Plantago himalaica were recorded for the first time from Pakistan and Aralia cachemirica, Bupleurum longicaule, Pleurospermum stellatum, Potentilla argentea and Juglans regia across the globe for currently reported medicinal uses. Besides this, all the mentioned plant species were reported for the first time for digestive disorders from Manoor Valley as no single study up-till now has been conducted ethno medicinally. CONCLUSION: The present study revealed the importance to document and launch list of all the possible plants that are used in traditional medicinal practices against digestive disorders in the unexplored study area and to show the important medicinal plants for future biological, phytochemical and pharmacological experimentation regarding digestive problems.
