Kilembe Benjamin Z. Gbolo Domaine T. Mwanangombo Clement L. Inkoto Emmanuel M. Lengbiye Clement M. Mbadiko Aristote Matondo Gedeon N. Bongo Dorothée D. Tshilanda <p><strong>Aims: </strong>A novel β-coronavirus (2019-nCoV) has become a pandemic affecting hundreds of thousands of people worldwide. Since there is no effective treatment, the need of finding alternative methods which can help to curb this pandemic is urgent. This study aims to review the literature on the virucidal and cytotoxic properties of <em>Aloe vera</em>, one of the most studied plants considered as a nutraceutical in order to propose it as an alternative solution against COVID-19.</p> <p><strong>Methodology:</strong> The literature review was based mainly on the COVID-19 resources that have been made freely available to the scientific community but also on the usual databases such as Pubmed and Google scholar.</p> <p><strong>Results:</strong> The literature review shows that the plant has antiviral activity on several types of virus (Haemorrhagic Viral Rhobdavirus Septicaemia, Herpes simplex virus type 1, Herpes simplex virus type 2, Varicella-Zoster virus, human immunodeficiency virus, Influenza virus, poliovirus, Cytomegalovirus, Human papillomavirus) including coronavirus SARS-CoV-1. The plant is consumed orally in several forms and is safe. It is possible that&nbsp; molecules of this plant that have already shown effectiveness on other viruses by some mechanisms such as interaction of virus enzyme, breakdown of the viral envelope etc. could participate in the action of the plant. Also, the presence of minerals such as Zinc, which have shown an effect on SARS-CoV-1, could be involved in the antiviral effect of <em>Aloe vera</em>.</p> <p><strong>Conclusion:</strong> Molecular docking of the main molecules of <em>Aloe vera</em> with SARS-CoV-2 protease is in progress and clinical trials are necessary to confirm the activity of <em>Aloe vera</em> on COVID-19.</p> 2020-05-24T00:00:00+00:00 ##submission.copyrightStatement## http://journalejmp.com/index.php/EJMP/article/view/30255 Phytochemical, Antioxidant and Safety Evaluation of Hura crepitans (L.)

However, most, including <em>Hura crepitans</em> (HC), have not been toxicologically evaluated. The present study was aimed at determining the phytoconstituents of HC, their antioxidant potentials and safety in animals.</p> <p><strong>Place and Duration: </strong>The study was performed at the Department of Biochemistry and Biotechnology, KNUST, Kumasi and subacute toxicity studies lasted for 14 days.</p> <p><strong>Materials and Methods: </strong>Hydroethanolic extracts and fractions of the leaves and stem back of HC were assessed for their phytochemical constituent,DPPH and FRAP scavenging activities and total phenolic and total flavonoid content. The acute and sub acute oral toxicity of the hydroethanolic stem back of HCin animals was evaluated using standard methods to establish the LD<sub>50</sub>, effect on weight, haematological and biochemical parameters.Phytochemical characterization was achieved using standard methods.</p> <p><strong>Results:</strong> The study showed that HC contained tannins, saponins, flavonoids, coumarins, glycosides, and triterpenoids. The hydroethanolic extract of the stem bark (EES) showed the greatest antioxidant potential. The LD<sub>50 </sub>estimate of the hydroethanolic extract of stem back was greater than 5000 mg/kg body weight/oral route, while the doses used in this study up to 1000 mg/kg body weight/oral route was safe. The extract generally did not cause any significant decrease in the weight of animals nor were there significant differences in relative organ weights in treated animals compared to the normal group. Haematology, liver function, kidney function, and serum electrolyte parameters were within the normal ranges in treated animals when compared to the control group.</p> <p><strong>Conclusion:</strong> The results showed that oral administration of hydroethanolic extract of <em>Hura crepitans</em>in animals up to 1000 mg/kg body weight is considered safe as it causes no significant derangement in clinical and haemato-biochemical parameters measured.</p> 2020-05-07T00:00:00+00:00 ##submission.copyrightStatement## http://journalejmp.com/index.php/EJMP/article/view/30256 In vitro Activity of Ozoroa pulcherrima Schweinf.

Oni <p>Majority of people in developing countries rely on Traditional Medical Practitioners (TMPs) or herbalist, hunters and community elders for the treatments of various diseases and illness due to their vast knowledge of medicinal plant usage. There is need to protect the flora and fauna and also the knowledge database often stored in the memories of elders, ancestral and traditional healers. Ethnobotanical study of medicinal plants used in the treatment of cough was carried out in Akinyele Local Government with the aim to document plants and indigenous knowledge of local people in the treatment of cough. Eight villages were selected purposively due to the relics of forest in those villages. The villages are Ijaye, Onidundu, Otunagbakin, Moniya, Idi- ose, Apapa, Aroro and Olanla. Respondents were stratified into 2 strata in each of the villages, namely Traditional Medical Practitioners (TMPs) or herbalist and hunters. Within each stratum, a random selection of 10 respondents were carried out thereby making 20 respondents in each village and total number of&nbsp; 160 respondents as sample size. Semi structured questionnaire was used to obtain information from the respondents. The interview was conducted one-on-one using the local language (Yoruba). The data collected were analysed using descriptive statistics. The result showed that a total number of 16 plants belonging to 13 families were recorded and enumerated along with their botanical name, family and local name. Information on methods of preparation of the recipes, plant part used, form in which plant part is used, mode of administration, dosage and shelf life were also documented. There is need for domestication and conservation of these plants to prevent their extinction. The bioactive compound in some of these plants can be synthesized together to produce conventional drugs for cough. Further studies should also be carried out on these plant species to obtain more information on their bioactive properties.</p> 2020-05-26T00:00:00+00:00 ##submission.copyrightStatement## http://journalejmp.com/index.php/EJMP/article/view/30264 Chemical Compostions of Essential Oils and Antimicrobial Activity of Hyptis suaveolens (L.)

Sureshbabu spbioinfo@yahoo.co.in E. Siddalingamurthy N. L. Shashidhara B. Sooryanarayanarao D. C. Bhavya <p>Natural plant medicines have been used as remedies for various diseases since ages. Various medical systems have been established and practiced across the world, of which some are gained popularity and constitutional recognition while some are yet to find recognition in certain geographical areas. Electrohomeopathy is one such medical practice which is picking up on acceptance by the Indian population. The Electrohomeopathy or Electropathic system of medicine has a history of nearly 150 years of existence. In India, the system has been in practice for more than a century. This is a purely plant-based medical system, first started by C.C. Mattei of Italy during the 1850s. Extraction of electrals or phytoconstituents from different plants and recombining in appropriate proportions as per the requirement of the patient’s disease condition forms the core principle of the system. In this review article, we briefly touch upon the origin, historical evolution, and basic principle, list of plants used, types of remedies used and current status in India and also throws light on what the future holds for the Electrohomeopathy medicine and treatment.</p> 2020-05-11T00:00:00+00:00 ##submission.copyrightStatement##
