ABSTRACT
Background: The rapid global spread of the COVID-19 pandemic urged scientists to search for effective and safe anti-coronavirus drugs from natural resources. Through centuries, traditional medicinal plants have been providing cure for diseases and general health care worldwide. Objective(s): The main aim of this review was to explore and summarize the research works on the different plants used traditionally in Sudan to treat signs and symptoms of COVID-19 and respiratory diseases, characterizing their antiviral activities and exploring the different phytochemicals present in these plants. Method(s): The current review was carried out in line with the recommendations of the PRISMA 2020 statement. Information on plants traditionally used in Sudan to treat the signs and symptoms of COVID-19 and respiratory diseases was obtained from traditional medicine books and published articles, as well as the daily practice by ordinary people. Result(s): This article illustrated the use of 27 plant species belonging to 15 families in Sudanese traditional medicine to treat signs and symptoms of COVID-19 and respiratory diseases. Legumi-nosae/Fabaceae was found to be the most represented family (7 species), followed by Combretaceae (3 species) and Capparidaceae and Malvaceae (2 species each). From these plants, about 11 plant species were studied for their antiviral activity against at least one virus, and 5 plants, namely Adan-sonia digitata, Boscia senegalensis, Hibiscus sabdariffa, Nigella sativa, and Mangifera indica, were tested for their antiviral activity against influenza viruses. The phytoconstituents of the listed plants were summarized, and the antiviral activity of their isolated bioactive compounds was highlighted. Conclusion(s): The review could provide an in-depth theoretical basis and valuable data for designing future studies.Copyright © 2023 Bentham Science Publishers.
ABSTRACT
Objective: This study was conducted to identify medicinal plants in the fight against Coronavirus disease, influenza and colds cited by travelers who came for their Covid test at the Institut Pasteur of C..te d'Ivoire. Methodology and Results: A semi-structured interview was conducted with 527 travelers from April 1 to June 30, 2021. The interviewed travelers were predominantly male (69.4%). Travelers going to France (28.46%) were the most numerous. The most represented age groups were 41-64 (43.83%) and 25-40 (43.26%). When the level of education is considered, the surveyed travelers have a higher level of education (89.94%). Entrepreneurs (13.85%), traders (12.66%), company directors (12.33%), students (8.54%) and health workers (6.45%) are the majority. Only 21.63% of travelers used traditional medicine in the last 12 months prior to the survey. Various plants are used to fight (33.43%) or prevent (56.57%) Coronavirus disease (7.02%), influenza (3.60%) and colds (2.84%). In total, 13 species of medicinal plants divided into 13 genera and 13 families were cited. Azadirachta indica (Meliaceae) with citation frequencies (cf) of 22%, Zingiber officinale (Zingiberaceae) with cf of 21% and Citrus limon (Rutaceae) with cf of 14% were the most cited species. Conclusion and application of results: These plants could be used for research and development of phytomedicines against Coronavirus, influenza and cold.
