Data obtained on patients with laboratory-confirmed 2019-nCoV infection in the hospital of Wuhan indicated that the common early symptoms of this disease were fever (98% of patients), cough (76%), and myalgia or fatigue (44%). The causal agent of this disease was isolated and identified by Chinese scientists as a new strain of Corona virus, the SARS-CoV-2 or 2019 novel corona virus (2019-nCov).
( 2020) reported in late December 2019, an outbreak of a mysterious pneumonia of unknown cause in the Huanan Seafood Wholesale Market, in Wuhan, Hubei, China. First discovered in the 1960s as parasites of infectious chicken bronchitis, they were later found to be responsible for serious epidemics in humans such as Severe Acute Respiratory Syndrome (SARS) in 2002/2003 and the Middle East Respiratory Syndrome (MERS) in 2012. Further applied research is needed to provide more scientific evidence for their efficacy, to establish standard formulations and clinical studies as part of efforts to develop therapies for COVID-19.īackground on the outbreak and epidemiology of the COVID-19 pandemicĬorona viruses are well known in veterinary medicine. The authors argue that Cameroonian medicinal plants can be of potential contribution to the fight against COVID-19. A PCA analysis showing cluster formatting among the recorded species indicates 4 groups of species and an array of possibility of using individual species or a combination of species for their complementary effects. Of these species, 30 contain confirmed antiCOVID-19 secondary metabolites, 90 are used traditionally to manage at least 3 common symptoms of COVID-19, 10 have immunostimulant activity, 52 have anti-inflamatory activity, 14 have antiviral properties and 78 species are documented as used to treat malaria. A total of 230 species was recorded as potential source of ingredients for the fight against the 2019 novel corona virus. Bibliographic information was searched in several databases (Google Scholar, PubMed, Scopus, ScienceDirect, PROTA, ResearchGate and GLOBEinMED), to retrieve relevant papers on (1) plants used to manage common symptoms of COVID-19, (2) plant secondary metabolites with confirmed inhibitory effects on COVID-19 and (3) plants exhibiting pharmacological activities of relevance for COVID-19 management. The purpose of this article is to review the medicinal plants with potential to be used as complementary therapies against COVID-19.
Since the outbreak in December 2019, in Wuhan (China) of COVID-19, approved drugs are still lacking and the world is seeking effective treatment.
