ABSTRACT
This study was undertaken to identify herbal remedies that may be involved in the symptomatic management of COVID-19 disease. From a list of 247 medicinal plants, a bibliographic study was carried out with the richness, the floristic composition, the methods of preparation and use and the active principles of the plants as a variable. The importance value of these plants was also calculated. A Principal Component Analysis showed the links between the parts of plants used, the methods of preparation, the symptoms of COVID-19 disease that can be treated and the active ingredients. The results show that 226 medicinal plants divided into 190 genera and 79 families can be used to treat the symptoms of COVID- 19 disease namely otolaryngologic signs, pulmonary signs and general signs. Of these, twenty-eight (28) can relieve the majority of symptoms of COVID-19 disease. These symptoms are rhinorrhea, cough, fever, headache, vomiting, diarrhea, and muscle aches. These plants are mainly prepared in the form of a decoction and administered mainly orally. They mainly contain flavonoids, coumarins, alkaloids, tannins, steroids, terpenoids, saponosides, essential oils, mucilages, quinones, coumarins. The importance value of these plants is between 85.71 and 57.14%. The results also showed that eight (8) groups of medicinal plants can be distinguished according to the organs used, the methods of preparation, the symptoms of the COVID-19 disease treated and the active ingredients. The results of this study could serve as a database for the formulation of improved traditional drugs in the management of symptoms of COVID-19 disease in Cote d'Ivoire.
