Background: The COVID-19 disease has affected more than 760 million people and caused more than 6,780,000 deaths worldwide. These numbers are likely to increase; however, the availability of the SARS-CoV-2 vaccine has slowed its rate of spread. On the other hand, several societies around the world have used many medicinal plants to prevent or treat this disease, particularly in regions with a long history of traditional medicine, like North African countries.Method: This study was conducted from February to November 2022 in three Algerian provinces (Bejaia, Bouira, and Tizi-Ouzou). The ethnobotanical information was obtained through a direct interview with 459 people cured of COVID-19. Results: In this investigation, 35 medicinal plants belonging to 21 families were registered, of which 74.29% are local and 25.71% are imported from other countries. The plants mostly used are Citrus limon L. (68.49%), Origanum vulgare L. (50%),
