The population of the East Region of Cameroon lives around the forest and shares precious knowledge about the medicinal plants they possess against diseases such as COVID-19 as the role of ethno-medicine may have favored resilience against the Covid-19 pandemic in Africa. The objective of this study was to identify medicinal plants used against Covid-19 by the local population through their knowledge of COVID-19 in the East Region of Cameroon. The sociodemographic profile, information on COVID-19, the medicinal plants used against COVID-19 and the symptoms were determined. An ethnobotanical survey was conducted from November 2025 to February 2026 across twenty-five (25) villages on 500 respondents. Demographically, a large proportion of the population were men (61.6%), most of whom were non-workers (70.2%), with a dominant age group of 41 to 50 years (35%). Seventy-one percent of the population claimed to know the means of transmission, with "shaking hands with an infected person" being the most cited (41%). Meanwhile, 67% claimed to know the symptoms, with "cough" being the most mentioned (47.4%). Regarding prevention, 68.4% knew of modern prevention methods, with 24.4% favoring social distancing. 52% of the surveyed population stated they had not contracted Covid-19 (with or without testing confirmation). Majority of the population preferred traditional medicine for their health care but only 20.6% of the respondents mentioned traditional treatments against COVID-19 which may be due to the fact that only 28.6% of the respondents had a good knowledge about COVID-19. Alstonia boonei De Wild. emerged as the most used medicinal plant in traditional Covid-19 treatments by the local population, with a citation frequency of 9%. This study sheds light on how local populations perceive, adopt, and adhere to public health crisis measures.
