Plants have been used for a long time ago by people to treat themselves. However, a few ethnic groups know their medicinal plants used, due to lack of ethnobotanical studies.
Our study was conducted during 28 June and 03 August 2014 in Noun Division located in western Cameroon. This study aimed to list the medicinal plants used in this division of our country.
