INTRODUCTION: the use of medicinal plants has increased significantly in recent years. According to the World Health Organization, 80% of the world's population uses medicinal plants to treat themselves. Our study aims to estimate the prevalence of medicinal plant use by cancer patients, list the different plants and identify their adverse effects cited by users and their reported efficacy. METHODS: this study was realised among 100 patients via a questionnaire with 14-items. Socio-economic and clinical characteristics have been analysed. The bivariate and multivariate analyses have been used to demonstrate the association between the socio-demographic characteristics of the participants, the duration of the disease and the use of medicinal plants. RESULTS: 45% of participants used medicinal plants. The most commonly reported reason for using medicinal plants was cancer cure (22%). During this study, 32 plants were identified. The Honey was the most commonly used (25%), thyme was also consumed at 15%, fenugreek at 13% and garlic at 7%. According to the multivariate analysis, the residence is predictor of medicinal plant use, urban residents used medicinal plants more than rural patients with an OR: 3,098, IC, 95%: [1,183-8,113] and P = 0,021. Fifty patients reported the moderate efficacy of the use of medicinal plants, and 20% described some side effects such as abdominal pain in 34%. CONCLUSION: in order to avoid any interaction with oncological drugs and to improve their effectiveness, a great importance must be given to information, education and awareness sessions.
