Despite the growing importance of medicinal plants in health care, their use often remains empirical, and their scientific validation is still lacking. Monographs provide detailed information on medicinal plants, their characteristics, therapeutic uses and safety.As part of our ethnobotanical study, we identified ten medicinal plants most used by diabetic patients in the Rabat-Salé-Kénitra region in Morocco. These are Olea europaea, Trigonella foenum-graecum, Salvia officinalis, Origanum grosii, Allium cepa, Marrubium vulgare, Cinnamomum zeylanicum, Artemisia herba-alba, Rosmarinus officinalis and Coriandrum sativum. The present work aims to develop detailed monographs of these medicinal plants following the monograph model proposed by the WHO. Their content is based entirely on an exhaustive synthesis of the literature.The book is intended for researchers and scientists, health professionals, diabetic patients, and medicinal plant enthusiasts.
