基金the joint project(2020-2023)between Department of Pharmacy of“G.d’Annunzio”University and Veridia S.r.l.aimed to the valorization of industrial hemp cultivation in the Middle Italy,Abruzzo Region.Project coordinators are Giustino Orlando,Luigi Menghini,and Claudio Ferrantefunded the industrial PhD project of Dr.Alessandra Acquaviva entitled:“Cannabis and circular economy:enhancing an agricultural supply chain with a high social impact,for the development of agroindustry through botanical innovations and related applications in the nutraceutical,pharmacological,cosmetic/cosmeceutical and health sectors in general”.Academic tutors are Giustino Orlando and Claudio Ferrantesupported by the Cristalfarma S.r.l.that funded the PhD project of Dr.Simonetta Cristina Di Simone entitled“From the Botanical Garden“Giardino dei Semplici”to modern rational phytotherapy:Enhancement of biodiversity and study of plant extracts in complex mixtures for innovative phytotherapeutic applications”.Academic tutors are Luigi Menghini and Claudio Ferrante.
