Clinical Evidence of Magistral Preparations Based on Medicinal Cannabis Sara Arias, Marta Leon, Diego Jaimes and Rosa-Helena Bustos Pharmaceuticals, 2021, 14, 78, 1-13. Doi :10.3390/ph14020078   Abstract : Cannabis has been widely used as a medicinal plant for millennia; however, studies related to its main components were first conducted in 1960. Subsequently, laboratories have produced new components and structures related to its active biological properties. Countries that have approved the medicinal use of cannabis impose regulations that govern its clinical and scientific use. One means of administering medicinal cannabis is via a magistral preparation that must have a medical prescription and be prepared in an establishment [...]
