This document discusses masi kalpana, a process for preparing carbonized medicinal drugs for external use. Masi kalpana preparations have two main preparation methods - closed and open. The closed method involves finely powdering the drug, placing it in a container, sealing it, and subjecting it to heat treatment. The open method involves roasting the powdered drug in an open pan with stirring until it turns black. Examples provided are triphala masi for treating wounds and hastidanta masi for conditions like khalitya. Masi kalpana has an infinite shelf life if stored properly in airtight containers.
