Critical Review and Concept of Marana With Special Reference to Lauha

Abstract

Marana (Incineration) is an essential step to be performed on substances especially related to Rasashastra. It is very important pharmaceutical process, applicable to the original minerals/metals for their conversion into fine ash form (Bhasma form). Due to Marana, the minerals and metals are converted in such a form, So that, the same will not be converted back to its original form and will be easily absorbed and assimilated into body. This form of drug also called "Rasa'' form. The present paper gives the details of different Marana treatments and their applied aspect with special reference to Lauha. In the present paper an attempt is made to review and put forth the concept of Marana with special reference to Lauha bhasma. The information available in this review could be helpful to scientist, drug designers to do more Ayurvedic research towards concept of Marana. More literary research is needed on Marana to establish different bhasma claimed therapeutic potential.

Synthesis, Characterization, Biological Study of Synthesized Lauha Bhasma

“…The normal purification process was done in five steps which included Quenching in Sesame oil, Quenching in Butter Milk, Quenching in Cow Urine, Quenching in Rice Gruel, and Quenching in a decoction of Horse Gram [20], [21]. Special purification process was done in single step by Quenching in decoction in Triphala churna (Triphala kawath) [22].Marana was done in three steps which include Bhanupaka (exposure to sunlight), Sthalipaka (frying in the iron pan), and Putapaka (calcination) [23]. Lauha bhasma was subjected to various organoleptic and physicochemical analysis such as color, taste, texture, loss on drying,ash value, acid insoluble ash, and water-soluble ash [24].…”
