RESUMO
Yashada is one of the Sapta dhatu, which is chemically Zn, Yashada bhasma is used therapeutically in many diseases like Prameha, Pandu, Vatavyadi etc., in the form of Bhasma (ZnO). Objectives: To prepare Yashada bhasma and its physico-chemical analysis of Yashada bhasma. Materials and Methods: Yashada was subjected Samanya Shodhana, Vishesha Shodhana and Jarana as per Rasatarangini. Yashada marana was done as per Rasayana sara. Bhasma was subjected to physico-chemical analysis which mainly included classical Bhasma parikshas like Rekhapurnata, Varitara, Unama, Nischandrata etc and modern parameters like Acid Insoluble Ash, pH, Total Ash value etc and advanced analytical techniques like XRD, SEM and AAS. Results: After 1st Puta pale yellow colored Yashada bhasma passed classical Bhasma parikshas. In classical reference two Puta are mentioned so, the 2nd Puta was given. XRD reports shows major peaks which were identified as Zinc oxide (ZnO) compound. Hence indicates complete transformation of metal to Bhasma form. Scanning electron microscopy in Yashada Bhasma after 2nd Puta the particle size ranging from 5-10μm. AAS reports shows zinc percentage of 77.08% after 2nd Puta. Conclusion: Pale yellow coloured Yashada bhasma was prepared after two Gaja putas which passed the classical Bhasma parikshas.
RESUMO
Rasa Shastra is the pharmaceutical branch of Ayurveda. As like any other medical system, success of Ayurvedic treatment also depends upon quality of medicine prescribed to the patient. The integral part of Rasa Shastra lies in the successful pharmaceutical process. Bhasma are the potent Ayurvedic preparations prepared by metals and minerals. These Bhasma possess wide range of therapeutic efficacy and are considered superior because of their qualities like small dose, quick action, palatability and longer shelf life. Yashada bhasma is important formulation mentioned in Rasa shastra texts obtained from the incineration of Raw Yashada. The pharmaceutical procedures adopted in this study are Shodhana, Jarana, Marana. The present study has been planned to standardize the method of preparation of Yashada bhasma according to the method explained in the classical literature.
