This Sanskrit manuscript, titled *Rasamuktāvaliḥ*, is a specialized treatise on Ayurvedic alchemy (rasāyana) preserved in the Poona University Collection at the Bhandarkar Oriental Research Institute. The text provides detailed procedural instructions for the preparation of gold-based medicinal compounds, including methods for testing (*parīkṣā*), purification (*śodhana*), and incineration (*māraṇa*) of gold, as well as formulations for *bālamṛgāṅka* and *rājamṛgāṅka*—complex mercury-based preparations combined with gold and pearl. Notable for its precise metrological specifications and multi-stage calcination techniques using cow dung cakes (*gajapuṭa*), the text exemplifies the sophisticated intersection of metallurgical science and therapeutic practice in classical Indian medicine, with verses 20–23 delineating the pharmacological virtues (*guṇa*) and potential toxicities (*doṣa*) of processed gold ash (*hemabhasma*).
