Rasaratnasamuchchaya (रसरत्नसमुच्चय) is a major text of rasashastra, the branch of Ayurveda that purifies mercury, sulphur, mica, metals and gems and turns them into medicines. It is ascribed to Vagbhatacharya, usually called Rasa-Vagbhata to distinguish him from the author of the Ashtanga Hridaya.

The opening part describes the pharmacy, apparatus, crucibles, heating methods and technical terms, followed by the purification and incineration of the major and minor minerals, metals and gems. Later chapters give mineral formulations for treating particular diseases.

This edition was published in 1939 by the Chowkhamba Sanskrit Series Office, Benares, as No. 91 of the Haridas Sanskrit Series. It carries the Suratnojjvala Hindi commentary of Pandit Ambikadatta Shastri, Ayurvedacharya of Banaras Hindu University, with notes, introduction, indices and appendices. Each verse is followed by a plain Hindi explanation, and the book long served students and practising vaidyas. The opening leaves of this copy also carry a few remedies handwritten in Nepali by an earlier owner.
