Sharangadhara Samhita
The primary classical text for Ayurvedic pharmacology (Dravyaguna) and formulation science (Bhaishajya Kalpana). Written by Sharangadhara (approximately 13th–14th century CE).

Editorial policy

How citations are handled on this site
Classical text citations follow the standard Sthana-Adhyaya-Sutra format (e.g., Charaka Samhita, Sutrasthana 4.7). Translated verses use standard scholarly English translations; the site does not claim original translation work. Modern research is cited where it documents the pharmacological basis for classically described properties — these citations are illustrative of mechanism, not claims of clinical efficacy for the conditions described.
