Bālatantra (Prayogasāra)

This Ayurvedic manuscript, titled *Prayoga Sara* (with a focus on *Balatantra*—pediatric medicine), is attributed to the author Kalyana and presents a systematic compendium of therapeutic practices. The text uniquely synthesizes diagnostic frameworks for reproductive and pediatric disorders, detailing etiologies of infertility, menstrual irregularities, and fetal health while prescribing pharmacopeial remedies derived from herbal, mineral, and animal-based ingredients. Its significance lies in the integration of humoral pathology (*tridosha* theory) with ritualistic and astrological considerations, reflecting the holistic epistemology of classical Ayurveda. Written in Devanagari script on aged paper, the manuscript preserves a complete, well-conditioned treatise that bridges empirical medicine and esoteric traditions, offering insights into premodern South Asian medical praxis.
