The Pharmacist's Manual: Measuring Medicine in Yogataraṅgiṇī
Yogataraṅgiṇī, an 18th-century Ayurvedic compendium, works out the whole system of weights — from a rājikā seed to a pala — and the exact ratios for cooking medicated oils.

This manuscript is the Yogataraṅgiṇī (also titled Laghuyogataraṅgiṇī), a medical treatise composed by Trimallabhaṭṭa in Samvat 1703, belonging to the Āyurvedic tradition of Indian medicine. The text systematically addresses the principles of disease diagnosis and treatment (cikitsā), discussing the three doṣas (vāta, pitta, kapha), their seasonal variations, bodily locations, and the qualifications required of physicians, patients, medicines, and attendants. The work emphasizes the integration of karma theory with medical practice, distinguishing between diseases arising from doṣic imbalance (doṣaja) and those originating from past actions (karmaja), while providing detailed guidelines for therapeutic intervention and the ethical responsibilities of the physician.
