Vaidyarahasya: The 'Health-Giving Water' Remedy
Vaidyarahasya: water therapy, fever fasting, and a 17th-century compendium that absorbed syphilis into Ayurvedic medicine.

This 1698 Sanskrit medical manuscript, titled *Vaidyarahasyam* (The Secret of Physicians) by Vidyāpatiḥ, represents a significant 18th-century Ayurvedic compendium preserved in 87 folios. The text presents a systematic nosological framework covering 64 disease categories, ranging from fever (*jvara*) and digestive disorders to specialized conditions including *phirangaroga* (syphilis)—a notable inclusion reflecting early modern medical knowledge exchange. The opening verses establish theoretical foundations for fever management (*jvaracikitsā*), emphasizing therapeutic fasting (*laṅghana*) and hydrotherapy with detailed prescriptions for medicated waters (*ṣaḍaṅgodaka*), demonstrating sophisticated integration of humoral theory (*doṣa*) with individualized clinical protocols based on patient constitution (*bala*) and disease progression (*pāka*).
